The invention discloses an integrated heat pump heat management system for a pure electric vehicle. The integrated heat pump heat management system comprises a refrigerant loop and a cooling liquid loop which are used for cooling, heating or preserving heat of a battery module of the pure electric vehicle; the refrigerant loop comprises a compressor, a cabin external heat exchanger, a cabin internal heat exchanger, a first PTC heater, an ejector, a gas-liquid separator, a chiller heat exchanger and a direct cooling plate mounted at one end of the battery module; the cooling liquid loop comprises a first water pump, a chiller heat exchanger, a liquid cooling plate installed at the end, away from the direct cooling plate, of the battery module, a motor, an electric control water jacket, a radiator and a second water pump. Refrigerant and cooling liquid double loops are adopted for simultaneous cooling or heating, rapid cooling or heating of the battery module is achieved, the air suction pressure of the compressor is improved through the ejector, and the energy efficiency of the heat pump system at the low temperature is improved.

    本发明公开了一种纯电动汽车集成式热泵热管理系统,包括对纯电动汽车电池模组进行冷却、加热或保温处理的制冷剂回路和冷却液回路;所述制冷剂回路包括压缩机、舱室外部换热器、舱室内部换热器、第一PTC加热器、喷射器、气液分离器、chiller换热器和安装在所述电池模组一端的直冷板,所述冷却液回路包括第一水泵、chiller换热器、安装在所述电池模组远离所述直冷板一端的液冷板、电机及电控水套、散热器和第二水泵。本发明采用制冷剂、冷却液双回路同时冷却或加热,实现快速冷却或加热电池模组,并且通过喷射器提高压缩机吸气压力,提高低温下热泵系统的能效。
