ン。 In a louvered fin in which a large number of louvers are formed on a thin metal plate, the front edge of the louver is formed into a wave shape by connecting a plurality of protrusions that become narrower toward the end, and each protrusion is formed into a louver. The height of each protrusion is 0.5 to 2 times the pitch of adjacent protrusions, and 0.5 to 2 times the width of each louver.
A louvered fin characterized by 3 to 0.8 times the size.
