First Claim
Patent Images
1. A voltage controller, comprising:
- a control circuit which controls a voltage of electric power generated in an alternator of a vehicle while generating heat; and
a heat radiating member, having a first surface and a second surface, which receives the heat from the control circuit through the first surface and radiates the received heat from the second surface, wherein the second surface of the heat radiating member is formed in a smooth shape.

Abstract
A voltage controller has a control circuit and a heat radiating member attached to the circuit. The circuit controls a voltage of electric power generated in an alternator of a vehicle while generating heat. The member has a first surface and a second surface. The second surface of the member is formed in a smooth shape having no protrusions or hollows. A cooling wind flows on the second surface. The member receives the heat from the control circuit through the first surface and radiates the heat from the second surface to the wind.

11. An electric rotary machine, comprising:
-
an electromagnetic interaction unit, having a stator and a rotor, which electromagnetically induces electric power in the stator from a rotational force of the rotor or electromagnetically converts electric power supplied to the stator to a rotational force of the rotor and outputs the induced electric power or the converted rotational force;
a control unit which controls the electromagnetic interaction unit to output the induced electric power or the converted rotational force set at a predetermined value, and generates heat during the control of the electromagnetic interaction unit; and
a heat radiating member, having a first surface and a second surface, which receives the heat from the control unit through the first surface and radiates the received heat from the second surface, wherein the second surface of the heat radiating member is formed in a smooth shape. - View Dependent Claims (12, 13, 14)
