PURPOSE: A finned tube for a heat exchanger is provided to accomplish active heat transfer since the fluid flowing between filns is well mixed and stays long. CONSTITUTION: A fin tube for a heat exchanger tube(100) comprises a heat pipe(110) and fisns(120). Each fin comprises a first hole(130), a second holes(200), and guide pieces(300). The heat pipe is inserted into the first hole. The fluid flows through the second holes. Guide pieces induce the fluid flow to the second holes. Each fin is formed by repetitively folding the metal plate in a band form at regular intervals. The guide piece is tilted from the upper end or the lower end of the second hole at a certain angle. |
