ABSTRACT:
Heat transfer tubes are provided internally with extended surfaces to improve heat transfer between a fluid within the tube and a fluid outside of and in contact with the tube. A flat sheet of metal is provided with extended surfaces which are welded to one side of the sheet, so that a tube with internal extended surfaces can be formed by bending the sheet so that it envelopes the surfaces and welding sides of the sheets together.
