[0003] In the prior art, the commonly used water-cooling heat dissipation structures are mostly series structures. The cooling water needs to flow through multiple battery cells in sequence, resulting in a long total cooling water flow. The flow rate, flow rate and cooling performance of the cooling water will become lower and lower during the circulation process, resulting in uneven heat dissipation of each battery cell.

[0007] As a further improvement of the present invention, three water-cooling vertical plates are provided.

[0008] As a further improvement of the utility model, the water inlet channel and the water outlet channel are both arranged in a ring shape on the water-cooling bottom plate.

[0012] As a further improvement of the utility model, the water inlet and the water outlet of the heat dissipation channel are respectively arranged at two ends of the heat dissipation channel.

[0013] As a further improvement of the utility model, one-way valves are respectively provided at the water inlet and the water outlet of the heat dissipation flow channel.

[0014] The beneficial effects of the present invention are as follows: in the present invention, a structure of multiple water-cooled vertical plates is adopted, so that the battery cells can be separated and independently dissipated through the water-cooled vertical plates, which can effectively improve the heat dissipation efficiency. At the same time, the heat dissipation channels of the multiple water-cooled vertical plates and the water inlet channels and outlet channels on the water-cooled bottom plate form a parallel channel structure, realizing the synchronous circulation of multiple heat dissipation channels, which can effectively reduce the flow process of water flow, reduce the loss of flow velocity, flow rate and cooling performance caused by the cooling water during the circulation process, thereby improving the heat dissipation balance of the battery cells.
