    533 958 As a result, since the flow passage of the tube can not be tightly blocked from the outside, the heat exchanger performance may decrease and thus interruption and malfunction of the heat exchanger may reduce its economic efficiency.
    In addition, since a coupled area of the two bent ends of the sheet is very small due to the adhesion method, the coupled area can be easily deformed due to external shocks.
    At the same time, when the heat exchanger is installed in an apparatus such as a clothes dryer and circulating air containing moisture absorbed from drying clothes moves through the tube, since foreign substances such as fibers contained in the circulating air get stuck in the tube, the tube needs to be separated therefrom.
    Since the heat sinks can not be accurately fixed to the pipe when a user disassembles and cleans the heat exchanger and then reassembles the heat exchanger, the heat performance of the heat exchanger may decrease.

    DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below with reference to the accompanying drawings. The same reference numerals refer to the same elements through the application and further descriptions will therefore be omitted.
    Below, a heat exchanger in accordance with an embodiment of the present invention will be described with reference to the accompanying drawings.
    F ig. Fig. 1 is a perspective view of a heat exchanger in accordance with a first embodiment of the present invention, Fig. 2 is a perspective view showing an arrangement of a pipe and heat sinks of the heat exchanger in accordance with a first embodiment of the present invention, and Fig. 3 is a longitudinal view of a heat exchanger. cross-sectional view in a flow passage direction of the heat exchanger tubes in accordance with a first embodiment of the present invention. As shown in Figs. 1 to 3, the heat exchanger may include tubes 100, heat sinks 200, a front frame 300 and a rear frame 400.
    Said plurality of tubes 100 having flow passages 190 formed therein are spaced a predetermined interval from each other, and the heat sinks 200 may be arranged between the tubes 100.
    In addition, the front frame 300 and the rear frame 400 can be connected to both sides of the tubes 100 to fix the tubes 100 and the heat sinks 200.
    Each of the tubes 100 is provided by bending a plate several times to form the flow passage 190 therein, and coupling portions 180 are formed at a side surface 130 of the tube 100 and extend in the direction of the flow passage 190 by contacting one end of the plate with the other end of the plate.
    The tube 100 can be provided by bending a plate into a rectangular shape to form the flow passage 190 therein. Although the plate is not shown, a steel plate of a certain length, width and thickness is used to form the tube 100.
    In addition, the coupling members 180 are formed at a side surface 130 of the tube 100 and can be soldered or adhered by means of steel adhesive to seal the flow passage 190 of the tube 100 to the environment.
    As described above, since the coupling members 180 are sealed by means of adhesive or solder, leakage of a fluid passing through the flow passage to the environment can be prevented. In particular, the tube 100 can be formed by bending a plate into a channel shape comprising an upper surface 120, a side surface 130, a lower surface 140 and coupling parts 180.
    The tube 100 may have position guides 150 projecting from both sides of the upper surface 120 and the lower surface 140, and the heat sinks 200 may be arranged between the position guides 150 so that the coupling positions of the heat sinks 200 can be easily determined. In addition, as a consequence of this, it is possible to easily assemble them during production or for a user to reassemble them after disassembly, which thus improves the assembly performance of the heat exchanger.
    The position guides 150 can be formed on the tube 100 by a pressing process, or can be attached separately to the tube 100 by soldering, adhesives, etc.
    In addition, the tube 100 is formed by bending a plate into a rectangular shape to create the upper surface 120, the side surfaces 130 and the lower surface 140, and, at this time, the side surfaces 130 are formed on both sides of the upper surface 120 and the lower surface 140.
    The coupling members 180 may be formed at at least one of the side surfaces 130 by contacting one end of the plate with the other end of the plate of a predetermined length and extending toward the tube 100.
    The coupling members 190 can now be formed at a side surface 130 of the tube 100 and soldered or adhered by means of steel adhesive to tightly seal the flow passage 190 of the tube 100 to the environment.
    As described above, since the coupling members 180 are adhered by adhesives or solder, leakage of fluid passing through the flow passage to the outside can be prevented.
    In addition, the coupling members 180 extending toward the flow passage 190 can create a laminar flow of the fluid passing through the flow passage 190 and thereby improve the heat exchanger performance.
