Compressor rear shell assembly and scroll compressor comprising same

The utility model provides a compressor rear shell assembly and a scroll compressor comprising the same. The compressor rear shell assembly comprises a rear shell body and a mounting plate connected with the rear shell body in a sealed mode. The rear shell body is provided with an air suction port, an airflow channel and at least one first airflow through hole; when the rear shell assembly is used for the compressor, one side of the rear shell body is a refrigerant cavity, the other side of the rear shell body and the mounting plate form a heat dissipation cavity, and the heat dissipation cavity communicates with the air suction port through the airflow channel. The heat dissipation cavity is communicated with the refrigerant cavity through at least one first airflow through hole. The scroll compressor disclosed by the utility model has a controller cooling function, the heat dissipation surface of the controller power module is subjected to enhanced heat exchange by using a sucked low-temperature refrigerant
