ABSTRACT:
A heat dissipating and mounting structure for an electrical circuit includes a disc which is mounted to a rotatable shaft. The disc extends outward from the shaft to present a front surface upon which the circuit is mounted and a rear surface upon which cooling fins are formed. A pair of openings are formed in the disc and cooling air flows through them when the shaft rotates. The cooling fins are rotated through the air flowing through the disc openings and heat generated by the electrical circuit is carried away with little temperature rise and minimal disturbance of the air flow.
