[2] L’invention concerne notamment des échangeurs thermiques à plaques destinés à la circulation d’un fluide frigorigène permettant le refroidissement des batteries de véhicules hybrides ou électriques.

Technique antérieure Prior art
[3] Pour améliorer la conduction thermique entre les éléments chauffants en fonctionnement et le dispositif de régulation thermique, de la pâte thermique est disposée entre eux. Lors de l’assemblage de ces éléments chauffants avec le dispositif de régulation thermique, il s’ensuit des efforts mécaniques en compression sur le dispositif de régulation thermique. Il est connu de compenser ces efforts par des tampons élastiques. Cependant, ces tampons élastiques présentent comme inconvénients d’être particulièrement onéreux en raison de leur production notamment en silicone. Le silicone étant choisi car il présente une résistance au feu acceptable pour les domaines d’application souhaités. D’autres matériaux sont connus de l’art tel que l’utilisation d’EPDM (éthylène-propylène-diène monomère) ou PU (polyuréthane) pour ces tampons élastiques. [3] To improve thermal conduction between the operating heating elements and the thermal regulation device, thermal paste is placed between them. When these heating elements are assembled with the thermal regulation device, mechanical compressive forces result on the thermal regulation device. It is known to compensate for these efforts with elastic buffers. However, these elastic tampons have the disadvantage of being particularly expensive due to their production in particular in silicone. Silicone being chosen because it has acceptable fire resistance for the desired areas of application. Other materials are known in the art such as the use of EPDM (ethylene-propylene-diene monomer) or PU (polyurethane) for these elastic pads.
[4] Il est également connu de fournir des plaques pour l’échangeur thermiques plus épaisses. Néanmoins, une telle solution présente l’inconvénient d’accroître la masse du véhicule, augmentant ainsi sa consommation énergétique. [4] It is also known to provide thicker plates for the heat exchanger. However, such a solution has the disadvantage of increasing the mass of the vehicle, thus increasing its energy consumption.

In addition, the invention makes it possible to minimize the mass contribution to the vehicle. The invention also has the advantage of offering a solution compatible with different types of thermal regulation devices or of being adapted to the needs of each of these thermal regulation devices.
[7] L’invention a également pour objet un module thermique comprenant un dispositif de régulation thermique, notamment de refroidissement, pour composant électrique susceptible de dégager de la chaleur lors de son fonctionnement, notamment pour un module de stockage d’énergie électrique, ce dispositif comportant une plaque supérieure et une plaque inférieure assemblée avec la plaque supérieure pour former ensemble une pluralité de canaux de circulation pour un fluide caloporteur, le module comprenant également au moins une plaque de renfort telle que décrite précédemment.

[8] According to one of the aspects of the invention, the reinforcing plate is configured to be in contact with a face of the lower plate opposite to a face of the lower plate in contact with the upper plate.
[9] Selon l’un des aspects de l’invention, la plaque de renfort comprend une première section configurée pour être en contact avec une portion de la plaque inférieure qui comprend au moins une portion de la pluralité de canaux de circulation. [9] According to one of the aspects of the invention, the reinforcing plate comprises a first section configured to be in contact with a portion of the lower plate which comprises at least one portion of the plurality of circulation channels.
[10] Selon l’un des aspects de l’invention, la plaque de renfort peut comprendre une seconde section configurée pour être en contact avec une portion de la plaque inférieure dépourvue de canaux de circulation. [10] According to one of the aspects of the invention, the reinforcing plate may comprise a second section configured to be in contact with a portion of the lower plate devoid of circulation channels.
[11] Selon l’un des aspects de l’invention, la plaque de renfort comprend au moins une nervure. [11] According to one of the aspects of the invention, the reinforcing plate comprises at least one rib.
