Undulating louver fin for plate heat exchanger comprises set of undulating legs connected alternately by undulating top and undulating base and provided with inclined flaps cut in legs
The fin comprises a set of undulating legs (23) connected alternately by an undulating top and by an undulating base. The legs are provided with flaps (25) cut in the legs and inclined at an angle ( alpha ) relative to the principal undulating direction (D1). The legs have a thickness (e), an average transverse spacing (w) which define the width of the passage channel and the flaps have a length (ls) greater than the pitch (p). An Independent claim is included for a heat exchanger utilizing the fins.
