Preferably, the second housing can receive at least one heating module having at least one element capable of exchanging additional heat than the at least one heating module adapted to be inserted into the first housing.
    [0004] Preferably, the intermediate wall is off-center to be closer to one of said lateral sides of the heating compartment, the means for creating a pressure drop is integral with this lateral side.
    [0005] Preferably, the intermediate wall is off-center so as to be closer to the first lateral side, said means making it possible to create a pressure drop extending in contact with this first lateral side. In this way, the means for creating a pressure drop is substituted for an element capable of exchanging heat. In this way, the dissipation of heat is substantially homogeneous on both sides of the intermediate wall with fewer elements capable of exchanging heat to predict, an optimized size and optimized weight. The housing of the electric air flow heating device according to the invention may further comprise one or more of the following characteristics, alone or in combination, in relation to said intermediate wall: said at least one intermediate wall is arranged substantially parallel to said lateral sides of the heating compartment, and between said lateral sides extending in the general extension direction of the heating compartment; Said at least one intermediate wall extends in a direction of general extension between a first end and a second end; said at least one intermediate wall is substantially longitudinal; - The first housing is sized to receive a heating module having a heat generating element disposed between two elements 20 for exchanging heat; the second housing is sized to receive a heating module comprising two elements capable of producing heat and three elements able to exchange heat; said at least one intermediate wall comprises at least one orifice; Said at least one intermediate wall is punched; At least a portion of said at least one intermediate wall has the properties of an elastic return blade; the intermediate wall comprises at least one locking finger.

According to one possible characteristic, the heating compartment and the two connection interfaces are made of material so that the housing is formed of one and the same block. According to a possible characteristic, the second connection interface extends transversely to the heating compartment, at the longitudinal end opposite to the first connection interface. According to a possible characteristic, the connection interfaces are disposed respectively at opposite ends of the heating compartment, these opposite ends preferably being said first and said second end between which said heating compartment extends in the direction of general extension. According to a possible characteristic, said at least one means for creating a pressure drop extends over the entire length of a lateral side of the heating compartment, from one connection interface to the other.

    [0006] Finally, the invention relates to a ventilation, heating and / or air-conditioning installation of a motor vehicle comprising at least one such heating device. Other features and advantages of the present invention will become more apparent from the description and the drawings, of which: FIG. 1 is a perspective view, three quarter rear, of a first embodiment; an additional heating device adapted to be housed across an air flow duct of a heating-ventilation and air conditioning assembly, said device being shown here without 5 heating modules inside the heating compartment ; FIG. 2 is a side view of the device of FIG. 1, also shown without the heating modules; - Figure 3 is a view similar to that of Figure 2, the device being shown this time with said heating modules; FIG. 4 is a perspective view, three-quarter rear, of a second embodiment of an additional heating device capable of being housed across an air flow duct of a set of heating-ventilation and air conditioning, said device being shown here without heating modules inside the two-part heating compartment 15 of the device; - Figure 5 is a perspective view, three quarters rear, of a first portion of the heating compartment shown in Figure 4; and FIG. 6 is a side view of the device of FIG. 4, also shown without the heating modules.
    [0007] In the description which follows, reference will be made to an orientation function of the Longitudinal, Vertical and Transversal axes as arbitrarily defined by the trihedron L, V, T represented in FIGS. 1 and 2. The choice of the 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. Referring to Figures 1 to 6 to describe the additional heating device according to two embodiments of the invention, the device being adapted to be housed across an air duct of an installation of 3032386 11 ventilation, heating and / or air conditioning, so as to convert the electrical energy taken from the vehicle into heat energy returned to the air passing through said ventilation, heating and / or air conditioning system. The installation is not shown here, but it will be understood that a main duct 5 of this installation conventionally comprises an opening made in the wall for the insertion of the additional heating device. A first embodiment is illustrated in FIGS. 1 to 3. An additional heating device 2 comprises a housing 3 and heating modules 4 (visible in FIGS. 3 and 4) capable of transforming an electric current into thermal energy. We can refer to the patent document FR2895204 for the more detailed description of the heating modules and an embodiment with the presence of heat sinks enclosed by electrodes on either side of one or more stones with positive temperature coefficient (effect CTP). The housing 3 comprises a heating compartment 6 for receiving the heating modules 4, a first connection interface 8 disposed at a proximal end 10 of the heating compartment 6 for connecting the device to an electrical network of the vehicle and feeding the heating modules 4, a second connection interface 12, in particular mechanical fixing, which is disposed at the distal end 14 of the heating compartment 6 opposite the proximal end 10 carrying the first connection interface 8 and which is suitable for cooperate with a duct wall of the ventilation system, heating and / or air conditioning, and a bar 16 which extends along the heating compartment 6 between the two connection interfaces 8, 12. It is considered that the heating compartment 6 and the two connection interfaces 8, 25 12 are monoblock when their separation causes destruction of the heating compartment 6 or one and / or the other interfaces 8, 12. It is observed that in this embodiment where the housing 3 is made in one piece, the bar 16 is made of the same material as the heating compartment 6 and that the connection interfaces 8, 12. It is then sought to favor the use of a material both lightweight and resistant. In this case, the casing 3 is advantageously made of a plastic material, for example polypropylene or polyamide, filled with glass fibers which, if necessary, makes mechanical stiffening possible. The heating compartment 6 has a rectangular parallelepiped shape whose two main faces are perforated transversely to allow the diffusion in the duct of the heat released by the heating modules 4 housed inside the heating compartment 6. Amounts 18 , arranged at intervals, regular or otherwise, from each other, extend vertically over the entire height of these main faces to stiffen the assembly without penalizing the release of heat.