[12] Selon l’un des aspects de l’invention, la nervure comprend une direction principale d’extension, ladite direction étant disposée dans un plan de la plaque de renfort et selon une direction sécante à l’orientation principale de la pluralité de canaux de circulation de la portion de la plaque inférieure sur laquelle est disposée la plaque de renfort, préférentiellement de façon perpendiculaire à l’orientation principale des canaux de circulation de la portion de la plaque inférieure sur laquelle est disposée la plaque de renfort. On comprend ainsi que ladite orientation principale des canaux est celle des canaux configurés pour être disposés en vis-à-vis de la première section de la plaque de renfort, ladite première section comprenant l’au moins une nervure. Par orientation principale de la pluralité de canaux, il faut comprendre l’orientation de la dimension la plus importante dans laquelle les canaux à considérer s’étendent. [12] According to one of the aspects of the invention, the rib comprises a main direction of extension, said direction being arranged in a plane of the reinforcing plate and in a direction secant to the main orientation of the plurality of circulation channels of the portion of the lower plate on which the reinforcing plate is placed, preferably perpendicular to the main orientation of the circulation channels of the portion of the lower plate on which the reinforcing plate is placed. It is thus understood that said main orientation of the channels is that of the channels configured to be arranged opposite the first section of the reinforcing plate, said first section comprising at least one rib. By main orientation of the plurality of channels, we must understand the orientation of the most important dimension in which the channels to be considered extend.
[13] Selon l’un des aspects de l’invention et de façon alternative, la nervure est disposée parallèlement à la pluralité de canaux de circulation de la portion de la plaque inférieure sur laquelle est disposée la plaque de renfort. [14] Selon l’un des aspects de l’invention, la plaque de renfort comprend une surface supérieure configurée pour être en contact avec F au moins une portion de la plaque inférieure, la nervure est formée par une cavité s’étendant depuis la surface supérieure de la plaque de renfort et perpendiculairement à la plaque inférieure du dispositif de régulation thermique. De façon avantageuse, la nervure peut être obtenue par emboutissage de la plaque de renfort, ainsi la plaque de renfort tout en conservant la robustesse procurée par la nervure permet d'optimiser la quantité de matière nécessaire à l’obtention de la pièce. [13] According to one of the aspects of the invention and alternatively, the rib is arranged parallel to the plurality of circulation channels of the portion of the lower plate on which the reinforcing plate is arranged. [14] According to one of the aspects of the invention, the reinforcing plate comprises an upper surface configured to be in contact with F at least a portion of the lower plate, the rib is formed by a cavity extending from the upper surface of the reinforcement plate and perpendicular to the lower plate of the thermal regulation device. Advantageously, the rib can be obtained by stamping the reinforcing plate, thus the reinforcing plate while retaining the robustness provided by the rib makes it possible to optimize the quantity of material necessary to obtain the part.
[15] Selon l’un des aspects de l’invention, la cavité peut comprendre un isolant thermique. [15] According to one of the aspects of the invention, the cavity can comprise a thermal insulator.
[16] On comprend également que la nervure peut être obtenue par extrusion ou moulage de la plaque de renfort. La nervure peut être venue de matière et dépourvue de cavité, c’est-à-dire que depuis une vue en coupe transversale de la plaque de renfort, la nervure serait pleine de matière. [16] It is also understood that the rib can be obtained by extrusion or molding of the reinforcing plate. The rib can be made of material and devoid of cavity, that is to say that from a cross-sectional view of the reinforcing plate, the rib would be full of material.
[17] Selon l’un des aspects de l’invention, la plaque de renfort comprend une pluralité de nervures telles que décrites précédemment. [17] According to one of the aspects of the invention, the reinforcing plate comprises a plurality of ribs as described previously.
[18] Selon l’un des aspects de l’invention, la pluralité de nervures comprend des nervures de dimensions différentes. [18] According to one of the aspects of the invention, the plurality of ribs comprises ribs of different dimensions.
