Said compression element 1 comprises a spring-loaded armature 7 provided with opposite edges 9 intended to extend in a so-called contact direction. This direction is in Figures 2 and 3 perpendicular to the plane of the drawing and corresponds to the longitudinal extension of at least one tube 1 1 of said heat exchanger, against which said compression member 1 is intended to apply. Said edges 9 are configured to bear on a bearing surface 13, which may be that of the housing of the battery 5, for example a housing housing of the battery mounted on the vehicle, not shown.
Le dispositif est disposé en particulier sous la batterie 5, voir les figures 2 et 3, et est destiné à plaquer le ou les tubes 1 1 de l'échangeur de chaleur 3 contre la face de dessous 15 de la batterie 5. The device is arranged in particular under the battery 5, see FIGS. 2 and 3, and is intended to press the tube or tubes 1 1 of the heat exchanger 3 against the bottom face 15 of the battery 5.
En variante, le dispositif pourrait mettre le ou les tubes 1 1 en contact avec une autre face de la batterie, non représenté, par exemple une face latérale ou une face de dessus de la batterie. Alternatively, the device could put the tube or 1 1 in contact with another side of the battery, not shown, for example a side face or a top face of the battery.
Ladite armature 7 comprend un sommet 17 s'étendant selon ladite direction de contact d, entre lesdits bords opposés 9 de l'élément de compression 1 . Selon l'invention, ladite armature 7 est configurée pour exercer un effort sur ledit échangeur 3, voir les figures 2 et 3, notamment le ou lesdits tubes 1 1 , par ledit sommet 17. Grâce à ladite armature ressort 7, les éventuels jeux de montage, notamment contre le ou lesdits tubes 1 1 de l'échangeur, sont absorbés et le contact entre la batterie 5 et l'échangeur 3 est optimisé. Said armature 7 comprises a top 17 extending in said contact direction d between said opposite edges 9 of the compression element 1. According to the invention, said armature 7 is configured to exert a force on said exchanger 3, see FIGS. 2 and 3, in particular said tube or tubes 1 1, by said apex 17. Thanks to said spring armature 7, the possible sets of mounting, in particular against the said tube or tubes 1 1 of the exchanger, are absorbed and the contact between the battery 5 and the exchanger 3 is optimized.
L'effort peut être exercé directement ou indirectement sur le ou lesdits tubes 1 1 de l'échangeur. L'élément de compression 1 appuie ainsi sur le ou lesdits tubes 1 1 avec ou sans partie support intermédiaire 19. The force can be exerted directly or indirectly on the tube or tubes 1 1 of the exchanger. The compression element 1 thus bears on the tube or tubes 1 1 with or without intermediate support part 19.
Lesdits bords 9 peuvent s'étendre en continu selon la direction de contact d, et de même ledit sommet 17 comme on le voit à la figure 1. L'élément de compression 1 a alors avantageusement une forme générée par une droite se déplaçant perpendiculairement à un même plan, facile à réaliser. Said edges 9 can extend continuously in the contact direction d, and likewise said vertex 17 as seen in FIG. 1. The compression element 1 then advantageously has a shape generated by a straight line moving perpendicularly to the same plan, easy to achieve.
Ainsi, l'armature 7 est, par exemple, un ressort en forme de bande à sommet 17 arrondi comme ici, ou plat, c'est à dire en forme sensiblement de gouttière renversée. Thus, the armature 7 is, for example, a strip-shaped spring with a rounded top 17 as here, or flat, that is substantially in the shape of an inverted channel.
Ledit sommet 17 du ressort est apte à être disposé, en compression, en contact contre ledit tube 1 1 et/ou contre ledit support intermédiaire 19 dudit tube, comme représenté à la figure 3. Said top 17 of the spring is able to be placed, in compression, in contact against said tube 1 1 and / or against said intermediate support 19 of said tube, as represented in FIG. 3.
Ladite bande de ressort 7 est apte à être montée flexible sur la surface d'appui 13 pour s'appliquer contre le ou lesdits tubes 1 1 et/ou le support intermédiaire 19. Elle est notamment apte à s'étendre en largeur au cours de la flexion. Ladite bande de ressort 7 comporte ici deux jambes opposées 21 , notamment symétriques par rapport à un plan longitudinal médian P de la bande. Lesdites jambes 21 sont configurées pour être mobiles sur la surface d'appui 13, notamment par leurs bords 9 qui sont ici pour cela repliés sur eux- mêmes, par exemple vers l'extérieur. Said spring strip 7 is able to be mounted flexibly on the bearing surface 13 to bear against the said tube (s) 1 1 and / or the intermediate support 19. It is particularly capable of extending in width during flexion. Said spring strip 7 here comprises two opposite legs 21, in particular symmetrical with respect to a median longitudinal plane P of the strip. Said legs 21 are configured to be movable on the support surface 13, in particular by their edges 9 which are here for that folded on themselves, for example outwardly.