    Here, the laminar flow refers to a flow in which fluid is controlled by the coupling members 180 projecting inwardly toward the flow passage 190 to be vertically distributed and form an eddy current and increase the surface contact ratio at which fluid is in contact with an inner surface of the flow passage gene 190. 533 958 7 In addition, the coupling parts 180 bend in the direction of the flow passage 190 to increase a coupling area and prevent deformation thereof due to external shocks, unlike the conventional pipe where both ends are simply connected and offer a small connecting area. .
    As described above, the fluid (e.g., hot moist air generated after a drying process) may move through the flow passage 190 of the tube 100.
    At the same time, said number of pipes 100 can be stacked and separated at a predetermined interval from each other, and the heat sinks 200 are installed in the space between the pipes.
    In addition, the position guides 150 can project from both sides of the upper surface 120 and the lower surface 140 of the tube 100, and the heat sinks 200 can be arranged between the position guides 150.
    As a result, the heat sinks 200 can be positioned between the tubes 100 at predetermined intervals. In addition, the heat sinks 200 may have a specific cross-section in one direction, for example a waveform, etc. In this case, a plurality of heat sink passages 220 having a wave-shaped cross-section is formed, and another fluid (for example, dry outer air) may pass through the cooling flow passage 220.
    Furthermore, the front and rear frames 300 and 400 can be connected to both sides of the pipes 100, through which the pipes 100 and the heat sinks 200 can be connected closely to each other.
    Specifically, the front frame 300 can be connected to one side of the tubes 100, and the rear frame 400 can be connected to the other side. In this position, inlet 320 and outlet (not shown) can be formed on the front frame 300 and the rear frame 400, respectively, to correspond to both side shapes of the tubes 100.
    The number of inlets 320 and outlets can be formed to correspond to the range and number of tubes 100.
    As a result, both ends of the pipes 100 including the heat sinks 200 therebetween can be installed inside the inlets 320 and the outlets. Moist air generated in a drying process in any environment not limited to any particular case is passed through the inlet 320 into the inflow passage 190 of the tube 100 and then discharged through the outlet.
    Dry air led in from the environment moves simultaneously through the cooling flow passage 220 formed at the cooling flanges 200.
    The moist air and the dry air that are led in from the surroundings therefore do not mix with each other, and move across each other to indirectly exchange heat with each other.
    Since the moist air introduced into the tube 100 after the drying process is hot and the dry air introduced between the heat sinks 200 is relatively cold, the moist air can be condensed by heat exchange with the dry air so that the moisture is removed, and thus emitted as dry air.
    Fig. 4 is a perspective view showing an arrangement of a tube and heat sinks of a heat exchanger in accordance with a second embodiment of the present invention, and Fig. 5 is a longitudinal cross-sectional view in a flow passage direction of the heat exchanger tube according to a second embodiment of the present invention. the heat exchanger according to a second embodiment of the present invention will be described below with reference to Figs. 4 and 5.
    Only components of a tube and heat sinks of the heat exchanger that are different from those of the heat exchanger described with reference to Figs. 1-3 will be described, and description of components other than the tube and heat sinks will be omitted.
    As shown in Figs. 4 and 5, the heat exchanger comprises a plurality of tubes 500 having flow passages 590 formed therein and spaced a predetermined interval from each other, and the heat sinks 600 arranged between the tubes 500.
    In addition, the front frame (not shown) and the rear frame (not shown) can be connected to both sides of the tubes 500 to fix the tubes 500 and the heat sinks 600. 533 958 The front and rear frames (not shown) may have inner peripheries corresponding to the outer peripheries of the stacked tubes 500 and the heat sinks 600.
    Furthermore, each of the tubes 500 is provided by bending a sheet fl times to form a flow passage 590, and has coupling portions 580 formed at a side surface 530 of the tube 500 by contacting one end of the sheet with the other end of the sheet with a predetermined length and extending towards the flow passage 590.
    Specifically, the tube 500 may be shaped to assume an octagonal cross-section in a width direction thereof by bending the plate into an octagonal shape with slopes 521, 522, 541 and 542 formed at four corners to increase a penetration of fluid flowing into the heat sinks 600. Even if not shown, a steel plate of a certain length, width and thickness can be used to make the pipe 500.
