CELL MODULE LIQUID COOLING STRUCTURE AND BATTERY PACK USING SAME

WIPO Patent Application WO/2022/021065

A1

Provided in the present application are a cell module liquid cooling structure and a battery pack using same. The cell module liquid cooling mechanism comprises a bottom cooling structure, a first side surface cooling structure, and a second side surface cooling structure that is opposite to the first side surface cooling structure; the first side surface cooling structure, the bottom cooling structure, and the second side surface cooling structure are connected in succession to form a cooling circuit; and at least one among the first side surface cooling structure, the second side surface cooling structure, and the bottom cooling structure comprises a shunting structure. The cell module liquid cooling structure provided by the present application uses a three-sided surface cooling structure, which can effectively increases the contact area and enhance the overall heat exchange efficiency of a cell module. Moreover, at least one of the first side surface cooling structure, the second side surface cooling structure, and the bottom cooling structure comprises a shunting structure. The shunting structure is a plurality of pipelines arranged side by side, and the design can effectively reduce the loss of pressure for the entire liquid cooling system.
