The automobile air-conditioning compressor is the core component. The automobile air-conditioning compressor usually uses a swash plate rotary piston for compression. According to the movement mode of the piston transmission parts, it is divided into two types: the swing swash plate type and the slewing swash plate type. Advantages and disadvantages, the mechanical balance of the swash plate type is not as good as that of the swash plate type, and the displacement is not as good as that of the swash plate type under the same shape and size; because the working gas is on both sides of the compressor, the resistance of the refrigerant channel is greater than that of the swash plate type The swash plate type, and the sliding performance of the steel ball and sliding shoe device is not as good as that of the swaying swash plate type ball joint device, and the wear and tear between the sliding shoe and the swash plate is relatively easy; and the swash plate assembly undergoes rapid offset vibration while running at high speed , the stability requirements of the supporting parts are higher, otherwise it is easy to cause poor sealing and reduce the cooling effect; the uniform distribution of air-conditioning refrigerant is also the main factor affecting the heat exchange efficiency of air-conditioning. In the prior art, the refrigerant of the air-conditioning Copper pipes are input to many horizontal heat exchange tubes installed in the heat exchanger. Due to the effect of gravity, after the refrigerant enters the heat exchange tubes, it is easy to produce more refrigerant in the heat exchange tubes in the lower part of the heat exchanger, while the heat exchange tubes in the upper part are more refrigerant. The stratification phenomenon of less refrigerant in the tube will lead to a very low utilization rate of the heat exchange tube in the upper part of the heat exchanger, resulting in a relatively low overall heat exchange efficiency of the heat exchanger

At the same time, the stratification phenomenon will also cause the superheat degree of the upper heat exchanger of the heat exchanger to be relatively high, and the superheat degree of the lower heat exchange tube to be relatively low, so that the overall superheat degree of the heat exchanger is difficult to control
