[0002] The new energy industry is injecting new impetus into the economy and creating new development opportunities. The cooling system composed of cooling plates in new energy battery modules is of utmost importance. Due to the frequent heating and spontaneous combustion of new energy battery modules, the cooling system composed of cooling plates is a necessary means to cool the heat.

[0003] Most of the commonly used liquid cooling plates currently use a single-channel flow channel structure. As the coolant flows in the flow channel, the coolant temperature gradually increases, and the corresponding cooling effect gradually decreases. The coolant with a lower temperature is distributed on the side close to the liquid inlet, and the coolant with a higher temperature is distributed on the side close to the liquid outlet, resulting in a large temperature difference between the left and right sides of the liquid cooling plate. The side with a higher temperature of the liquid cooling plate is prone to deformation, resulting in a gap between the battery module, which further deteriorates the heat dissipation effect and creates a vicious cycle.
