The invention provides an air source heat pump type electric vehicle heat management system based on phase change heat storage. Full working condition requirements of five temperature working conditions and three driving working conditions can be met only by controlling eight simple valves. A phase change heat storage module is additionally arranged in a power assembly heat management subsystem, waste heat generated by all parts in the system can be efficiently recycled, the waste heat is released at the proper time, the difference of energy in quantity, form and time in supply and demand is overcome, and efficient heating and refrigerating can be achieved. An air source heat pump manner is adopted, a low-temperature heat source is provided by an air source, system waste heat and a small amount of electric energy, the requirements of different low-temperature working conditions can be met, and the energy utilization efficiency is effectively improved. Three subsystems are organically integrated, the valve control operability is high, the structure of component parts is compact, and the integration degree is high; and the phase change heat storage module is additionally arranged, so that the area of a front-end radiator can be reduced, the windward area can be reduced, wind resistance can be reduced, and the endurance mileage can be increased.
本发明提供一种基于相变蓄热的空气源热泵型电动汽车热管理系统,仅通过控制八个简单阀门,即可以满足五个温度工况及三个行驶工况的全工况需求。本发明在动力总成热管理子系统内增设了相变蓄热模块,可以高效回收系统中各部件产生的余热,并在合适的时候释放余热,克服了能量在供需上存在的数量、形态和时间的差异,可以实现高效制热及制冷。采用空气源热泵的方式,由空气源、系统余热、少量电能提供低温热源,可以实现不同低温工况的需求,并有效提高能源利用效率。本发明将三个子系统进行有机整合,阀门控制可操作性强、组成部件结构紧凑、集成度高;其中,相变蓄热模块的增设可以减小前端散热器面积,从而可以减小迎风面积、降低风阻、提高续航里程。
