HEAT TRANSFER PIPE WITH FIN MEMBER INTERNALLY MOUNTED

摘要

PROBLEM TO BE SOLVED: To provide a heat transfer pipe easy and inexpensive to manufacture by increasing a contact area between each of fin members arranged in the heat transfer pipe and an element pipe to improve the heat conductivity of the fin members to the element pipe and the heat exchanging performance of the heat transfer pipe and allow easy control of the heat exchanging performance of the heat transfer pipe. SOLUTION: The heat transfer pipe comprises a plurality of plate fins 3 provided protruding in mutual parallel perpendicularly to one face of a metal base plate 5. The cylindrical fin member 4 is formed with the base plate 5 in a cylindrically curved shape in the state of the plate fins 3 being located inside. The cylindrical fin members 4 are inserted in plural number in series to the metal element pipe 2 where the cylindrical outer peripheral faces of the base plates 5 of the fin members 4 are fixed in close contact with the inner peripheral face of the element pipe 2.
