Description

Technical Field

[0002] Automobile compressor plays a vital role in automobile air-conditioning system, which mainly involves the compression and circulation of gas. Its performance directly affects the cooling effect and energy consumption of air-conditioning. With the rapid development of automobile industry and the increasing requirements of people for automobile comfort, the performance of automobile air-conditioning system has also been significantly improved.

[0003] The gas flow direction of the original compressor is from the suction hole of the rear cover to the suction chamber, and the suction chamber passes through a number of rectangular channels to the inner cavity of the compressor. Due to the limited cross-sectional area of ​​the rectangular channels, the flow rate sucked into the inner cavity of the compressor is insufficient, which will lead to a decrease in the refrigeration capacity of the compressor and insufficient energy efficiency. At the same time, due to the large pulsation of the air flow and the instability of the flow, the operating pulsation and noise of the compressor are relatively large. Therefore, an air flow flow structure for an automobile air-conditioning compressor is proposed. Utility Model Content
