Abstract

The invention provides a liquid cooling module and an electric vehicle. The liquid cooling module comprises a liquid cooling cavity having a receiving chamber; an liquid inlet pipe disposed on the lower portion of a bracket and communicating with the receiving chamber of the liquid cooling cavity; an liquid outlet pipe disposed on the lower portion of the bracket and communicating with the receiving chamber of the liquid cooling cavity; a coolant flowing from the liquid inlet pipe, received in the receiving chamber of the liquid cooling cavity, and flowing out from the liquid outlet pipe; anda battery module disposed in the receiving chamber of the liquid cooling cavity and immersed in the coolant. The liquid cooling module can improve the heat dissipation efficiency of a battery cell ofthe battery module, and balances the temperature of the battery core in the battery module.

Description

technical field [0001] The invention relates to the technical field of battery cooling, in particular to a liquid cooling module and an electric vehicle. Background technique [0002] With the increasing requirements of users for electric vehicles, the requirements for the power characteristics and fast charging performance of the power battery system of the whole vehicle are getting higher and higher, which is accompanied by the improvement of the thermal management design requirements of the battery system, and the temperature between the batteries. Equalization and temperature control are getting finer. [0003] At present, the thermal management of new energy vehicles mostly adopts air-cooling and liquid-cooling systems. Air-cooling is difficult to solve the heat dissipation requirements and temperature uniformity problems under high-rate charging and discharging conditions. Therefore, liquid cooling methods have increasingly become the focus of engineers. More and more...
