PURPOSE: A fin for a heat exchanger is provided to increase the stay time of air between louvers of a fin by promoting air flowing along the surface into a warm current, and to improve the heat exchange efficiency of a heat exchanger by widening the contact area of air and a fin. CONSTITUTION: A fin for a heat exchanger is formed in a corrugated structure having a planar portion(4a) and a curved portion, wherein plural louvers(5) are formed along the air flow direction(X2) of the planar portion and an air passage(5e) is formed between adjacent louvers to penetrate an air flow path(AL), and plural louvers are divided into uneven louvers(51a,52a) and even louvers(51b,52b) and one of ends of the uneven louver and the even louver is formed to have the different vertical position. |