En variante non illustrée, lesdites deux jambes opposées 21 peuvent comporter des pattes, par exemple résultant de découpe des jambes 21 , destinées à être appliquées sur la surface d'appui 13. In a non-illustrated variant, said two opposite legs 21 may comprise tabs, for example resulting from cutting the legs 21, intended to be applied to the bearing surface 13.
Ladite bande de ressort 7 est avantageusement d'épaisseur égale à environ 0, 1 à 0,4 mm, de préférence d'épaisseur comprise entre 0.15 et 0.2 mm, constituée de matière métallique, notamment d'acier à haute caractéristique élastique. Ces caractéristiques renforcent la capacité de flexion pour s'adapter à l'échangeur. Said spring strip 7 is advantageously of thickness equal to about 0.1 to 0.4 mm, preferably of thickness between 0.15 and 0.2 mm, made of metallic material, in particular steel with high elastic characteristic. These characteristics reinforce the bending capacity to adapt to the exchanger.
Ladite bande de ressort 7 a une section régulière, notamment de sommet 17 arrondi, en particulier symétrique relativement au plan longitudinal médian P, ce qui facilite sa fabrication. Said spring strip 7 has a regular section, in particular rounded vertex 17, in particular symmetrical relative to the median longitudinal plane P, which facilitates its manufacture.
Elle a une longueur comprise entre 200 et 500 millimètres, adaptée à la longueur du ou desdits tubes 1 1 . It has a length of between 200 and 500 millimeters, adapted to the length of said tube (s) 1 1.
Plus précisément, ledit élément de compression 1 est configuré pour supporter le ou lesdits tubes 1 1 par une bande de contact 25, par exemple le long dudit plan longitudinal médian P. En particulier, au cours de la flexion, l'armature 7 s'adapte pour venir en appui sur l'échangeur 3 selon ladite bande 25. Ledit élément de compression 1 peut aussi être configuré pour supporter le ou lesdits tubes 1 1 par une pluralité de points de contact ou une ligne de contact 27, en particulier le long dudit plan longitudinal médian P. Lesdites pluralités de points 25, ligne de contact 27 et bande de contact s'étendent sur la longueur de l'élément de compression 1 , notamment de la bande de ressort 7. More specifically, said compression element 1 is configured to support the tube or tubes 1 1 by a contact strip 25, for example along said median longitudinal plane P. In particular, during bending, the armature 7 is adapted to bear on the exchanger 3 according to said strip 25. Said compression element 1 can also be configured to support the tube or tubes 1 1 by a plurality of contact points or a contact line 27, in particular along said median longitudinal plane P. Said plurality of points 25, contact line 27 and contact strip extend along the length of the compression element 1, in particular of the spring strip 7.
En variante, elles pourraient s'étendre sur une partie de l'élément de compression 1 correspondant à la zone de contact entre ce dernier et l'échangeur 3. As a variant, they could extend over a part of the compression element 1 corresponding to the zone of contact between the latter and the exchanger 3.
Ledit élément de compression 1 est avantageusement configuré pour supporter le ou lesdits tubes 1 1 en étant isolé électriquement de ladite surface d'appui 13, par exemple par une couche de matière diélectrique intermédiaire. Ainsi, on prévient tout phénomène de corrosion entre l'échangeur et l'élément de compression. Said compression element 1 is advantageously configured to support the at least one tube 1 1 being electrically isolated from said bearing surface 13, for example by a layer of intermediate dielectric material. Thus, it prevents any corrosion phenomenon between the exchanger and the compression element.
Ledit élément de compression 1 comporte avantageusement au moins un renfort 29 d'extrémité longitudinale, notamment au niveau des jambes 21 de ladite bande de ressort. Ledit renfort 29 est apte à renforcer la résistance mécanique d'extrémité de l'élément de compression pour accroître l'homogénéité du contact d'application de ce dernier sur le tube. Ici, le ou lesdits renforts 29 sont des plis de bords, à l'extrémité de chacune des jambes 21 , notamment tournés vers l'intérieur de la bande de ressort 7. Said compression element 1 advantageously comprises at least one longitudinal end reinforcement 29, in particular at the level of the legs 21 of said spring strip. Said reinforcement 29 is capable of reinforcing the end mechanical strength of the compression element to increase the homogeneity of the application contact of the latter on the tube. Here, the one or more reinforcements 29 are edge folds, at the end of each of the legs 21, in particular turned towards the inside of the spring strip 7.
