ABSTRACT:
It is an object of this invention to obtain a heat conduction pipe superior in corrosion resistance as well as heat exchange efficiency between fluid flowing respectively through an inside and an outside for great heat radiation property and endothermic characteristics. It is also object of this invention to form the heat conduction pipe superior in the corrosion resistance as well as the heat radiation property and endothermic characteristics at inexpensive price. To achieve the above, at least single resin coating layer is formed on an outer circumferential surface of a metal pipe, a metal fin member is spirally wound on an outer circumferential surface of the resin coating layer with a side end surface the metal fin member in contact. The winding contact portion is made to encroach a surface of the resin coating layer to form the heat conduction pipe.
