PROBLEM TO BE SOLVED: To provide a heat pipe with fin capable of efficiently and stably dissipating the heat of an electronic equipment device or electronic part while saving the space. SOLUTION: This heat pipe with fin comprises rotational pipes with fin 3a and 3b rotatably provided on the circumferential surface of a heat pipe 1 while having heat conductivity with the heat pipe 1. The rotational pipes 3a and 3b are rotated, whereby fins 4a and 4b are rotated to circulate high-temperature air. Accordingly, setting of a fan is dispensed with, and the space can be saved. Since the rotational pipes 3a and 3b have heat conductivity with the heat pipe 1, heat absorption or heat radiation by the heat pipe 1 can be efficiently performed. Since the heat pipe 1 is not rotated, the heat pipe 1 is never deformed, and a satisfactory radiation effect can be stably obtained. COPYRIGHT: (C)2006,JPO&NCIPI
