Abstract

A heat sink is porcelainized and then has conductive circuitry, resistors and capacitors or other circuit elements added, as required. These are applied directly onto the heat sink and become an integral part of it.

Porcelainized Heat Sink Assembly

A heat sink is porcelainized and then has conductive circuitry, resistors and capacitors or other circuit elements added, as required. These are applied directly onto the heat sink and become an integral part of it.

Referring to Figs. 1 and 2, heat sink 1 is fabricated from steel, aluminum or other metals of various thicknesses and in any suitable configuration depending on users' requirements. The heat sink can be punched or drilled, as at 2, using standard machine tools, for mounting components or for plated through holes and for circuitry after porcelainizing. A porcelainized or insulating coating may be applied over the entire heat sink or any portion, such as portions 3-5.

Conductive circuit 6 is then applied to the porcelainized surfaces, as required. Components such as resistor 7 or capacitor 8 are then installed.

The steel of the heat sink acts as a thermal path to remove the heat from electrical components. The porcelain serves as an insulator to insulate components and circuitry from grounding or shorting to the steel where insulation is needed.

The conductive circuitry, resistors, capacitors or other components may be applied to the heat sink be screening them on or by any suitable process. They may be cured or hardened to the heat sink by firing or other methods.
