    [0001] The invention relates to the field of ventilation, heating and / or air conditioning of a motor vehicle. It relates to additional heating devices intended to be mounted in a ventilation system, heating and / or air conditioning of a motor vehicle. More particularly, the invention relates to an additional heating device comprising heating elements with electrical resistances, for example positive temperature coefficient (PTC) resistors, which make it possible to produce heat rapidly in the vehicles, especially when wants to quickly warm up the cabin. Heating devices of this type comprise a heating body comprising heat-exchanging heat exchange elements associated with said heating elements. These additional heating devices also comprise connection means that allow the electrical connection of the resistors to a source electrical network on board the vehicle, for the power supply of the heating elements, and connection means that allow the mechanical fixing of the device. additional heating to the ventilation, heating and / or air conditioning system. In this context, the invention aims to provide an alternative to known embodiments of additional heating devices, which is at least as effective, for less cost and simplified assembly. The invention relates to a housing of an additional electric type heating device for heating an air flow passing through a ventilation system, heating and / or air conditioning of a motor vehicle, the housing is able to carry to least one heating module, said housing comprising a heating compartment in which at least one heating module can be inserted and a first connection interface which allows the connection of the at least one heating module to a power supply of the vehicle. According to the invention, the heating compartment is formed of at least two distinct parts which define at least one housing in which said at least one heating module can be inserted, a first part of the heating compartment then being connected to the first interface connection, and in that the housing further comprises at least one bar attached to each of the parts of the heating compartment. The bar has the effect of stiffening the entire heating compartment formed in two parts, and to ensure the desired longitudinal separation between these two parts. It is understood that such a design has an advantage of modularity at lower cost, since it is possible to realize heating compartments 10 of different lengths with parts of heating compartment, more complex to achieve, which can remain the same, and a bar, simple to make, whose length is adapted to ensure the desired spacing. For this purpose, it may be interesting in a complementary feature that the bar is also reported on the first connection interface.
    [0002] According to a possible characteristic, each part of the heating compartment comprises at least one insertion side of the at least one heating module, this at least insertion side having at least one opening, the first part of the heating compartment and the second part of the heating compartment are arranged so that said sides are facing each other.
    [0003] Preferably, the insertion sides extend to the distal longitudinal end of each of the parts. According to a possible characteristic, the heating compartment is made of several different materials, the bar being able to be made of a material different from the material in which one and / or the other parts of the heating compartment are made. This optimizes the cost and weight of the heating device as a whole, by adapting the materials used to the functionality of the parts of the device. Thus, it can be expected that at least two of the two parts of the heating compartment and the bar are made of different materials, or that the bar is made of material with at least one of the parts of the heating compartment and / or the first connection interface. According to one possible feature, the bar has orifices. This avoids disturbances of the air flow in the duct through which the heating device is housed, and optimizes the pressure drop of the bar and the heating of the air passing in particular in these orifices, which preferably extend perpendicularly to the first side wall. It can be provided that these orifices take the form of grooves. The housing of the electric airflow heating device according to the invention may further comprise one or more of the following characteristics, alone or in combination: the at least one heating module extends, when it is disposed in the heating compartment in a direction of general extension between a first end and a second end; The general direction of extension of said at least one heating module is substantially longitudinal; the heating compartment extends in a direction of general extension between a first and a second end; the general extension direction of the heating compartment is substantially longitudinal; - At least a portion of at least one side of the heating compartment is recessed or openwork; the at least one heating module comprises at least one element capable of producing heat and at least one associated element capable of exchanging heat with the flow of air passing through the heating block; the at least one heating module is capable of producing and diffusing heat under the effect of an electric potential; Said at least one element capable of producing heat is a resistive element; said at least one element capable of producing heat is a positive temperature coefficient (PTC) type resistive element; said at least one heat generating element is a positive temperature coefficient (PTC) type resistive element disposed in or on a support such as a bar; said at least one element capable of producing heat is a resistive element placed between two electrodes; said at least one associated element which is capable of exchanging heat is a radiant element or a heat sink; said at least one heat-exchanging associated element is at least one fin traversed by at least one element capable of producing heat, or interleaves such as pleated or corrugated metal ribbons arranged between elements capable of producing heat ; Said at least one heat generating element is disposed between two heat exchangeable members; the at least one heating module comprises an element capable of producing heat disposed between two elements capable of exchanging heat; the at least one heating module comprises two elements capable of producing heat and three elements capable of exchanging heat, a heat exchangeable element being disposed between two elements capable of producing heat, each of these elements being able to produce heat; heat generating elements being disposed between the central heat exchangeable element and an external heat exchangeable element; The first connection interface extends transversely to the heating compartment.
