Claim 19:
20. An air conditioning system, comprising:
a heat exchanger;
a compressor connected with the heat exchanger by pipelines; and
a gas-liquid separator connected between the heat exchanger and the compressor;
the gas-liquid separator further comprising:
a first cylinder;
a second cylinder surrounded around the first cylinder at a predetermined distance, an interlayer space being formed between the first cylinder and the second cylinder; and
a heat exchange assembly, the heat exchange assembly being disposed in the interlayer space, the heat exchange assembly comprising a first collecting pipe, a second collecting pipe disposed in parallel to the first collecting pipe, a flat tube disposed in the interlayer space and connected between the first collecting pipe and the second collecting pipe, and a heat dissipation member being in contact with the flat tube and at least one of the first cylinder and the second cylinder, the first collecting pipe having a first internal cavity, a refrigerant inlet and a refrigerant outlet the second collecting pipe having a second internal cavity; the flat tube have a plurality of channels communicating the first internal cavity and the second internal cavity; and an extension direction of the first collecting pipe being parallel to an axial direction of the first cylinder; wherein
at least a part of a side wall surface of the first cylinder is formed with an avoidance portion recessed inwardly, the avoidance portion defines a receiving space communicating with the interlayer space, the first collecting pipe and the second collecting pipe are disposed adjacent to each other, and at least part of the first collecting pipe and at least part of the second collecting pipe are disposed in the receiving space;
wherein the first collecting pipe is longer than the second collecting pipe along the extension direction in a manner that the refrigerant inlet is disposed at a position lower than a bottom end of the second collecting pipe, and the refrigerant outlet is disposed at a position higher than a top end of the second collecting pipe;
wherein the refrigerant inlet communicates with an outlet of the heat exchanger, and an outlet of the interlayer space between the first cylinder and the second cylinder communicates with an inlet of the compressor.
