    TECHNICAL FIELD
    [001] The present disclosure relates to a refrigerant pipe attachment structure in a cooling structure to cool a cooling target with the refrigerant flowing through a refrigerant pipe. TECHNICAL HISTORY
    [002] A cooling mechanism, configured to cool a cooling target with refrigerant flowing through a refrigerant pipe is conventionally known. For example, Patent Document 1 discloses a cooling structure in which a cooling target is an electrical component of an air conditioner.
    [003] Specifically, the cooling structure of Patent Document 1 includes a heat transfer member in which a groove having an arc-shaped bottom surface, and a retaining member configured to press a refrigerant tube against the heat transfer member. The retaining member is, for example, an elastic clip with a U-shaped cross section, opening to one side close to the refrigerant pipe. The refrigerant tube is inserted into the elastic clip through its opening. Due to the elastic force of the elastic clip, the refrigerant tube is tilted towards the heat transfer member. As a result, the refrigerant tube is pressed against the heat transfer member, and the thermal resistance between the refrigerant tube and the heat transfer member is reduced. Additionally, JP H01 145 136 U reveals a set in which a cold plate is attached to an integrated circuit box, an internal part of the screw is provided in the integrated circuit box, and in which the cooling tubes are mounted on the cold plate, a screw being fixed through the cold plate and part of the internal screw, in order to simultaneously assemble / disassemble the cold plate and the cooling tubes. CITATION LIST PATENT DOCUMENT
    [004] PATENT DOCUMENT 1: Unverified Japanese Patent Publication No 2010-114115 SUMMARY OF THE INVENTION TECHNICAL PROBLEM
    [005] The retaining member of Patent Document 1 is formed like the elastic clip above, so that a long plate that extends in a direction perpendicular to the refrigerant pipe is curved into a U-shape. However, in that member of retention, the area of the compression part in which the refrigerant pipe is pressed against the heat transfer member is relatively small. As a result, there is a disadvantage that compression of the refrigerant pipe with insufficient force results in a reduction in the holding power of the refrigerant pipe and an insufficient reduction in the thermal resistance between the refrigerant pipe and the heat transfer member.
    [006] The present disclosure was made in view of the aforementioned and aims to propose a refrigerant tube fixing structure, in which a refrigerant tube can be held firmly and the thermal resistance between the refrigerant tube and a member heat transfer can be reduced sufficiently. SOLUTION TO THE PROBLEM
    [007] A refrigerant pipe attachment structure according to the present invention is alternately deformed by combining the characteristics of claim 1 or claim 7. The dependent claims refer to preferred embodiments.
    [008] A first aspect of the invention is intended for a refrigerant pipe attachment structure to cool a cooling target. The refrigerant tube attachment structure includes a heat transfer member (70) formed with an elongated groove (72) into which a refrigerant tube (15) is fitted, attached to a printed circuit board (61) by means of a fixing member (52) so that the heat transfer member (70) and the printed circuit board (61) fit a cooling target between them, and thermally contacts the cooling target (63), the fixing member (52) being fixed to the printed circuit board (61); an elastic member (80) formed in the form of an elongated plate that extends along a direction of extension of the refrigerant tube (15) and which includes part facing the tube (82) facing the refrigerant tube (15) ; and a compression mechanism (90) configured to provide a pressure force to press the elastic member (80) towards the heat transfer member (70) and to release the spring beam member (80).
    [009] In the first aspect of the invention, the refrigerant tube (15) is maintained between the groove (72) of the heat transfer member (70) and the part facing the tube (82) of the elastic member (80). The heat generated from the cooling target (63) is transmitted to the heat transfer member (70) and the refrigerant pipe (15), in that order, and then is applied to the refrigerant flowing through the refrigerant pipe (15 ). Thus, the cooling target (63) is cooled.
    [0010] The heat transfer member (70) of the present disclosure is formed in the form of an elongated plate that extends along the direction of extension of the refrigerant tube (15), and, likewise, the groove (72) of the elastic member (80) is also formed in the elongated form. Thus, when the elastic member (80) is pressed towards the heat transfer member (70) by the compression mechanism (90), a contact area between the elastic member (80) and the refrigerant tube (15) and a contact area between the refrigerant pipe (15) and the groove (72) is relatively increased.
    [0011] A second aspect of the invention is intended for the refrigerant pipe attachment structure of the first aspect of the invention, in which at least one curved part (86) extends along the direction of extension of the refrigerant pipe (15 ) is formed on the elastic member (80).
    [0012] In the elastic member (80) of the second aspect of the invention, the curved part (86) extending in the direction of extension of the refrigerant tube (15) is formed. Thus, the elastic member (80) has greater stiffness in a longitudinal direction than in a wide direction. As a result, the elastic member (80) has sufficient stiffness in the longitudinal direction, although it has a certain degree of elasticity in the width direction.
    [0013] A third aspect of the invention is intended for the refrigerant pipe fastening structure of the first or second aspect of the invention, in which the part facing the tube (82) of the elastic member (80) is formed in a shape flat plate.
    [0014] In the elastic member (80) of the third aspect of the invention, the part facing the tube (82) facing the refrigerant tube (15) is formed in the form of a flat plate. Thus, the part facing the tube (82) pressed by the compression mechanism (90) is substantially in contact with the refrigerant tube (15) in its extension direction.
    [0015] A fourth aspect of the invention is intended for the refrigerant pipe attachment structure of any one of the first to the third aspects of the invention, in which the groove (72) includes a plurality of grooves (72) that are formed in the heat transfer member (70), and the refrigerant tube (15) includes a plurality of refrigerant tubes (15), each of which is fitted to a corresponding one between the grooves (72), and the elastic member (80 ) is formed in a single plate shape that extends along the grooves (72).
