Abstract

PURPOSE: To manufacture a corrugated fin having an oblique corrugation, which is suited for use in a heat exchanger for a car heater, car cooler, etc., by applying a primary corrugation forming treatment and a louver forming treatment to a material strip, and then applying a secondary corrugation forming treatment to the strip.
CONSTITUTION: A strip material 1 is at first carried to a primary shaping machine 2 for shaping the strip 1 into a corrugated strip 1A formed with corrugation having an apex angle of 90°. Then, the strip 1A is carried one pitch after another to a louver forming machine 4 by a primary feeding means 3. At the machine 4, a corrugated strip 1B is obtained by forming louvers in the corrugated surfaces of the strip 1A. Then, the strip 1B is carried one pitch after another to a secondary shaping machine 6 by a secondary feeding means 5. At the machine 6, the strip 1B is shaped into a corrugated strip 1C having oblique corrugation, the apex angle of which is corrected into a required angle. Thereafter, a corrugated fin 8 is obtained by counting the number of corrugation formed on the strip 1C and cutting the strip 1C when a predetermined number of corrugation is counted.
