Abstract

Particular embodiments described herein provide for an electronic device that can be configured to include a vapor chamber that includes ionized fluid and an adjustable polarization layer coupled to the vapor chamber. The adjustable polarization layer can be used to direct a flow of the ionized fluid in the vapor chamber towards one or more heat sources. In some examples, the ionized fluid is ionized water and the adjustable polarization layer is polyester (PET) film that includes a plurality of electrode stripes.

First claim

What is claimed is:

1. An electronic device comprising:
a vapor chamber that includes ionized fluid; and
an adjustable polarization layer coupled to the vapor chamber, wherein the adjustable polarization layer can direct a flow of the ionized fluid in the vapor chamber.

2. The electronic device of claim 1 , wherein the ionized fluid is ionized water.

3. The electronic device of claim 1 , wherein the adjustable polarization layer is a polyester (PET) film that includes a plurality of electrode stripes.

4. The electronic device of claim 3 , wherein the PET film has a thickness equal to or less than about 0.2 millimeters.

5. The electronic device of claim 1 , further comprising:
a first heat source and a second heat source under the vapor chamber, wherein the adjustable polarization layer is between the vapor chamber and the first heat source and the second heat source.

6. The electronic device of claim 5 , wherein the adjustable polarization layer is biased to direct the flow of the ionized fluid in the vapor chamber to the first heat source.

7. The electronic device of claim 1 , wherein the adjustable polarization layer is located on a bottom portion of the vapor chamber and at least a portion of one or more sides of the vapor chamber.

8. A device comprising:
one or more heat sources;
a vapor chamber over the one or more heat sources, wherein the vapor chamber includes ionized fluid;
an adjustable polarization layer coupled to the vapor chamber and between the vapor chamber and the one or more heat sources, wherein the adjustable polarization layer includes an array of electrodes that can be used to direct a flow of the ionized fluid in the vapor chamber; and
a polarizing engine to positively bias one or more first portions of the adjustable polarization layer and to negatively bias one or more second portions of the adjustable polarization layer.

9. The device of claim 8 , wherein the ionized fluid is ionized water.

10. The device of claim 8 , wherein at least a portion of the positively biased one or more first portions of the adjustable polarization layer is over a first heat source from the one or more heat sources and at least a portion of the negatively biased one or more second portions of the adjustable polarization layer is over a second heat source from the one or more heat sources.

11. The device of claim 10 , wherein the polarizing engine causes at least a portion of the positively biased one or more first portions of the adjustable polarization layer over the first heat source to change to a negative bias and causes at least a portion of the negatively biased one or more second portions of the adjustable polarization layer over the second heat source to change to a positive bias.

12. The device of claim 8 , wherein the adjustable polarization layer has a thickness equal to or less than about 0.2 millimeters.

13. The device of claim 8 , wherein the adjustable polarization layer is a polyester (PET) film that includes a plurality of electrode stripes.

14. The device of claim 13 , wherein the PET film has a thickness between about 0.1 millimeters and about 0.5 millimeters.

15. A method comprising:
determining a workload of a heat source under a vapor chamber that includes an ionized fluid; and
changing a bias of an adjustable polarization layer coupled to the vapor chamber when the workload of the heat source causes or will cause the heat source to be above a temperature threshold, wherein the adjustable polarization layer is used to direct a flow of the ionized fluid in the vapor chamber towards the heat source.

16. The method of claim 15 , further comprising:
determining a second workload of a second heat source under the vapor chamber; and
changing the bias of at least a portion the adjustable polarization layer when the second workload of the second heat source causes or will cause the second heat source to be above a second temperature threshold, wherein the adjustable polarization layer is used to direct the flow of the ionized fluid in the vapor chamber towards the second heat source.

17. The method of claim 15 , wherein the ionized fluid is ionized water.

18. The method of claim 15 , wherein the adjustable polarization layer is an array of electrode stripes.

19. The method of claim 15 , wherein the adjustable polarization layer is a polyester (PET) film that includes a plurality of electrode stripes.

20. The method of claim 19 , wherein the PET film has a thickness between about 0.1 millimeters and about 0.5 millimeters.