    [0016] In the heat transfer member (70) of the fourth aspect of the invention, each groove (72) is formed for a correspondent among the refrigerant tubes (15). The elastic member (80) is formed in the form of a plate which extends along the grooves (72). When the elastic member (80) is pressed towards the heat transfer member (70) by the compression mechanism (90), the refrigerant tubes (15) are held between the elastic member (80) and the heat transfer member heat (70).
    [0017] A fifth aspect of the invention is intended for the refrigerant pipe fastening structure of the fourth aspect of the invention, in which the grooves (72) include two grooves (72) formed in the heat transfer member (70), the the part facing the tube (82) of the elastic member (80) includes two parts facing the tube (82), each facing a correspondent between the two grooves (72), and the elastic member (80) still includes a target of compression (84) formed between the two grooves (72) and pressed against the compression mechanism (90).
    [0018] In the fifth aspect of the invention, each refrigerant tube (15) is maintained between the groove (72) of the heat transfer member (70) and the part facing the tube (82) of the elastic member (80). The compression mechanism (90) presses the compression target (84) of the elastic member (80) formed between the parts facing the tube (82) against the heat transfer member (70). Thus, the compressive force acts relatively similarly on the refrigerant tubes (15).
    [0019] A sixth aspect of the invention is intended for the refrigerant pipe attachment structure of any one of the first to fifth aspects of the invention, in which a heat transfer enhancement material (78) configured to enhance heat transfer it is interposed between the groove (72) of the heat transfer member (70) and the refrigerant pipe (15).
    [0020] In the sixth aspect of the invention, the heat transfer enhancement material (78) to enhance the heat transfer is provided in the groove (72) of the heat transfer member (70). As a result, the thermal resistance between the heat transfer member (70) and the refrigerant pipe (15) is reduced.
    [0021] A seventh aspect of the invention is intended for the refrigerant pipe fastening structure of any one of the first to the sixth aspects of the invention, in which a fitting groove (100) is formed in the heat transfer member (70 ), and the compression mechanism (90) includes an interlocking part (96, 123) removably engaged with the interlocking groove (100), a displaceable claw part (94, 125) disposed outside the elastic member (80 ), and a compression part (93, 124a) which is, by displacing the claw part (94, 125), displaceable between a first position in which the elastic member (80) is pressed and a second position in which the member elastic (80) is released.
    [0022] In the seventh aspect of the invention, since the fitting part of the compression mechanism (90) is fitted with the fitting groove (100) of the heat transfer member (70), the compression mechanism (90) it is releasably attached to the heat transfer member (70). In addition, a user operates the gripper part (94, 125) to move the compression part (93, 124a) between the first position and the second position, thereby easily switching between compression of the elastic member (80 ) and the release of the elastic member (80).
    [0023] An eighth aspect of the invention is intended for the refrigerant pipe attachment structure of any one of the first to the seventh aspects of the invention, in which a slit (80a) is formed in the elastic member (80).
    [0024] Once the slot (80a) is formed in the above configuration, it can be guaranteed that the elastic member (80) is along the straight parts of the tube (16). Thus, the slit (80a) easily equals the pressure applied to the refrigerant tube (15) of the elastic member (80).
    [0025] A ninth aspect of the invention is intended for the refrigerant pipe attachment structure of any one of the first to the eighth aspects of the invention, wherein the elastic member (80) includes a plurality of elastic members (80) arranged in the refrigerant tube extension direction (15).
    [0026] Since the plurality of elastic members (80) is provided in the above configuration, the pressure applied to the refrigerant tube (15) of the elastic members (80) can be easily equalized.
    [0027] A tenth aspect of the invention is intended for the refrigerant pipe attachment structure of any one of the first to the seventh aspects of the invention, in which a reinforcement ring (80b) is formed in the vicinity of part of the elastic member ( 80) pressed against the compression mechanism (90).
    [0028] In the above configuration, the stiffness of the elastic member (80) can be increased.
    [0029] An eleventh aspect of the invention is intended for the refrigerant pipe attachment structure of the fifth aspect of the invention, wherein the compression mechanism (90) is a screw (91), and a screw hole (75) having a shape composed of a large diameter part (75a) through which a screw head (91) passes and a small diameter part (75b) having this size so that the screw (91) can be tightened, is formed in the elastic member (80).
    [0030] In the above configuration, the elastic member (80) can be fixed temporarily. ADVANTAGES OF THE INVENTION
    [0031] According to the present disclosure, since the elastic member (80) extends in the direction of extension of the refrigerant tube (15), the contact area between the elastic member (80) and the refrigerant tube ( 15) can be expanded. Thus, it can be ensured that the refrigerant tube (15) is pressed against the heat transfer member (70), and the thermal resistance between the refrigerant tube (15) and the heat transfer member (70) can be reduced. Furthermore, since the groove (72) of the heat transfer member (70) extends in the direction of extension of the refrigerant tube (15), a sufficient heat transfer area between the heat transfer member (70) and the refrigerant tube (15) can be guaranteed. Thus, sufficient performance to cool the cooling target (63) can be guaranteed. Furthermore, according to the present disclosure, it can be guaranteed that the refrigerant tube (15) is maintained between the elastic member (80) and the heat transfer member (70).