    [0004] According to various features of the invention, taken alone or in combination: at least the first part of the heating compartment comprises side walls, substantially perpendicular to a first plate of the first connection interface, as well as an intermediate wall; , substantially parallel to the side walls and disposed inside the heating compartment between said side walls, the heating compartment defining two separate housings for one or more heating modules, between a first side wall, the first connection interface and the wall intermediate on the one hand 10 and between a second side wall, the first connection interface and said intermediate wall on the other hand, said at least one bar being integral with one of the side walls; the intermediate wall is off-center so that it is closer to the first side wall and a first housing defined between the first side wall, the first connection interface and the intermediate wall has a height between the intermediate wall and the first side wall less than the height between the second side wall and the intermediate wall of a second housing defined between the second side wall, the first connecting interface and said intermediate wall, and the bar is integral with the first side wall; At least the first connection interface and / or one of the side walls of the first portion of the heating compartment carries means for fixing the bar; said fixing means comprise at least one pair of lugs arranged in vertical projection of a frame of the insertion face of the heating module disposed at the distal longitudinal end of the first part of the heating compartment; said fixing means comprise at least two fixing studs arranged in longitudinal projection of the internal face of the first plate of the first connection interface.
    [0005] According to a characteristic of the invention, the housing may comprise a second connection interface, directly connected to the second part of the heating compartment, at a longitudinal end of the housing opposite to the end at which the first interface of the housing is arranged. connection.
    [0006] According to a possible characteristic, the second connection interface comprises a second plate formed of a solid wall arranged transversely to the second part of the heating compartment, said solid wall carrying indexing means for positioning the housing in position. duct of ventilation, heating and / or air conditioning.
    [0007] According to a possible characteristic, the strip is then advantageously also reported on the second connection interface. According to a possible characteristic, the second connection interface and one of the side walls of the second part of the heating compartment carries means for fixing the bar.

According to a possible characteristic, said fixing means comprise at least two fixing studs arranged in longitudinal projection of the internal face of the second plate of the first connection interface. The invention also relates to a heating device which comprises a housing as described above and at least one heating module housed in the heating compartment of the housing, and a ventilation, heating and / or air conditioning installation of a motor vehicle comprising such a heater. Other features and advantages of the present invention will become more clearly apparent from the description and the drawings, of which: FIG. 1 is a perspective view, three quarter rear, of an additional heating device capable of to be housed across an air flow duct of a ventilation assembly, heating and / or air conditioning, said device being shown here without associated heating modules; FIG. 2 is a side view of the additional heating device of FIG. 1, in which the heating modules are shown diagrammatically; - Figure 3 is a perspective view, three quarters rear, of a first portion of the additional heating device illustrated in Figure 1; And FIG. 4 is a perspective view, three quarters before this time, of a second part of the additional heating device illustrated in FIG. 1. In the description which follows, reference will be made to a function which is a function of Longitudinal, Vertical and Transversal axes as arbitrarily defined by the L, V, T trihedron shown in the figures. The choice of designations of these axes is not limiting of the orientation that can take the device in its application to a motor vehicle, and the use of terms such as "superior" and "lower" is chosen according to the orientation in the illustration accompanying this description without it being either limiting.
    [0009] 1 to 4 to describe an additional electrical heating device capable of being housed across an air flow duct of a ventilation, heating and / or air conditioning installation, so as to transform the electrical energy taken from the vehicle in thermal energy returned to the air passing through said ventilation, heating and / or air conditioning system. The heating-ventilation and air conditioning installation is not shown here, but it will be understood that a main duct of this installation conventionally comprises an opening made in the wall for the insertion of the additional heating device.
