Abstract:
A fin-tube type of heat exchanger has: a plurality of fins laminated to one another; a housing for containing therein the fins; and a heat transfer tube penetrating the fins in a fin-laminating direction and also penetrating side plates on both sides of the housing. A heat transfer tube through hole is formed in one-side side plate of the housing by a burred hole having a tubular flange part protruded into the housing. Each fin has a brazing material insertion hole adjacent to the heat transfer tube through hole. That portion of a brazing material which protrudes from the brazing material insertion hole of the outermost fin closest to the one-side side plate part toward the one-side side plate part gets molten. The tubular flange part has a cutout part formed, at a circumferential position facing the brazing material insertion hole, by partly cutting away the tubular flange part.

Claim (Index 3):
The fin-tube type of heat exchanger according to  claim 1 , wherein, provided that a product of an area of the cutout part and a thickness of the tubular flange part is defined to be a volume of the cutout part, the volume of the cutout part is smaller than the volume of that portion of the brazing material which protrudes from the brazing material insertion hole in the outermost fin toward the side plate part on the one side.