    [0032] Particularly, in the second aspect of the invention, since the curved part (86) is formed in the elastic member (80), sufficient rigidity of the elastic member (80) in its longitudinal direction can be guaranteed. Thus, the compressive force acting on the elastic member (80) should probably be relatively uniform in the direction of extension of the refrigerant tube (15). As a result, sufficient holding power of the refrigerant pipe (15) can be guaranteed, and the thermal resistance between the refrigerant pipe (15) and the heat transfer member (70) can be reduced. Furthermore, the curved part (86) can guarantee a certain level of elastic properties in the width direction of the elastic member (80). Thus, the elastic member (80) can be sufficiently deformed towards the heat transfer member (70), and the desired compressive force can be obtained.
    [0033] In the third aspect of the invention, since the part facing the tube (82) of the elastic member (80) is formed in the form of a flat plate, the part facing the tube (82) and the refrigerant tube ( 15) may be in contact with each other in the direction of extension of the refrigerant pipe (15). Thus, even if the part facing the tube (82) pressed by the compression mechanism (90) is slightly inclined on the axis of the refrigerant tube (15), the contact aligned between the part facing the tube (82) and the refrigerant tube (15) is maintained. As a result, it can be ensured that the refrigerant tube (15) is pressed by the elastic member (80). Consequently, the holding power of the refrigerant pipe (15) can be further improved, and sufficient heat transfer between the refrigerant pipe (15) and the heat transfer member (70) can be guaranteed.
    [0034] In the fourth aspect of the invention, the plurality of grooves (72) are formed in the heat transfer member (70), and the elastic member (80) is formed along the grooves (72). Thus, the number of components, such as the heat transfer member (70) and the elastic member (80), can be reduced, and the refrigerant tubes (15) can be kept between the heat transfer member (70) and the elastic member (80).
    [0035] Particularly in the fifth aspect of the invention, the two refrigerant tubes (15) can be kept between the heat transfer member (70) and the elastic member (80). In addition, the compression target (84) is formed between the two grooves (72). Thus, the only compression mechanism (90) equals the compression force of the parts facing the tube (82) against the refrigerant tubes (15). As a result, the holding power of each refrigerant pipe (15) can be guaranteed, and the thermal resistance between each refrigerant pipe (15) and the heat transfer member (70) can be reduced.
    [0036] In the sixth aspect of the invention, the heat transfer enhancing material (78) can further reduce the thermal resistance between the refrigerant pipe (15) and the heat transfer member (70).
    [0037] In the seventh aspect of the invention, the following structure is employed: the fitting part (96, 123) of the compression mechanism (90) is removably fitted with the fitting groove of the heat transfer member (70) , and the claw part (94, 125) of the compression mechanism (90) is operated to alternate between the compression of the elastic member (80) and the release of the elastic member (80). Thus, fixation of the compression mechanism (90) and compression of the elastic member (80) can be carried out relatively easily. Consequently, the installation of the fixing structure for the refrigerant pipe (15) can be facilitated, and the degree of freedom of the layout of the refrigerant pipe (15) and the cooling target (63) is improved.
    [0038] According to each of the eighth and ninth aspects of the invention, since the pressure applied to the refrigerant tube (15) of the elastic member (80) can be easily equalized, the heat transfer between the refrigerant tube (15) and the heat transfer member (70) can be additionally guaranteed.
    [0039] According to the tenth aspect of the invention, sufficient force to press the tube can be obtained.
    [0040] According to the eleventh aspect of the invention, tightening the screw (91) can be facilitated. BRIEF DESCRIPTION OF THE DRAWINGS

The external art plate (81) is formed into a flat plate shape folded from the part facing the tube (82) towards the straight part of the tube (16) of the cooling tube (15).
    [0078] The part facing the tube (82) extends in the direction of extension of the straight part of the tube (16) of the cooling tube (15) so that it faces the straight part of the tube (16). That is, the pipe-facing portion (82) is formed in a position facing the pipe groove (72) of the refrigerant liner (70). The part facing the tube (82) is formed in the form of a flat plate so as to be substantially in contact with an outer circumferential surface of the straight part of the tube (16).
    [0079] The inner plate part (83) is formed closer to the middle of the spring beam member (80) in its wide direction in relation to the part facing the tube (82). The inner plate part (83) is formed into a flat plate shape folded from the part facing the tube (82) towards the straight part of the tube (16) of the cooling tube (15). The spring beam member (80) is provided so that the outer plate part (81), the part facing the tube (82), and the inner plate part (83) surround the straight part of the tube (16 ).
    [0080] The fixing plate part (84) is formed in the middle of the spring beam member (80) in its wide direction, so as to be interposed between the internal plate parts (83). The fixing plate part (84) is formed in a flat plate shape that extends in the direction of extension of the straight part of the tube (16), and is formed along the middle part (74) of the refrigerant coating (70 ). In the center of the fixing plate part (84), a through hole (85) is formed corresponding to the screw hole (75) of the refrigerant liner (70).
    [0081] In the spring beam member (80), the folded parts (86) are formed in six points. Each curved part (86) is formed straight along a longitudinal direction of the spring bundle member (80). The six folded parts (86) include a pair of outer folded parts (86a), a pair of internal folded parts (86b), and the pair of V-shaped folded parts (86c). The outer curved part (86a) is formed between the outer plate part (81) and the part facing the tube (82), and the inner curved part (86b) is formed between the part facing the tube (82) and the inner plate part (83). The V-shaped part (86c) is formed between the inner plate part (83) and the fixing plate part (84). The V-shaped portion (86c) protrudes in a substantially V-shape towards the interior of the recess (73) of the refrigerant liner (70). The folded parts (86) function as reinforcement strips configured to increase the stiffness of the spring bundle member (80) in its longitudinal direction. Thus, the spring beam member (80) has greater stiffness in the longitudinal direction than in the width direction. Note that the curved part (86) can be formed, for example, in a substantially U-shape.
