Title: ROTATING MACHINE
Abstract:
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.
