記載のヒートパイプ。[Claims for Utility Model Registration] 1. In a heat pipe in which one end of a sealed tube filled with a working fluid is used as a heat absorbing section and the other end is used as a heat radiating section, nucleate boiling is promoted on the inner surface of the heat absorbing section of the sealed tube. 1. A heat pipe characterized in that a spiral groove is disposed to cause the heat absorption to occur, an inner tube is inserted into the inner surface of the heat absorption part of the sealed tube, and the heat transfer coefficient is improved by the bubble coalescence effect of the narrow gap gap. 2. The heat pipe according to claim 1, wherein the spiral groove extends in a part of the longitudinal direction of the heat absorption portion. 3. The heat pipe according to claim 1, wherein the inner pipe extends in a part of the longitudinal direction of the heat absorption section.