    [0082] In the present embodiment, the screw (91) serves as a compression mechanism (90) configured to press the spring bundle member (80) towards the refrigerant liner (70). The fixing plate part (84) serves as a compression target that is being pressed against the refrigerant liner (70) with the tightening of the screw (91). OPERATION
    [0083] The operation of the air conditioner (1) will be described with reference to FIGURE 1. The air conditioner (1) alternates between the air cooling operation and the air heating operation. AIR COOLING OPERATION
    [0084] In the air cooling operation, the compressed refrigerant in the compressor (34) is condensed in the outdoor heat exchanger (31). Condensed refrigerant passes through, for example, the open air expansion valve (33) in a completely open state and then flows to the cooling tube (15).
    [0085] In the operation of the compressor (34), the energy element (63) generates heat. The heat from the energy element (63) is transmitted to the refrigerant liner (70), the thermally conductive lubricant (78), and the cooling pipe (15) in that order and then is applied to the refrigerant inside the cooling pipe. (15). As a result, the energy element (63) is cooled and maintained at a predetermined temperature at which the energy element (63) is operable.
    [0086] The pressure of the refrigerant flowing from the cooling tube (15) is reduced in the interior expansion valve (23) and then that refrigerant is evaporated in the interior heat exchanger (21). As a result, the indoor air is cooled. The evaporated refrigerant flows to the compressor (34) and is then compressed. AIR HEATING OPERATION
    [0087] In the air heating operation, the compressed refrigerant in the compressor (34) is condensed in the interior heat exchanger (21). As a result, the indoor air is heated. Condensed refrigerant passes through, for example, the interior expansion valve (23) in a completely open state and then flows to the cooling tube (15). As in the air cooling operation, the refrigerant is used to cool the energy element (63). The pressure of the refrigerant flowing from the cooling pipe (15) is reduced in the outdoor expansion valve (33), and then that refrigerant is evaporated in the outdoor heat exchanger (31). The evaporated refrigerant flows to the compressor (34) and is then compressed. REFRIGERANT TUBE FIXING STRUCTURE
    [0088] In the fixing structure (50), the cooling tube (15) is fitted in each tube groove (72) of the refrigerant liner (70). In that state, the spring beam member (80) is arranged so that it faces the refrigerant liner (70). The position of the screw hole (75) of the refrigerant liner (70) and the position of the through hole (85) of the spring beam member (80) are adjusted together and then the screw (91) is tightened in the screw hole (75). This tightening of the screw is carried out in the state in which the front panel (41) is released from the housing body (40). After the refrigerant liner (70) and the spring beam member (80) are temporarily tightened together with the screw (91) outside the housing (40), the screw (91) is completely tightened with the cooling tube (15) being interposed between the refrigerant liner (70) and the spring beam member (80). As above, tightening the screw (91) can be facilitated.
    [0089] When the screw (91) is tightened, the fixing plate part (84) of the spring beam member (80) is pressed against the refrigerant liner (70). Likewise, the parts facing the tube (82) connected to the fixing plate part (84) are elastically deformed towards the refrigerant coating (70). In this state, the V-bent parts (86c) enhance the elasticity properties of the spring beam member (80) and, therefore, it can be guaranteed that the parts facing the tube (82) are displaced towards the coating of refrigerant (70). However, the bent parts (86) improve the stiffness of the spring beam member (80) in its longitudinal direction and, therefore, the pressure force acts relatively equally on the straight parts of the tube (16) in its extension direction . Furthermore, since the screw (91) is tightened in the middle of the fixing plate part (84) in its longitudinal direction, the pressure force of the spring bundle member (80) in its longitudinal direction is easily equalized.
    [0090] Since the fixing plate part (84) between the parts facing the tube (82) is pressed with the screw (91), the pressure force of the parts facing the tube (82) against the tube cooling unit (15) can be easily matched. In addition, since the two cooling tubes (15) can be pressed against the refrigerant liner (70) with the single screw (91), the number of components can be reduced and the number of assembly steps can also be reduced .
    [0091] As described above, each of the two cooling tubes (15) is deformed towards a corresponding one among the tube slots (72) of the refrigerant liner (70). Thus, the cooling tube (15) is pressed between each tube groove (72) of the refrigerant liner (70) and each part facing the tube (82) of the spring beam member (80). The spring beam member (80) is, as described above, pressed against the cooling tube (15) to reduce free space between the cooling tube (15) and the coolant jacket (70) and to reduce resistance between the cooling tube (15) and the coolant jacket (70). Furthermore, since the thermally conductive lubricant (78) is interposed between the cooling tube (15) and each tube groove (72), the minute clearance between the cooling tube (15) and each tube groove (72 ) can be filled with thermally conductive lubricant (78). Thus, the thermal resistance between the cooling pipe (15) and each pipe groove (72) can be further reduced.
    [0092] The spring beam member (80) has a certain degree of flexibility. Thus, even if the processing precision of the spring beam member (80) is slightly reduced, the cooling tube (15) can be pressed firmly by the spring beam member (80). In addition, each part facing the tube (82) is in the form of a flat plate. Thus, even if the part facing the tube (82) is slightly inclined on the axis of the cooling tube (15), the aligned contact between the part facing the tube (82) and the cooling tube (15) can be sustained. Consequently, it can be ensured that the cooling tube (15) is pressed against the refrigerant liner (70).
