った。However, in the conventional heat exchanger, since the tube 2 is inserted into the header-pipe 1, the inner diameter of the header-pipe 1 is at least larger than the width of the tube 2. Must also be large. Therefore, there is a problem that the internal volume of the header-pipe 1 that is not directly involved in heat exchange becomes large, and the amount of heat medium used increases. Freon gas, which has been regarded as a problem in recent years, is often used as the heat medium, and an increase in the amount of heat medium used may not only increase the cost but also lead to environmental damage.

ている。In FIG. 1, reference numeral 4 denotes a header pipe, and a curved portion 4a that curves toward the inside of the header pipe 4 is formed on a part of the circumferential direction, that is, on the side surface on the tube insertion side. The curved portion 4a is formed in advance when the header-pipe 4 is manufactured by the extrusion manufacturing method, or as shown in FIG. 2 (a), a circular header-pipe 4'having a circular tubular shape similar to the conventional example. Is prepared, and a round bar-shaped jig A is pressed against its side surface as shown in FIG. 2 (b). Reference numeral 4b is a lid that closes the upper and lower ends of the header-pipe 4, and has the same shape as the cross-sectional shape of the header-pipe 4.

Since it is smaller than the circular one by about two-thirds, the amount of heat medium used is reduced, which can contribute to cost reduction and CFC regulation. Further, as shown in FIG. 3, since the curved portion 4a is formed on the side surface of the header pipe 4 on the tube insertion side, the tube 2 is deeper than before, that is, the insertion end of the tube 2 is the header. It can be inserted until it hits the inner surface of the pipe 4. Therefore, the inserted tube 2 can be positioned by the contact between the tube 2 and the header pipe 4.
