Exhaust member, thermal management system, battery system, and electric device

Abstract

The application relates to an exhaust member, a thermal management system, a battery system and a power utilization device. The thermal management system comprises a liquid cooling unit, a liquid inlet pipe group, a liquid cooling plate, a liquid outlet pipe group, a water tank and an exhaust member which are sequentially connected to form a medium circulation loop. The water tank comprises an inner cavity, a liquid injection port and a liquid supply port which are communicated with the inner cavity. The exhaust member comprises a gas collection cavity, a liquid inlet hole, a first connecting hole, a second connecting hole and an exhaust hole. The exhaust hole is arranged higher than the liquid inlet hole, the first connecting hole and the second connecting hole. The liquid inlet hole is communicated with the liquid supply port, and the liquid supply port is arranged higher than the liquid inlet hole. The exhaust hole is arranged higher than the highest position of the medium circulation loop. The scheme can improve the liquid injection efficiency of the thermal management system and reduce the liquid injection difficulty under the condition of pure gravity.
