Enhancement of thermal transmission of pipes by increasing surface area uses springs attached to outer surfaces to act as fins

摘要

The procedure uses springs of round or other section, joined together and fitted over a tube to act as thermal transmission fins. The springs can be attached to the pipes by welding or other means, and can be fitted to pipes that have been shaped, e.g. by bending, modification of fdiameter or flattening, at any stage of the manufacturing process.