[19] Selon l’un des aspects de l’invention, au moins une nervure de dimension distincte des autres nervures peut être disposée sur une périphérie de la plaque de renfort ou de façon alternative, l’au moins une nervure de dimension distincte peut être disposée au centre de la plaque de renfort. [19] According to one of the aspects of the invention, at least one rib of distinct dimension from the other ribs can be arranged on a periphery of the reinforcing plate or alternatively, the at least one rib of distinct dimension can be placed in the center of the reinforcement plate.
[20] Selon l’un des aspects de l’invention, la pluralité de nervures comprend un ensemble de tronçons rectilignes et parallèles entre eux. On comprend que ce sont ces tronçons rectilignes qui définissent l’orientation principale d’allongement des nervures. [20] According to one of the aspects of the invention, the plurality of ribs comprises a set of rectilinear sections parallel to each other. We understand that it is these rectilinear sections which define the main orientation of elongation of the ribs.
[21] Selon l’un des aspects de l’invention, la pluralité de nervures comprend des tronçons présentant une forme en U reliant des tronçons rectilignes voisins. [21] According to one of the aspects of the invention, the plurality of ribs comprises sections having a U shape connecting neighboring rectilinear sections.

[24] Selon l’un des aspects de l’invention, chacun des groupes de nervures est configuré pour être disposé sur des portions de la pluralité de canaux ayant une direction principale d’extension différente d’une autre portion. On comprend donc que les différents groupes de nervures présentent des directions principales d’extension différentes. [24] According to one of the aspects of the invention, each of the groups of ribs is configured to be arranged on portions of the plurality of channels having a main direction of extension different from another portion. We therefore understand that the different groups of ribs have different main directions of extension.
[25] Selon l’un des aspects de l’invention, un des groupes de nervures comprend au moins deux nervures, chacun d’elles étant disposée sur au moins un côté d’un autre groupe de nervure, lesdites nervures disposées sur les côtés peuvent avoir des dimensions différentes des nervures du groupe qu’elle jouxte, préférentiellement des dimensions plus importantes. Ceci permet d’adapter la rigidité de la plaque de renfort de façon optimale en fonction du dispositif de régulation thermique. [25] According to one of the aspects of the invention, one of the groups of ribs comprises at least two ribs, each of them being arranged on at least one side of another group of ribs, said ribs arranged on the sides may have different dimensions from the ribs of the group it adjoins, preferably larger dimensions. This makes it possible to adapt the rigidity of the reinforcing plate optimally depending on the thermal regulation device.
[26] Selon l’un des aspects de l’invention, la plaque de renfort comprend sur au moins une portion de son pourtour une paroi périphérique s’étendant principalement perpendiculairement aux plans d’allongement principal de la plaque supérieure et de la plaque inférieure. Ainsi, et de façon avantageuse, la paroi augmente davantage la résistance de la plaque de renfort, notamment pour des contraintes mécaniques de torsion et de flexion sur la plaque inférieure du dispositif de régulation thermique. [26] According to one of the aspects of the invention, the reinforcing plate comprises on at least a portion of its periphery a peripheral wall extending mainly perpendicular to the main elongation planes of the upper plate and the lower plate . Thus, and advantageously, the wall further increases the resistance of the reinforcing plate, in particular for mechanical stresses of torsion and bending on the lower plate of the thermal regulation device.
[27] Selon l’un des aspects de l’invention, la paroi est venue de matière avec la plaque de renfort, préférentiellement obtenue par emboutissage. [27] According to one of the aspects of the invention, the wall is made integrally with the reinforcing plate, preferably obtained by stamping.
[28] Selon l’un des aspects de l’invention, la plaque de renfort couvre 25% de préférence 50% encore préférentiellement la totalité de la surface de la plaque inférieure. [28] According to one of the aspects of the invention, the reinforcing plate covers 25%, preferably 50%, more preferably the entire surface of the lower plate.