    [0093] The parts facing the tube (82) and the tube grooves (72) extend in the direction of extension of the straight part of the tube (16) of the cooling tube (15). Thus, a contact area between the part facing the tube (82) and the straight part of the tube (16) can be expanded, and sufficient pressure force on the straight part of the tube (16) can be guaranteed. Furthermore, it can be ensured that the cooling tube (15) is maintained between each part facing the tube (82) and each tube groove (72). In addition, a sufficient heat transfer area between the cooling pipe (15) and each pipe groove (72) can be guaranteed. Thus, in the present embodiment, an effect sufficient to cool the energy element (63) can be produced and the heat generation of the energy element (63) can be reduced.
    ADVANTAGES OF FIRST ACHIEVEMENT
    [0095] According to the first embodiment, the holding power of the cooling pipe (15) can be increased between the cooling pipe (15) and each pipe groove (72), and the heat transfer of the energy element (63) to the cooling tube (15) can be improved. Thus, it can be ensured that the energy element (63) is efficiently cooled. As a result, sufficient reliability of the energy conversion device (60) and the air conditioner (1) can be guaranteed. SECOND ACCOMPLISHMENT OF THE INVENTION
    [0096] An air conditioner (1) of a second embodiment of the present disclosure is different from that of the previous embodiment in a configuration of a fixation structure (50) for a cooling tube (15). Differences from the first embodiment will be described below with reference to FIGURES 5-9.
    [0097] In the air conditioning (1) of the second embodiment, an energy conversion device (60) is, referring to FIGURE 5, arranged so as to face a front panel (41), and the cooling tube (15) is arranged at the rear of the energy conversion device (60).
    [0098] In the power conversion device (60), a printed circuit board (61) is arranged at the rear of the front panel (41), and a power element (63) is arranged at the rear of the circuit board printed (61). The printed circuit board (61) is attached to a housing (40) by means of a support member (51). The support member (51) is attached, for example, to an upper panel of the housing (40) or another member, so that the front panel (41) is fixable / removable.
    [0099] A coolant jacket (70) is attached to a surface (rear surface) of the energy element (63). As in the first embodiment, the tube grooves (72) are formed on a surface (rear surface) of the refrigerant liner (70). A spring beam member (80) deforms the cooling tube (15) towards the refrigerant liner (70).
    [00100] Referring to FIGURE 7, a slot (100) is formed in the refrigerant coating (70) of the second embodiment. The slot (100) is formed in a part of the middle (74) of the refrigerant liner (70) so as to extend between both ends of the refrigerant liner (70) in a longitudinal direction thereof. That is, the plug-in groove (100) can be easily formed by extruding the refrigerant coating (70) in its longitudinal direction ...
    [00101] The groove (100) includes an external groove part (101) formed on a surface of the middle part (74), and an internal groove part (102) formed inside the middle part (74), so as to communicate with the external groove part (101). The outer groove part (101) and the inner groove part (102) are formed in the middle of the middle part (74) in a direction of their width. The central position of the outer groove part (101) in the middle direction of the middle part (74) and the central position of the inner groove part (102) in the middle direction of the middle part (74) are coincident. The width of the inner groove part (102) is greater than that of the outer groove part (101).
    [00102] In the spring beam member (80) of the second embodiment, an insertion hole (110) is, referring to FIGURE 8, formed in the middle of a part of the fixation plate (84) in a longitudinal direction thereof and in the middle of the fixing plate part (84) in a direction of its width. In a circumferential internal part of the insertion hole (110), a pair of rectangular parts (111) and a pair of arc-shaped parts (112) are alternately arranged, one by one, in a circumferential direction of the orifice. insertion (110). The rectangular parts (111) are arranged in a longitudinal direction of the slot (100), so that they face each other. A distance between the opposite sides (111a) of the rectangular parts (111) is substantially equal to the width of the inner groove part (102). The arc-shaped parts (112) are arranged perpendicular to the longitudinal direction of the slot (100), so that they are facing each other. A graduated part (112a) protruding inwardly, in a radial direction, from the arc-shaped part (112) is formed in the middle of each arc-shaped part (112) in its circumferential direction.
    [00103] Referring to FIGURES 6, 7, and 9, a compression mechanism (90) of the second embodiment is a rotating fastener (92). The rotating fastener (92) includes a cylindrical body (93), a clamping plate (94) formed at one end of the body (93) in an axial direction of its own, a rotating rod (95) formed at the other end of the body (93 ) in its axial direction and a pair of protruding pins (96) formed at a tip end of the rotating rod (95).
    [00104] The clamping plate (94) is formed in the form of an elongated plate that extends outwardly in a radial direction of the body (93), so as to pass through the center of the body (93). The grip plate (94) serves as a claw part disposed outside the spring beam member (80). The grip plate (94) is pivotally displaced between a position indicated by a two-point chain line in FIGURE 6 and a position indicated by a solid line in FIGURE 6.
    [00105] The body (93) serves as a compression part configured to press the attachment plate part (84) of the spring beam member (80). Specifically, in the body (93), a pressure surface (93a) that contacts the part of the fixing plate (84) is formed on an end surface of the body (93) opposite the grip plate (94) in the axial direction of the body (93). With the rotation of the clamping plate (94), the body (93) is moved between the position (see a first position illustrated in FIGURE 6) in which the body (93) presses the spring bundle member (80) on the surface pressure (93a) and the position (i.e., a second position which is not shown in the figure) in which the spring beam member (80) is released from the pressure surface (93a).
