Abstract

PURPOSE: To increase the cooling effect while ventilating the base of a heat radiating fin by supplying rotor at one end with a fin supporter having grooves in an axial direction on which the plural number of heat radiating fins are installed at regular intervals.
CONSTITUTION: A heat pipe 35 is provided inside the axis of rotation 33, and the fin supporter 36 having the ventilating groove 39 in an axial direction is mounted on the axis of rotation at one end, and the plural number of heat radiating fins 37 are mounted on the periphery of the fin supporter 36 at regular intervals. By so doing, the cool air from a fan 46 installed near the end of the axis passes through a ventilating channel 39 of the fin supporter 36, and the air is sent from the base of the fin 37 to the periphery. As a result, the total area of the heat radiating fin 37 is effectively utilized, so that the cooling effect can be improved.
