The invention discloses an R290 finished automobile thermal management system and method for a new energy automobile. A refrigerant outlet of a battery cooler is communicated with a refrigerant inlet of an electric compressor, a refrigerant outlet of the electric compressor is communicated with a refrigerant inlet of a water-cooling condenser, and a refrigerant outlet of the water-cooling condenser is communicated with a refrigerant inlet of a liquid storage tank. A refrigerant outlet of the liquid storage tank is communicated with a refrigerant inlet of the battery cooler, and an electronic expansion valve is arranged at the refrigerant inlet of the battery cooler. The R290 thermal management system is adopted, the thermal performance is good, the low-temperature heating capacity is high, and attenuation of the low-temperature endurance mileage is reduced; according to the invention, the refrigerant loop is optimized, the minimum refrigerant charge is realized, and the system safety is ensured; the refrigerant loop is isolated from the passenger compartment, and the system safety is further guaranteed.

    本发明公开了一种用于新能源汽车的R290整车热管理系统及方法。本发明中电池冷却器的制冷剂出口与电动压缩机的制冷剂入口连通,电动压缩机的制冷剂出口与水冷冷凝器的制冷剂入口连通,水冷冷凝器的制冷剂出口与储液罐的制冷剂入口连通,储液罐的制冷剂出口与电池冷却器的制冷剂入口连通,且电池冷却器的制冷剂入口处设有电子膨胀阀。本发明采用了R290热管理系统,热力特性良好,低温制热能力较强,降低了低温续航里程的衰减;本发明优化了冷媒回路,实现了制冷剂充注量的最小化,保证了系统安全;本发明将冷媒回路与乘员舱隔绝开,进一步保证了系统安全。
