The invention belongs to the technical field of electric vehicle thermal management, and particularly relates to a whole vehicle thermal management system of a pure electric vehicle. Wherein the radiator is connected with a pipe orifice C of the first four-way valve, the radiator is connected with the motor system, the motor system is connected with the motor water pump, the motor water pump is connected with a pipe orifice B of the first four-way valve and a pipe orifice E of the second four-way valve, and the motor system is further connected with a pipe orifice A of the first four-way valve. The intermediate heat exchanger is connected with a first four-way valve D pipe orifice and a second four-way valve G pipe orifice, the intermediate heat exchanger is respectively connected with a battery water pump and a second four-way valve F pipe orifice, the battery water pump is connected with a high-voltage electric heater, the high-voltage electric heater is connected with a battery system, and the battery system is connected with a second four-way valve H pipe orifice; the motor can independently provide heat for the intermediate heat exchanger, it is guaranteed that the temperature of the battery is not reduced, meanwhile, waste heat of the motor is completely provided for the passenger compartment, energy loss is avoided, and therefore the endurance mileage of the whole vehicle is increased.

    本发明属于电动车热管理技术领域,具体涉及一种纯电动汽车的整车热管理系统;其中散热器与第一四通阀C号管口连接,散热器与电机系统连接,电机系统与电机水泵连接,电机水泵与第一四通阀B号管口和第二四通阀的E号管口连接,电机系统还与第一四通阀A号管口连接,中间换热器与第一四通阀D号管口和第二四通阀G号管口连接,中间换热器分别与电池水泵和第二四通阀F号管口连接,电池水泵与高压电热器连接,高压电热器与电池系统连接,电池系统与第二四通阀H号管口连接;本发明能够实现电机单独给中间换热器提供热量,保证电池温度不降低的同时,将电机余热全部提供给乘员舱,避免能量损失,从而提升整车续航里程。
