In order to keep the power battery of new energy vehicles in the optimal operating temperature range dur-ing operation,a new type of cold plate with tree structure channels is proposed in this paper.The heat dissipation ability of the cold plate with different tree structure channels on the battery is analyzed by comparing the number of entrance channels,and the tree structure with better thermal performance is selected to compare with the traditional straight-through cold plate.The results show that on the tree structure,with the increase of the number of inlet channels the high temperature region of the battery is reduced,and the heat dissipation uniformity of the cold plate is also improved,which is a huge improvement of the thermal performance compared with the traditional straight-through cold plate.This heat dissipation structure can provide a certain reference for other liquid cooling structures.
