発明の名称 (英語) ROTATING MACHINE
発明の概要(英語) A rotating machine allows a body to be cooled in a rotor rotating around a rotation axis line to be cooled by the thermosiphon effect and is provided with: a condensing unit disposed outside the rotor and condensing a refrigerant; an evaporation unit for evaporating, inside the rotor, the liquid-phase refrigerant condensed by the condensing unit to exchange heat with the body to be cooled; and a connecting pipe allowing the refrigerant to flow back and forth between the evaporation unit and the condensing unit and having a bend portion. The connecting pipe has a pipe structure in which a liquid-phase refrigerant flow path in which the liquid-phase refrigerant condensed in the condensing unit circulates and a gas-phase refrigerant flow path in which the gas-phase refrigerant evaporated in the evaporation unit circulates are each provided separately. This makes it possible for the rotating machine to stably maintain a heat transport capability between the condensing unit and the evaporation unit even when the entire device tilts or swings.
従来技術、競合技術の概要(英語) BACKGROUND ART
In recent years, high-temperature superconducting (HTS) winding HTS wire and the magnet and the spread range of applications, for example, the HTS superconducting rotating machine that uses a magnet rotary machine and the like have been developed.
Incidentally, before and after the HTS material has a critical temperature of 90K for, using a cooling machine such as the number K of several tens of K HTS wire to the extent that it is necessary to cool the windings. In particular, in the superconducting rotating machine of the marine vessel, for generating a large thermal load, it is possible to secure a sufficient cooling ability, for example, GM type refrigerator and the like of the cooling machine is utilized. In addition, HTS material is used for a ship in the superconducting rotating machine, the field pole HTS mounted on the rotation of the field magneton in a case of adopting a magnetic field type, the cooling machine is directly connected to the HTS magnet directly cooled by the heat transfer cooling scheme is not available. Therefore, the cooling device between the rotor and, using a coolant is thermally connected to the used method. Such methods include, for example, GM type refrigerator such as the refrigerant cooled by the cooler (for example, neon, nitrogen or the like) is used, a field pole by natural convection cooling of the HTS the thermal siphon cooling system and the like. For example, a thermal siphon cooling system is used as the superconducting rotating machine, the superconducting device shown in Patent Document 1 has been proposed.
