A heat exchange fin of a heat exchanger is provided to form paths for condensed water by a single slit formed inside to simplify discharge of the condensed water with reduced air resistance, thereby increasing a discharging amount of air with respect to power consumption. A heat exchange fin of a heat exchanger includes a plurality of coupling holes(100) contacting heating pipes to transfer heat and a plurality of slits formed on a base surface(102). The slits are formed of first to fourth slits(120,130,150,165). The first slit has first central leg parts(110), a first heat exchange panel part(112), and first both side leg parts(115). The first central leg parts are separated from each other in the center of an air path formed between the coupling holes and forming a path of which a lower part become narrower in the air flow direction. The first heat exchange panel parts are extended from the first central leg parts laterally and inclined toward the lower parts in the air flow direction. The first both side leg parts are supported on the base surface. The second slit has a second heat exchange panel part(122) formed vertically at lower parts of the first slits, and second leg parts(125) formed in the same manner with the first side leg parts. The third slit has a third heat exchange panel part(142) with a distance from the second slit for providing a path for moisture, and third leg parts(145) formed in the same manner with the first side leg parts but intervals therebetween, which become wider toward the lower part in the air flow direction. The fourth slit has fourth central leg parts(152), fourth heat exchange panel parts(157), and fourth side leg parts(160) respectively formed symmetrically with those of the first slits. |
