本发明公开了一种基于二次换热的客车整车热管理机组,包括冷媒压缩回路和二次换热回路,所述冷媒压缩回路包括压缩机、第一换热器、第一膨胀阀和第二换热器;所述二次换热回路包括与第一换热器和第二换热器进行热交换的载冷剂及其管路,以及使经过热交换的载冷剂循环流动的散热装置。本发明提供的基于二次换热的客车整车热管理机组与传统客车空调相比,具有更强的扩展性、更高的兼容性和更高的集成性,系统中可以按需要增加或减少相应接口以实现电池冷却、余热利用,接入壁挂散热器、除霜器、踏步散热器、司机取暖器等零部件,最终实现整车的热管理;因其二次换热的特点,系统还可以使用R744/R290/R32等具有一定安全风险的制冷剂。

    The invention discloses a passenger car whole vehicle thermal management unit based on secondary heat exchange, which comprises a refrigerant compression loop and a secondary heat exchange loop, and is characterized in that the refrigerant compression loop comprises a compressor, a first heat exchanger, a first expansion valve and a second heat exchanger; and the secondary heat exchange loop comprises a secondary refrigerant for exchanging heat with the first heat exchanger and the second heat exchanger, a pipeline of the secondary refrigerant, and a heat dissipation device for enabling the secondary refrigerant subjected to heat exchange to circularly flow. Compared with a traditional passenger car air conditioner, the whole passenger car thermal management unit based on secondary heat exchange has the advantages of stronger expansibility, higher compatibility and higher integration, corresponding interfaces can be increased or decreased as required to realize battery cooling and waste heat utilization in the system, parts such as a wall-mounted radiator, a defroster, a stepping radiator and a driver warmer are connected, and finally thermal management of the whole passenger car is realized. Due to the characteristic of secondary heat exchange, refrigerants such as R744/R290/R32 and the like with certain safety risks can be used in the system.
