Abstract
An air cooled, finned heat exchanger tube includes a metallic tube through which fluid to be cooled is flowable. The tube has an outer surface on which axially spaced axial indentations are formed over its circumference, and a plurality of axially spaced fins each of which has a main element formed with heat transfer promoting patterns and a base angled with respect to said main element. The base is frictionally and irremovably secured within a corresponding indentation so that said tube outer surface is completely covered.