    [0010] The additional heating device according to the invention comprises a housing and heating modules 4 (visible in FIG. 2) capable of transforming an electric current into thermal energy. Reference may be made to patent document FR2895204 for the more detailed description of the heating modules and an example embodiment with the presence of heat sinks sandwiched by electrodes on either side of one or more stones with a positive temperature coefficient ( CTP effect). According to the invention, the housing of the additional heating device 2 is formed by a heating compartment allowing the reception of the heating modules 4 10 formed in two parts 6 and 8, a first connection interface 10, for connecting the device to a vehicle electrical network and the supply of the heating modules 4, which carries a first portion 6 of the heating compartment, a second interface 12, in particular mechanical fixing, which is adapted to cooperate with a wall of the duct of the ventilation system , heating and / or air conditioning, and which carries a second portion 8 of the heating compartment, and a bar 14 which extends longitudinally between the two connection interfaces 10, 12. Each part 6 and 8 of the heating compartment has substantially the same rectangular parallelepiped shape whose two main faces are perforated to allow diffusion in the duct heat released By the heating modules 4 whose one end is accommodated within a part of the heating compartment. The connection interfaces 10 and 12 each carry a part of the heating compartment so that the positioning of the interfaces 10, 12 facing each other makes it possible to form a complete heating compartment for receiving the heating modules 4. Advantageously, the parts of the heating compartment 6 and 8 are integral with the corresponding connection interface 10 and 12, even if it is conceivable without departing from the context of the invention that one and / or the other these parts of the heating compartment are made separately interfaces 10, 12 corresponding and reported and fixed, particularly by welding, on the interfaces 10, 12.
    [0011] Each part of the heating compartment 6 and 8 has three walls extending longitudinally, parallel to each other, and among which there are two side walls 16, 18 and an intermediate wall 20 disposed between these side walls. It is possible to distinguish a first, so-called upper, lateral wall 16 and a second, so-called lower, lateral wall 18, the first so-called upper lateral wall 16 being the supporting lateral wall of the bar 14, which extends in a vertical extension of its outer face 21, that is to say the side facing the outside of the heating compartment, and substantially in the center thereof. The second lower side wall 18 has on its outer face, facing away from the heating compartment, a longitudinal stiffening groove 22, which extends over the entire length of the wall and is connected to the interface connection. At a proximal longitudinal end 24 (referenced in FIG. 2) of these walls, the corresponding connection interface 10 and 12 form a solid face, while at the opposite distal longitudinal end 26, the face has an open shape. defined by a frame formed by two vertical uprights 28 which extend over the entire height of the heating compartment, from one side wall to the other, an upper bar 30 extending to the distal longitudinal end of the side wall 16 and a lower bar 32 extending at the distal longitudinal end of the lower side wall 18. The top bar 30 of the frame carries means for fixing the bar 14. It is understood that for each part of the compartment 6 and 8, the solid face formed by the connection interface 10 and 12 is a stop face for the placement of the heating modules 4 in the heating compartment, these modules 4 being inserted, at the opposite distal longitudinal end, by an insertion face delimited by the frame. In the illustrated embodiment, in each part of the heating compartment, the intermediate wall 20 is off-center in the vertical direction so that it is closer to the first so-called upper side wall 16. Two separate housings are thus defined in each part of the heating compartment. A first housing 34 is defined by the first said upper side wall 16, the connection interface 10 or 12 and the intermediate wall 20, while a second housing 36 is defined by the second said lower side wall 18, the connection interface 10 or 12 and the intermediate wall 20. As a result, as seen in each of the figures, the first housing 34 has dimensions smaller than those of the second housing 36. The first housing 34 is dimensioned to receive a first heating module 38 having two heat sinks, while the second housing 36 is sized to receive a second heating module 40 carrying three heat sinks. The heating modules are thus reported in each part of the heating compartment, one stacked on the other, so as to form several distinct groups of the heating modules, a first heating module having a heat sink of less than the second heating module. Here a first heating module 38 has two heat sinks while a second heating module 40 has three.
    [0012] Each of the longitudinal walls has guide flanges 42 (visible in FIG. 3) which project vertically, partially along the corresponding wall, on each transverse side thereof, to facilitate the translational guiding of the longitudinal walls. heating modules in the housings defined in the parts of the heating compartment.
