を特徴とする熱交換器。 The burring part of the fin into which the tube is inserted has a short tube shape with a flange-like curved end surface, and the fins have a stacked structure in which the curved end surface of the burring part is used as a stopper when stacking the fins in close contact with the adjacent fins. In the heat exchanger, at least one groove portion is provided that communicates with the outside a closed annular space formed between the tube and the laminated fins by the curvature of the rising portion and the curving portion of the burring portion. , A heat exchanger characterized in that a bent end face of the burring portion and a fin form a close contact portion.