    In addition, the coupling members 580 are formed at a side surface 530 of the tube 500 and may be soldered or adhered by steel adhesives to accurately seal the flow passage 590 of the tube 500 to the environment.
    As described above, the provision of coupling members 180 attached by means of adhesives or solder can prevent leakage to the environment of the fluid passing through the flow passage.
    In particular, the tube 500 can be provided by bending a plate into a channel shape comprising an upper surface 520, side surfaces 530, a lower surface 540 and coupling parts 580.
    Position guides 550 can project from both sides of the upper surface 520 and the lower surface 540 of the tube 500 so that the heat sinks 600 are located between the position guides 550 a coupling position of the heat sinks 600 can be easily determined. As a result, it is possible to easily assemble them during production or for a user to reassemble them after disassembly, thereby improving the assembly performance of the heat exchanger.
    The position guide 550 can be formed on the tube 500 by a pressing process, or can be attached separately to the tube 100 by means of soldering, adhesives, etc.
    In addition, the tube 500 is provided by bending a plate into an octagonal shape and has the upper surface 520, the side surfaces 530 and the lower surface 540. The side surfaces 530 are formed on both sides of the upper surface 520 and the lower surface 540.
    The slopes 521 and 522 may be formed at both sides of the upper surface 520 bent from one end of the side surfaces 530, and the slopes 541 and 542 may be formed at both sides of the lower surface 540 bent from the other ends of the side surfaces 530.
    In addition, coupling members 580 may be formed at at least one of the side surfaces 530 and project a certain length within the tube 500 by contacting one end of the plate with the other end of the plate.
    The coupling members 580 may be formed at a side surface 530 of the tube 500 by soldering or steel adhesives to tightly seal the flow passage 590 of the tube 500 from the environment.
    As described above, the provision of the coupling members 580 that are secured by adhesives or solder can prevent leakage of the fluid passing through the flow passage to the environment.
    In addition, the coupling members 580 extending toward the flow passage 590 can induce a laminate flow of the fluid passing through the flow passage 590 and thereby improve the heat exchanger performance.
    Here, the laminar flow refers to a flow where fluid is controlled by the coupling parts 580 which project inwards towards the flow passage 590 to be vertically distributed. generating an eddy current and increasing a surface contact ratio at which fluid is in contact with an inner surface of the flow passage 190. In addition, the coupling members 580 bend toward the flow passage 590 to widen a coupling area and prevent deformation thereof due to external shocks, to unlike the conventional pipe where both ends are easily connected to offer a small connection area. Upper surfaces 614 of the heat sinks 600 are correspondingly adhered to the lower surface of the upper tube 500 among said plurality of stacked tubes 500, and lower surfaces 612 of the heat sinks 600 are correspondingly adhered to the upper surface 520 of the lower tube 500.
    This means that the heat sinks 600 are arranged between the tubes 500 and adhered thereto and have different flange heights in the middle, one side and the other side thereof in accordance with the upper surface 520 and the lower surface 540 of the tube 500.
    Therefore, it is possible to significantly increase an amount of fluid introduced into a cooling flow passage 620 of the cooling fins 600 and exchange heat with fluid moving through said plurality of stacked tubes 500, thereby increasing the heat exchanger efficiency.
    The fluid (e.g. hot moist air generated in a drying process) can pass through the flow passage 590 of the tubes 500 in the manner described above.
    Said plurality of tubes 500 can be stacked at predetermined intervals and the heat sinks 600 are located in the space between the tubes 500.
    In addition, position guides 550 may project from both sides of the upper surface 520 and the lower surface 540 of the tubes 500, and the heat sinks 600 may be positioned between the position guides 550.
    As a result, the heat sinks 600 can be arranged between the tubes 500 at predetermined intervals.
    In addition, the heat sinks 600 may have a wavy cross-section in one direction. In this case, a plurality of cooling flow passages 620 having a wavy cross-section may be provided, and another fluid (e.g. dry external air) may pass through the cooling flow passages 620. In particular, the cooling flanges 600 are tightly arranged between the tubes 500 and have different flange heights a center, a side and the other side thereof in a longitudinal direction thereof to correspond to the upper surface 520 of the upper tube 500 and the lower surface 540 of the lower tube 500 of said plurality of stacked tubes 500 which are spaced apart. a predetermined interval from each other.
