Claims

[Claims for Utility Model Registration] In a heat exchanger in which a plurality of flat tubes and fins are stacked in an alternating arrangement, and both ends of each tube are inserted into a pair of headers and connected in communication, A protruding strip is integrally formed along the longitudinal direction on the outer circumferential surface, and the protruding strip is cut diagonally at the tube end to have an inclined end, while the tube end is connected to the header. The tube is inserted into a tube insertion hole drilled in the tube, and the inclined end portion is fitted into a notch formed at a corresponding position on the periphery of the insertion hole, and the inclined end surface is inserted into the notch portion. A heat exchanger characterized by being in contact with a corresponding inner peripheral surface.
