Claims

[Scope of utility model registration request]

In a corrugated fin with louvers for a heat exchanger, a corrugated fin with louvers for a heat exchanger is formed by forming a band-shaped metal plate in a zigzag pattern, and having curved parts and flat parts consecutively arranged alternately, and each flat part is provided with a plurality of louvers. A corrugated fin with a louver for a heat exchanger, characterized in that a tongue piece is formed protruding from the front edge on the windward side of the end part, and the tongue piece is bent so as to be inclined with respect to the air flow direction.