[29] L’invention a également pour objet un dispositif de renfort comprenant une pluralité de plaques de renfort telles que la plaque de renfort précédemment décrite et configurées pour être fixées à une même plaque inférieure d’un dispositif de régulation thermique. [29] The invention also relates to a reinforcement device comprising a plurality of reinforcement plates such as the reinforcement plate previously described and configured to be fixed to the same lower plate of a thermal regulation device.

[32] Selon l’un des aspects de l’invention, la plaque de renfort a une forme préférentiellement similaire à la plaque inférieure mais de façon alternative elle peut être d’une autre forme que la plaque inférieure. On comprend ainsi que lorsque la plaque inférieure est de forme principalement plane, la plaque de renfort est préférentiellement plane. [32] According to one of the aspects of the invention, the reinforcing plate has a shape preferably similar to the lower plate but alternatively it can be of another shape than the lower plate. It is thus understood that when the lower plate is of mainly planar shape, the reinforcing plate is preferentially planar.

Ces matériaux métalliques ayant pour avantage de ne pas être inflammables, contrairement aux tampons élastiques de l’art antérieur. De plus, ils peuvent offrir une meilleure résistance à l’usure ainsi qu’une meilleure recyclabilité. [34] According to one of the aspects of the invention, the reinforcing plate is produced from metallic materials, preferably aluminum. These metallic materials have the advantage of not being flammable, unlike the elastic buffers of the prior art. In addition, they can offer better wear resistance as well as better recyclability.
[35] Selon l’un des aspects de l’invention et de façon alternative, la plaque de renfort peut être faite d’un matériau composite. Ceci aurait pour avantage de procurer une bonne résistance mécanique tout en alliant une plus grande légèreté par rapport aux matériaux métalliques, ce qui permet dans l’exemple d’une utilisation dans un véhicule de réduire la consommation en énergie pour sa propulsion. [35] According to one of the aspects of the invention and alternatively, the reinforcing plate can be made of a composite material.

Par orientation principale de la pluralité de canaux, il faut comprendre l’orientation de la dimension la plus importante dans laquelle les canaux 4 à considérer s’étendent. Ainsi dans les exemples des figures 1 et 2, les nervures 9 de la plaque de renfort 1 s’étendent perpendiculairement aux canaux 4 placés sous ces nervures 9. Dans les figures 1 et 2, les canaux 4 s’étendent principalement dans la longueur de la plaque inférieure 3 et donc les nervures 9 s’étendent principalement dans une direction disposée selon la largeur de la plaque inférieure 3. [69] De façon alternative, la nervure 9 est disposée parallèlement à la pluralité de canaux 4 de circulation de la portion de la plaque inférieure 3 sur laquelle est disposée la plaque de renfort 1. [68] The rib 9 comprises a main direction of extension, said direction being arranged in a plane of the reinforcing plate 1 and in a direction secant to the main orientation of the plurality of circulation channels 4 of the portion of the lower plate 3 on which the reinforcing plate 1 is placed, preferably perpendicular to the main orientation of the circulation channels 4 of the portion of the lower plate 3 on which the reinforcing plate 1 is placed. It is thus understood that said main orientation of the channels 4 is that of the channels 4 configured to be arranged opposite the first section 7 of the reinforcing plate 1, said first section 7 comprising F at least one rib 9. By main orientation of the plurality of channels, it is necessary to understand the orientation of the most important dimension in which the channels 4 to be considered extend. Thus in the examples of Figures 1 and 2, the ribs 9 of the reinforcing plate 1 extend perpendicular to the channels 4 placed under these ribs 9. In Figures 1 and 2, the channels 4 extend mainly in the length of the lower plate 3 and therefore the ribs 9 extend mainly in a direction arranged along the width of the lower plate 3. [69] Alternatively, the rib 9 is arranged parallel to the plurality of circulation channels 4 of the portion of the lower plate 3 on which the reinforcing plate 1 is arranged.
