を連通している。(E) Example of the invention Hereinafter, an example of the invention will be described based on the drawings. FIGS. 1 to 3 are diagrams showing an embodiment in which this invention is applied to a radiator for an automobile.
In FIG. 1, 21 is the seat plate of the upper tank 22;
3 is the seat plate of the lower tank 24, and these two seat plates 2
A plurality of flat tubes 25 each having a substantially elliptical cross section and provided with fins (not shown) are bridged between the tubes 1 and 22 . As shown in detail in FIGS. 2 and 3, the seat plate 21 has a plurality of approximately elliptical holes 21a.
The seat plate 23 is also formed with a plurality of holes 23a having a substantially circular cross section. The seat plate 23 is
A substantially cylindrical mounting portion 26 that projects upward is formed at the periphery of each hole 23a by burring. The upper end of each tube 25 penetrates the hole 21a of the seat plate 21 and protrudes into the upper tank 22,
Further, its lower end portion is formed to have a substantially circular cross section and fits into a mounting portion 26 at the edge of the hole 23a of the seat plate 23, thereby communicating the upper tank 22 and the lower tank 24 so that the cooling water can flow. .

工程が繁雑となることも無く、従来のものと同様
に製造され得る。 Such a radiator is manufactured as follows. First, after placing foil solder on the seat plate 23,
The lower end of the tube 25 is fitted into the attachment part 26 of the seat plate 23 with this solder in between, and the fitting part between the seat plate 23 and the tube 25 is heated and brazed.
Then, the seat plate 21 is attached so that the upper end of the tube 25 brazed to the seat plate 23 fits into the hole 21a of the seat plate 21. Therefore, the manufacturing process is not complicated and can be manufactured in the same manner as conventional ones.
