A large amount of heat will be generated in the working process of the battery, if it cannot be cooled in time and effectively, it will lead to the battery temperature being too high, and then affect the battery life, performance and even safety. Therefore, the battery thermal management system (BTMS) becomes an indispensable part of the battery design, and the design and installation of the cooling pipeline are the key link of the thermal management system.

[0003] In the existing battery mounting box design, the battery box is usually composed of a box body and a box cover, and the cooling pipeline is independent of the box body or the box cover.