    [00106] The rotating rod (95) is formed in a substantially circular cylindrical shape, so as to have a smaller diameter than the body (93). The rotating rod (95) is integrally formed with the body (93), so as to be coaxial to the body (93). The rotating rod (95) is inserted into the insertion hole (110) of the spring bundle member (80). Referring to FIGURE 9, a blocker (95a) is formed in the vicinity of the body (93) on an outer circumferential surface of the rotating rod (95). The blocker (95a) is a protrusion that protrudes out of the surface of the rotating rod (95) in a radial direction. The blocker (95a) contacts the graduated parts (112a) (see FIGURE 8) of the spring bundle member (80) to restrict the rotation of the rotating fastener (92). Thus, the rotating fastener (92) is prevented from rotating beyond a variation of rotation angle of about 90 °.
    [00107] A circular groove (95b) is formed in the vicinity of the body (93) on the outer circumferential surface of the rotating rod (95). A ring-shaped member (not shown in the figure), such as a washer or an so-called E-ring, is attached to the circular groove (95b) in the state in which the rotating rod (95) is inserted into the insertion hole (110) of the spring beam member (80). Thus, the spring beam member (80) can be integrally maintained with the rotating fastener (92).
    [00108] The protruding pins (96) protrude out of a part of the outer circumferential margin of the rotating rod (95) in its radial direction. The protrusion pins (96) are arranged with equal spacing. A protrusion direction of the protrusion pin (96) of the present embodiment is substantially coincident with a longitudinal direction of the grip plate (94).
    [00109] Each protrusion pin (96) in order to have a substantially trapezoidal cross section, perpendicular to the protrusion direction of the protrusion pin (96). More specifically, each protrusion pin (96) includes a rectangular surface (96a) that is substantially flush with a tip end surface of the rotating rod (95) and an inclined surface (96b), positioned closest to the body (93) and inclined in relation to the rectangular surface (96a). The inclined surface (96b) is inclined to approach the tip end surface of the rotating rod (95) in a direction of rotation (direction indicated by an arrow C in FIGURE 6) to secure the rotating fastener (92) to the refrigerant coating (70). The protrusion pins (96) serve as interlocking parts that can be interlocked with the rectangular parts (111) of the insertion hole (110) of the spring beam member (80) and the interlocking groove (100) of the refrigerant (70).
    [00110] In the second embodiment, a user rotates the rotating fastener (92) with the user holding the clamping plate (94), thereby easily maintaining the cooling tube (15) between the spring beam member (80) and the refrigerant coating (70). Specifically, the cooling tube (15) is interposed between the spring beam member (80) and the refrigerant liner (70) in the state in which the front panel (41) is released from a housing body (40). In this state, the user takes his hand to the rear of the cooling tube (15) and then inserts the protrusion pins (96) of the rotating fastener (92) into the slot (100) through the rectangular parts (111) of the insertion hole (110). That is, in the state in which the protrusion pins (96) are facing the longitudinal direction of the slot (100), the protrusion pins (96) are inserted into the inner groove part (102) until the protrusion (96) reach a lower part of the internal groove part (102). The clamping plate (94) in the above state (indicated by the two-point chain line in FIGURE 6) is rotated in the direction indicated by the arrow C. Thus, the inclined surfaces (96b) of the protrusion pins (96) are oriented to the along the arc-shaped parts (112), and the protruding pins (96) face a wide direction of the inner groove part (102) (see FIGURE 7). As a result, the protrusion pins (96) are kept inside the groove (100), and the rotating fastener (92) is moved towards the coolant liner (70), so that the body (93) presses on the spring beam member (80). As described above, when the fixing plate part (84) is pressed towards the refrigerant coating (70), a pair of parts facing the tube (82) are elastically deformed towards the cooling tube (15), as in the first realization. As a result, the cooling tube (15) is maintained between the spring beam member (80) and the refrigerant liner (70).
    [00111] In order to release the spring beam member (80), the clamping plate (94) is rotated in a direction opposite to the direction indicated by the arrow C in FIGURE 6. This brings the state in which the protruding pins (96) are along the outer groove part (101). In this state, the clamping plate (94) is pulled towards the rear (i.e., one side opposite the refrigerant liner (70)) to release the protrusion pins (96) from the slot (100). Thus, the spring beam member (80) is released.
    [00112] In the second embodiment, the structure in which the spring beam member (80) is pressed in such a way that the clamping plate (94) is rotated with the protrusion pins (96) being inserted into the slot (100) ) is used as described above. Thus, the spring beam member (80) can be easily released from the rear of the cooling tube (15). As a result, in the second embodiment, the energy conversion device (60) can be arranged in front (that is, close to the outside of the housing (40)) of the cooling tube (15), and the replacement and maintenance of components of the cooling tube. energy conversion device (60) are facilitated.
    [00113] Furthermore, in the second embodiment, the protrusion pins (96) of the rotating fastener (92) can be freely positioned along the internal groove part (102). That is, in the second embodiment, the positions of the protrusion pins (96) in relation to the refrigerant coating (70) can be freely determined and, therefore, installation is facilitated. THIRD ACCOMPLISHMENT OF THE INVENTION
    [00114] An air conditioner (1) of a third embodiment of the present disclosure is different from the previous embodiments in a configuration of a fixing structure (50) for a cooling tube (15). Differences from the second embodiment will be described below with reference to FIGURES 10-13.
    [00115] A slot (100) of a refrigerant liner (70) of the third embodiment penetrates the refrigerant liner (70) in a direction of its thickness. The slot (100) is formed in the center of a middle part (74). The slot (100) includes a pair of key slots (104) formed on a front side (i.e., a side next to a spring beam member (80)) of the refrigerant liner (70), and a circular cylindrical groove (105) formed at the rear of the key grooves (104).
