Detailed Description
First of all, it should be noted that the composition, characteristics, advantages and the like of the heat exchange device according to the present application will be described below by way of example, but it should be understood that all descriptions are given for illustration only and should not be construed as limiting the present application in any way. In this document, the terms "first," "second," and the like, herein are used solely for the purpose of distinguishing between and not necessarily for the purpose of describing a sequential or relative importance, and the term "coupled" or the like may encompass a particular element directly coupled to another element and/or indirectly coupled to another element. Furthermore, unless explicitly specified and limited otherwise, the dimensions, directions or positional relationships indicated by the technical terms "length", "width", "height", "upper", "top", "bottom", etc. are based on the dimensions, orientations or positional relationships shown in the drawings, are merely for convenience in describing the present application and to simplify the description, and are not to be construed as limiting the present application.
Furthermore, to any single technical feature described or implicit in the embodiments mentioned herein, or any single technical feature shown or implicit in the drawings, the application still allows any combination or deletion of any combination or deletion between these technical features (or their equivalents) to be continued without any technical obstacle, thereby obtaining still other embodiments of the application that may not be directly mentioned herein. In addition, general matters which have been well known to those skilled in the art are not described in detail herein.
Fig. 1 is an exploded view of the heat exchange device and battery of the present application, wherein the heat exchange device includes a heat exchange assembly 20 and a housing 30. The flexible heat exchange plate 22 of the heat exchange assembly 20 is disposed between the battery 10 and the housing 30, the battery 10 may include one or more battery cells, the heat exchange medium flows through the flexible heat exchange plate 22 to exchange heat with the bottom surface of the battery 10, and the flexible heat exchange plate 22 is disposed on the inner bottom surface of the housing 30.
Wherein, the shell 30 is made of a composite material with heat preservation performance, which can avoid or at least partially avoid heat exchange between the flexible heat exchange plate 22 and the environment outside the shell 30, thereby avoiding or at least partially avoiding the influence of the external environment temperature of the shell 30 on the flexible heat exchange plate 22, and ensuring the heat exchange capability of the heat exchange assembly to be utilized to the greatest extent. For example, when the temperature of the heat exchange assembly and/or the temperature of the heat exchange medium in the heat exchange assembly is lower than the ambient temperature outside the housing 30, conduction of heat from the external environment to the interior of the housing 30 may be avoided or reduced due to the insulating properties of the housing 30; when the temperature of the heat exchange assembly and/or the temperature of the heat exchange medium in the heat exchange assembly is higher than the ambient temperature outside the housing 30, heat transfer from the heat exchange assembly and/or the heat exchange medium in the heat exchange assembly to the external environment may be avoided or reduced due to the thermal insulation properties of the housing 30. The housing 30 may be made of an insulating composite material, and the heat exchange device can thus also achieve an insulating effect. On the premise of meeting the structural strength, compared with the metal shell used in the prior art, the shell 30 made of the composite material can also reduce the overall weight of the device and the manufacturing cost and the running load of the vehicle.
Alternatively, the flexible heat exchange plate 22 may also be disposed on the top and side of the battery 10 to exchange heat with the battery 10, and the housing 30 may also insulate the flexible heat exchange plate 22 accordingly. Although the housing 30 shown in fig. 1 has only a bottom surface and a side surface, in practical applications, the housing 30 may also have a top, and the top and the side surfaces of the housing 30 may correspondingly perform insulation and insulation protection on the flexible heat exchange plate 22.
Alternatively, the flexible heat exchange plate 22 may be replaced with a flexible heat exchange member of a different structure and/or shape, such as a flexible heat exchange tube.
