PURPOSE:To make it hard to generate dry-out by a method wherein a heat pipe is constituted of the double structure of a tubular inner tube and an outer tube and an annular operating liquid passage is formed between the inner tube, bored with a multitude of fine holes, and the outer tube while a vapor passage is formed in the inner tube respectively. CONSTITUTION:The amount of heat from a heat generating equipment is conducted through an outer tube 14 and is transferred to operating liquid, existing in an annular operating liquid flow passage 15 between an inner tube 12 and the outer tube 14, while the heat is changed into the latent heat of vapor, evaporated through the groups of fine holes 12a of the inner tube 12, and the vapor flows to a low-temperature section through a vapor flow passage 16, then, the heat is changed into condensing heat and is discharged to the outside of a pipe. According to this constitution, the circumferential movement as well as the axial movement of the flow of the operating liquid may be permitted by a pressure difference in a capillary tube, which is generated from the annular operating liquid flow passage 15 between the inner tube 12 and the outer tube 14, even when the evaporating section 15b of the heat pipe and the condensing section 15a of the same are positioned at opposite side whereby the liquid in the condensing section 15a may readily be returned to the evaporating section 15b and dry-out may hardly be generated. |
