Referring to fig. 1, there is representatively illustrated an exploded perspective view of a portion of the structure of a battery device according to the present utility model. In this exemplary embodiment, the battery device according to the present utility model is described as being applied to a vehicle-mounted battery. Those skilled in the art will readily appreciate that many modifications, additions, substitutions, deletions, or other changes may be made to the embodiments described below for use in other types of battery devices or other processes, and such changes are within the scope of the principles of the battery device as set forth herein.
As shown in fig. 1, in an embodiment of the present utility model, the battery device according to the present utility model includes a plurality of batteries 100 and a plurality of heat exchange plates 200, and in fig. 1, two batteries 100 are separated and one of the batteries 100 is further separated from one of the heat exchange plates 200. In some embodiments, the battery device according to the present utility model may also include a battery 100 and a heat exchange plate 200, which is not limited to the present embodiment. In addition, the battery device provided by the utility model can be a battery module, and can also be a battery pack comprising the battery module and a box body. Referring to fig. 2 in conjunction, a schematic plan view of a heat exchange plate 200 of a battery device capable of embodying the principles of the present utility model is representatively illustrated in fig. 2. The structure, connection manner and functional relationship of the main components of the battery device according to the present utility model will be described in detail below with reference to the above-mentioned drawings.
As shown in fig. 1 and 2, in an embodiment of the present utility model, the heat exchange plate 200 is disposed on the first surface 101 of the battery 100, and the first surface 101 is a vertical surface, i.e., the heat exchange plate 200 is disposed along a vertical direction. On this basis, the heat exchange plate 200 has a liquid inlet 201, a liquid outlet 202 and a flow channel, the flow channel is connected between the liquid inlet 201 and the liquid outlet 202, and the flow channel comprises four branches, and the four branches comprise two first branches 210 and two second branches 220. The first branch 210 has a height difference section 211 and a continuous bending section 212, wherein the inlet of the height difference section 211 is higher than the outlet along the flowing direction of the heat exchange medium in the flow channel, and the continuous bending section 212 is in a continuous bending shape. Accordingly, when the heat exchange medium flows through the height difference section 211, the flow speed of the heat exchange medium is accelerated due to the gravity influence due to the fact that the height difference section 211 has a descending height difference from the inlet to the outlet. When the heat exchange medium flows through the continuous bending section 212, the continuous bending section 212 is in a continuous bending shape, so that the flow rate of the heat exchange medium is reduced. Through the above structural design, the continuous bending section 212 can be utilized to reduce the flow velocity of the first branch 210, so that the flow velocity increment of the first branch 210 due to the height difference section 211 is at least partially counteracted, the heat exchange between the heat exchange plate 200 and the battery 100 is more sufficient, and the heat exchange effect of the heat exchange plate 200 is improved.

On the basis, for two adjacent first branches 210, the length of the height difference section 211 of the first branch 210 located below is greater than the length of the height difference section 211 of the first branch 210 located above, and the length of the continuous bending section 212 of the first branch 210 located below is greater than the length of the continuous bending section 212 of the first branch 210 located above. Through the above structural design, the present utility model can further ensure that the flow velocity of the lower one of the two adjacent first branches 210 is lower, so as to further offset the flow velocity increment of the lower first branch 210 relative to the upper first branch 210 due to gravity, so that the flow velocity of each first branch 210 of the flow channel has better consistency, and further improve the heat exchange effect of the heat exchange plate 200.
As shown in fig. 2, in an embodiment of the present utility model, when the flow channel of the heat exchange plate 200 includes four branches, the four branches may be arranged at equal intervals, that is, the intervals between three pairs of adjacent two branches may be equal. Through the structural design, the uniformity of the heat exchange effect of the heat exchange plate 200 can be further optimized. In some embodiments, the flow channels of the heat exchange plate 200 may include different numbers of branches, and when the flow channels include at least three branches, that is, at least two pairs of two adjacent branches exist, the at least three branches may be arranged in an equidistant manner.

Through the structural design, the heat exchange plate 200 can facilitate the same side and liquid inlet and outlet of the heat exchange plate, facilitate the arrangement of external liquid inlet and outlet structures (such as pipelines and the like), and facilitate the reduction of space occupation along the second horizontal direction Y and the reduction of structural complexity.

Through the structural design, the utility model is beneficial to the reasonable arrangement of the liquid inlet 201, the liquid outlet 202 and the flow channels, avoids the problem of disordered arrangement of the flow channels and even structural interference caused by the fact that the liquid inlet 201 and the liquid outlet 202 are positioned at the same end part of the heat exchange plate 200 and have the same height, and can make use of the height difference between the liquid inlet 201 and the liquid outlet 202 to enable the heat exchange effect of the heat exchange medium flowing through to be better and more sufficient.