    [00116] A compression mechanism (90) of the third embodiment is a lever clamp (120). The lever clamp (120) includes a circular cylindrical rod (121), a lever (122) pivotally supported at one end of the rod (121) in an axial direction through the rotating rod (121a), and a pair of keys (123) formed at the other end of the rod (121) in its axial direction.
    [00117] The lever (122) includes a discoid part (124) formed on the axis of the rotating rod (121a), and a lever body (125) that protrudes out of the discoid part (124) in a radial direction thereof . The lever body (125) serves as a gripper part that can be displaced out of the spring beam member (80). In the discoid part (124), an arc-shaped protrusion part (124a) that protrudes outwardly, in the radial direction of the discoid part (124), so as to be perpendicular to a direction of extension of the lever body (125 ) is formed. The arc-shaped protrusion part (124a) serves as a compression part which is, by displacement of the lever body (125), displaced between a first position (indicated by a solid line in FIGURE 13), in which the limb the spring bundle (80) is pressed, and a second position (indicated by a two-point chain line in FIGURE 13), into which the spring bundle member (80) is released.
    [00118] The rod (121) is inserted into the slot (100) through an insertion hole (87) of the spring beam member (80). The keys (123) are integrally formed with an outer circumferential surface of a tip end portion of the rod (121). Each key (123) is formed in a square prism shape, in order to be fitted to a corresponding one among the key slots (104). When the lever body (125) rotates over the center of the pole (121) in the state in which the keys (123) are inserted into the circular cylindrical groove (105) through the key grooves (104), the keys (123) are fitted in the circular cylindrical groove (105). That is, each key (123) serves as a removably engaged locking part with the locking groove (100).
    [00119] In the third embodiment, a user tilts the lever body (125), thereby easily maintaining the cooling tube (15) between the spring beam member (80) and the coolant jacket (70). Specifically, the cooling tube (15) is interposed between the spring beam member (80) and the refrigerant liner (70) with the front panel (41) being released from a housing body (40). In this state, the user takes his hand to the rear of the cooling tube (15) and then inserts the keys (123) of the lever clamp (120) into the key grooves (104). Subsequently, the rod (121) is rotated on its axis with the lever (122) being gripped. As a result, the keys (123) are adjusted and maintained within the circular cylindrical groove (105) (see FIGURE 11).
    [00120] Then, while the lever (122), in the state indicated by the two-point chain line in FIGURE 13, is being tilted in a direction indicated by an arrow G in FIGURE 13, the arc-shaped protrusion part ( 124a) is gradually pushing a part of the fixing plate (84) of the spring beam member (80). Likewise, the parts facing the tube (82) are elastically deformed towards the cooling tube (15), as in the second embodiment. As a result, the cooling tube (15) is maintained between the spring beam member (80) and the refrigerant liner (70).
    [00121] In order to release the spring beam member (80), the lever (122) is rotated in a direction opposite to the direction indicated by the arrow G in FIGURE 13. This releases the arc-shaped protrusion part (124a ) of the fixing plate part (84), thereby releasing the fixing plate part (84).
    [00122] In the third embodiment, the lever (122) is operated to easily fix the lever fastener (120) to the refrigerant liner (70). Thus, as in the second embodiment, the degree of freedom of layout of an energy conversion device (60) and the cooling tube (15) can be improved. As a result, the energy conversion device (60) can, as in the second embodiment, be arranged in front of the cooling tube (15), and replacement and maintenance of components of the energy conversion device (60) are facilitated. FOURTH ACCOMPLISHMENT OF THE INVENTION
    [00123] Referring to FIGURE 15, slits (80a) can be formed in a spring beam member (80). In the example of FIGURE 15, six slits (80a) are formed. Each slit (80a) is, in a direction perpendicular to the straight parts of the tube (16) of a cooling tube (15), formed on an outer plate part (81), a part facing the tube (82), and an inner plate portion (83) of the spring beam member (80). In this example, the spring beam member (80) is, in a part of its fixing plate (84), pressed against a refrigerant liner (70) with two screws (91).
    [00124] An increase in the length of the refrigerant liner (70) in an extension direction of the straight part of the tube (16) results in an increase in the length of the spring beam member (80) in the extension direction of the straight part of the tube. tube (16). Thus, it is difficult to match the pressure applied to the straight parts of the tube (16) by the spring beam member (80). On the other hand, since the slits (80a) are formed in the above configuration, it can be ensured that the spring bundle member (80) is along the straight parts of the tube (16). Thus, the pressure applied to the straight parts of the tube (16) by the spring beam member (80) can be easily equalized. As a result, the heat transfer between the cooling pipe (15) and the refrigerant liner (70) can be more guaranteed.
    [00125] Note that the shape of the slit (80a), as illustrated in FIGURE 15, has been established as an example. In addition, the number of slots (80a) and the number of screws (91) were also established as examples. FIFTH ACCOMPLISHMENT OF THE INVENTION
    [00126] Referring to FIGURE 16, a plurality of spring bundle members (80) can be provided for a single refrigerant liner (70). In this example, two spring beam members (80) are provided for a single refrigerant liner (70), so as to be arranged in an extension direction of a straight part of the tube (16). Each spring beam member (80) is, in a part of its fixing plate (84), pressed against the refrigerant liner (70) with a screw (91). In this configuration, even if the refrigerant liner (70) is formed, so as to be stretched in the direction of extension of the straight part of the tube (16), the pressure applied to the straight parts of the tube (16) by the spring beam members (80) can be easily matched. Thus, the heat transfer between a cooling pipe (15) and the refrigerant liner (70) can be more guaranteed.
