Header 1 includes a first tube member 13 and a second tube member 18. The first pipe member 13 has a first mounting portion 14, and the first mounting portion 14 is formed with a plurality of first mounting holes. The second pipe member 18 is connected to the first pipe member 13, the second pipe member 18 and the first pipe member 13 are formed separately, the second pipe member 18 has a second mounting portion 19, and the second mounting portion 19 is formed with a plurality of second mounting holes. By forming the first pipe member 13 and the second pipe member 18 separately, the first mounting portion 14 can be perforated with a cutter to form a first mounting hole, and the second mounting portion 19 can be perforated with a cutter to form a second mounting hole, so that the first pipe member 13 and the second pipe member 18 can be perforated separately to form mounting holes.
Wherein, the second mounting portion 19 overlaps with the first mounting portion 14 and forms a mounting plate 22 for mounting the heat exchange unit 3 of the heat exchanger 100, and the plurality of second mounting holes and the plurality of first mounting holes are respectively in one-to-one correspondence, and each second mounting hole and the corresponding first mounting hole jointly form a plugging hole 21 for plugging the heat exchange unit 3.

When the ratio of the thickness of the first mounting portion 14 to the thickness of the second mounting portion 19 is smaller or larger than the range, the difference between the thickness of the first mounting portion 14 and the thickness of the second mounting portion 19 is too large, and when the cutter is used for punching holes, the first mounting portion 14 or the second mounting portion 19 with too large thickness can cause the cutter to be broken easily, so that the process stability is lower when the first mounting portion 14 is provided with the first mounting hole or the second mounting portion 19 is provided with the second mounting hole.
The range of the ratio of the thickness of the first mounting portion 14 to the thickness of the second mounting portion 19 is limited to be within the range, and the thickness of the first mounting portion 14 and the thickness of the second mounting portion 19 are not greatly different, so that when the cutters are used for perforating the first mounting portion 14 and the second mounting portion 19, the cutters are not easily broken, and the process stability of the processing of the first mounting hole and the second mounting hole can be improved.