    [0013] As just described, it is observed that the bar 14 is secured to the first upper side wall 16, corresponding to the housing of the first heating module having fewer heat sinks. This bar 14 is thus substituted for the missing heat sink relative to the heating module having a greater number of heat sinks. In this way, the heat dissipation is substantially homogeneous on both sides of the intermediate wall 20. The bar 14, as has been mentioned before, has orifices and is advantageously grooved. In particular, the bar 14 may have a series of vertical grooves 44, regularly spaced from each other since a longitudinal end of the bar 14 to the other, and perpendicular to the upper side wall 16. The bar 14 extends longitudinally of a connection interface 10 to the other 12, in vertical extension of the upper side walls 16 of each part of the heating compartment 6 and 8, and substantially in the center of these side walls 16, 18. The bar 14 presents a small thickness relative to the transverse dimension of the side wall. It is understood that the strip 14 here plays a dual role of heat dissipation and optimization of the heating performance of the device on the one hand, and mechanical strength of the entire additional heating device 10 on the other hand . The strip 14 is attached for this purpose on each upper side wall 16 and on each connection interface 10 or 12, and it will be understood that the strip 14 may be made independently and then welded or glued for example to these elements of the heating device. 2, or it may be integral with one or the other of the connection interfaces 10, 12 and parts of the corresponding heating compartment. It will be understood that the advantage of making distinctly the pieces that are the bar 14 and the two parts 6, 8 of the heating compartment is to propose a greater modularity to adapt more easily to the demands of 20 motor vehicle manufacturers. It is possible to play on the length of the bar 14 and on the type of material used. The longitudinal dimension of the bar 14 can thus vary as a function of the desired space requirement of the heating device 2 and the longitudinal gap provided between the connection interfaces 10 and 12, it being understood that the ends 25 of the strips 14 advantageously remain contacting the connection interfaces 10, 12 to ensure greater rigidity of the assembly. The material used to make the strip 14 may thus be different from those used to make one and / or the other parts of the heating compartment and the connection interfaces 10, 12. For example, the strip 14 and both parts 6, 8 of the heating compartment (and the corresponding connection interfaces 3032390 12) can be made of all plastics, but with different materials. The first connection interface 10 and the first part 6 of the heating compartment can thus be made of a thermoplastic such as polybutylene terephthalate (PBT), the second connection interface 12 and the second part 8 of the heating compartment, brought to be housed in the duct of the ventilation system, heating and / or air conditioning may advantageously be made of polyamide (PA), while the bar 14 is advantageously made of polypropylene (PP), easily recyclable and rigid enough to provide the function holding the entire bar 14.
    [0014] In FIG. 3, a detail of the heating device according to the invention is illustrated with the first part 6 of the heating compartment and the corresponding first connection interface 10. The first connection interface 10 has a dual function, namely an electrical connection function to allow the connection of the heating modules to a source of electrical energy on board the vehicle and a mechanical function to seal the opening of the vehicle. duct of the ventilation, heating and / or air conditioning system by which the heater is inserted. The first connection interface 10 comprises a first plate 46 substantially flat, and a sleeve 48 which extends longitudinally projecting from the plate. The first plate 46 extends perpendicular to the longitudinal walls of the portion of the heating compartment that it supports, the longitudinal walls extending an inner face of the plate 46 while the sleeve 48 extends from the outer face of the plate 46 opposite the heating compartment of the additional heating device. The mechanical fixing means associated with the first connection interface 10 are carried by the first plate 46 which has at its vertical ends 50 fixing lugs 52 in which fixing holes 54 allow the cooperation of screwing means with threaded means. , here not shown, integral with the duct of the ventilation system, heating and / or air conditioning for the mechanical fixing of the additional heating device 2 with respect to this duct. Furthermore, the first plate 46 has on its inner face 56, facing the heating compartment, a peripheral groove 58 (visible in FIG. 2) in which a seal can be positioned so as to seal against the air between the interior of the duct of the ventilation system, heating and / or air conditioning where extends the heating compartment of the device and the outside of this duct where extends the first plate 46 and in particular the sleeve 48. The first interface 10 has slots 60 which extend from the inner face 56 of the first plate 46 to the outer face 62 carrying the sleeve 48. The slots 60 open into the sleeve 48, the dimensions of which are suitable. to allow reception in this sleeve 48 of electrical connection means, not shown here, directly connected to the vehicle network. These connection means cooperate with the electrodes of the heating modules, it being understood that electrical connection terminals made integral with the electrodes can be provided to prolong them and allow the passage of the assembly through the slots 60 to access the means. electrical connection of the vehicle. These slots 60 extend longitudinally and have a section defined to receive and guide through the first interface 10 the electrodes and / or the connection terminals, so that they can extend into the sleeve 48 projecting from the external face of the first plate 46. The first interface 10 and the upper side wall of the first part 6 of the heating compartment carry means for fixing the bar 14. In Figure 1, we can see represented the