Heat exchanger and manufacturing method thereof |
| abstract |
A heat exchanger that can be manufactured easily and at low cost while appropriately reducing the number of components and simplifying the configuration. In the heat exchanger HE, the end portion of each heat transfer tube 1 is joined to the tip wall portion 22b of the bulging portion 22 formed on the side wall portion 21 of the case 2, and the opening edge portion 33 of the header 3 is expanded. A chamber 36 communicating with the inside of each heat transfer tube 1 is formed by being externally fitted to the outlet 22, and the inner periphery of the opening edge 33 of the header 3 is used as a means for joining the header 3 to the side wall 21. The front end of the surface is formed in the first curved surface portion 33a having a convex cross section, and the second curved surface portion 23a having a concave cross section is formed on the outer surface of the peripheral wall portion 22b of the bulging portion 22, and the first and first Means for welding the two curved surface portions 33a and 23a to each other and its peripheral region in a state where the two curved surface portions 33a and 23a are in surface contact with each other is employed.