Autrement dit, ladite bande de ressort 7 comprend à l'une au moins, voire à chacune de ses extrémités longitudinales, un tel pli, issu de matière de ladite bande de ressort. Le ou lesdits plis 29 sont situés au niveau de l'une au moins des jambes 21 , voire au niveau de chacune desdites jambes 21 . Ils s'étendent, par exemple, à partir d'une zone sensiblement plane desdites jambes 21 , prévue entre ledit sommet 17 et lesdits bords 9. In other words, said spring strip 7 comprises at least one, or even at each of its longitudinal ends, such a ply, derived from material of said spring strip. The said ply (s) 29 are situated at the level of at least one of the legs 21, or even at the level of each of said legs 21. They extend, for example, from a substantially flat area of said legs 21, provided between said top 17 and said edges 9.
L'invention concerne également l'ensemble 30 d'un échangeur de chaleur 3 comprenant un ou des tubes 1 1 , et d'un élément de compression 1 tel que décrit ci-dessus, supportant le ou lesdits tubes 1 1 . The invention also relates to the assembly 30 of a heat exchanger 3 comprising one or more tubes 1 1, and a compression element 1 as described above, supporting said tube (s) 1 1.
Selon une première variante de réalisation de l'invention, l'élément de compression 1 est en contact avec le ou lesdits tubes 1 1 de l'échangeur. According to a first embodiment of the invention, the compression element 1 is in contact with the said tube or tubes 1 1 of the exchanger.
Selon une autre variante illustrée à la figure 3, l'échangeur 3 comprend un support intermédiaire 19 du ou desdits tubes 1 1 et l'élément de compression 1 est en contact avec ledit support intermédiaire 19. Ledit support intermédiaire 19 est avantageusement configuré pour être monté en clippage sur le ou lesdits tubes 1 1 . According to another variant illustrated in FIG. 3, the exchanger 3 comprises an intermediate support 19 of said tube or tubes 1 1 and the compression element 1 is in contact with said intermediate support 19. Said intermediate support 19 is advantageously configured to be mounted in clipping on said tube (s) 1 1.
Ce support intermédiaire 19 comporte avantageusement une base 31 , laquelle comprend, comme cela est visible à la figure 3, une première face 33 conformée pour supporter le tube 1 1 de façon isolée thermiquement et une seconde face 35 sur laquelle l'élément de compression 1 est destiné à être appliqué lorsque ce dernier est mis en pression. This intermediate support 19 advantageously comprises a base 31, which comprises, as can be seen in FIG. 3, a first face 33 shaped to support the tube 1 1 in a thermally insulated manner and a second face 35 on which the compression element 1 is intended to be applied when the latter is pressurized.
Lesdites première et seconde faces 33, 35 sont avantageusement opposées l'une à l'autre, de sorte que l'effort appliqué par l'élément de compression 1 sur la seconde face 35, selon la flèche de la figure, est transmis directement au tube 1 1 par la première face 33. Said first and second faces 33, 35 are advantageously opposed to each other, so that the force applied by the compression element 1 on the second face 35, according to the arrow of the figure, is transmitted directly to the tube 1 1 by the first face 33.
On pourrait encore prévoir un renvoi de l'effort dans une direction orientée inclinée, autre que celle de l'exemple. Ladite base 31 est avantageusement pourvue de nervures 37 sur sa première face, destinées à être appliquées sur le tube par leur extrémité, ce qui renforce un maintien isolé thermiquement du tube par la base. Cette isolation thermique résulte également de la matière de la base, avantageusement isolante de la chaleur, par exemple en matière plastique isolante. Une isolation électrique avec le tube est également assurée. One could also provide a reference of the force in an inclined oriented direction, other than that of the example. Said base 31 is advantageously provided with ribs 37 on its first face, intended to be applied to the tube at their end, which reinforces a thermally insulated support of the tube by the base. This thermal insulation also results from the material of the base, advantageously insulating heat, for example insulating plastic material. Electrical insulation with the tube is also provided.
