The invention belongs to the technical field of automobile thermal management, and particularly relates to a new energy automobile thermal management system and an automobile. The new energy automobile thermal management system comprises a heat pump air conditioner refrigerant subsystem and a cooling liquid loop subsystem; the heat pump air conditioner refrigerant subsystem comprises a compressor, a water cooling condenser, a first three-way valve, a first electronic expansion valve, an evaporator, a second electronic expansion valve, a second three-way valve, a one-way valve, a stop valve, an evaporative condenser and a third electronic expansion valve. And the cooling liquid loop subsystem comprises a water-cooling condenser loop formed by sequentially communicating a second electronic water pump, a water-cooling condenser, a second three-way water valve and a warm air heater. The problems that in the prior art, a new energy automobile needs insufficient refrigerating capacity when battery fast charging cooling and passenger compartment refrigerating are conducted at the same time at the high temperature, and the heating energy efficiency ratio of a heat pump is low at the low temperature are effectively solved, and the energy efficiency ratio and the endurance mileage of the automobile are effectively increased.

    本发明属于汽车热管理技术领域,具体涉及一种新能源汽车热管理系统及汽车,包括热泵空调制冷剂子系统和冷却液回路子系统;所述热泵空调制冷剂子系统包括压缩机、水冷冷凝器、第一三通阀、第一电子膨胀阀、蒸发器、第二电子膨胀阀、第二三通阀、单向阀、截止阀、蒸发式冷凝器和第三电子膨胀阀;所述冷却液回路子系统包括由第二电子水泵、水冷冷凝器、第二三通水阀和暖风加热器依次连通的水冷冷凝器回路。本发明有效解决了现有技术中新能源汽车高温下电池快充冷却和乘客舱制冷同时需求制冷量不足及低温下热泵制热能效比低的问题,有效提高了汽车的能效比和续航里程。
