Abstract:
Provided is a rotary machine capable of increasing cooling efficiency while preventing an increase in the weight and cost of a rotor even in a case where the diameter of the rotor is increased. A rotary machine including a rotor which is rotatable around a rotational axis, and a cooling device, wherein the rotor includes: a hollow cooling medium flow section provided in a center portion of the rotor in a radial direction and extending along the rotational axis; and a cooling target provided outward of the cooling medium flow section in the radial direction, and the rotary machine comprises a stationary section pipe which introduces a liquid phase cooling medium generated by cooling in the cooling device into the cooling medium flow section, and returns a gas phase cooling medium present in an inside of the cooling medium flow section from the cooling medium flow section toward the cooling device, the rotor including: a leading passage which leads the liquid phase cooling medium to a region which is in the vicinity of the cooling target through a first opening formed in a side surface of the cooling medium flow section, the side surface extending along the rotational axis; and a return passage which returns the gas phase cooling medium to the inside of the cooling medium flow section, the gas phase cooling medium being generated by evaporation of the liquid phase cooling medium in the region which is in the vicinity of the cooling target, by heat exchange between the liquid phase cooling medium and the cooling target

Claim (Index 1):
A rotary machine including a rotor which is rotatable around a rotational axis, and a cooling device,\n wherein the rotor includes: a hollow cooling medium flow section provided in a center portion of the rotor in a radial direction and extending along the rotational axis; and a cooling target provided outward of the cooling medium flow section in the radial direction, the rotary machine comprising: a stationary section pipe which introduces a liquid phase cooling medium generated by cooling in the cooling device into the cooling medium flow section, and returns a gas phase cooling medium present in an inside of the cooling medium flow section from the cooling medium flow section toward the cooling device, the rotor including: a leading passage which leads the liquid phase cooling medium to a region which is in the vicinity of the cooling target through a rust opening formed in a side surface of the cooling medium flow section, the side surface extending along the rotational axis; and a return passage which returns the gas phase cooling medium to the inside of the cooling medium flow section, the gas phase cooling medium being generated by evaporation of the liquid phase cooling medium in the region which is in the vicinity of the cooling target, by heat exchange between the liquid phase cooling medium and the cooling target.
