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.
Claims16
A tool for manufacturing scalloped, louvered serpentine fins comprising:
- two rotatable wheel assemblies;
- a plurality of fin blades included in each of said wheel assemblies;
- each of said fin blades including one or more teeth, each tooth having a peak and a valley;
- one or more cutting surfaces, each cutting surface lying between a peak and a valley;
- and
- a plurality of serrations formed on at least one of said one or more cutting surfaces for creating the scalloped, louvered serpentine fin from a workpiece that is passed between said two wheel assemblies.