    Therefore, it is possible to markedly increase an introduced amount of fluid flowing into the heat sink passages 620 of the heat sinks 600 and improve the heat exchanger heat exchanger performance.
    Fig. 6 is a perspective view of a heat exchanger in accordance with a third embodiment of the present invention, and Fig. 7 is an exploded perspective view of the heat exchanger in accordance with a third embodiment of the present invention.
    As shown in Figs. 6 and 7, the heat exchanger may comprise tubes 10, heat sinks 20, a front frame 30 and a rear frame 40. Here, said plurality of tubes 10 with flow passages 19 formed therein are arranged at predetermined intervals, and the cooling vanes 20 may be arranged between the tubes 10. In addition, the front frame 30 and the rear frame 40 can be connected to both sides of the tubes 10 to fix the tubes 10 and the heat sinks 20. Position guides 15 can protrude from both sides of an upper surface 12 and a lower surface 13 of each of the tubes 10, and heat sinks 20 are arranged between the position guides 15 so that coupling positions of the heat sinks 20 can be easily determined. As a result, it is possible to easily assemble them during production or for a user to reassemble them after disassembly, which improves the assembly performance of the heat exchanger.
    Specifically, each of the tubes 10 has a channel shape to form a flow passage 19 therein so that a fluid can pass through the flow passage 19.
    The tube 10 can be provided by forming a plate by means of a mold tool but is not limited thereto but manufacturing can be done by various methods such as injection molding, etc. In addition, when the tube 10 is bent one side of the tube 10 can be rolled to form a roll form 18, but it is not limited thereto but can also be formed by various methods such as welding, soldering, adhesives, etc.
    In addition, said plurality of pipes 10 can be stacked and separated a predetermined interval from each other, and the heat sinks 20 can be arranged in the space between the pipes 10.
    In addition, position guides 15 can protrude from both sides of the upper surface 12 and the lower surface 13 of the tube 10 and the heat sinks 20 can be arranged between the position guides 15.
    As a result, the heat sinks 20 can be evenly distributed between the tubes 10.
    The heat sinks may have a corrugated cross-section in one direction. In this case, a plurality of cooling flow passages 22 having a waveform may be provided, and another fluid may pass through the cooling flow passages 22, which differ from the fluid passing through the tubes 10.
    In addition, the front frame 30 and the rear frame 40 can be connected to both sides of the pipes 10 in a position where the heat sinks 20 are arranged between the pipes 10.
    As described above, since the front and rear frames 30 and 40 are connected to both sides of the tubes 10, the tubes 10 and the heat sinks 20 are pressed against each other so that the tubes 10 and the heat sinks 20 can be tightly fixed against each other.
    In particular, the front frame 30 can be connected to one side of the tubes 10, and the rear frame 40 can be connected to the other side. The front frame 30 and the rear frame 40 may have inlets 35 and outlets 45 shaped to correspond to both sides of the tubes 10.
    In addition, the inlets 35 and the outlets 45 can be formed to correspond to the intervals between the pipes 10 and the number of pipe stacks, and thus the ends of the pipes 10 can communicate with the inlets 35 and the outlets 45. The inlets 35 and the outlets 45 can be connected to the ends of the pipes 10 in different ways. , not limited in a particular way, This means that the inlets 35 and the outlets 45 can be in continuous contact with and connected to the ends of the tubes 10, the inlets 35 and the outlets 45 can be inserted into the ends of the tubes 10 or the ends of the tubes 10 can be moved into the inlets 35 and the outlets 45.
    Since the position guides 15 are formed on both the side of the upper and lower surfaces 12 and 13 of the tubes 10, it is possible to increase the strength of both ends of the tubes 10 to a certain extent and prevent deformation of the two ends of the tubes 10. for example crumpling, etc.