[70] La plaque de renfort 1 comprend une surface supérieure 10 configurée pour être en contact avec l’au moins une portion de la plaque inférieure 3, la nervure 9 est formée par une cavité s’étendant depuis la surface supérieure 10 de la plaque de renfort 1 et perpendiculairement à la plaque inférieure 3 du dispositif 100 de régulation thermique. De façon avantageuse, la nervure 9 peut être obtenue par emboutissage de la plaque de renfort 1 , ainsi la plaque de renfort 1 tout en conservant la robustesse procurée par la nervure 9 permet d'optimiser la quantité de matière nécessaire à l’obtention de la pièce. [70] The reinforcing plate 1 comprises an upper surface 10 configured to be in contact with the at least one portion of the lower plate 3, the rib 9 is formed by a cavity extending from the upper surface 10 of the plate reinforcement 1 and perpendicular to the lower plate 3 of the thermal regulation device 100. Advantageously, the rib 9 can be obtained by stamping the reinforcing plate 1, thus the reinforcing plate 1 while retaining the robustness provided by the rib 9 makes it possible to optimize the quantity of material necessary to obtain the piece.
[71] La cavité peut comprendre un isolant thermique. [71] The cavity may include a thermal insulator.
[72] On comprend également que la nervure 9 peut être obtenue par extrusion ou moulage de la plaque de renfort 1. La nervure 9 peut être venue de matière et dépourvue de cavité, c’est-à-dire que depuis une vue en coupe transversale de la plaque de renfort 1 , la nervure 9 serait pleine de matière. [72] It is also understood that the rib 9 can be obtained by extrusion or molding of the reinforcing plate 1. The rib 9 can be made from material and devoid of cavity, that is to say only from a sectional view transversal of the reinforcing plate 1, the rib 9 would be full of material.
[73] La plaque de renfort 1 comprend une pluralité de nervures 9 telles que décrites précédemment. [73] The reinforcing plate 1 comprises a plurality of ribs 9 as described previously.
[74] La pluralité de nervures 9 comprend des nervures 9 de dimensions différentes, par exemple au moins une nervure 9 de dimension distincte des autres nervures 9 peut être disposée sur une périphérie de la plaque de renfort 1 ou de façon alternative, l’au moins une nervure 9 de dimension distincte peut être disposée au centre de la plaque de renfort 1. [74] The plurality of ribs 9 comprises ribs 9 of different dimensions, for example at least one rib 9 of a dimension distinct from the other ribs 9 can be arranged on a periphery of the reinforcing plate 1 or alternatively, the other least one rib 9 of distinct dimension can be arranged in the center of the reinforcing plate 1.
[75] La pluralité de nervures 9 comprend un ensemble de tronçons rectilignes 90 et parallèles entre eux. On comprend que ce sont ces tronçons rectilignes 90 qui définissent l’orientation principale d’allongement des nervures 9. [75] The plurality of ribs 9 comprises a set of rectilinear sections 90 which are parallel to each other. We understand that it is these rectilinear sections 90 which define the main orientation of elongation of the ribs 9.
[76] La pluralité de nervures 9 comprend des tronçons 91 présentant une forme en U reliant des tronçons rectilignes 90 voisins. [76] The plurality of ribs 9 comprises sections 91 having a U shape connecting neighboring rectilinear sections 90.
[77] De façon alternative, les tronçons 91 en U peuvent être remplacés par des tronçons droit ou en forme de V. [77] Alternatively, the U-shaped sections 91 can be replaced by straight or V-shaped sections.
[78] De façon non illustrée dans les figures, la pluralité de nervures 9 comprend au moins deux groupes de nervures 9, chaque groupe de nervures 9 étant configuré pour être disposé en vis-à-vis d’une portion différente de la pluralité de canaux 4. [78] Not illustrated in the figures, the plurality of ribs 9 comprises at least two groups of ribs 9, each group of ribs 9 being configured to be arranged facing a different portion of the plurality of ribs. channels 4.
