The motor is similar to the power battery cooling system in aspect, and is cooled by adopting a liquid cooling mode. The difference is that the power battery system uses water as cooling medium, and the motor cooling medium is changed into water-glycol mixed solution, and the cooling medium is indirectly cooled by convection heat exchange through the cooling water jacket on the outer wall surface of the motor stator. Therefore, when the power battery system uses water as a cooling medium, the requirements on a liquid cooling plate which is used for containing the cooling medium and changes along with the battery are more strict, and the liquid cooling has the characteristics of high cooling speed, large specific volume and high heat exchange coefficient, is adopted by BMW, tesla and the like, and gradually becomes a main flow path; the liquid collecting tank is additionally provided with one piece of spacer, so that whether welding is complete or not and whether series flow phenomenon occurs can be detected more quickly. And the sealing performance of the battery and the components thereof can reach the IP67 standard according to the national standard GB 38031-2020.

The existing liquid cooling plate liquid collecting tank only has one spacer, so that whether welding is complete or not can not be detected rapidly, and whether series flow phenomenon occurs in the liquid cooling plate liquid collecting tank can not be detected in the using process.
