Due to the curved bent portion 24 formed to facilitate mold cutting, a gap 25 having a substantially triangular cross section is inevitably formed between the bent portion 24 and the pipes 18, 19 in the axial direction of the pipes 18, 19. A pair will occur. Since the gap 25 is provided, even if the pipes 18 and 19 are fitted into the collecting pipes 15 and 16 and brazed in a furnace, the brazing material will not enter the gap 25, and the gap will generally be closed. Therefore, as mentioned above, it is necessary to perform arc welding from the outside so as to close the gap 25 and the outer peripheral surfaces of the pipes 15 and 16, which is a problem in terms of cost and workability. It was hot.

際に、前記パイプ１８，１９の位置がずれたり、
あるいは、はずれたりすることがない。 As shown in FIG. 2, two long groove-shaped fitting recesses 31 are formed in the inner wall surface of the pipe fitting portion 21 to face each other and intersect with the joint portions 22a and 22b. Further, on the outer surfaces of the ends of the pipes 18 and 19, two fitting protrusions 32 that fit into the fitting recesses 31 are formed to face each other. Therefore, the fitting concave portion 31 and the fitting convex portion 32 form a gap closing portion 33, and this gap closing portion 3
3 is provided so as to intersect with the gap 25 formed between the pipes 18, 19 and the joints 22a, b, so the gap closing part 33 serves as a dam for the gap 25, so to speak. That is, as shown in FIG. 4, the bonding surface 34 between the fitting concave portion 31 and the fitting convex portion 32, which bulges outward from the gap 25, is very tight, making it easy to perform furnace brazing. Moreover, it is reliably brazed, and even if the refrigerant were to flow from the direction of arrow B, it would be blocked by this adhesive surface 34. Here, since the fitting recess 31 is provided with a portion 35 that does not protrude on the outer periphery of the pipe fitting insertion part 21, the fitting protrusion 3 of the pipes 18, 19
2, the pipes 18 and 19 can be reliably positioned in the radial and thrust directions. Therefore, during furnace brazing, the positions of the pipes 18 and 19 may shift,
Or it never comes off.

After aligning a and b, the pipes 18 and 19 are inserted into the pipe fitting portion 21 so that the gap portion 25 and bead portion 36 are fitted. Therefore, since the gap 25 is closed by the bead 36, furnace brazing can be performed, and the positions of the pipes 18 and 19 can be fixed by using the gap 25 and the bead 36. Since this is done by mating,
For furnace brazing. The positions of the pipes 18 and 19 will not shift.