    In addition, when the tubes 10 and the heat sinks 20 are connected to the front and rear frames 30 and 40, an additional upper plate 50 and a lower plate 60 may be installed at both outermost (upper and lower) sides of an assembly of the tubes 10 and the heat sinks 20.
    In addition, in order to more firmly fix the heat sinks 20, position guides 55 and 65 may be formed on both sides of a surface of the upper plate 50 and the lower plate 60 opposite the heat sinks 20.
    This means that the upper plate 50 may have the position guide 55 projecting downwards and the lower plate 60 may have the position control 65 projecting upwards.
    At the same time, moist air generated in a drying process in another of different environments, is not limited to any particular case, can be introduced into the inlet 35 to move through the tube 10, and then leave it through the outlet 45.
    At the same time, dry air introduced from the environment moves through the cooling flow passages 22 formed in the cooling flanges 20.
    Therefore, moist air and dry air introduced from the environment do not mix with each other and cross each other to indirectly exchange heat with each other. Since the moist air introduced into the tube 10 after the drying process is hot and the dry air introduced into the heat sinks 20 is relatively cold, the moist air can be condensed by heat exchange with the dry air so that the moisture is removed. and thus emitted as dry air.
    Fig. 8 is a perspective view of a pipe and heat sinks of the heat exchanger in accordance with a third embodiment of the present invention; Fig. 9 is a front view showing an mounted position of the pipes and heat sinks of the heat exchanger in accordance with a third embodiment. of the present invention, and Fig. 10 is a cross-sectional view taken along the line A-A in Fig. 8.
    As shown in Figs. 8-10, position guides 15 may be formed at both ends of the upper surface 12 and the lower surface 13 of the tubes 10 to project outwardly from the tubes 10.
    The position guides 15 are formed along a width direction of the tubes 10, and may have a length corresponding to the width of the heat sinks 20 so that the heat sinks 20 can be securely attached between the position guides 15 by contacting both sides of the heat sinks 20 therewith.
    In addition, the position guides 15 can protrude to a height to limit the heat sinks 20 so that they cannot overlap the position guides 15.
    In addition, the position guides 15 can be formed in one piece with the lower surfaces 13 and the upper surfaces 12, respectively.
    This means that the upper surface 12 and the lower surface 13 of each of the tubes 10 can be formed in one piece together with the position guides 15 so that the fluid moving through the tube 10 can pass therethrough by means of the position guides 15 without leakage from the tube. 10 to the surroundings.
    The position guides 15 can be formed at the tube 10 by means of a pressing process. In this case, the tube 10 can be provided by bending a plate. 533 958 16 In addition to facilitating the process, the position guides 15 can be pre-formed by a pressing process before the plate is bent to form the tube 10.
    In addition, the position guides 15 formed on both sides of the upper surface 12 and the lower surface 13 may be symmetrically shaped with respect to center portions of the upper surface 12 and the lower surface 13.
    In addition, the position guides 15 formed at the upper surface 12 may be symmetrically shaped with respect to the position guides 15 formed at the lower surface 13.
    As a result, the heat sinks 20 in contact with the upper surface 12 and the lower surface 13 can be controlled by and positioned between the position guides 15 to be located between said plurality of tubes 10 at predetermined intervals.
    Therefore, there is no need for an operator to make a separate marking for a coupling position for the heat sinks 20 on the pipes 10 or to use a positioning jig etc. in the manufacture of the heat exchanger. As a result, work performance and productivity can be improved.
    In addition, when a user disassembles and cleans the heat exchanger and then reassembles it, the assembly process can be more easily performed, since the heat sinks 20 can be easily positioned between the position guides 15.
    Both side ends E of the heat sinks 20 can be shaped to correspond to the lower ends 16 of the position guides 15, at which the heat sinks 20 are to be positioned.
    This means that when the lower ends 16 of the position guides 15 have a straight shape, the two side ends E of the heat sinks 20 attached to the lower ends 15 of the position guides 15 can also have a straight shape.
    As a result, the heat sinks 20 located between the position guides 15 correspond to the shape of the attachment regardless of the shape of the heat sinks 20, and thus different shapes of heat sinks can be applied without inclination or play. Fig. 11 is a perspective view of a tube of a heat exchanger in accordance with a fourth embodiment of the present invention. Various forms of position control can be applied to the heat exchanger in accordance with an embodiment of the present invention, and description of the same components as for the third embodiment will be omitted.