cooperation of the bar 14 with these fixing means 25, while Figure 3 makes more visible the realization of said fastening means. The fixing means comprise a pair of lugs 64 arranged in vertical projection of the upper bar 30 of the frame at the distal longitudinal end 26 of the first part of the heating compartment 6, as well as four fixing studs 66, each forming a right angle, arranged in longitudinal projection of the inner face 56 of the first plate 46. The four fixing studs 66 are 3032390 14 arranged relative to each other so that one end of the bar 14 comes from lodge between these pads (as shown in Figure 1). It is possible to provide a welding operation of the bar 14 against the first interface 10 when the bar 14 is correctly held in position by the fixing studs 66, or it may be possible to adjust the initial position of the fixing studs 66 for that the mounting of the bar 14 is done by a press fit. The fixing lugs 64 each comprise a base 68 extending the upper bar 30 of the frame, these bases 68 being spaced apart from one another transversely to define an adjusted housing for the bar 14, 10 and they each further comprise a retaining finger 70 which overhangs the base 68 and the fitted housing for the bar 14, and which tends to approach the other finger to create a decrease in the passage section between the lugs 64. The bar 14 is pushed vertically by force to spread the fingers 70 before taking up position in the housing, and the fingers 70 return to their original position by engaging in one of the grooves 44 of the bar 14, thus vertically immobilizing the bar 14. In the figure 4, there is illustrated a detail of the device according to the invention, with the second part of the heating compartment 8 and the second connecting interface 12 corresponding. The second interface 12 comprises a second plate 72 which extends perpendicularly to the longitudinal walls of the part of the heating compartment that it supports, and substantially parallel to the first plate 46 of the first connection interface 10. In a manner similar to what could be described for the first connection interface 10 and the part of the associated heating compartment, fixing means of the bar 14 are provided both on the upper bar 30 of the frame at the distal longitudinal end the portion of the heating compartment that on the inner face of the second plate 72 of the second connection interface 12. The inner face 74 of the second plate 72, that is to say the face that carries the longitudinal walls of the second portion 8 of the heating compartment, has 3032390 abutment pads 76, in number equal to the number of heating modules present in the device cha The second plate 72 has a solid shape and has on its outer face 78 a rib 80 which extends vertically substantially in the center of the second plate 72. Furthermore, the second portion 8 of the heating compartment differs of the first part 6 previously described in that it comprises elastic return retaining tabs 82, carried by the vertical uprights 28 of the frame, and which extend towards the interior of the housings defined in this second part of the heating compartment 8 on either side of the intermediate wall 20. These tabs 82 allow the longitudinal retention of the heating modules 4 (as can be seen in FIG. 2), it being understood that the retention in the longitudinal position relative to the first interface 10 is done by inserting the electrodes into the slots 60 and their electrical connection, and maintaining the longitudinal position of the 1 and 12 connection interfaces between them is by the presence of the stiffening bar 14. The presence of the holding tabs 82 allows in particular to avoid that there are too many constraints on the bar 14 or on the electrical connection to the level of the first interface 10. The second plate 72 of the second connection interface 12 is extended at one of its vertical ends by means of guiding shapes complementary to those of a guide means integral with the conduit. In the illustrated example, the guiding means carried by the second interface 12 consist of a gripper 84 of internal diameter substantially equal to the external diameter of a guide rail (not visible in the figures) integral with the duct and extending along the location that must take the additional heater 2 in the conduit. We will now describe the mounting of the additional heating device 2, monobloc according to the invention. Each group of two or three heating modules 38, 40 is inserted into the appropriate housings inside the first part 30 of the heating compartment 6 and then into the appropriate housings inside the second part of the heating compartment. 6. It may be preferred to initially position the heating modules 4 in the second part of the heating compartment 8 so that they are held in position by the holding tabs carried by this second part of the heating compartment 8, it being understood that Mounting the heating modules 4 between these retaining tabs can generate stresses that could cause damage if the electrodes are engaged in the slots of the first interface 10 at this particular time. Thus, the heating modules 4 are first inserted by the insertion face at the distal end 26 of the second part of the heating compartment 8, by first inserting the side of the heating modules 4 opposite the carrier side. free ends of the electrodes, and the heating modules 4 are slid in translation until they abut against the second connection interface 12 and the abutment pads 76 carried by the second plate 72. The retaining tabs 82 are spaced from each other by the passage of the heating modules 15 4, and the elastic force of return in position of these retaining tabs 82 tends to grip and hold in position the heating modules 4 in the second part of the compartment 8. In the case where the bar 14 is made independently of the connection interfaces 10 and 12, then this bar 14 is mounted relative to one or other of the interfaces and the corresponding heating compartment part. In the example described, the bar 14 is mounted at one end against the second interface 12, by inserting one end of the bar 14 between the fixing studs 66 carried by the second plate 72, and by clipping an edge of the bar 14 in the attachment pins 64 carried by the frame.