    [0008] The heating compartment 6 comprises in addition to these uprights 18, three longitudinal walls, parallel to each other and among which are distinguished two side walls 20, 22 and an intermediate wall 24 disposed between these side walls 20, 22. The uprights 18 extend perpendicularly the two sidewalls 20, 22 from a respective transverse edge for connecting the sidewalls 20, 22 therebetween. In the illustrated example, it is possible to distinguish an upper side wall 20 and a lower side wall 22, the so-called upper side wall 20 being the supporting side wall of the bar 16, and the intermediate wall 24 is off-center in the vertical direction. so that it is closer to the so-called upper side wall 20. Two separate housings are thus defined in the heating compartment 6. A first housing 26 is defined by the so-called upper lateral wall 20, the uprights 18 and the wall intermediate 24, while a second housing 28 is defined by the so-called lower side wall 22, the uprights 8 and the intermediate wall 24.
    [0009] As a result, as shown in the figures, the first housing 26 has a height, in the vertical direction as defined by the illustrated trihedron, smaller than that of the second housing 28. The first housing 26 is dimensioned to receive a heating module 30 having two heat exchange elements such as heat sinks 29, while the second housing 28 is sized to receive a heating module 32 having three heat sinks 29. The heat sinks 29 are thus reported in the heating compartment 6, stacked on the others, with interposed PTC stones, to form an assembly of heating modules 30, 32 in which one of the heating modules has a heat sink of less than than the second heating module. Here a first heating module 30 has two heat sinks 29 while a second heating module 32 has three.
    [0010] As can be seen in the figures, the bar 16 is made integral with the side wall, here upper, corresponding to the housing 26 of the first heating module 30 which has a smaller number of heat sinks 29. This bar 16 thus comes replacing the missing heat sink with respect to the second heating module 32 having a greater number of heat sinks 29. The bar 16, as has been mentioned before, is advantageously grooved. In particular, the bar 16 may have a series of vertical grooves 33, regularly spaced apart from one longitudinal end of the bar 16 to the other, and perpendicular to the upper side wall 20. The width of the grooves 33 is provided to allow passage to the flow of air flowing in the duct, the air passing near the bar 16 or between the grooves 33 being heated by the pressure drop generated by the bar 16. The bar 16 extends longitudinally of a connection interface 8, 12 to the other, in vertical extension of the outer face 21, that is to say the face turned towards the outside of the heating compartment 6, of the so-called upper lateral wall 20, and substantially in the center thereof in the illustrated embodiment. The bar 16 has a small thickness relative to the transverse dimension of the side wall. It will be understood that the bar 16 could, without departing from the context of the invention, be offset transversely with respect to the center of the upper side wall 20.