    As shown in Fig. 11, a plurality of position guides 915 in accordance with an embodiment of the present invention may be arranged in a width direction of a tube 910 at predetermined intervals. Although the number of position guides 915 formed on one side of the tube 910 is not limited, the position guides 915 may be formed at positions corresponding to the corners 925 of the heat sinks 920.
    As a result, the corners 925 of the heat sinks 920 located between the position guides 915 are positioned to be tightly adhered to the lower ends 916 of the position guides 915 so that the heat sinks 920 can be fixed to the tube 910 without any inclination or play.
    In addition, if necessary, additional position guides 915 can be formed between the position guides 915 formed at the positions corresponding to the corners 925.
    The heat exchanger including the above-mentioned embodiment can be used in various heat exchange apparatus such as clothes dryers for drying clothes.
    Fig. 12 is a schematic perspective view of a heat exchanger in accordance with a fifth embodiment of the present invention, and Fig. 13 is a schematic perspective view showing a pipe and heat sinks in accordance with a fifth embodiment of the present invention.
    As shown in Figs. 12 and 13, the heat exchanger may include tubes 710, heat sinks 720, a front frame 730 and a rear frame 740. The plurality of tubes 710 having flow passages 719 formed therein may be provided at predetermined intervals, and the heat sinks 720 533 958 18 may provided between the tubes 710. In addition, the front frame 730 and the rear frame 740 may be connected to both sides of the tubes 710 to secure the tubes 710 and the heat sinks 720. Spacers 716 and support members 717 are integrally formed with each of the tubes 710. at a central portion thereof to support the central portion of the tube 710, for the purpose of uniformly maintaining the shape of the tube 710.
    The tube 710 may be formed by bending a plate into a channel shape and may include a surface 712, side surfaces 713, the second surface 714 and the spacer 716.
    The terms one surface 712 and the other surface 714 are used to avoid limitation to an upper surface and a lower surface of the tube 710. When one surface 712 is the upper surface, the second surface 714 refers to the lower surface, and when one surface 712 the lower surface 714 refers to the upper surface 714.
    Hereinafter, for the sake of simplicity, one surface 712 will be referred to as the upper surface 712 and the other surface 714 will be referred to as the lower surface 714.
    The side surfaces 713 connected to both sides of the lower surface 714 as a bottom surface have a fixed height, and the upper surface 712 may be formed by extending from a side of the side surfaces 713 which are bent metrically parallel to the lower surface 714 with the same length to get in touch with each other.
    In addition, the spacers 716 may be formed by bending the contacted ends of the upper surface 712 toward the lower surface 714 at their center portion and adhering the bent ends together to place the adhered ends in vertical contact with the lower surface 714. .
    As a result, the spacers 716 may uniformly maintain an interval between the upper surface 712 and the lower surface 714.
    In addition, the spacers 716 may prevent deformation such as bending of the center portion of the lower surface 714 or the upper surface 712 of the tube 710 due to a small thickness (e.g., 0.3 mm) of the plate, which fixes the shape of the tube 710. 533 958 the thickness of the plate used to form the tube 710 is reduced to enable a weight loss of the tube 710, and thus the heat exchanger in which the tube 710 is installed may also become of light weight.
    The spacers 716 may have a length corresponding to the length of the side surfaces 713.
    The flow passages 719, both sides of which are open, can therefore be formed in the tube 710, through which fluid (for example hot moist air generated after the drying process) passes.
    In addition, the spacers 716 may include support members 717 extending from the ends of the spacers 716 toward the side surfaces 713 in opposite directions, and bottom surfaces of the elongate members may be in contact with the lower surface 714.
    As a result, the support members 717 may be adhered to the lower surface 714 to steadily support the lower end of the spacers 716 and prevent the ends of the spacers 716 from separating or bending from the center portion of the lower surface 714 which would cause bending or deformation. of the upper members 716 in a longitudinal direction of the tube 710. Although the length of the support members 717 is not particularly limited, they should have a length sufficient to prevent material loss and movement of the spacers 716 due to friction between the support members 717 and the lower member. surface 714.
