The present invention relates to a heat exchanger. The purposes of the present invention are to easily manufacture and assemble heat exchange fins by allowing the heat exchange fins to be conveniently installed and fixed to be aligned in the longitudinal directions of heat exchange tubes at regular and relatively wide distances; and to improve the heat exchange performance of the heat exchanger by preventing the formation of water around the heat exchange fins, wherein the heat exchange fin has a fin main body formed into a thin metal sheet and having distance alignment protrusions formed into steps on the same, and the formation of the water is the problem of an existing heat exchange fin. According to the present invention for the purposes, the heat exchanger comprises: a pair headers facing each other up and down; the heat exchange tubes installed to be longitudinally arranged between the headers at regular distances; and the heat exchange fins formed into the thin metal sheets and installed to be aligned in the longitudinal directions of the heat exchange tubes at the regular distances, wherein the heat exchange fin has slots formed to penetrate the fin main body which has a certain thickness and area, and is formed into the thin metal sheet; arranged into multiple rows at regular distances back and forth, and left and right; corresponding to the cross sections of the heat exchange tubes; having extended ribs which are formed at the peripheries thereof, have certain thicknesses and heights, protrude to one side, and adhere to the outer surfaces of the heat exchange tubes; and having the distance alignment protrusions which are formed around the same and selectively protrude from the surface of the fin main body vertically upwards or vertically downwards. |
