いう問題がある。However, the above (1)
In the above, since the connecting part on the end plate side is arranged inside the connecting part on the tank side and connected, it contributes to the reinforcement of the end plate, but prior to brazing, both connecting parts are connected by multiple point welding. Since it is temporarily attached, the tolerance of the axial movement is lost, the axial deformation of the tank or the end plate accompanying the thermal expansion at the time of brazing is suppressed, both are twisted and deformed, and between the two joints There is a possibility that a gap is generated and the connection is not reliably performed. In addition, since spot welding is required in advance, there is a problem that the appearance is poor, and it is troublesome and mass production is difficult.

問題もある。In the above (2), since both connecting portions extend laterally, reinforcement of the end plate is insufficient, and further, the connecting portion on the tank side is sandwiched between the claws. Due to the structure, the tolerance of the tank and the end plate in the axial direction is lost similarly to the above (1), and the tank and the end plate may be twisted and deformed by thermal expansion. There is also a problem that it is difficult to bend the nail portion into a proper U-shape.

1 is provided with a tube insertion hole 13. Both the tank 7 and the end plate 11 are formed in curved surfaces bulging outward, and have a substantially elliptical cross section. In this specific example, in order to increase the pressure resistance, the radius of curvature of the tank curved surface is formed larger than the end plate. At both ends of the tank 7 and the end plate 11, flat connecting portions 8 and 12 are formed along the axial direction. The connecting portion 8 of the tank 7 is bent to the side of the end plate 11 after being directed to the side, and a step portion 9 is formed inside, and the distal end surface of the connecting portion 12 of the end plate 11 contacts the step portion 9. It is joined in a state in which it is positioned, thereby enabling positioning and improving the assemblability. In the drawing, reference numeral 14 denotes a blind cap for closing the upper and lower openings of the header pipe 4.

In this specific example, they are provided at six locations, for example, at 60 cm intervals. In addition, the number may be 10 at 30 cm intervals, 4 at 90 cm intervals, or may be provided as appropriate. Then, after coupling the tank 7 and the end plate 11,
These holding pieces 10 are brought into contact with each other along the curved outer peripheral surface of the end plate 11 by caulking from a state shown by a two-dot chain line in FIG. 2 to a state shown by a solid line. Therefore, the end plate 11 is assembled with the holding pieces 10 pressed against the tank 7. As a result, at the time of brazing, both the tank 7 and the end plate 11 are allowed to move in the axial direction due to the thermal expansion, no torsional deformation occurs, and the tip end surface of the end plate side coupling portion 12 and the tank It is possible to reliably perform integral brazing without forming a gap between the side connecting portion 8 and the step portion 9. In addition, spot welding is not required prior to brazing, and the appearance is not impaired. In addition, since each holding piece is integrally joined to the end plate by brazing, the pressure resistance of the pipe is further improved.
