<p>A heat exchanger includes an auxiliary heat exchanger 8, which has plate-shaped first fins 10 and a plurality of first heat transfer tubes, and a main heat exchanger 9 which has plate-shaped second fins 20 and a plurality of second heat transfer tubes. A plurality of burrs 14, 15 are present at specified intervals on edges 16, 17 of the first fins 10. The auxiliary heat exchanger 8 and the main heat exchanger 9 are so positioned that the edges 16, 17 of the first fins 10 on which the burrs 14, 15 are present are in contact with edges 26, 27 of the second fins 20, and the edges 16, 17 having the burrs 14, 15 present thereon are positioned on the inner side.</p> |