    [0011] The intermediate wall 24 has guide flanges 34 which extend in vertical projection, partially along the intermediate wall 24, on each transverse side thereof, to facilitate the translational guidance of the heating modules 4 in the housings 26, 28 defined in the heating compartment 6, 5 during the sliding insertion thereof. It is understood that the side walls 20, 22 advantageously comprise equivalent guide edges. The intermediate wall 24 further comprises an elastically deformable blade 36, made in particular by partial punching of a portion of the wall 24, so that it is articulated to the intermediate wall 24 at a first longitudinal end and that it has opposite a free end which extends, in the rest position of the blade 36, projecting from the plane defined by the intermediate wall 24, in the second housing 28. The blade 36 is shaped so that this free end is spring-loaded in this position projecting into the second housing 28. In addition, it is visible in Figure 1 that the free end 15 has a boss 38 projecting from the plane of the blade 36 in the direction of the approximation of the plane of the intermediate wall 24, so that when the blade 36 is constrained to be in the plane defined by the intermediate wall 24, the boss 38 is located in the first housing 26. It is makes the side walls 20 and 22 may comprise an elastic deformation blade which extends into one or the other of the housing 26, 28 to perform the same function of holding the heating modules 4 in the housing. Moreover, snap-fastening fingers 40, with elastic deformation, are produced at the distal ends 42, that is to say the ends turned towards the second connection interface 12, the side walls 20, 22 and the wall 25. intermediate 24. Each latching finger 40 is made to extend in vertical projection of the wall that extends, in the direction of approximation of the side wall or intermediate neighbor. The detent finger 40 has an outer face 44, facing the second connection interface 12, which is inclined with respect to the vertical and an inner face, turned towards the inside of the heating compartment 6, which is substantially straight. to form a relief stop for the heating modules 4 when they are inserted in the heating compartment 6 of the device 2. It is understood that such shapes of the fingers 40 facilitate the spacing of the fingers 40 during the passage of the heating modules 4 towards the inside of the heating compartment 6 and that they block these heating modules 4 inside thereof when in position.
    [0012] As described above, the heating compartment 6 is integral with the first connection interface 8, which has a dual function, namely an electrical connection function to allow the connection of the heating modules 4 to a electric power source and a mechanical function for sealing the opening of the duct of the ventilation, heating and / or air conditioning system by which the heater 2 is inserted. The first connection interface 8 comprises a first substantially flat plate 46, which extends perpendicularly to the walls 20, 22, 24 of the heating compartment 6, and a sleeve 48 which extends longitudinally in projection from the first plate 46, opposite the heating compartment 6. The mechanical fastening means associated with the first connection interface 8 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, not shown here, integral with the duct of the ventilation system, heating and / or air conditioning, for the mechanical fixing of the additional heating device 2 relative to the duct. Furthermore, the first plate 46 has on its inner face 56, facing the heating compartment 6, a peripheral groove 58 (visible in FIG. 2) in which a seal can be positioned so as to ensure the seal against air between the inside of the air conditioning installation where extends the heating compartment 6 of the device 2 and the outside of this location where extends the first plate 46 and in particular the sleeve 48. In order to make the connection the electrodes associated with the heating modules to a source electrical network of the vehicle, provision is made according to the illustrated embodiment to equip the first interface 8 with slots 60 which extend from the inner face 56 of the first plate 46 , turned towards the heating compartment 6, to the outer face 62 carrying the sheath 48. The slots 60 open into the sleeve 48, and they are able to allow the reception in c sheath 48 of electrical connection means directly 5 connected to the vehicle network. These connection means cooperate with electrical connection terminals 64 made integral with electrodes 66 of the heating modules 4 (visible in FIG. 3), and the slots 60 extend longitudinally and have a defined section for receiving and guiding through the first interface 8 these electrical connection terminals 64, so that they can on the one hand be integral with the electrodes 66 inside the heating compartment 6 and they can also extend into the sheath protruding 48 from the outer face 62 of the first plate 46. The second interface 12 comprises a second plate 68 which extends transversely to the longitudinal walls 20, 22, 24 of the heating compartment 6, and substantially parallel to the first plate 46 of the first connection interface 8, and it further comprises a guide tab 70 disposed at a vertical end of the second plate 68. The second platinum 68 has a solid portion 72 opposite the guide tab 70, for the support of the grooved bar 16, and it has a central portion 20 having an opening 74 giving access to the two housing 26, 28 to the interior of the heating compartment 6. The opening made in the second plate 72 has a height, in the vertical direction, and a width, in the transverse direction, at least equal to the corresponding height and width of the recesses 26, 28 to allow insertion of the heating modules 4 in the heating compartment 6 through this opening, opposite to the first connection interface 8. The guide lug 70 carries complementary guide means of a second guide means secured to the leads. These guide means are arranged projecting from the heating compartment 6, in lateral clearance of the additional heating device 2. The second guide means integral with the conduit is a male or female element of complementary shape to a female element or male in the guiding means carried by the guide lug 70 of the second interface 12. In the example illustrated, the guiding means carried by the second interface 12 consist of a gripper 76 of internal diameter substantially equal to the external diameter d a guide rail (not visible in the figures) secured to the duct and extending along the location that must take the additional heating device 2 in the duct. A second embodiment illustrated in FIGS. 4 to 6 will now be described. It differs from the first embodiment described above in that the housing 103 is no longer made in one and the same part integrating the compartment 10 of 6 and the connection interfaces 8, 12. In order to facilitate the reading, reference will be made thereafter equivalent to those used for the description of the first embodiment when the parts have the same use, by adding 100. Here , the heating compartment 6 is made in two parts 106 and 107, each being secured to one of the connection interfaces 108 and 112, 15 and the bar 116 is fixed on the interfaces 108, 112 and on the parts of the compartment. heating 6 independently, by means of fixing means such as fixing lugs 78 and fixing studs 80. The material used to make the bar can thus be different of those used to make one and / or the other of the heating compartment parts and connection interfaces. For example, the bar 116, and the two parts 106, 107 of the heating compartment (and the corresponding connection interfaces) can be made all plastic, but with different materials. The first connection interface 108 and the first part 106 of the heating compartment can thus be made of a thermoplastic such as polybutylene terephthalate (PBT), the second connection interface 112 and the second part 107 of the heating compartment, brought to be accommodated in the duct of the ventilation, heating and / or air conditioning system may advantageously be made of polyamide (PA), while the bar 116 is advantageously made of polypropylene (PP), easily recyclable and sufficiently rigid to ensure holding function of the entire bar 116.
