Abstract:
1. A corrugated fin comprising: a first corrugated fin portion having a first fin width corresponding to a first type of heat exchanger; a second corrugated fin portion having a second fin width corresponding to a second type of heat exchanger, with said first and second corrugated fin portions being integrally adjacent one another, and with said first fin width being less than said second fin width; a first louver on said first corrugated fin portion so as to extend corresponding to said first fin width, said first louver having first louver slats inclined in a first direction at a first predetermined angle; and a second louver on said second corrugated fin portion so as to extend corresponding to said second fin width, said second louver having second louver slats inclined in a second direction at a second predetermined angle, with said first direction being different from said second direction, wherein a processed amount per unit width of said second louver is less than a processed amount per unit width of said first louver so as to balance residual stress between said first and second corrugated fin portions and thereby prevent bending of the corrugated fin in its entirety.
