Abstract

A docking station or portable information handling system processing component dissipates excess thermal energy through a glass ceramic heat sink disposed in a housing and interfaced with the processing component by a liquid metal embedded elastomer and elastic graphene. For example, plural pieces of glass ceramic material are each coated in graphene and vertically stacked in the housing thermally interfaced with each other by the liquid metal embedded elastomer having the elastic graphene coupled against the graphene coating to exchange thermal energy.

Claims (22)

1. An information handling system docking station comprising:

a housing;

a circuit board disposed in the housing;

one or more processing components coupled to the circuit board and operable to process information;

plural ports coupled to the circuit board and interfaced with the one or more processing components, each port of the plural ports operable to couple with a cable to interface with an external device;

plural heat sinks, each heat sink of the plural heat sinks having a piece of glass material coated with graphene and interfaced with the one or more processing components to dissipate thermal energy from the one or more processing components, a first heat sink of the plural heat sinks and a second heat sink of the plural heat sinks vertically stacked and separated by a gap of air; and

a thermal elastomer directly interfacing the first heat sink, the second heat sink, and the one or more processing components, the thermal elastomer having an embedded elastic graphene wavy channel.

2. The information handling system docking station of claim 1 wherein the thermal elastomer further comprises a liquid metal embedded elastomer thermally interfacing the one or more processing components and the piece of glass material in the first heat sink and in the second heat sink.

3. The information handling system docking station of claim 2 wherein the liquid metal embedded elastomer comprises silicon embedded with liquid phase eutectic gallium indium.

4. The information handling system docking station of claim 1 wherein the piece of glass material coated with graphene in the plural heat sinks comprises a glass ceramic material.

5. The information handling system docking station of claim 2 wherein the embedded elastic graphene wavy channel is coupled to the liquid metal embedded elastomer and is in contact with the first heat sink and the second heat sink.

6. The information handling system docking station of claim 5 wherein the liquid metal embedded elastomer comprises silicon embedded with liquid phase eutectic gallium indium.

7. The information handling system docking station of claim 6 wherein the one or more processing components comprise a graphics processor.

8. An information handling system docking station comprising:

a housing;

a circuit board disposed in the housing;

one or more processing components coupled to the circuit board and operable to process information;

plural heat sinks, each heat sink of the plural heat sinks having a glass piece coated with graphene; and

a liquid metal embedded elastomer thermally interfacing the glass piece of the plural heat sinks and configured to thermally couple with a processing component of the one or more processing components, a first heat sink of the plural heat sinks and a second heat sink of the plural heat sinks vertically stacked and separated by a gap of air;

wherein the liquid metal embedded elastomer directly interfaces the first heat sink, the second heat sink, and the one or more processing components, the liquid metal embedded elastomer having embedded elastic graphene formed as a wavy channel.

9. The information handling system docking station of claim 8 wherein the liquid metal embedded elastomer comprises silicon embedded with liquid phase eutectic gallium indium.

10. The information handling system docking station of claim 9 wherein the glass piece of the plural heat sinks comprises glass ceramic material.