[79] Chacun des groupes de nervures 9 est configuré pour être disposé sur des portion de la pluralité de canaux 4 ayant une direction principale d’extension différente d’une autre portion. [80] Un des groupes de nervures 9 comprend au moins deux nervures 9, chacun d’elles étant disposée sur au moins un côté d’un autre groupe de nervure, lesdites nervures 9 disposées sur les côtés peuvent avoir des dimensions différentes des nervures 9 du groupe qu’elle jouxte, préférentiellement des dimensions plus importantes. Ceci permet d’adapter la rigidité de la plaque de renfort 1 de façon optimale en fonction du dispositif 100 de régulation thermique. [79] Each of the groups of ribs 9 is configured to be arranged on portions of the plurality of channels 4 having a main direction of extension different from another portion. [80] One of the groups of ribs 9 comprises at least two ribs 9, each of them being arranged on at least one side of another group of ribs, said ribs 9 arranged on the sides can have dimensions different from the ribs 9 of the group it adjoins, preferably larger dimensions. This makes it possible to adapt the rigidity of the reinforcing plate 1 optimally as a function of the thermal regulation device 100.
[81] Tel qu’illustré aux figures 1 et 2, la plaque de renfort 1 comprend sur au moins une portion de son pourtour une paroi périphérique 10 s’étendant principalement perpendiculairement aux plans d’allongement principal de la plaque supérieure 2 et de la plaque inférieure 3. Ainsi, et de façon avantageuse, la paroi 10 augmente davantage la résistance de la plaque de renfort 1, notamment pour des contraintes mécaniques de torsion et de flexion sur la plaque inférieure 3 du dispositif 100 de régulation thermique. [81] As illustrated in Figures 1 and 2, the reinforcing plate 1 comprises on at least a portion of its periphery a peripheral wall 10 extending mainly perpendicular to the main elongation planes of the upper plate 2 and the lower plate 3. Thus, and advantageously, the wall 10 further increases the resistance of the reinforcing plate 1, in particular for mechanical stresses of torsion and bending on the lower plate 3 of the thermal regulation device 100.
[82] La paroi 10 est venu de matière avec la plaque de renfort 1, préférentiellement obtenue par emboutissage. [82] The wall 10 comes in one piece with the reinforcing plate 1, preferably obtained by stamping.
[83] Selon un premier mode de réalisation de l’invention tel qu’illustré à la figure 1, une seule plaque de renfort est disposée sur le dispositif de régulation thermique. La plaque de renfort 1 couvre 25% de préférence 50% encore préférentiellement la totalité de la surface de la plaque inférieure 3. [83] According to a first embodiment of the invention as illustrated in Figure 1, a single reinforcing plate is placed on the thermal regulation device. The reinforcing plate 1 covers 25%, preferably 50%, more preferably the entire surface of the lower plate 3.
[84] Tel qu’illustré à la figure 2 et selon un second mode de réalisation de l’invention, l’invention a également pour objet un dispositif de renfort 200 comprenant une pluralité de plaques de renfort 1 telles que la plaque de renfort 1 précédemment décrite et configurées pour être fixées à une même plaque inférieure 3 d’un dispositif 100 de régulation thermique. [84] As illustrated in Figure 2 and according to a second embodiment of the invention, the invention also relates to a reinforcement device 200 comprising a plurality of reinforcement plates 1 such as the reinforcement plate 1 previously described and configured to be fixed to the same lower plate 3 of a thermal regulation device 100.
[85] Chaque plaque 1 comprend au moins une nervure 9 telle que précédemment décrite. [85] Each plate 1 comprises at least one rib 9 as previously described.
[86] Chaque plaque de renfort 1 comprend au moins une nervure 9 orientée dans une direction autre que celle d’une nervure 9 d’une autre plaque 1. [86] Each reinforcing plate 1 comprises at least one rib 9 oriented in a direction other than that of a rib 9 of another plate 1.
