When the opening of the input end portion 210 is arranged as described above, the opening can be well staggered with the opening of the output end portion 310, and the refrigerant is fully flowed in the separation chamber 101, thereby realizing gas-liquid separation.

At this time, the air inlet pipe 200 and the air outlet pipe 300 can be further connected through the auxiliary member 500, so that the air inlet pipe 200 and the air outlet pipe 300 are limited with each other, and the vibration of the air inlet pipe 200 and the air outlet pipe 300 is reduced, and the auxiliary member 500 divides the first chamber 102 into the first sub-chamber 102a and the second sub-chamber 102b, and the output end portion 310 is located in the first sub-chamber 102a, and the input end portion 210 is located in the second sub-chamber 102b, so that when the input end portion 210 conveys the refrigerant into the separation chamber 101, part of the refrigerant can be prevented from directly entering the output end portion 310 without gas-liquid separation, the liquid entering the output end portion 310 is reduced, and the gas-liquid separation effect can be improved.

At this time, the flow direction of the refrigerant is changed before the refrigerant enters the separation chamber 101, so that the effect of reducing the flow velocity can be achieved, and the impact on the shell 100 and the outlet pipe 300 is reduced.

Alternatively, the introduction part 220 is disposed in a vertical direction, the input end part 210 is disposed toward the sidewall 101b of the separation chamber 101, and the connection between the introduction part 220 and the input end part 210 has an arc structure.

Or the number of third pipe sections is plural.

In one embodiment, as shown in fig. 1 and fig. 2, the flow buffering member 400 is provided with a plurality of through holes 401.
