Heat sink for enhanced heat dissipation
View Patent ↗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.
1. 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.
2. The heat sink assembly of claim 1 , wherein the first and second heat conduction distances are substantially the same.
3. The heat sink assembly of claim 1 , wherein each of the first, second, third, and fourth segments have airflow channels extending therethrough.
4. 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.
5. The system of claim 4 , wherein the thermally conductive material comprises thermally conductive polymer.
6. The system of claim 4 , wherein the heat conduits comprise heat pipes.