[87] La plaque de renfort 1 a une forme préférentiellement similaire à la plaque inférieure 3 mais de façon alternative elle peut être d’une autre forme que la plaque inférieure 3. On comprend ainsi que lorsque la plaque inférieure 3 est de forme principalement plane, la plaque de renfort 1 est préférentiellement plane. [87] The reinforcing plate 1 has a shape preferably similar to the lower plate 3 but alternatively it can be of another shape than the lower plate 3. We thus understand that when the lower plate 3 is of mainly planar shape , the reinforcing plate 1 is preferably flat.
[88] La plaque de renfort 1 peut par exemple être un quadrilatère ou bien un polygone en forme de T. [88] The reinforcing plate 1 can for example be a quadrilateral or a T-shaped polygon.
[89] La plaque de renfort 1 est produite à partir de matériaux métalliques, préférentiellement en aluminium. Ces matériaux métalliques ayant pour avantage de ne pas être inflammables, contrairement aux tampons élastiques de l’art antérieur. De plus, ils peuvent offrir une meilleure résistance à l’usure ainsi qu’une meilleure recyclabilité. [90] De façon alternative, la plaque de renfort 1 peut être faite d’un matériau composite. Ceci aurait pour avantage de procurer une bonne résistance mécanique tout en alliant une plus grande légèreté par rapport aux matériaux métalliques, ce qui permet dans l’exemple d’une utilisation dans un véhicule de réduire la consommation en énergie pour sa propulsion. [89] The reinforcing plate 1 is produced from metallic materials, preferably aluminum. These metallic materials have the advantage of not being flammable, unlike the elastic buffers of the prior art. Additionally, they can offer better wear resistance as well as better recyclability. [90] Alternatively, the reinforcing plate 1 can be made of a composite material. This would have the advantage of providing good mechanical resistance while combining greater lightness compared to metallic materials, which allows, in the example of use in a vehicle, to reduce energy consumption for its propulsion.
[91] La plaque de renfort 1 est brasée avec la plaque inférieure 3 et la plaque supérieure 2 du dispositif 100 de régulation thermique. [91] The reinforcement plate 1 is brazed with the lower plate 3 and the upper plate 2 of the thermal regulation device 100.
[92] De façon alternative, la plaque de renfort 1 peut être soudée par laser sur la plaque inférieure 3 du dispositif 100 de régulation thermique. [92] Alternatively, the reinforcing plate 1 can be laser welded to the lower plate 3 of the thermal regulation device 100.
[93] Encore de façon alternative, la plaque de renfort 1 peut être rivetée sur la plaque inférieure 3 du dispositif 100 de régulation thermique. [93] Still alternatively, the reinforcement plate 1 can be riveted to the lower plate 3 of the thermal regulation device 100.
[94] Il est également possible que la plaque de renfort 1 soit collée à la plaque inférieure 3 du dispositif 100 de régulation thermique. [94] It is also possible that the reinforcement plate 1 is glued to the lower plate 3 of the thermal regulation device 100.
[95] La plaque de renfort 1 a une épaisseur entre 0,5 et 1,3 mm. [95] The reinforcement plate 1 has a thickness between 0.5 and 1.3 mm.
[96] Le dispositif 100 de régulation thermique peut comprendre des emplacements pour recevoir les composants à refroidir, notamment des cellules de batterie, le module 300 peut comprendre également une pluralité de plaques de renfort 1, chaque plaque de renfort 1 étant disposée en vis- à-vis d’un emplacement. [96] The thermal regulation device 100 may include locations for receiving the components to be cooled, in particular battery cells, the module 300 may also include a plurality of reinforcing plates 1, each reinforcing plate 1 being arranged opposite each other. towards a location.
[97] La plaque inférieure 3 et la plaque supérieure 2 ont pour chacune d’elles une épaisseur pouvant aller jusqu’à 3 mm, plus souvent entre 0,8 mm et 1,3 mm. [97] The lower plate 3 and the upper plate 2 each have a thickness of up to 3 mm, more often between 0.8 mm and 1.3 mm.
