The present invention relates to a finned pipe shaped heat exchanger and an extrusion method of a spiral induction piece thereof. More specifically, a spiral induction piece is inserted into the finned pipe shaped heat exchanger to increase a heat exchange area and time of heat exchanging to maximize heat exchanging efficiency. A spiral heat-dissipation fin (11) is integrally formed in the outside of a fin pipe (10) and the heat exchanger (1) includes the fin pipe wherein a spiral induction piece is inserted. The spiral induction piece (20) twists a plate where wings (22) are formed on both sides of a circular center part (21) in the center to have a spiral shape. |
