Abstract
A thermal pad for use in facilitating heat flow between a heat source surface and a heat sink surface includes a carbon fiber fabric that is impregnated with a thermal substance.
Claims33
A heat transfer structure for placement between two opposing surfaces to facilitate heat transfer between the surfaces, comprising:
- a fabric having a high carbon fiber content, wherein said fabric includes at least 50 percent carbon fiber by weight;
- and
- a thermally conductive thermal substance impregnating said fabric.
An electrical apparatus comprising:
- an electrical component that generates heat when in an operative condition;
- a heat sink that is capable of absorbing heat applied to a surface thereof;
- and
- a heat transfer pad disposed between said electrical component and said heat sink to facilitate heat flow therebetween, said heat transfer pad including:
- a fabric having a high carbon fiber content, wherein said fabric includes at least 50 percent carbon fiber by weight;
- and
- a thermally conductive thermal substance impregnating said fabric.
4 more elements
A method for use in assembling an electrical apparatus, comprising:
- providing an electrical component;
- providing a heat sink;
- providing a heat transfer pad having a fabric with a high carbon fiber content that is impregnated with a thermally conductive thermal substance, wherein said fabric, without the thermally conductive thermal substance, includes at least 50 percent carbon fiber by weight;
- placing said heat transfer pad between said electrical component and said heat sink;
- and
- applying pressure to partially compress said heat transfer pad between said electrical component and said heat sink.
3 more elements