Fig. 2 is an enlarged view of the heat exchange assembly 20, wherein the heat exchange assembly 20 includes a current collector 21, a flexible heat exchange plate 22, and an integral package pipe 23. The heat exchange assembly 20 in fig. 2 includes two whole package pipelines 23 and two flexible heat exchange plates 22, wherein the two whole package pipelines 23 are respectively connected with one ends of the two flexible heat exchange plates 22, and the other ends of the two flexible heat exchange plates 22 are respectively connected with the current collector 21. Preferably, the heat exchange medium flows from one of the whole package of tubes 23 in the figure into one end of one of the flexible heat exchange plates 22 and from the other end of the flexible heat exchange plate into the current collector 21, and then from the current collector 21 into the other of the flexible heat exchange plates 22 and out of the other of the whole package of tubes 23. Preferably, the flow path of the heat exchange medium in the heat exchange assembly 20 can be changed by setting the structure of the current collector 21, for example, a plurality of flexible heat exchange plates 22 can be set to be connected in series or in parallel by using the current collector 21, so as to adapt to different actual heat exchange requirements on the number and arrangement modes of the batteries under different conditions.
Fig. 3a and 3b are schematic views of the flexible heat exchanger plate 22 and the spacing structure 40, respectively, before and when the battery is mounted in place. The spacing structure 40 includes a protrusion 41 and a connection portion 42, and the flexible heat exchange plate 22 is located between the two protrusions 41. Alternatively, the spacing structure 40 may not include the connection portion 42. The flexible heat exchange plate 22 is made of a flexible material (e.g., rubber) having good heat conductive properties, which can be elastically deformed according to being pressed by the battery 10 so as to maintain good contact with the battery 10, and which can also be deformed following the deformation of the battery 10 when the battery 10 itself expands or contracts, so that it can secure a heat exchange effect. As can be seen from the figure, before the battery is mounted, i.e. as shown in fig. 3a, the flexible heat exchanger plate 22 is higher than the limit structure 40 in the height direction, and there is a gap between the side of the flexible heat exchanger plate 22 and the limit structure 40 in the width direction; when the battery is mounted in place, as shown in fig. 3b, the top of the flexible heat exchange plate 22 is in contact with the battery 10, so that heat exchange with the battery 10 is enabled, the flexible heat exchange plate 22 decreases in size in height and increases in size in width due to the force of the battery 10, and the gap between the flexible heat exchange plate 22 and the limit structure 40 decreases or disappears. Preferably, the flexible heat exchange plate is arranged in the limiting structure, and the maximum deformation of the flexible heat exchange plate can be adjusted by selecting the limiting structures with different heights. That is, for the higher height limit structure 40/protrusion 41, the maximum deformation amount of the flexible heat exchange plate 22 is relatively small; for the lower height limit structure 40/protrusions 41, the maximum deformation of the flexible heat exchanger plate 22 is relatively large.
The limiting structure 40 is positioned between the shell 30 and the battery 10, limits the installation position of the flexible heat exchange plate 22, and limits the compression thickness of the flexible heat exchange plate 22 to a certain extent, when the battery 10 is in contact with the limiting structure, the flexible heat exchange plate 22 reaches the compression upper limit, so that the flexible heat exchange plate 22 is prevented from bearing excessive extrusion force or being excessively deformed, the limiting structure 40 can protect the flexible heat exchange plate 22, and the excessive compression of the flexible heat exchange plate 22 to cause the excessive flow resistance of an internal flow channel of the flexible heat exchange plate is avoided; in addition, the limiting structure 40 can also limit the position of the battery 10, which is beneficial to the positioning of the battery 10 and the matching relationship between other components. In addition to the advantages described above, the limit structure 40 includes other advantages of the limit structure 40 that can be appreciated by those skilled in the art based on the teachings of the present application. The limiting structure 40 may be fixed on the housing 30 by welding, screwing, gluing, clamping, integrally forming, etc. The spacing structure 40 may be detachably connected to the battery by a snap fit, threaded connection, magnetic attraction, elastic connection, or the like, as is common in the art.
It should be noted that although in the embodiment of fig. 3a the height of the flexible heat exchanger plate 22 is higher than the limit structure 40, in other embodiments the height of the flexible heat exchanger plate 22 may be level with the limit structure 40 or lower than the limit structure 40, in which case the bottom of the battery 10 may have a protrusion to still be in contact with the flexible heat exchanger plate 22 when mounted in place with the limit structure 40.
It should be noted that although in the embodiment of fig. 3a both sides of the flexible heat exchanger plate 22 are not in contact with the inner surface of the limit structure 40, in other embodiments one or both sides of the flexible heat exchanger plate 22 may be in full contact or in partial contact with the limit structure 40. Accordingly, corresponding recesses or through slots may be provided on the sides of the spacing structure to accommodate the lateral increase in size of the flexible heat exchange plate 22 when the battery is in place.
