[0019] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

[0020] A cooling circulation device, such as Figure 1 , includes a main board 1, a liquid inlet pipe 2, and a liquid outlet pipe 3.

[0021] The main board 1 is internally provided with a cavity, and the cavity forms a cooling pipeline 11. Specifically, in this embodiment, the cooling pipeline 11 is bent multiple times to form a loop to improve the heat dissipation efficiency. The cooling pipeline 11 extends to the side surface of the main board 1 to form two openings for the inflow and outflow of the coolant. The outer surface of the cavity protrudes from the surface of the main board 1, and the cross-section of the cavity is a cuboid, which is convenient for processing, beneficial to contact with the battery cell 4, and also beneficial to separating the battery cells 4.

[0022] The main board 1 is made of an insulating and waterproof plastic material, and the waterproof level of the main board 1 reaches IP67. The main board 1 is rectangular, and the size of the main board 1 matches the size of the battery cell 4. In this embodiment, the battery cell 4 is a 280AH battery cell.

[0023] The liquid inlet pipe 2 and the liquid outlet pipe 3 are communicated with the two openings of the main board 1, and the coolant can enter the cooling pipeline 11 through the liquid inlet pipe 2 and then flow out from the liquid outlet pipe 3

[0024] A battery cell cooling structure, such as Figure 2 , includes a battery cell 4 and a cooling circulation device.

[0025] The battery cell cooling structure includes at least two battery cells 4. The cooling circulation device is arranged between the two battery cells 4. Both sides of the convex main board 1 are attached to the battery cells 4 through adhesive. The coolant can enter the cooling pipeline 11 through the liquid inlet pipe 2 and then flow out through the liquid outlet pipe 3 to cool the battery cells 4.

[0026] The working principle of the present utility model: The cooling circulation device is arranged between the two battery cells 4, and the main board 1 is attached to the two battery cells 4, playing a blocking role and a heat transfer role. When the battery cells 4 generate heat, the coolant flowing through the cooling pipeline 11 can take away the heat to prevent the temperature of the battery cells 4 from being too high.

[0027] The beneficial effect of the present utility model lies in that by installing the cooling circulation device between the battery cells 4, it not only plays a blocking role but also can effectively cool and lower the temperature of the battery cells 4 through the cooling pipeline 11.

[0028] The above embodiments only represent one implementation mode of the present utility model, but it should not be construed as a limitation to the scope of the utility model patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present utility model, several deformations and improvements can be made. These are all equivalent modifications and evolutions based on the essence of the present utility model to the above embodiments, and these all belong to the protection scope of the present utility model.
