The invention relates to the field of automobile heat management, and provides an electric automobile and a heat management system thereof. A cooling liquid subsystem of the system comprises a five-way valve, a six-way valve, a PTC heating assembly, a battery cooling assembly, a motor cooling assembly, a radiator, a heat exchanger, a water-cooling condenser, a warm core, a one-way valve and a water pump, and the six-way valve is connected with the motor cooling assembly, the battery cooling assembly, the heat exchanger, the water-cooling condenser and the water pump. The five-way valve is connected with the PTC heating assembly, the motor cooling assembly, the heat exchanger, the radiator and the water pump, and a plurality of different loops of the cooling liquid subsystem are formed by switching the position states of the five-way valve and the six-way valve. Through the connection relation of the five-way valve and the six-way valve and the combination of the position state switching of the five-way valve and the six-way valve, the number of valve body assemblies can be reduced while heat transfer for refrigeration or heat dissipation can be effectively achieved, for example, the use of three-way valves with high cost can be reduced, and the system cost can be reduced.

    本申请涉及汽车热管理领域,提出了一种电动汽车及其热管理系统。该系统的冷却液子系统包括五通阀、六通阀、PTC加热组件、电池冷却组件、电机冷却组件、散热器、换热器、水冷冷凝器、暖芯、单向阀、水泵,六通阀与电机冷却组件、电池冷却组件、换热器、水冷冷凝器、水泵相连,五通阀与PTC加热组件、电机冷却组件、换热器、散热器、水泵相连,通过切换五通阀、六通阀的位态,构成冷却液子系统的多个不同的回路。通过五通阀和六通阀的连接关系,结合五通阀和六通阀的位态切换,可以有效的实现用于制冷或散热的热量输送的同时,还可以减少阀体组件的数量,比如可以减少成本较高的三通阀的使用,有利于降低系统成本。