    [00127] Note that the number of spring beam members (80) is not limited to two. The number of spring beam members (80) can optionally be determined depending, for example, on the size of the refrigerant coating (70). SIXTH ACCOMPLISHMENT OF THE INVENTION
    [00128] Referring to FIGURES 17 (A) and 17 (B), reinforcement rings (80b) can be formed in a spring beam member (80). The reinforcement rings (80b) are formed in the proximity of part (part of the fixing plate (84)) of the spring beam member (80), fixed with a screw (91). In the example of FIGURE 17 (A), eight reinforcement rings (80b) are formed in the part of the fixing plate (84), so as not to be positioned correspondingly to a screw hole (75). Each reinforcement ring (80b) has a substantially oval planar shape, and is formed on the attachment plate part (84) of the spring beam member (80). Each reinforcement ring (80b) is formed by beads (forming reliefs or projections) on the part of the fixing plate (84), and protrudes in a direction opposite to the refrigerant coating (70) (see FIGURE 17 (B)).
    [00129] For example, in the case where the spring bundle member (80) is thin, there is a possibility that the stiffness of the spring bundle member (80) is insufficient and sufficient force to press the straight parts of the tube (16) may not be obtained. In order to avoid this state, the thickness of the spring beam member (80) can be increased. However, this results in an increase in cost and unavailability of a material having a desired thickness. On the other hand, since the reinforcement rings (80b) are formed only in the middle part (part of the fixing plate (84)) of the spring beam member (80) in the present embodiment, the stiffness is increased only in the part of the middle of the spring bundle member (80) and therefore the spring bundle member (80) has increased stiffness as well as having elastic properties. Thus, sufficient force to press the straight parts of the tube (16) can be obtained. SEVENTH REALIZATION OF THE INVENTION
    [00130] FIGURE 18 is a view illustrating another configuration of a screw hole (75). FIGURE 19 is a view illustrating the state in which a spring bundle member (80), shown in FIGURE 18, is attached. In the present embodiment, a single screw hole (75) is, referring to FIGURE 18, formed in the spring beam member (80). The screw hole (75) is in a shape composed of a large diameter part (75a) through which a screw head (91) passes and a small diameter part (75b) having this size so that the screw ( 91) can be tightened.
    [00131] To tighten the spring beam member screw (80), it is necessary to keep one hand against the spring beam member (80) and tighten the screw (91) with the other hand using a wrench with the screw (91) being inserted into the screw hole (75). Thus, tightening the screw is difficult. On the other hand, since the shape of the screw hole (75), as described in the present embodiment, is employed, the assembly can be carried out, for example, in steps illustrated in FIGURE 20.
    [00132] In the example of FIGURE 20, the screw (91) is first tightened halfway in a refrigerant liner (70). Then, the spring beam member (80) is adjusted towards the screw (91), through the large diameter part (75a) of the screw hole (75) and then the fixing plate part (84) is slid so that the small diameter part (75b) reaches the screw (91). Subsequently, the screw (91) is tightened using a wrench. Since the spring beam member (80) can be temporarily fixed, as described above, the screw (91) can be easily tightened. OTHER ACHIEVEMENTS
    [00133] Previous achievements may have the following configurations.
    [00134] In each of the previous embodiments, a damper (130) can be arranged between the cooling tube (15) and the spring beam member (80) (see, for example, FIGURE 14). The damper (130) is made of, for example, a soft elastic material, such as rubber or synthetic resin. The damper (130) is formed in a plate shape or a plate shape that extends in a longitudinal direction of the cooling pipe (15), and is fixed on a surface of the cooling pipe (15). The damper (130) equals the pressure force acting on the cooling tube (15) on the side next to the spring beam member (80). In addition, the damper (130) prevents direct contact between the cooling tube (15) and the spring beam member (80), and prevents corrosion of the spring beam member (80) and the cooling tube (15) .
    [00135] In each of the previous embodiments, the thermally conductive lubricant (78) is interposed between the cooling tube (15) and each tube groove (72) of the refrigerant liner (70). However, a thermally conductive plate can, instead of the thermally conductive lubricant (78), be used as a material for enhancing heat transfer.
    [00136] In each of the previous embodiments, the two tube grooves (72) are formed in the refrigerant liner (70), and the cooling tube (15) is fitted in each tube groove (72). However, a single pipe groove (72) or three or more pipe grooves (72) can be formed in the refrigerant liner (70), and the cooling pipe (15) can be adjusted in each pipe groove (72) . In this case, the previous fixation structure (50) is also employed, and the cooling tube (15) can be maintained between the spring beam member (80) and the coolant jacket (70).
    [00137] In each of the previous embodiments, the air conditioner (1) includes the only indoor unit (20) and the only outdoor unit (30), as illustrated in FIGURE 1. However, a so-called “multiple air conditioner types ”which includes a plurality of indoor units (20) and a plurality of outdoor units (30) can be employed. Alternatively, other types of refrigeration equipment, such as freezers or water heaters, can be employed.
    [00138] In each of the previous embodiments, the refrigerant from the high pressure liquid channel flows into the cooling tube (15). However, refrigerant from a high pressure gas channel, a low pressure liquid channel or a high pressure gas channel can flow into the cooling pipe (15).
    [00139] In each of the previous embodiments, the energy element (63) of the energy conversion device (60) is provided as the cooling target. However, other types of alternating elements or electronic components can be provided as cooling targets. INDUSTRIAL APPLICABILITY
    [00140] As described above, the present disclosure is useful for the refrigerant pipe attachment structure in the cooling structure to cool the cooling target with the refrigerant flowing through the refrigerant pipe.
