The widths of the two first main runners farthest from the first plane are the same, the widths of the other first main runners are the same, and the widths of the two first main runners farthest from the first plane are smaller than those of the other first main runners. Since the two first main flow channels farthest from the first plane are all communicated with one first flow channel group, and the other first main flow channels are all communicated with two first flow channel groups, the flow rate entering each first flow channel group can be the same as much as possible by controlling the flow channel width of each first main flow channel.

The cross-sectional areas of the two first channels farthest from the first plane are the same, the cross-sectional areas of the other first channels are the same, the cross-sectional areas of the two first channels farthest from the first plane are smaller than the cross-sectional areas of the other first channels, and because the two first main channels farthest from the first plane are communicated with one first channel group and the other first main channels are communicated with two first channel groups, the flow entering each first channel group through each first channel and the corresponding first main channel can be the same as possible by controlling the cross-sectional areas of each first channel.
As shown in fig. 3, in some embodiments, the area where the first main flow channel is communicated with the first flow channel group, the area where the second main flow channel is communicated with the second flow channel group, and the area where the first flow channel group is communicated with the second flow channel group are all provided with turbulence structures.

Through setting up vortex structure, can carry out the further distribution of flow, strengthen the heat transfer effect.
In some embodiments, the first main channels are used for inputting heat exchange medium, the number of single channels included in each first channel group is even, a communication branch 511 is disposed between every two adjacent single channels included in each first channel group, and the distance from the communication branch 511 to the first area 400 is 150mm to 200mm. By arranging the communication branch 511, the flow distribution in the two flow channels can be uniform, and the heat exchange effect can be enhanced.
As shown in fig. 1 and fig. 2, the embodiment of the present application further provides a battery pack, which includes the heat exchange plate 1 in the above embodiment, and further includes a plurality of battery modules 3 attached to the heat exchange plate 1, specifically, the battery modules 3 are attached to the cover 101 of the heat exchange plate 1, the number of the battery modules 3 is the same as the number of the repeating units, and the arrangement positions of the battery modules 3 are in one-to-one correspondence with the positions of the repeating units. It should be noted that, since the battery pack includes the heat exchange plate 1 in the above embodiment, the battery pack has at least all the advantages of the above embodiment, and will not be described in detail herein.
Since the heat dissipation capacity of each repeating unit is substantially the same, the battery modules 3 are in one-to-one correspondence with the repeating units, and thus, the heat dissipation consistency of each battery module 3 can be improved. In this embodiment, the battery module 3 and the liquid collecting tank 2 are both located on the same side of the cover 101, and compared with the case where the battery module 3 and the liquid collecting tank 2 are respectively disposed on two sides of the heat exchange plate 1, the overall integration of the battery pack can be relatively improved.
The working principle of the heat exchange plate 1 provided by the utility model is that a liquid outlet pipe of an external waterway inputs heat exchange media with lower temperature into a first cavity 201 through a first connector, the heat exchange media in the first cavity 201 flow into corresponding first main channels through each first cavity, then flow into corresponding first channel groups through the first main channels, the heat exchange media flow out of the first channel groups and then flow into corresponding second main channels through corresponding second channel groups, when flowing through the first channel groups and the second channel groups, the heat exchange media have better heat dissipation effect on corresponding areas, part of heat of the corresponding areas is taken away, finally the heat exchange media of each second channel group enter a second cavity 202 through corresponding second cavities, and the heat exchange media with higher temperature flow out of the second cavity 202 to a liquid return pipe of the external waterway.
