Abstract:
A heat exchanger is disclosed. The heat exchanger comprises a first collecting pipe, a second collecting pipe, a plurality of heat exchange pipes, a plurality of fins, and a first member. A first channel comprises a first sub-channel, a second sub-channel, a third sub-channel, and a fourth sub-channel, the first sub-channel is located on the right side of the first member, and the second sub-channel is located on the left side of the first member. The first sub-channel is communicated with the heat exchange pipes. The first member comprises protrusions facing the first sub-channel, and there are gaps in a left-right direction between the protrusions and the inner circumferential surface of a first circumferential wall defining the first sub-channel. The third sub-channel is communicated with the first sub-channel and the second sub-channel, and the fourth sub-channel is communicated with the first sub-channel and the second sub-channel. Therefore, when the heat exchanger in the present application works as an evaporator for a refrigerant, it is beneficial to dispersing the refrigerant, and the overall heat exchange performance is improved.
