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 1):
A fin-tube type of heat exchanger comprising:\n a plurality of fins laminated to one another; a housing for containing therein the fins; a heat transfer tube which penetrates the fins in a fin-laminating direction and which also penetrates side plate parts on both sides, in the fin-laminating direction, of the housing, wherein a heat transfer tube through hole which is formed in an at least one-side side plate part, in the fin-laminating direction, of the housing is constituted by a burred hole having a tubular flange part protruded into the housing, wherein each of the fins has a brazing material insertion hole formed adjacent to the heat transfer tube through hole formed in each of the fins; wherein that portion of a brazing material which protrudes from the brazing material insertion hole in an outermost fin closest to the one-side side plate part toward the one-side side plate part is caused to get molten so that the heat transfer tube is brazed to the tubular flange part; and wherein the tubular flange part has formed, at a position of a circumferential portion facing the direction in which the brazing material insertion hole is present, a cutout part in which a part of the tubular flange part has been cut out.
