ABSTRACT:
There is provided heat exchange tube formed from a ductile metal strip which is formed into a generally circular configuration with the opposing longitudinal edges of the strip welded together. Both surfaces of the strip are enhanced. One surface of the tube is enhanced with protrusions in the shape of truncated cones. The ratio of the pitch between longitudinally aligned protrusions and transversely aligned protrusions maximizes the formation and maintenance of vortexes in a flowing fluid along the tube surface.