    Said plurality of tubes 710 can be stacked at predetermined intervals and the heat sinks 720 can be arranged in the space between the tubes 710.
    The heat sinks 720 may have a wavy cross-section in one direction. In this case, a plurality of cooling flow passages 722 having wavy cross-sections may be provided, and another fluid (for example, dry outer air) may pass through the cooling flow passages 722.
    In addition, the front and rear frames 730 and 740 can be connected to both sides of the tubes 710, and the tubes 710 can be securely connected to the heat sinks 720 via the frames. 533 958 20 l in particular, the front frame 730 can be connected to | one side of the tubes 710, and the rear frame 740 can be connected to the other side. In this position, the front frame 730 and the rear frame 740 may have inlets 732 and outlets (not shown) corresponding to the shapes of both sides of the tubes 710. The inlets 732 and the outlets can be shaped to correspond to the range of the forearm 710 and the number of pipe stacks, and thus both ends of the pipes 710 having the heat sinks 720 therebetween can be inserted into the inlet 732 and into the outlet to fit therein. In addition, although both ends of the tubes 710 are inserted into the inlet 732 and the outlet, respectively, the spacers 716 support the upper surfaces 712 and the lower surfaces 714 of the tubes 710 to prevent deformation of the shapes of both ends of the tubes 710.
    Further, while the two ends of the tubes 710 are inserted into the inlets 732 and the outlets, respectively, when the upper and lower surfaces 712 and 714 of the tubes 710 are pressed by the heat sinks 720, the spacers 716 maintain an interval between the upper and lower surfaces 712 and 714 uniformly. so that the tubes 710 can be more easily adhered to | heat sinks 720.
    Such effects generated by the spacers 716 can further be more efficiently achieved when the support members 717 support the spacers 716.
    Moist air generated in a drying process in various environments not limited to any particular case is passed through the inlets 732 into the flow passage 719 of the tube 710 and then discharged through the outlets.
    At the same time, dry air is introduced from the environment and moves through the cooling flow passages 722 formed at the cooling flanges 720.
    Moist air and dry air are therefore introduced from the environment and do not mix with each other and move across each other to indirectly exchange heat with each other.
    Since the moist air which is led into the tube 710 after the drying process is hot and the dry air which is led into the cooling fins 720 is relatively cold, the moist air 533 958 vi can be condensed by heat exchange with the dry air so that the moisture is removed, and thus emitted as dry air.
    Figs. 14A-14E successively show a method of manufacturing a tube for the heat exchanger in accordance with a fifth embodiment of the present invention.
    As shown in Figs. 14A-14E, the method of manufacturing a tube 710 will be described below.
    First, both ends of a plate P are bent in a direction of the same length to form coupling parts. Here, the coupling parts can be provided as spacers 716.
    The plate P can be formed of different materials, preferably aluminum.
    In addition, an upper surface 712 may be formed by bending both sides of the plate P so that the spacers 716 are included therein.
    Furthermore, side surfaces 713 can be formed by bending both sides of the plate P so that the spacers 716 and the upper surface 712 are included therein.
    When the side surfaces 713 are formed by the bending, the spacers 716 can be adhered to each other, and the ends of the spacer 716 can be adhered to the lower surface 714 upon completion of the adhesion between the spacers 716.
    In addition, the heat sinks (see 720 in Fig. 12) and the tubes 710 are stacked sequentially outside the tubes 710, and the front and rear frames (see 730 and 740 in Fig. 12) are connected to both sides of the tubes 710 to fix the tubes 710. and the heat sinks 720, which completes the heat exchanger.
    Before the spacer part 716 is bent, both ends of the plate P can be bent in a direction of the same length to previously form the support parts 717.
    After the spacers 716 have been bent, of course, the end of the spacers 716 can be bent to form the support member 717. 533 958 22 In this case, it is obvious that the previously bent spacers 716 must be bent with a length to which the lengths of the support members 717 are added.
    As a result of the shaping of the side surfaces 713 by the bending process, the spacers 716 are adhered to each other. When the adhesion between the spacers 716 is complete, when the ends of the spacers 716 are adhered to the lower surfaces 714, the support members 717 are also adhered to the lower surface 714.
