The heat pump compressor for the new energy automobile comprises an air inlet section, a body section and an exhaust section, and an air inlet is formed in the air inlet section; the compressor is provided with an air inlet section and an air outlet section, the air outlet section is provided with an air outlet, the air outlet is connected with a condenser in the heat pump system, the compressor is provided with a hot air bypass assembly, the hot air bypass assembly comprises a mixing cavity connected with the air inlet section, the upper end of the mixing cavity is connected with an air suction port, and the air suction port is connected with an evaporator in the heat pump system; the bypass branch is connected with the exhaust section, and one end, far away from the exhaust section, of the bypass branch is connected with the mixing cavity. By arranging the mixing cavity, a gas-liquid separator in the system can be replaced; liquid entering from the air suction port is stored at the bottom of the mixing cavity due to gravity, the liquid can be prevented from directly entering the compressor to cause liquid impact, the liquid at the bottom of the mixing cavity is vaporized along with temperature rise, the liquid can enter the compressor along with air entering from the air suction port, liquid gathering is avoided, and liquid impact is further avoided.

    本发明涉及一种新能源汽车用热泵压缩机,包括进气段,本体段和排气段,所述进气段上设置有进气口;所述排气段上设置有排气口,所述排气口与热泵系统中的冷凝器连接,所述压缩机上设置有热气旁通组件,所述热气旁通组件包括:与进气段连接的混合腔,所述混合腔上端连接有吸气口,所述吸气口与热泵系统中的蒸发器连接;与排气段连接的旁通支路,所述旁通支路远离排气段的一端与混合腔连接。通过混合腔的设置,可取代系统中的气液分离器;从吸气口进入的液体部分由于重力存储在混合腔的底部,可防止液体直接进入压缩机导致液击,且随着温度升高混合腔底部的液体汽化,可随吸气口进入的气体进入压缩机,避免了液体集聚,进一步避免液击发生。