L'élément de compression 1 est monté flexible sur la base 31 , à savoir qu'il peut s'étendre contre la base, notamment en largeur pour mettre en pression le tube 1 1 contre la batterie 5. The compression element 1 is flexibly mounted on the base 31, namely that it can extend against the base, in particular in width to pressurize the tube 1 1 against the battery 5.
Ledit sommet arrondi 17 du ressort est avantageusement reçu dans une zone concave ou un évidement 39 de ladite seconde face, ce qui permet de faciliter le maintien en position du ressort sur la seconde face. Said rounded crown 17 of the spring is advantageously received in a concave zone or a recess 39 of said second face, which makes it easier to hold the spring in position on the second face.
Ledit évidement 39 est en outre conformé selon l'exemple pour correspondre à une extension maximale du ressort. Said recess 39 is further shaped according to the example to correspond to a maximum extension of the spring.
En outre, ladite base 31 est pourvue de parties de clippage 41 du tube comme mentionné précédemment, notamment de pattes 41 de maintien de tube sur ses cotés longitudinaux. Ces pattes 41 sont aptes à prendre en tenaille, par clippage, le tube sans faire contact avec la batterie. In addition, said base 31 is provided with clipping portions 41 of the tube as mentioned above, in particular tabs 41 for holding tubes on its longitudinal sides. These tabs 41 are adapted to grip the tube by clipping without making contact with the battery.
Des éléments de liaison de l'élément de compression au support intermédiaire peuvent en outre être prévus, non représentés, par exemple des crochets disposés régulièrement sur la longueur de la base, montés traversant dans l'élément de compression. Connecting elements of the compression element to the intermediate support may also be provided, not shown, for example hooks arranged regularly along the length of the base, mounted through in the compression element.
L'invention concerne également une batterie 5 comprenant un tel ensemble 30. L'échangeur est en particulier configuré pour être appliqué contre au moins une face 15 de la batterie pour son refroidissement. Dans ladite batterie, les tubes 1 1 sont en particulier appliqués contre une face de dessous 15 de la batterie en vue de son refroidissement. The invention also relates to a battery 5 comprising such an assembly 30. The exchanger is in particular configured to be applied against at least one face 15 of the battery for cooling. In said battery, the tubes 1 1 are in particular applied against a bottom face 15 of the battery for cooling purposes.
Ledit échangeur comprend, par exemple, une pluralité de tubes 1 1 , chacun associé à un élément de compression, ou à un ensemble d'un élément de compression et d'un support intermédiaire, tel que décrit plus haut. A la figure 1 , l'un desdits tubes est représenté en coupe transversal. Il s'agit ici d'un tube plat, notamment extrudé, muni d'une pluralité de canaux de passage d'un liquide caloporteur, notamment un liquide de refroidissement tel que de l'eau additionnée d'antigel. Ledit tube 1 1 comprend deux grandes faces, l'une située en contact dudit élément de compression, ou dudit support intermédiaire, et l'autre située en contact de ladite batterie 5. En variante, un même élément de compression, ou un même ensemble d'un élément de compression et d'un support intermédiaire, pourra être utilisé pour supporter plusieurs tubes dudit échangeur. Said exchanger comprises, for example, a plurality of tubes 1 1, each associated with a compression element, or with an assembly of a compression element and an intermediate support, as described above. In Figure 1, one of said tubes is shown in cross section. This is a flat tube, particularly extruded, provided with a plurality of channels for the passage of a coolant liquid, especially a cooling liquid such as water with antifreeze. Said tube January 1 comprises two large faces, one located in contact with said compression element, or said intermediate support, and the other located in contact with said battery 5. Alternatively, the same compression element, or the same set a compression element and an intermediate support, can be used to support several tubes of said exchanger.
Bien que non illustré, ledit échangeur comprend en outre, par exemple, des collecteurs dans lesquels lesdits tubes débouchent à chacune de leurs extrémités longitudinales. Lesdits tubes sont avantageusement disposés dans un même plan, parallèle à leurs grandes faces, de façon à pouvoir venir en contact d'une surface sensiblement plane de la batterie. L'invention apporte ainsi une solution simple, fiable et facile à mettre en œuvre pour assurer un transfert thermique efficace entre une batterie de véhicule et un échangeur de chaleur. Although not illustrated, said exchanger further comprises, for example, collectors in which said tubes open at each of their longitudinal ends. Said tubes are advantageously arranged in the same plane, parallel to their large faces, so as to come into contact with a substantially flat surface of the battery. The invention thus provides a simple, reliable and easy to implement solution to ensure efficient heat transfer between a vehicle battery and a heat exchanger.
