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.
