Abstract
A heat exchanger includes a first pipe, a second pipe, a plurality of heat exchange tubes, an inlet/outlet pipe, and a first member. The first pipe has a main channel, and the heat exchange tube is connected between the first pipe and the second pipe. The heat exchange tube includes a plurality of channels disposed to be spaced apart. The plurality of channels include a first channel with a largest flow cross-sectional area and a second channel with a smallest flow cross-sectional area. The first member is located in the main channel of the first pipe to define a first flow channel and a second flow channel. The first flow channel is connected to the inlet/outlet pipe, and the second flow channel is connected to the heat exchange tube. The first member includes through-holes.
