配路と温水集合路とが形成される。(Prior Art) As a conventional heat exchanger, there is one described in Japanese Utility Model Application Publication No. 131268/1983. This heat exchanger is constructed by alternately stacking flat tubes and bellows-shaped corrugated fins, closing one end of each tube, and inserting the other end into a tank. This tank includes a tank body and an end plate that forms the bottom of the tank.
The inside of the tank is longitudinally divided into two by a partition, forming a hot water distribution path and a hot water collection path.

パス漏れを招くという問題がある。On the other hand, in the case of the heat exchanger described in Japanese Utility Model Application Publication No. 63-154962, tube insertion holes can be formed by punching, but unless the end plate has a high degree of flatness, the tube insertion hole must be of a certain depth. Since it is difficult to form grooves, brazing properties are poor and a gap is created between the partition and the end plate, which causes hot water to bypass from the hot water distribution path to the hot water collection path, which is the so-called bypass leak. There is the problem of inviting.