[98] Le fluide caloporteur peut notamment être un fluide réfrigérant, notamment un fluide choisi parmi les fluides réfrigérants R134a, R1234yf, R744 ou un mélange eau glycol. [98] The heat transfer fluid may in particular be a refrigerant fluid, in particular a fluid chosen from the refrigerant fluids R134a, R1234yf, R744 or a water glycol mixture.
[99] La pluralité de canaux 4 peut comprendre des canaux principalement rectilignes ou courbes. [99] The plurality of channels 4 may comprise mainly rectilinear or curved channels.
[100] La pluralité de canaux 4 peut comprendre des sections rectilignes reliées à des sections courbes. [100] The plurality of channels 4 may comprise rectilinear sections connected to curved sections.

[102] Les canaux 4 s’étendent depuis une face de la plaque inférieure 3 en contact avec une face de la plaque supérieure 2 dans un sens opposé à cette face. [102] The channels 4 extend from one face of the lower plate 3 in contact with one face of the upper plate 2 in a direction opposite to this face.
[103] Les canaux 4 sont formés par des cavités formées dans la plaque inférieure 3 et obstruées par l’empilement avec la plaque supérieure 2. [103] The channels 4 are formed by cavities formed in the lower plate 3 and obstructed by the stacking with the upper plate 2.
[104] L’épaisseur de la plaque inférieure 3 étant inférieure à la largeur des canaux 4, les cavités formant les canaux 4 forment des saillies s’étendant vers l’extérieur depuis une face opposée à la face en contact avec la plaque supérieure 2. [105] La plaque de renfort 1 est en contact uniquement avec les saillies de la plaque inférieure 3. [104] The thickness of the lower plate 3 being less than the width of the channels 4, the cavities forming the channels 4 form projections extending outwards from a face opposite the face in contact with the upper plate 2 . [105] The reinforcement plate 1 is in contact only with the projections of the lower plate 3.
[106] Les canaux 4 s’étendent entre une entrée commune et une sortie commune de fluide caloporteur. [106] Channels 4 extend between a common inlet and a common outlet of heat transfer fluid.
[107] Une bride peut être connectée à cette entrée et sortie pour assurer des raccordements. [107] A flange can be connected to this inlet and outlet to provide connections.
[108] La plaque de renfort 1 comprend des moyens de fixation 11 configurés pour fixer le dispositif 100 de régulation thermique à un châssis. [108] The reinforcement plate 1 comprises fixing means 11 configured to fix the thermal regulation device 100 to a chassis.
[109] Les moyens de fixation 11 peuvent comprendre des orifices 110 traversant de part en part la plaque de renfort 1 et configurés pour recevoir des éléments de fixations tels que des vis, rivets et autres éléments similaires connus de l’homme du métier. [109] The fixing means 11 may comprise orifices 110 passing right through the reinforcing plate 1 and configured to receive fixing elements such as screws, rivets and other similar elements known to those skilled in the art.
[110] Les orifices 110 de la plaque de renfort 1 peuvent être disposés selon des groupements rectilignes en travers de la plaque de renfort 1. [110] The orifices 110 of the reinforcement plate 1 can be arranged in rectilinear groups across the reinforcement plate 1.
[111] Les orifices 110 peuvent de façon alternative ou en complément être disposés sur la périphérie de la plaque de renfort 1. [111] The orifices 110 can alternatively or in addition be arranged on the periphery of the reinforcing plate 1.
[112] La plaque supérieure 2 et/ou la plaque inférieure 3 peuvent comprendre au moins une patte de fixation 12 s’étendant depuis un bord de la plaque supérieure 2 et/ou de la plaque inférieure 3, la patte de fixation 12 comprenant de préférence au moins un orifice 110 des moyens de fixation 11.
