Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Referring to fig. 1 to 6, an embodiment of the present invention provides a gas-liquid separator, which includes a container, a gas-guide tube 4 and a filtering component 3; the container is of a sealed cylindrical structure, the container is provided with an inlet 11 and an outlet 12, the inlet 11 and the outlet 12 are located at the same end of the container, the inlet 11 is communicated with the interior of the container and used for introducing a gas-liquid two-phase refrigerant into the container, and the outlet 12 is used for discharging a gas-phase refrigerant; the air duct 4 is preferably a U-shaped tube, the two ends of the air duct 4 are an air inlet end portion 41 and an air outlet end portion respectively, the air inlet end portion 41 is provided with an air inlet port 411, the air outlet end portion is provided with an air outlet port 42, the air inlet port 41 is communicated with the interior of the container, and the air outlet port 42 of the air duct 4 is communicated with the outlet 12 of the container in a sealing manner; the filter component 3 is arranged in the container, the filter component 3 is provided with a through hole 31, the filter component 3 is communicated with the inside of the container, the air guide pipe 4 penetrates through the through hole 31, the air inlet end part 41 of the air guide pipe 4 is positioned in the filter component 3, the filter component 3 is communicated with the air inlet port 411, and the air guide pipe 4 is fixed relative to the filter component 3.
As shown in fig. 2, when the gas-liquid separator works, a gas-liquid refrigerant enters the container through the inlet 11, a liquid refrigerant falls into the bottom of the container under the action of gravity, while a gas-phase refrigerant enters the inlet port 411 of the gas guide tube 4 from the inside of the container, is filtered by the filtering part 3 outside the inlet end part 41 of the gas guide tube 4, and finally is discharged through the outlet port 42 of the gas guide tube 4 and the outlet 12 of the container, so that gas-liquid separation is realized. Because the filtering component 3 covers the periphery of the air inlet end part 41 of the air guide pipe 4 to filter the gas-phase refrigerant entering the air guide pipe 4, the structure of the filtering component 3 has larger inner diameter relative to the air guide pipe 4, and the filtering area for filtering the gas-phase refrigerant can be relatively increased, thereby better filtering the gas-phase refrigerant, improving the filtering capacity and the cleanliness of a gas-liquid separator, reducing the possibility of blockage of the whole automobile air conditioning system and improving the stability of the system.
Further, in this embodiment, the gas-liquid separator further includes a liquid dispersion cup 2, the liquid dispersion cup 2 is a hood-shaped structure, the liquid dispersion cup 2 is disposed below the inlet 11 and is covered above the air inlet end 41 of the air duct 4, and the air inlet end 41 of the air duct 4 abuts against the liquid dispersion cup 2.

So set up, when the gas-liquid two-phase refrigerant got into inside the container through import 11, because the liquid dispersion cup 2 keeps off between the inlet end 41 of import 11 and air duct 4, consequently, liquid refrigerant falls on liquid dispersion cup 2 earlier to dispersion all around, avoided liquid refrigerant directly to fall into in the inlet port 411 of air duct 4, thereby further improved gas-liquid separation's effect. Of course, the liquid dispersion cup 2 may not be provided, and the inlet 11 and the air inlet 411 of the air duct 4 may be arranged in a staggered manner, so as to prevent the liquid medium from directly falling into the air duct 4. The gas-phase refrigerant passes through the filter screen before entering the air inlet port 411 of the air duct 4, so that the separated gas-phase refrigerant is filtered. The filtering area of the filtering net cover structure is large, so that the filtering area is increased while the air inflow is increased.
Of course, the filtering component 3 may also be a filter plug arranged inside the air inlet end portion 41 of the air duct 4, and the gas-phase refrigerant entering the air duct 4 can be filtered in the same way. But compare in filtering the screen panel structure, the filter area of filtering the stopper is little, and the filter effect is not as good as the filter effect of filtering the screen panel.
Further, as for the filter member 3 using a filter mesh cover, the filter mesh cover is fixed to the liquid dispersion cup 2. Because the filter screen covers the periphery of the air inlet end part 41 of the air duct 4, the filter screen and the liquid dispersion cup 2 are fixed together, and only one of the filter screen and the liquid dispersion cup needs to be fixed in the container, so that the fixation of other parts in the container can be realized, and the fixation is more convenient.
