Abstract

Particular embodiments described herein provide for an electronic device that can be configured to include a vapor chamber and means of attachment for the vapor chamber. The vapor chamber can include one or more columns, where at least a portion of the columns include fiber braids and one or more wicks. At least one of the wicks can also include the fiber braids. The columns can be braised to a top plate or a bottom plate of the vapor chamber. The vapor chamber can be secured over a heat source using a vapor chamber securing means that can include spring arms. The spring arms can bend, flex, rotate, etc. to absorb some of the force when vapor chamber is secured over the heat source.

Claims

1. A vapor chamber comprising:

one or more columns, wherein at least a portion of the one or more columns include fiber braids; and

one or more wicks.

2. The vapor chamber of claim 1, wherein at least one of the one or more wicks of the vapor chamber include the fiber braids.

3. The vapor chamber of claim 1, wherein the fiber braids are made of copper fiber or titanium fiber.

4. The vapor chamber of claim 1, wherein the one or more columns of the vapor chamber are brazed to a bottom plate of the vapor chamber.

5. The vapor chamber of claim 1, wherein the one or more columns of the vapor chamber are brazed to a top plate of the vapor chamber.

6. The vapor chamber of claim 1, wherein a portion of the one or more columns of the vapor chamber are support columns and the support columns do not include the fiber braids.

7. A device comprising:

one or more heat sources; and

a vapor chamber over the one or more heat sources, wherein the vapor chamber includes fiber braids.

8. The device of claim 7, wherein one or more columns of the vapor chamber include the fiber braids.

9. The device of claim 7, wherein one or more wicks of the vapor chamber include the fiber braids.

10. The device of claim 7, wherein the fiber braids are made of copper fiber or titanium fiber.

11. The device of claim 7, wherein one or more columns of the vapor chamber include the fiber braids and the columns are brazed to a bottom plate of the vapor chamber.

12. The device of claim 7, wherein one or more columns of the vapor chamber include the fiber braids and the columns are brazed to a top plate of the vapor chamber.

13. The device of claim 7, wherein one or more columns of the vapor chamber and one or more wicks of the vapor chamber include the fiber braids.

14. The device of claim 7, wherein one or more columns of the vapor chamber are support columns and the support columns do not include the fiber braids.

15. A method for creating a vapor chamber, the method comprising:

creating one or more columns for the vapor chamber from a fiber braid by cutting the fiber braid; and

brazing the created one or more columns to a top plate or a bottom plate to create at least a portion of the columns for the vapor chamber.

16. The method of claim 15, further comprising:

creating one or more wicks for the vapor chamber from the fiber braid.

17. The method of claim 15, wherein the fiber braid was created before creating the vapor chamber.

18. The method of claim 15, wherein the fiber braid is made of copper fiber or titanium fiber.

19. The method of claim 15, further comprising:

creating one or more support columns for the vapor chamber, wherein the support columns do not include the fiber braid; and

securing the one or more support columns to the top plate or the bottom plate.

20. The method of claim 15, further comprising:

securing the top plate to the bottom plate to create the vapor chamber.
