Referring again to fig. 1 to 8, as can be seen from the above embodiments, the vapor-liquid separator of the present application mainly comprises the following 8 parts: a housing 10; a swash plate 20; an outlet duct 40; a mounting plate located outside the housing 10; a fixing plate 60; a support tube 30; a filter 50. The main structure and the characteristics thereof are as follows: the shell 10 is provided with an end cover 12, the end cover 12 is provided with an inlet 122 and an outlet 121 which are matched and sealed with an external pipeline environment-friendly joint, the whole is in a two-stage step, and the small end part is mainly matched with the shell 10; the corner of the wave-preventing plate 20 is provided with a slope (similar to chamfer) of about 45 degrees, so that the gas from the inlet 122 is ensured to have a certain blocking effect and flow smoothly, and the pressure drop is not excessive; the support tube 30 is a cylindrical structure, 4 positioning ribs 32 are arranged at the bottom of the inner wall to position the air outlet tube 40 in the support tube 30 through interference fit, an oil return hole 311 is arranged at the bottom, a rounded arc surface structure is arranged on the upper surface of the support tube 30, the air flow field is smoother, and in order to avoid overlarge pressure difference between air inlet and air outlet, the ratio of the sectional area S1 of the flow guide gap 70 between the support tube 30 and the air outlet tube 40 to the inner diameter sectional area S2 of the air outlet tube 40 is about 2.2 to 3.0, namely S1/S2=2.2 to 3.
Compared with the existing vapor-liquid separator, the structure is optimized as follows: the traditional U-shaped air outlet pipe is changed into the air outlet pipe 40 and the support pipe 30, the lower part of the support pipe 30 is connected with the annular bracket of the filter 50 to directly contact with the bottom of the shell 10, so that the vibration resistance of a pipeline at the position is improved, and meanwhile, the support pipe 30 is connected with the shell 10 by adding the fixing plate 60 outside the support pipe 30, so that the vibration resistance of the pipeline is further improved, and the use requirement of an automobile is met.

In operation, gas enters the vapor-liquid separator through the inlet 122 of the vapor-liquid separator, first the gas impinges on the swash plate 20 to remove some liquid, and then the gas flows out through the flow gap 70 between the support tube 30 and the outlet tube 40, and returns to the compressor. The lower end of the swash plate 20 is lower than the upper surface of the support pipe 30, ensuring that liquid can be blocked by the swash plate 20 when the vapor-liquid separator is shaken by the automobile.
The assembling flow of the vapor-liquid separator is as follows: firstly, the air outlet pipe 40, the support pipe 30, the filter 50 and the fixing plate 60 are assembled into a whole through interference fit (as shown in fig. 7), then the outer flange 41 of the air outlet pipe 40 in the integrated structure pushes the wave-proof plate 20 against the lower surface of the end cover 12, the wave-proof plate is fastened through press riveting to form a component, and finally the component and the shell 10 are assembled into a whole through argon arc welding (as shown in fig. 1).

the application changes the former U-shaped air outlet pipe into the form of the air outlet pipe and the supporting pipe, and has the function of vapor-liquid separation. The vibration resistance is enhanced through the change of the structural form of the air outlet pipe, and is better than the prior U-shaped pipe. The air inlet pipe is omitted, and the wave-proof plate with inclination is added, so that liquid is prevented from directly flowing into and out of the air pipe, and the situation of liquid carrying during air suction is avoided.
The application optimizes the structures of the pipelines and the wave-proof plates in the vapor-liquid separator, improves the vibration resistance of the vapor-liquid separator, and meets the vibration requirements of an air conditioning system using a high-pressure refrigerant and an automobile. Simultaneously, the structure is more convenient to install, the welding of pipelines is reduced, and the reduction of the mechanical property of the shell caused by high-temperature electric welding is avoided.
The above is only a preferred embodiment of the present application, and is not intended to limit the present application, but various modifications and variations can be made to the present application by those skilled in the art. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application should be included in the protection scope of the present application.