    [0015] The heating modules 4 are then inserted through the insertion face at the distal end 26 of the first part of the heating compartment 6, the electrodes or the connection terminals first, and the heating modules 4 are slid in translation. to the first connection interface 10. The heating modules 4 are guided transversely by the presence of the guide flanges 42. In this translation of the two parts 6, 8 of the heating compartment towards one another, the slide bar 14 slides so that its free end moves towards the first plate 46 of the first interface 10, after having been slid into the housing defined between the fixing pins 64 carried by the frame of the insertion face of the first part 6 of the heating compartment 6. At the end of insertion, the free end of the electrodes or terminals 5 enters the slot 60 which is associated with it so as to emerge from the other side of the first connection interface 10, inside the sheath. And the free end of the bar 14 is engaged between the fixing studs 66 carried by the first plate 46. The additional heating device 2 is then inserted into a duct of the ventilation, heating and / or air conditioning system. , by initial insertion of the second connection interface 12 in an opening made in this conduit. The guiding means 84 carried by the second connection interface 12 are made to cooperate with complementary guiding means carried by the duct, in order to bring the second connection interface 12 and the first connection interface 10 respectively against mounted fixing means. by the conduit. The first connection interface 10 is secured to the conduit of the ventilation system, heating and / or air conditioning by screwing, while the second connection interface 12 is pressed against the wall of the conduit, locked in position by indexing lugs arranged projecting from this wall. It may be envisaged that the wall of the duct against which the second connection interface 12 is plated carries means complementary to the rib extending over the height of the external face of the second plate 72, to allow the heating device to be mounted. 2 in the conduit by interlocking with the force of the second connection interface 12. In all cases, it is notable that the second connection interface 12 allows on the one hand the holding of the heating modules 4 in the additional heating device 2 and secondly the positioning of the additional heating device 2 in the conduit of the installation. The terminals are then connected to the vehicle's electrical network. The control management of the additional heating device 2 is, in the illustrated case, located elsewhere on the vehicle, for example in an electronic cockpit computer 3032390. However, one could consider integrating a control module into the first connection interface 10. The above description clearly explains how the invention makes it possible to achieve the objectives that it has set itself and in particular to propose an assembly 5 heater in which an electric heater is arranged across a duct of a ventilation, heating and / or air-conditioning system of a motor vehicle, to allow heat diffusion by electrical excitation of the heated heating modules by or housed in a housing of an additional heating device. The fact that this housing is made in two separate parts, each secured to a connection interface allows a high modularity of realization of the entire housing, that is to say the heating compartment and the interface or interfaces connection, which can be made distinctly in one or another material, whether metal or plastic, loaded or not. It is thus possible to give each of the parts the rigidity and lightness appropriate to their function in the device. Moreover, it is easy, because of the modular design of the housing, to play on the length of the bar to adapt to the different demands of motor vehicle manufacturers as to the size of the additional heating device to provide. The connection interfaces may remain the same, and the bar is easily shortened or enlarged to accommodate the desired spacing between these interfaces.
