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.
Scope of claims [claim1]
1. The rotor and the cooler which turn around the rotary axis and, being the rotating machine which it has,
As for the aforementioned rotor,
The refrigerant circulation section of the air which is formed to the diameter direction central part according to the aforementioned rotary axis and,
From the aforementioned refrigerant circulation section the suffering cooling body which is provided in direction outside diameter direction and, having,
The aforementioned rotating machine introduces the liquid phase refrigerant which was cooled with the aforementioned cooler into the aforementioned refrigerant circulation circles, the vapor phase refrigerant which is the aforementioned refrigerant circulation circles having the fixed part piping which is reset to the aforementioned cooling field from the aforementioned refrigerant circulation section,
As for the aforementioned rotor,
The introduction passage which leads the aforementioned liquid phase refrigerant to the vicinity of the aforementioned suffering cooling body via the 1st open part which was formed to the side which parallels to the aforementioned rotary axis of the aforementioned refrigerant circulation section and,
Heat exchange with the aforementioned suffering cooling body due to the fact that the aforementioned liquid phase refrigerant evaporates in the vicinity of the aforementioned suffering cooling body, as a result the return passage which resets the vapor phase refrigerant which is formed to the aforementioned refrigerant circulation circles and, it had, the rotating machine.
[claim2]
2. The aforementioned return passage was formed in order to reset the aforementioned vapor phase refrigerant to the aforementioned refrigerant circulation circles via the 2nd open part which was formed to the central part of one end side of the aforementioned rotary axis direction of the aforementioned refrigerant circulation section, in claim 1 the rotating machine of statement.
[claim3]
3. The aforementioned suffering cooling body plural is arranged lap by the direction of the aforementioned rotary axis,
The aforementioned introduction passage is formed in order to lead the aforementioned liquid phase refrigerant to the vicinity of each suffering cooling body via aforementioned 1st open parts of a quantity which responds to the number of aforementioned suffering cooling bodies,
The aforementioned return passage gathering and summarizing the aforementioned plural 1st passages in the plural 1st passages, and the aforementioned diameter direction central part which from adjacent each one of the aforementioned plural suffering cooling bodies are led to the diameter direction central part of the aforementioned rotor in order to be connected to the aforementioned 2nd open part, had with the 2nd passage which extends according to the aforementioned rotary axis, in claim 2 the rotating machine of statement.
[claim4]
4. The aforementioned return passage was formed, in order to form the aforementioned introduction passage and the double passage, in claim 1 the rotating machine of statement.
[claim5]
5. Length of the aforementioned rotary axis direction of the aforementioned refrigerant circulation section was formed, in order to be shorter than length of the aforementioned rotary axis direction of the aforementioned suffering cooling body, from claim 1 in either of 4 the rotating machine of statement.
[claim6]
6. The aforementioned rotor, in order to form the aforementioned introduction passage and the double passage from the aforementioned refrigerant circulation section, had the penetration prevention section in order to prevent the penetration of the aforementioned liquid phase refrigerant to the aforementioned return passage which is formed, in claim 4 the rotating machine of statement.
