The container is used to store liquid refrigerant. The inlet and outlet of the gas-liquid separator are arranged at one end of the container. The inlet is connected to the interior of the body, the air inlet port of the air duct is connected to the interior of the container, and the air outlet port of the air duct is connected to the outlet. When working, the inlet and outlet of the gas-liquid separator are installed upward in the automobile air conditioning system, and the gas and liquid refrigerants flow in from the inlet.

[0030] like Figures 1 to 6 As shown, a gas-liquid separator structure includes a shell 1, a head 2 is fixed on the shell 1, an inlet 2a and an outlet 2b are arranged on the head 2, a bulk liquid cup 3 is arranged below the inlet 2a in the shell 1, an air guide pipe 4 is fixed in the shell 1, the air outlet of the air guide pipe 4 is connected to the outlet 2b, the air guide pipe 4 includes a first straight pipe section 41 and a second straight pipe section 42, and a connector 43 is arranged between the first straight pipe section 41 and the second straight pipe section 42.

[0031] The function of the bulk liquid cup 3 is that after the mixed gas-liquid two-phase refrigeration air is taken in, the gas and liquid are separated through the bulk liquid cup 3, and the liquid settles to the bottom of the gas-liquid separator by gravity.

[0032] The connector 43 includes a tube sleeve 431 and a bottom cover 432 . A liquid accumulation plate 433 is disposed between the tube sleeve 431 and the bottom cover 432 . A liquid leakage hole 433 a is disposed on the liquid accumulation plate 433 .

[0033] The inner periphery of the bottom cover 432 is provided with a limiting portion 432a.

[0034] The limiting portion 432 a is in the form of an annular structure that matches the liquid accumulation plate 433 .

[0035] The upper end of the bottom cover 432 is provided with a rim 432 b , and the rim 432 b covers the outer periphery of the effusion plate 433 and the outer periphery of the lower end of the tube sleeve 431 .

[0036] The middle part of the liquid accumulation plate 433 is concave, and the leakage hole 433a is set at the center of the concave part. When the liquid accumulation plate 433 is assembled into the bottom cover 432, the outer periphery of the liquid accumulation plate 433 is supported on the limiting part 432a of the bottom cover 432, and a cavity is formed between the bottom surface of the liquid accumulation plate 433 and the inner bottom surface of the bottom cover 432. The setting of the pipe sleeve 431 facilitates the connection between the first straight pipe section 41, the second straight pipe section 42 and the connector 43. The setting of the edging 432b can improve the reliability of the assembled structure and prevent the liquid accumulation plate 433 from shifting.

[0037] One end of the air guide tube 4 is connected to the bulk liquid cup 3 , and an air inlet 4 a is formed between the air guide tube 4 and the bulk liquid cup 3 .

[0038] A molecular sieve bag 5 is arranged in the housing 1 .

[0039] The molecular sieve bag 5 is coated on the outside of the air guide tube 4 .

[0040] The molecular sieve bag 5 is used to filter and dry the refrigerant in the gas-liquid separator, absorb impurities and moisture therein, and ensure the quality of the oil entering the compressor. In this embodiment, the molecular sieve bag 5 is U-shaped and wrapped around the first straight pipe section 41 and the second straight pipe section 42 of the air guide pipe 4.

[0041] The outer circumference of the bulk liquid cup 3 is in an arc-shaped structure.

[0042] Working principle:

[0043] The mixed refrigerant of gas and liquid flows in from the inlet 2a of the end cap 2. Due to the obstruction of the bulk cup 3, the refrigerant cannot directly enter the air guide tube 4, but flows along the surface of the bulk cup 3 to the surroundings of the bulk cup 3. The liquid refrigerant settles to the bottom of the gas-liquid separator under the action of gravity. The gaseous refrigerant enters the air guide tube 4 from the air inlet 4a of the air guide tube 4, and finally flows out from the outlet 2b of the gas-liquid separator, thereby achieving the purpose of gas-liquid separation. A small amount of water may be mixed in the gaseous refrigerant. When the gaseous refrigerant flows through the air guide tube 4, the air guide tube 4 is in a U-shaped structure. The water is deposited at the connector 43 at the bottom end of the air guide tube 4, and enters the volume of the bottom cover 432 through the leakage hole 433a of the liquid accumulation plate 433.

[0044] The utility model provides a gas-liquid separator structure, wherein the air guide pipe 4 adopts a segmented structure, that is, the air guide pipe 4 includes a first straight pipe section 41, a second straight pipe section 42 and a connector 43. The first straight pipe section 41 and the second straight pipe section 42 are easy to obtain and process. When producing gas-liquid separators of different models (different volumes), the connector 43 can be shared by gas-liquid separators of various models. It is only necessary to cut straight pipe sections of different lengths according to different models, which can greatly save production costs and improve production efficiency.

[0045] The above are only preferred embodiments of the present invention, and do not limit the implementation mode and protection scope of the present invention. Those skilled in the art should be aware that all solutions obtained by equivalent substitutions and obvious changes made using the description and illustrations of the present invention should be included in the protection scope of the present invention.
