Claims

[Scope of utility model registration request]

A large number of pairs of cuts are provided on the windward edge, and the middle part of each pair of cuts is bent along a line connecting the tips of both cuts, and both sides of the two cuts are bent. A plate fin for a heat exchanger, which is formed by bending the intermediate portion in a direction opposite to the above-mentioned intermediate portion along a line that connects the tip of the cut and the windward edge and is inclined with respect to the air flow direction.