It should be noted that although in the embodiment of fig. 3b both sides of the flexible heat exchanger plate 22 are in contact with the inner surface of the limit structure 40, in other embodiments one or both sides of the flexible heat exchanger plate 22 may be completely out of contact or partially in contact with the limit structure 40.
Due to the characteristics of deformability and heat conduction of the flexible heat exchange plate 22, a heat conduction gasket or a heat conduction caulking material and the like which are common in the prior art can be omitted, and the structure and the material use are simplified. At the same time, the arrangement of the flexible material can also reduce the weight of the heat exchange device and reduce the cost.
Alternatively, the person skilled in the art may control the amount of deformation of the flexible heat exchanger plate 22 by setting the dimensions of the limit structure in the height direction.
It should be noted that the flexible heat exchange plate 22 is not limited to being provided at the bottom surface of the battery 10, but may be provided at the side surface, the top portion of the battery to exchange heat with the battery 10. Accordingly, the limit structure 40 may also be provided at the side, top of the battery. Alternatively, the flexible heat exchange plates at the sides, top, bottom of the battery may also eliminate the provision of the limit structure 40. For example, in one non-limiting embodiment of the present application, the flexible heat exchange plate 22 at the bottom of the battery is correspondingly provided with a stopper structure, while the flexible heat exchange plate 22 at the side of the battery is not provided with a stopper structure due to the smaller pressure applied thereto.
Fig. 4 shows an exploded view of another embodiment of the heat exchange device and battery of the present application, wherein the flexible heat exchange plate 22 comprises a bottom flexible heat exchange plate 222 and a side flexible heat exchange plate 221 for exchanging heat with the bottom and side of the battery 10, respectively. Wherein, part of the side flexible heat exchange plate 221 is disposed between the battery cells, and part of the side flexible heat exchange plate 221 is disposed between the battery and the case 30. In the present embodiment, the bottom flexible heat exchange plate 222 and the side flexible heat exchange plate 221 are provided with current collectors at respective one/both ends and integral package pipes at respective one ends, the heat exchange medium enters the flexible heat exchange plate 22 through one of the integral package pipes and flows out of the flexible heat exchange plate 22 from the other of the integral package pipes after flowing through the flexible heat exchange plate 22, and the current collectors can adjust the flow path of the heat exchange medium in the heat exchange assembly by adjusting their own structures, and the connection manner such as serial connection, parallel connection, etc. between the flexible heat exchange plates, similar to the above-mentioned embodiments.
Fig. 5 is an enlarged view of the heat exchange assembly of fig. 4, which includes a bottom flexible heat exchange plate 222 and a side flexible heat exchange plate 221, which exchange heat with the bottom and side of the battery 10, respectively. The whole package pipe is connected with corresponding one ends of the two bottom flexible heat exchange plates 222 and the three side flexible heat exchange plates 221, and corresponding other ends of the two bottom flexible heat exchange plates 222 and the three side flexible heat exchange plates 221 are connected with a current collector. Alternatively, the current collector may be provided at one or both ends of the flexible heat exchange plate. Preferably, the number and the positions of the flexible heat exchange plates can be selected according to actual needs.
Fig. 6 is a cross-sectional view of a flexible heat exchanger plate 22, wherein the flexible heat exchanger plate 22 has a plurality of heat exchange medium flow passages 223, and the heat exchange medium flow passages 223 of the flexible heat exchanger plate 22 have a substantially parallelogram structure. The flexible heat exchange plate 22 may be produced by an extrusion process, and flexible heat exchange plates 22 having heat exchange medium flow channels 223 of different structures (e.g., having different heights, widths, inclination angles, flow paths) may be produced by selecting molds having different shapes and sizes. Preferably, the cross-sectional shape, size of the flexible heat exchange plate 22 and the size, cross-sectional shape, flow path, etc. of the heat exchange medium flow channels 223 may be selected or designed by a person skilled in the art according to the flow requirements of the heat exchange fluid.
