1. A heat exchanger, comprising:
a first pipe and a second pipe, the first pipe comprising a circumferential wall and a main channel surrounded by the circumferential wall;
an inlet/outlet pipe connected to the first pipe;
a plurality of heat exchange tubes, wherein each of the plurality of heat exchange tubes is connected to the first pipe and the second pipe, each of the plurality of heat exchange tubes comprises a plurality of channels arranged to be spaced apart, each of the plurality of channels is connected to the first pipe and the second pipe, and the plurality of channels comprise a first channel and a second channel, wherein, on a cross section of the plurality of heat exchange tubes taken along a left-right direction, a flow cross-sectional area of the first channel is greater than a flow cross-sectional area of another channel different from the first channel in the plurality of channels, and a flow cross-sectional area of the second channel is less than a flow cross-sectional area of another channel different from the second channel in the plurality of channels; and
a first member, wherein the first member is disposed in the main channel of the first pipe, the first member extends by a predetermined distance along a length direction of the first pipe, the main channel comprises a first flow channel and a second flow channel, the first member is disposed between the first flow channel and the second flow channel, the first flow channel is connected to the inlet/outlet pipe, the second flow channel is connected to each of the plurality of heat exchange tubes, the first member comprises a plurality of through-holes, and each of the plurality of through-holes connects the first flow channel and the second flow channel,
wherein A1 denotes the flow cross-sectional area of the first channel on the cross section of the plurality of heat exchange tubes taken along the left-right direction, A2 denotes the flow cross-sectional area of the second channel on the cross section of the plurality of heat exchange tubes taken along the left-right direction, and the A1 and A2 satisfy a following expression: 0.15≤(A1−A2)*N/A3<3.8, wherein A3 denotes a sum of flow cross-sectional areas of the plurality of through-holes of the first member taken along the left-right direction, and N denotes a quantity of all of the plurality of heat exchange tubes connected to the main channel.
