PURPOSE:To prevent a heat pipe from being influenced by the direction of the flow of external fluid and to enable effective provision of heat conduction action even if the pipe is mounted in a region where the velocity of flow of the external fluid is low, by a method wherein, a fin part, where a number of fins formed by a curved wire material are protruded with a gap therebetween, is formed on the outer surface of the heat pipe. CONSTITUTION:Linear fins 5, each wound in a helical manner, are secured to the vaporizing part (a lower part in a drawing) and the condensing part (an upper part in a drawing) of a heat pipe 1. The fin 5 is formed by a metallic wire material having excellent thermal conductivity, wound in a circular manner with a proper gap in the direction of a helical axis therebetween, brought into axial contact with the outer periphery of the pipe 1, and the plural fins are disposed in a circumferential direction. The pipe 1 and the liner fins 5 are secured to each other, the fins are also secured to each other at a portion, where the linear fins 5 circumferentially adjoining each other are overlapped with other, to improve rigidity. The vaporizing part of the heat pipe is decreased in flow resistance and enables effective provision of heat conduction action since a proper gap is provided between the linear fins 5 even if the velocity of flow of external fluid to be cooled is low and the direction of its flow is inclined based on the axis of the pipe 1. |
