発明の名称 (英語) ROTATING MACHINE
発明の概要(英語) Provided is a rotating machine with which an increase in cooling efficiency can be achieved while preventing an increase in weight and cost of a rotor even when the diameter of the rotor is increased. The rotating machine is provided with a rotor rotating around a rotation axis line and a cooling machine. The rotor is provided with: a hollow refrigerant circulation portion formed at a radial direction central part along the rotation axis line; and a body to be cooled provided outside the refrigerant circulation portion in the radial direction. The rotating machine is provided with a fixed portion pipe for introducing a liquid-phase refrigerant cooled by the cooling machine into the refrigerant circulation portion, and for returning a gas-phase refrigerant in the refrigerant circulation portion from the refrigerant circulation portion to the cooling machine side. The rotor is equipped with: an introduction flow path for guiding the liquid-phase refrigerant to the vicinity of the body to be cooled via a first opening portion formed in a side wall along the rotation axis line of the refrigerant circulation portion; and a return flow path for returning, into the refrigerant circulation portion, the gas-phase refrigerant produced as a result of the liquid-phase refrigerant evaporating at the vicinity of the body to be cooled and thereby exchanging heat with the body to be cooled.
従来技術、競合技術の概要(英語) BACKGROUND ART
Conventional, for example superconducting rotating machine of the object such as a superconducting field pole is held in a superconducting state for the purpose of the rotating machine of the cooling device for cooling the object 1 as one of the, heat pipe or thermal siphon such as a system/method and the liquid-phase refrigerant is vaporized latent heat of the cooling structure to be cooled by means of a rotary machine has been known. For example, the structure shown in the following Patent Document 1, the cooling machine is cooled by the refrigerant liquefied by the condenser (liquid-phase refrigerant) is formed inside the rotor of the electric rotating machine through the connecting pipe is sent to the central cavity, the vaporized liquid-phase refrigerant of the central cavity of the central cavity is provided by winding around the winding holder with a holder is wound around the winding (the object) is configured so as to cool. In this configuration, in a liquid phase within a central cavity when the refrigerant is caused by a gas phase refrigerant, the connecting pipe is returned to the condenser through the same, and then cooling it again, is condensed by the liquid phase refrigerant.
