Abstract

PURPOSE: To obtain a sufficient cooling effect through a miniature device by a method wherein in the device provided with two or more cooling fins, two or more cooling fins are arranged in a nonsymmetrical way so as to generate turbulent flows at the cooling door main plate.
CONSTITUTION: A rotating electrical apparatus is provided with a rotating shaft 12 as a rotor which is supported freely in rotation by means of a ring type bearing 14 and the bearing 14 is fixed in a bearing box 16. A cooling door 18 is installed on the outer periphery of the rotating shaft 12 as if it holds the bearing box 16 between its parts from the axial direction and the bearing 14 is cooled by a method wherein the cooling door 18 is rotated by being made into one body with the rotating shaft 12. The central part of the cooling door 18 is constituted with a cylindrical cooling door main plate 20 fixed to the rotating shaft 12 and two or more cooling fins 22 fitted to the main plate 20. At this time, each cooling fin 22 is fitted to the cooling door main plate 20 for example by varying the fitting angle α in the radius direction, respectively.