    [0013] It is understood that without departing from the context of this embodiment, the bar 116 could be integral with one of the parts of the heating compartment 106, 107 and / or one of the interfaces 108, 112, it would result of this variant that again materials different from those used for the rest of the housing 3 can be used for the embodiment of the bar 116 and at least a portion of the heating compartment 106, 107 and at least one connection interface 108, 112. In this second embodiment, a strip 116 is described which is produced independently and subsequently secured to one and the other of the parts of the heating compartment 106 and 107.
    [0014] Each part of the heating compartment 106 and 107 has three longitudinally extending walls parallel to each other, and of which two side walls 120, 122 and an intermediate wall 124 are arranged between these side walls 120, 122. In the illustrated embodiment, one can distinguish a so-called upper side wall 120 and a so-called lower side wall 122, the so-called upper side wall being the supporting side wall of the bar 116 on its outer face 121, that is to say its face turned away from the heating compartment 6. The lower side wall 122 has on its outer face, facing away from the heating compartment 6, a longitudinal groove stiffening 82, which extends over the entire length of the wall 122 and which is connected to the connection interface. At a proximal longitudinal end 84 of these walls 120, 122, 124 the corresponding connection interface forms a solid face, while at the opposite distal longitudinal end 86, the face has an open shape defined by a frame formed by two vertical uprights 88 extending over the entire height of the heating compartment 6, from one side wall 120, 122 to the other, an upper bar 90 extending at the distal longitudinal end of the upper side wall 120 and a lower bar 92 extending at the distal longitudinal end of the lower side wall 122. The upper bar 90 of the frame carries means for attaching the bar 116.
    [0015] It will be understood that for each part of the heating compartment 106 and 107, the solid face formed by the connection interface 108 and 112 is a stop face for the placement of the heating modules 4, 30, 32 in the housing. heating compartment 6, these heating modules 4, 30, 32 being inserted, at the opposite distal longitudinal end, by an insertion face delimited by the frame. The connection interfaces 108 and 112 and the upper side wall 120 of each heating compartment portion 6 may carry means for fixing the bar 116. In FIG. 4, the cooperation of the bar 116 with these FIGS. fixing means, while Figure 5 makes more visible the realization of said fixing means. The fixing means comprise a pair of lugs 78 arranged in vertical projection of the upper bar 90 of the frame at the distal longitudinal end 86 of the first part of the heating compartment 106, as well as four fixing studs 80, each forming a right angle, arranged in longitudinal projection of the internal face 156 of the first plate 146. The four fixing studs 80 are arranged relative to each other so that one end of the bar 116 comes to accommodate between these pads 80 (as shown in Figure 4). We can provide a welding operation of the bar 116 against the first interface 108 when the bar 116 is correctly held in position by the fixing studs 80, or it may be provided to adjust the initial position of the fixing studs 80 so that the mounting of the bar 116 is done by press fitting. The fixing lugs 78 each comprise a base 94 extending the upper bar 90 of the frame, these bases 94 being spaced apart from one another transversely to define an adjusted housing for the bar 116, and they each further comprise a retaining finger 96 which overhangs the base 94 and the fitted housing for the bar 116, and which tends to approach the other finger to create a decrease in the passage section between the lugs 78. The bar 116 is pushed vertically by force to spread the fingers 96 before taking up position in the housing, and the fingers 96 return to their original position by engaging in one of the grooves 133 of the bar 116, thus immobilizing the bar 116 vertically. The bar 116 can be welded to the connection interface after placement in the fastening means as just described.
    [0016] The foregoing description clearly explains how the invention achieves the objectives it has set for itself, through two particular embodiments.
