Abstract
A gas-liquid separator includes a first cylinder, a second cylinder and a heat exchange assembly. The first cylinder is surrounded by the second cylinder at a predetermined distance. The heat exchange assembly is arranged between the first cylinder and the second cylinder. The heat exchange assembly includes a collecting pipe. An extension direction of the collecting pipe is parallel to an axial direction of the first cylinder. At least a part of a side wall surface of the first cylinder is formed with an avoidance portion recessed inwardly. At least a part of the collecting pipe is arranged between the avoidance portion and the second cylinder.
