COOLING SYSTEM AND METHOD OF POWER-GENERATOR

摘要

The purpose of the present invention is to improve the cooling performance of a power generation apparatus by facilitating the cooling of a cooling fluid. A generator cooling system according to the present invention comprises a rotary shaft connected to a turbine, and rotated along with the turbine; a rotor coupled to the central portion of the rotary shaft, and able to rotate along with the rotary shaft; a cylindrical stator positioned outside the rotational radius of the rotor; a cooling fluid inlet into which a cooling fluid flows, and a cooling fluid outlet from which the cooling fluid is discharged; and a housing is arranged between the cooling fluid inlet and the cooling fluid outlet to form a cooling flow path, wherein the stator has a sub cooling flow path which is formed to penetrate from the inner circumferential surface thereof to the outer circumferential surface thereof, allows the cooling fluid flowing into a space between the stator and the rotor to pass through the stator and to flow to the cooling fluid outlet, and forms one path of the cooling flow path.
