Abstract
A roll forming tool for manufacturing louvered serpentine fins. The tool has a plurality of fin blades each having a predetermined size and shape. Each of the blades has a plurality of cutting edges for forming scallops in a serpentine fin such that a louvered serpentine fin is formed. The blade forms the louvers in the fins that create a turbulent air flow and thus increase the rate of heat exchange in a heat exchanger.
