Abstract
An improved heat transfer means provides for a dual corrugated fin material which improves heat transfer by increasing the surface area of the fin without a corresponding increase in volume. The improved heat transfer means comprises a fin generated from a flat sheet of metal. The fin includes a first corrugated pattern having a first height, and a second corrugated pattern having a second height, wherein the first pattern is integral in the second pattern and the first height is less than the second height.
