Battery pack shell with liquid cooling system

Abstract

The invention provides a battery pack shell with a liquid cooling system, and relates to the technical field of motor shell equipment. A battery pack shell with a liquid cooling system comprises a battery pack shell body, a plurality of cooling liquid storage cavities are formed in the side wall of the battery pack shell body, every two adjacent cooling liquid storage cavities are communicated through a connecting channel, a plurality of negative pressure cavities are formed in the side wall of the battery pack shell body, and the negative pressure cavities are communicated with the cooling liquid storage cavities. One ends of the plurality of negative pressure cavities are communicated with the nearest connecting channel, the other ends of the plurality of negative pressure cavities are communicated with the interior of the battery pack shell body, and negative pressure sliding plates are arranged in the plurality of negative pressure cavities. And the cooling liquid filled in the plurality of cooling liquid storage cavities and the connecting channels can also adsorb heat generated in the working process of the battery, so that a cooling effect is achieved, and normal and efficient working of the battery is ensured.
