ABSTRACT:
A nucleate boiling surface is formed on at least one side of a strip by roll forming. A first pattern of grooves separated by ridges in the form of a double helix is rolled into a strip. A second pattern of more shallow grooves is then machined into the ridges. The ridges are then deformed so that the fin ends extend over the first pattern of grooves forming subsurface channels. Concomitantly, the second pattern of grooves forms a plurality of pores intersecting the subsurface channels.
