HEAT TRANSFER PIPE HAVING FIN MEMBER OUTSIDE, PARTICULARLY REGARDING TO IMPROVE THE PERFORMANCE OF HEAT EXCHANGE BY IMPROVING THERMAL CONDUCTION BETWEEN METAL PIPE AND FIN MEMBER

摘要

PURPOSE: A heat transfer pipe having a fin member outside is provided to improve the performance of heat exchange by improving thermal conduction between a metal pipe and a fin member by preventing generation of a gap between the metal pipe and the fin member. CONSTITUTION: A resin film layer(2) is installed on an outer peripheral surface of a metal pipe(1). A metal fin member(3) is wound on an outer peripheral surface of the resin film layer in a helical shape with contacting one section thereof with the resin film layer. The wound contact part penetrates a surface of the resin film layer. The thickness of the resin film layer is in a range of 0.1 to 1.0mm.
