Abstract

A passive thermal heat-pipe material comprising an optical mounting structure including heat producing electronic components is provided. Each structural component of the optical mounting structure may be at least partially comprised of a polymer including a plurality of carbon nanoparticles. In a further aspect, a method of creating an optical structure adapted to support a plurality of heat emitting components is provided. The method includes adding a percentage by concentration of carbon nanoparticles to a polymer base material, mixing the polymer base material and carbon nanoparticles uniformly, melting the mixture at high temperature, forming the melted mixture into a component of the optical structure, and cooling the formed component to solidify the component. The percentage may be between 2 and 10 percent.

First claim

What is claimed is:

1. A wearable device, comprising:
a first portion of a frame configured to be worn over eyes of a wearer and having an optical mounting structure, the first portion including a heat producing electronic component within an interior of the first portion;
temple arms extending away from the first portion and configured to be worn over ears of the wearer such that an inner surface of an individual temple arm faces the wearer and an outer surface of the individual temple arm faces away from the wearer, the individual temple arm at least partially comprising a polymer including carbon nanoparticles; and
a graphite layer thermally bonded to the outer surface of the individual temple arm, a portion of the graphite layer extending from the outer surface of the individual temple arm into the interior of the first portion and into contact with the electronic component to conduct heat from the electronic component to the outer surface of the individual temple arm.

2. The wearable device of claim 1 wherein both temple arms include a graphite layer bonded to the outer surface, the graphite layer thermally coupled to the electronic component.

3. The wearable device of claim 1 wherein the graphite layer comprises a sheet of pyrolytic graphite bonded to the outer surface of the individual temple arm with a thermally conductive bonding material.

4. The wearable device of claim 1 wherein the carbon nanoparticles include any one or more of single layer graphene, bilayer graphene, few layer graphene, multilayer graphene, and carbon nanotubes.

5. The wearable device of claim 1 wherein the polymer includes carbon nanoparticles in an amount in a range between 2-10 percent by concentration in the polymer.

6. The wearable device of claim 5 wherein the polymer includes carbon nanoparticles in an amount in a range between 2-4 percent by concentration in the polymer.

7. The wearable device of claim 1 wherein the carbon nanoparticles are carbon nanotubes.

8. The wearable device of claim 1 wherein the carbon nanoparticles are pyrolytic graphite flakes.

9. A head mounted display, comprising:
a first portion of a frame adapted to support an electronic component and one or more display optical systems;
temple arms extending away from the first portion and configured to be worn over ears of a wearer of the head mounted display; and
a graphite layer thermally bonded to an outer surface of an individual temple arm, a portion of the graphite layer extending from the outer surface of the individual temple arm into an interior of the first portion of the frame and into contact with the electronic component to conduct heat from the electronic component to the outer surface of the individual temple arm.

10. The head mounted display of claim 9 wherein the individual temple arm is thermally coupled to the electronic component.

11. The head mounted display of claim 10 wherein the individual temple arm at least partially comprises a polymer and the polymer includes carbon nanoparticles in an amount in a range between 2-10 percent by concentration in the polymer.

12. The head mounted display of claim 11 wherein the individual temple arm at least partially comprises a polymer and the polymer includes carbon nanoparticles in an amount in a range between 2-4 percent by concentration in the polymer.

13. The head mounted display of claim 12 wherein the carbon nanoparticles are any one or more of single layer graphene, bilayer graphene, few layer graphene, multilayer graphene, and carbon nanotubes.

14. The head mounted display of claim 9 wherein both of the temple arms include a graphite layer bonded to outer surfaces and extending into the interior of the first portion of the frame.
