Abstract
In one embodiment, a thermal management device includes a heat sink base and heat sink fins comprising a single element formed from a plurality of graphene layers with carbon nanotubes interposed between the graphene layers. A method is also disclosed herein.
Claims20
A method comprising:
- creating an element comprising a plurality of graphene layers and carbon nanotubes interposed between the plurality of graphene layers;
- removing material from the element to define a heat sink that includes heat sink fins integrated with a heat sink base;
- and
- positioning the heat sink on an integrated circuit package such that the heat sink is in direct contact with the integrated circuit package.
1 more element
A thermal management device comprising:
- a heat sink base comprising a first plurality of graphene layers with first carbon nanotubes interposed between the first plurality of graphene layers;
- and
- heat sink fins, each heat sink fin comprising a second plurality of graphene layers with second carbon nanotubes interposed between the second plurality of graphene layers,
- wherein the heat sink base and the heat sink fins comprise a heat sink that is positioned on an integrated circuit package such that the heat sink is in direct contact with the integrated circuit package.
1 more element
An apparatus comprising:
- a printed circuit board;
- an integrated circuit package mounted on the printed circuit board;
- and
