Therefore, it is necessary to accurately align the support insertion hole 5 with the end portion 14. To do so, there is almost no gap between them, and the end 14 is
However, the operation is extremely troublesome, and at this time, the end portion 14 may collide with the edge of the support insertion hole 5 and may be deformed. For this reason, the insertion work of the end portion 14 must be performed very carefully, and there is a disadvantage that mass production is lacking. Therefore, the present invention provides a core support 6
It is an object of the present invention to provide a device that can easily insert the end portion 14 into the support insertion hole 5 and that can securely and liquid-tightly fix both insertion portions at the time of brazing.

ータの製造方法。1. A plurality of flat tube insertion holes 2 of the same shape are formed in a tube plate 1 at regular intervals in a longitudinal direction thereof, and the tube plate 1 is provided at the edge of the tube insertion hole 2. Burring processing 3 protruding inward
In a method of manufacturing a radiator in which the end portion of the flat tube 4 is inserted into each tube insertion hole 2 and the insertion portion of the flat tube 4 is liquid-tight brazed in a furnace, At both ends in the longitudinal direction, flat support insertion holes 5 having burring processing 3 whose hole edges protrude toward the inner surface side of the tube plate 1 are formed, and ends of the core support 6 aligned with the support insertion holes 5. Department
In the state where the end 14 is inserted from the outer surface of the tube plate 1 into the support insertion hole 5, the burring portion of the hole edge of the support insertion hole 5 is swaged from the inner surface to the outer surface. As a result, the opening of the support insertion hole 5 is reduced to fix the space between the core support 6 and the tube plate 1, and then the space between the insertion portion of the tube plate 1 and the core support 6 is integrated and liquid-tight in the furnace. Manufacturing method of radiator fixed by brazing.