    The support members 717 can be bent to form an angle of 90 ° with respect to the spacers 716, preferably an angle of 61 greater than 90 °.
    In addition, the spacers 716 may be bent to form a 90 ° angle with respect to the side surfaces 713, preferably an angle of 92 greater than 90 °.
    As a result, both ends of the tubes 710 in the inlets (see 732 in Fig. 12) and the outlets are press-fitted when the tubes 710 are connected to the front and rear frames. and the upper and lower surfaces of the tubes 710 are pressed by the heat sinks installed between the tubes 710 so that the spacers 716 that are bent more than 61 are more securely adhered to each other by their elasticity.
    Furthermore, close adhesion between the spacers 716 can effectively prevent deformation of the spacers 716 such as bending and penetration of condensation water generated at the heat sinks into the tube 710 through a space between the spacers 716.
    Therefore, since a separate adhesion process such as soldering can be omitted in forming the spacers 716, a manufacturing process can be further facilitated and productivity can be improved.
    In addition, the support members 717 also bend more than O 2, and the support members 717 are tightly adhered to the lower surface 714 by using the elasticity in the adhesion of the lower surface 714 to produce a large frictional force, which more effectively prevents movement of the spacers 716. 533 958 23 To prevent a decrease in mounting performance when mounting the front and rear frames to the tubes 710, 91 and 92 may be less than 10 ° but are not limited thereto and may be suitably adjusted depending on conditions such as the material of the tube 710. , thickness, etc.
    In addition, the manufacturing method of the tube 710 may further comprise forming position guides (not shown) projecting from both ends of the upper surface 713 and the lower surface 713 of the tube 710.
    The position guides (not shown) can be pressed before the plate P is bent.
    The heat exchanger comprising the above-mentioned embodiment can be used in various heat exchange apparatus such as a clothes dryer for drying clothes.
    The heat exchanger and the method of manufacturing the same in accordance with an embodiment of the present invention have the following advantages: First, since the coupling parts are tightly adhered by means of adhesive or solder, it is possible to prevent leakage to the environment of fluid flowing - nom flow passage.
    Second, the coupling members projecting toward the flow passage can induce a laminar flow of the fluid flowing through the flow passage, which improves the heat exchanger efficiency.
    Thirdly, the coupling parts which are bent and extend towards the flow passage, and the position guides are provided to simplify a manufacturing and assembly process in order to improve the simplicity of manufacture and assembly, and to prevent deformation due to external shocks by means of a structure that is bent in the direction of the flow passage.
    Fourth, the slopes are formed at corners of the tube and the heat sinks have different heights at a central portion and both sides thereof to increase an amount of fluid introduced through the heat transfer passages of the heat sinks, which significantly improves heat exchanger performance.
    Fifth, since the position guides are formed on both sides of the upper and lower surfaces of the pipe to define fixing positions for the heat sinks, the heat sinks can be arranged between said plurality of stacked pipes at predetermined intervals.
    Sixth, the provision of the position controls facilitates the determination of coupling positions and mounting of the heat sinks during manufacture to improve the productivity and reassembly of the heat exchanger after disassembly of a user, which improves the convenience of assembly.
    Seventh, the position guides protrude from both sides of the tube and substantially increase the strength of the tube which prevents the formation of wrinkles from both ends of the tube, which maintains the shape of the tube uniformly.
    Eighth, the spacers are formed integrally with the center portion of the tube in a longitudinal direction of the tube to support the upper and lower surfaces of the tube, which maintains a longitudinal cross-section of the tube uniformly to improve the quality of appearance.
    Ninth, the support members are formed at the ends of the spacers which are formed at the center portion of the tube to support the spacers which prevents the spacers from separating or sloping from the center portion of the tube.
    Tenth, the pipe can be provided by molding alone, without any separate coupling process such as soldering, adhesion, folding, etc., which simplifies the manufacturing process and thus improves productivity. Although examples of embodiments of the present invention have been shown for illustrative reasons, those skilled in the art will recognize that various modifications, additions, and substitutions are possible without departing from the scope and spirit of the present invention, which invention is defined in the appended claims.
