Abstract
A heat sink assembly includes a block formed of a thermally conductive material. For example, the thermally conductive material includes thermally conductive polymer. A heat conduit (e.g., a heat pipe) extends through a substantial portion of the block. In one example arrangement, airflow channels extend through portions of the block.
Claims6
A heat sink assembly comprising:
- a heat conduit;
- a block formed of a thermally conductive non-metallic material having a first thermal conductivity,
- the heat conduit extending through a substantial portion of the block,
- the heat conduit having a second thermal conductivity greater than the first thermal conductivity,
- wherein the block has a first segment on one side of a portion of the heat conduit, and the block has a second segment on another side of the portion of the heat conduit,
- the first segment having a first heat conduction distance to dissipate heat from the heat conduit, and the second segment having a second heat conduction distance to dissipate heat from the heat conduit;
- and
- a second heat conduit extending through another substantial portion of the block,
- wherein the block has a third segment on one side of a portion of the second heat conduit, and the block has a fourth segment on another side of the portion of the second heat conduit,
- the third segment having a third heat conduction distance to dissipate heat from the second heat conduit, and the fourth segment having a fourth heat conduction distance to dissipate heat from the second heat conduit.

A system comprising:
- a component;
- and
- a heat sink thermally contacted to the component,
- the heat sink having a block formed of a thermally conductive non-metallic material, the heat sink having a first segment and a second segment,
- the heat sink further having a heat conduit extending through the block between the first and second segments, the first segment to transfer heat away from the heat conduit in a first direction, and the second segment to transfer heat away from the heat conduit in a second direction,
- wherein the block further has a third segment and a fourth segment, the heat sink further having a second heat conduit extending between the third and fourth segments.
