<p>A method of forming serrated-fin tubing to improve heat transfer performance is disclosed. The method comprises providing a round metal tube having an annular peripheral wall and integral inner metal fins projecting from such wall parallel to each other, and inserting a tool into said tube for interrupting the continuity of such fins so as to promote turbulence in the boundary layer of the flow in the tube thus improving heat transfer performance.</p> |
