La présente invention concerne un compartiment pour un équipement susceptible de dégager de la chaleur lors de son fonctionnement, notamment pour un dispositif de stockage d'énergie électrique pour véhicule automobile.The present invention relates to a compartment for equipment capable of releasing heat during its operation, in particular for an electrical energy storage device for a motor vehicle.
Les demandes de brevet US2017176108 et WO 2013056938 décrivent des échangeurs de chaleur pour refroidir des cellules de batterie. Par ailleurs la demande de brevet US 2011/0206967 A décrit un exemple de telle batterie. Dans cette demande, les cellules sont stockées dans des containers ayant des logements de réception des cellules. Une paroi des containers, destinées à être en contact avec une paroi d’un container voisin présente des renfoncements formant une partie de conduit de circulation d’un fluide caloporteur.Patent applications US2017176108 and WO 2013056938 describe heat exchangers for cooling battery cells. Furthermore, patent application US 2011/0206967 A describes an example of such a battery. In this application, the cells are stored in containers having housings for receiving the cells. A wall of the containers, intended to be in contact with a wall of a neighboring container, has recesses forming part of a conduit for the circulation of a heat transfer fluid.
D’une manière générale, de nos jours, les plaques de refroidissement sont assemblées avec le boitier à batterie par des vis par exemple.In general, nowadays, the cooling plates are assembled with the battery box by screws for example.
La présente invention vise notamment à simplifier la fabrication d’un compartiment pour recevoir des cellules de batterie, notamment concernant l’assemblage des éléments de refroidissement avec le reste du compartiment.The present invention aims in particular to simplify the manufacture of a compartment for receiving battery cells, in particular concerning the assembly of the cooling elements with the rest of the compartment.
La présente invention a ainsi pour objet un compartiment pour un équipement susceptible de dégager de la chaleur lors de son fonctionnement, notamment pour un dispositif de stockage d'énergie électrique pour véhicule automobile, ce compartiment comportant au moins un canal de circulation d’un fluide de refroidissement, le canal étant formé entre une paroi d’interface thermique et une paroi de fond du compartiment, cette paroi d’interface et cette paroi de fond étant assemblées mécaniquement entre elles par un élément de liaison mécanique qui est au moins partiellement en matière plastique et étant en contact avec les deux parois.The subject of the present invention is thus a compartment for equipment capable of releasing heat during its operation, in particular for an electrical energy storage device for a motor vehicle, this compartment comprising at least one channel for the circulation of a fluid cooling, the channel being formed between a thermal interface wall and a bottom wall of the compartment, this interface wall and this bottom wall being mechanically assembled together by a mechanical connecting element which is at least partially made of material plastic and being in contact with both walls.
Grâce à l’invention, il est possible de réduire l’encombrement en hauteur du compartiment, notamment du fait d’un nombre optimisé de pièces nécessaires et de l’assemblage direct des parois d’interface et de fond ensemble. La hauteur est la direction perpendiculaire aux plans principaux des parois de fond et d’interface.Thanks to the invention, it is possible to reduce the overall height of the compartment, in particular due to an optimized number of parts required and the direct assembly of the interface and bottom walls together. The height is the direction perpendicular to the main planes of the bottom and interface walls.
De même le poids global peut être réduit.Also the overall weight can be reduced.
Notamment dans le cas où la paroi d’interface est en aluminium et la paroi de fond en matériau composite à base de polymère avec une charge, par exemple une charge de fibres de verre, l’invention permet de réduire les sollicitations mécaniques au niveau des contacts entre la paroi d’interface et la paroi de fond, du fait des éléments de liaison mécaniques.In particular in the case where the interface wall is made of aluminum and the bottom wall of composite material based on a polymer with a filler, for example a filler of glass fibers, the invention makes it possible to reduce the mechanical stresses at the level of the contacts between the interface wall and the bottom wall, due to the mechanical connecting elements.
L’invention permet ainsi d’augmenter la robustesse de l’ensemble.The invention thus makes it possible to increase the robustness of the assembly.

Selon l’un des aspects de l’invention, l’élément de liaison comporte des élargissements en appui sur les deux parois, et entre ces élargissements, une tige passant dans les deux orifices des parois.According to one of the aspects of the invention, the connecting element comprises enlargements resting on the two walls, and between these enlargements, a rod passing through the two orifices of the walls.
Selon l’un des aspects de l’invention, ces élargissements maintiennent serrées les parois l’une contre l’autre.According to one of the aspects of the invention, these enlargements hold the walls tight against each other.

Selon l’un des aspects de l’invention, les parois d’interface et de fond comporte un rebord et il est prévu une bande surmoulée qui longe ce rebord pour maintenir serrées les parois le long de ce rebord.According to one of the aspects of the invention, the interface and bottom walls have a rim and there is provided an overmolded strip which runs along this rim to keep the walls tight along this rim.
Selon l’un des aspects de l’invention, cette bande présente une forme, en section transversale, en forme de U pour venir enserrer les deux parois le long de leur rebord.According to one of the aspects of the invention, this strip has a shape, in cross section, U-shaped to grip the two walls along their edge.
Selon l’un des aspects de l’invention, la paroi d’interface est en métal, notamment en aluminium.According to one of the aspects of the invention, the interface wall is made of metal, in particular aluminum.
Selon l’un des aspects de l’invention, la paroi d’interface comporte une colonne creuse qui s’étend à travers un orifice de la paroi de fond, et cette colonne creuse sert à recevoir un organe de fixation du type vis ou tirant, pour fixer le compartiment à une pièce du véhicule.According to one of the aspects of the invention, the interface wall comprises a hollow column which extends through an orifice in the bottom wall, and this hollow column is used to receive a fixing member of the screw or tie type , to fix the compartment to a part of the vehicle.
