Abstract
The current invention includes a tube with a helical fin extending from the tube's outer surface. The fins and tube are monolithic, or formed of one part. The fin is continuous and the fin base is essentially straight as it winds around the tube. The fin has a tip opposite the fin base with an essentially straight fin body as viewed between the tip and the base. The fin is bent into concave and convex shapes about the tube wall so the fin tip makes a wavy pattern as it winds around the tube.
