Abstract

PURPOSE: To elevate heat transfer efficiency by a method wherein a fluid heat transfer medium is used for the heat transfer between members to one of which a heat pipe is employed and a magnetic fluid seal is used for prevention of this heat transfer medium from leaking.
CONSTITUTION: For the purpose of radiating heat of the rotary spindle 11 of an electric motor consisting of a magnet 9 and an armature coil 10, etc., the rotary spindle 11 is made of the heat pipe and the heat generated at the coil 10 and bearing portions 12, 13 is transferred to the end portion 11a of the rotary spindle. Since this end portion 11a is projected into the magnetic fluid 21 sealed in a clearance portion composed of a york 17 with a convex edge 18, a permanent magnet 16 and an inside of a housing 14, the heat is transferred to the end portion 20a of the fixed heat pipe 20 through the magnetic fluid 21. Then the heat is radiated on a radiating portion 20b which provides fins 22 at the other end of the heat pipe 20 to cool the rotary spindle 11 of the electric motor, and the like.
