The invention relates to a water loop heat pump type electric automobile heat management system based on phase change heat storage, which adopts a mode of coupling a phase change heat storage technology and a water loop heat pump technology. An output end of a power assembly heat dissipation subsystem is connected to an input end of a proportional three-way valve, a first output end of the proportional three-way valve is connected to an input end of a phase change heat storage device, a second output end is connected to an input end of a second electromagnetic valve, and an output end of the phase change heat storage device is connected to the input end of the second electromagnetic valve. Compared with the prior art, waste heat generated by the system can be efficiently recovered, the waste heat is released at a proper time, and the difference of quantity, form and time of energy in supply and demand is overcome. A phase change heat storage unit is additionally arranged, so that efficient heating at low temperature can be achieved, the problems of frosting, low heat efficiency, even running failure and the like caused by using an air source heat pump at low temperature are solved, efficient cooling at high temperature can be achieved, and therefore the area of a front-end radiator is reduced, wind resistance is reduced, and the endurance mileage is increased.

    本发明涉及一种基于相变蓄热的水环热泵型电动汽车热管理系统,采用相变蓄热技术和水环热泵技术耦合的方式,动力总成散热子系统的输出端连接至比例三通阀的输入端,比例三通阀的第一输出端连接至相变蓄热器的输入端,第二输出端连接至第二电磁阀的输入端,相变蓄热器的输出端连接至第二电磁阀的输入端。与现有技术相比,本发明可以高效回收系统产生的余热,并在合适的时候释放余热,克服能量在供需上存在的数量、形态和时间的差异。相变蓄热单元的增设不仅可以实现低温下高效制热,避免在低温下使用空气源热泵造成的结霜、热效率低、甚至无法运行等问题,还可以实现高温下高效冷却,从而减小前端散热器面积、降低风阻、提高续航里程。
