Claim 0:
1. A gas-liquid separator, 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 arranged between the first cylinder and the second cylinder, the heat exchange assembly comprising a collecting pipe, a flat tube disposed in the interlayer space, and a heat dissipation member; the collecting pipe comprising a first collecting pipe and a second collecting pipe disposed in parallel to the first collecting pipe; the first collecting pipe defining a first chamber, a refrigerant inlet communicating with the first chamber, a second chamber, a refrigerant outlet communicating with the second chamber, and a separator separating the first chamber from the second chamber; the second collecting pipe defining a third chamber and a fourth chamber communicating with the third chamber; the flat tube being connected between the first collecting pipe and the second collecting pipe; the flat tube comprising a first C-shaped portion communicating the first chamber and the third chamber and a second C-shaped portion communicating the second chamber and the fourth chamber; the heat dissipation member residing in the interlayer space; the heat dissipation member being in contact with the flat tube and at least one of the first cylinder and the second cylinder; 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; and
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.
