As shown by the dotted line, the manifold 4 is displaced in the rotational direction around the communication port 9. For this reason, when brazing is performed with such positional deviation occurring during temporary assembly of the heat exchanger, the gap between the manifold 4 and the communication port 9 of the tank portion 3 will not be sufficiently filled with braze, There was a problem that brazing failure occurred. A jig may be used to fix the manifold 4, but this causes a problem that temporary assembly takes time. The present invention has been made in view of the above problems, and an object of the present invention is to provide a heat exchanger in which the manifold is not displaced and can be easily assembled without using a jig.

ク部１５の外周面に接する。Assembly of the heat exchanger having the above-described structure will be described. First, after the heat exchanger plates 11 are alternately laminated with corrugated fins (not shown), the manifold 12 is inserted into the outermost heat exchanger plate 11, and the burring 21 of the fixed portion 19 of the manifold 12 is attached to one tank. Part 1

に行えるうえ、確実にろう付けされる。Here, the center of the communication port 16 of the tank portion 14 is set as the rotation center O of the manifold 12, the distance from the rotation center O to the end of the burring 21 is L 1 , and the rotation center O to the engagement edge 22. The distance is L 2 , the distance from the rotation center O to the end of the connecting portion 18 is L 3 , the burring 21 and the communication port 1
When a line diagram is drawn as shown in FIG. 3 with a gap of 6 as C, conventionally, as shown by a chain double-dashed line in FIG.
Since the portion of the burring 21 separated by 1 contacts the communication port 16, the connecting portion 18 of the manifold 12 separated by L 3 from the rotation center O was displaced by A. On the other hand, in the present invention, even if the gap C between the burring 21 and the communication port 16 is the same, the positioning position L 2 by the engaging edge 22 is farther than the conventional L 1 , so that the connecting portion 18 The positional shift amount B is smaller than the conventional positional shift amount A. In this way, since the manifold 12 is positioned and the positional deviation is reduced, temporary assembly can be easily performed and reliable brazing can be performed without using a jig.

The manifold 12 has a fixing portion 19 and a connecting portion 18 which are basically the same as those of the first aspect of the invention, but the engaging edge 22 as in the first aspect of the invention is not formed. Instead, an engagement tube portion 24 having a rectangular tubular cross section that is thicker than the fixed portion 19 but thinner than the connected portion 18 is formed between the fixed portion 19 and the connecting portion 18. The engagement tube portion 24 is the heat exchange plate 1
