The invention belongs to the technical field of automobile air conditioners, and particularly relates to a composite circulation type new energy automobile air conditioning system. A four-way reversing valve, an electric compressor and a two-way expansion valve are included; a gas-liquid separator is arranged between the electric compressor and a return pipe connected with the four-way reversing valve; the four-way reversing valve is connected with one end of an outdoor heat exchanger and one end of an indoor heat exchanger; the outdoor heat exchanger and the indoor heat exchanger are connected to the two-way expansion valve; a filter is connected between the four-way reversing valve and the compressor; the outdoor heat exchanger comprises an outer shell; a channel coil pipe is installed on the outer shell, and a plurality of fins are evenly installed on the outer shell in a vertical direction; a cleaning and scraping mechanism is mounted in a bottom end of the outer shell; and a plurality of clamping scraping grooves are uniformly formed in the inner side of a cleaning scraping strip, and elastic sponge strips are movably arranged in the clamping scraping grooves. Ice and frost onthe fins can be melted and removed, a dust layer can be cleaned, and efficient work of cold and heat composite circulation of the new energy automobile air conditioning system is improved.

    本发明属于汽车空调技术领域,具体的说是一种复合循环型新能源汽车空调系统;四通换向阀、电动压缩机和双向膨胀阀;电动压缩机与四通换向阀连接的回流管之间设有气液分离器四通换向阀分别与室外热换器一端和室内热换器一端连接;室外热换器和室内热换器分别连接到双向膨胀阀上;四通换向阀与压缩机之间连接有过滤器;室外热换器包括外壳体;外壳体上安装有通道盘管,且外壳体的竖直方向均匀安装有多个翅片;外壳体的底端内部安装有清理刮除机构;清理刮条的内侧均匀开设有多个卡合刮槽,且卡合刮槽内活动设置有弹性海绵条;既能够对翅片上的冰霜进行融化清除,能够对灰尘层进行清理,提高了新能源汽车空调系统的冷热复合循环的高效工作。
