The invention relates to a new energy automobile thermal management system based on an R290 refrigerant, which comprises an air conditioning module adopting the R290 refrigerant as a medium, and further comprises a passenger compartment module, an external heat exchange module and a battery module, the air conditioner module sequentially comprises a compressor, a first flow channel of the first liquid heat exchanger, a liquid storage drying bottle, an electronic expansion valve and a first flow channel of the second liquid heat exchanger in the flow direction of the medium loop. According to the heat management system, R290 is adopted as a refrigerant, the R290 is only used as a medium in an air conditioner module, the adding amount of the R290 is reduced, the refrigerant is distributed in a concentrated mode, protection is convenient, heat release is conducted through a first liquid heat exchanger, heat absorption is conducted through a second liquid heat exchanger, and a passenger compartment module, an external heat exchange module and a battery module are further combined. The double-medium heat management system is achieved, R290 refrigerants with higher heat efficiency can be introduced into the automobile heat management system, all pipeline valves can serve as integrated valve modules after being optimized, and occupied space can be reduced.

    本发明涉及一种基于R290冷媒的新能源汽车热管理系统,包括采用R290冷媒作为介质的空调模块,还包括乘员舱模块、对外换热模块、电池模块,空调模块按介质回路的流向依次包括:压缩机、第一液体换热器的第一流道、储液干燥瓶、电子膨胀阀、第二液体换热器的第一流道。该热管理系统通过采用了R290作为冷媒,并且使得R290仅在空调模块中作为介质,降低其添加量,且该冷媒分布集中,方便防护,通过第一液体换热器进行放热,以及第二液体换热器进行吸热,进一步将乘员舱模块、对外换热模块、电池模块互相组合,实现了双介质热管理系统,得以将热效率更高的R290冷媒引入汽车热管理系统中,并且各个管路阀门经过优化后可以作为集成阀模块,有助于降低空间占用。
