The invention relates to a waste heat recovery type battery electric vehicle heat management system which comprises a waste heat recovery module used for recovering heat of a battery and a motor and comprising a waste heat recoverer and a cooling unit used for actively refrigerating the battery. The air conditioner module sequentially comprises a compressor, a first electromagnetic valve, an inner condenser, a one-way valve, an outer heat exchanger, a third electromagnetic valve and a gas-liquid separator according to the flow direction of a medium during heating. The system not only can absorb heat from the atmosphere, but also can switch a cooling cycle working mode through the four-position five-way valve, so that the heat emitted by the motor and the battery is absorbed, and the heating effect is improved; the electronic expansion valve is used for controlling the flow proportion, the heating efficiency is improved to the maximum extent, the electronic expansion valve can further adjust the heat exchange priority, it is ensured that a battery, a motor, an electronic controller and other key parts are at the good working temperature, heat management of the whole vehicle is planned as a whole, and the comfortable environment of a passenger compartment is ensured.

    本发明涉及一种余热回收型纯电动汽车热管理系统,包括余热回收模块,其用于回收电池与电机的热量,包括余热回收器、以及用于给电池主动制冷的冷却机组;空调模块,按制热时介质流向依次包括压缩机、第一电磁阀、内冷凝器、单向阀、外换热器、第三电磁阀、气液分离器。本系统除了可以从大气中吸收热量,还可以通过四位五通阀,切换冷却循环工作模式,实现吸收电机和电池发出的热量,提高采暖效果;并通过电子膨胀阀控制流量比例,最大限度提高制热效率,电子膨胀阀还可以调节换热优先级,确保电池、电机、电控等关键零件处于良好的工作温度,统筹整车的热管理,保证乘客舱的舒适环境。
