- 13. The method recited in claim 12 and further comprising:
inserting a thermal plug into the cavity.
- 14. The method recited in claim 13, wherein the thermal plug comprises copper.
- 15. A method comprising:
forming from thermally conductive metal a plurality of fins extending outwardly from a core in an asymmetric pattern, the core having a central axis, each fin having a base coupled to the core substantially parallel to the central axis.
- 16. The method recited in claim 15, wherein the fins are formed curved, the method comprising:
bending a portion of each fin in substantially the same relative direction.
- 17. The method recited in claim 16, wherein before bending the method comprises:
separating the portion of each fin from the core.
- 18. The method recited in claim 17, wherein separating comprises:
forming a cavity or channel in the core a predetermined distance along the central axis.
- 19. The method recited in claim 15, wherein the fins are formed straight, the method comprising:
bending a portion of each fin in substantially the same relative direction.
- 20. The method recited in claim 19, wherein before bending the method comprises:
separating the portion of each fin from the core.
- 21. The method recited in claim 20, wherein separating comprises:
forming a cavity or channel in the core a predetermined distance along the central axis.
- 22. A method of making a heat sink comprising:
forming a core having a central axis and a surface to thermally contact a heat-generating component; and forming from thermally conductive metal a plurality of fins extending outwardly from the core, each fin having a base and a tip, wherein the bases are coupled to the core substantially parallel to the central axis, wherein the tips define the periphery of a face to face the component, and wherein the face comprises inter-fin openings.
- 23. The method recited in claim 22, wherein the fins are formed curved, the method comprising:
bending a portion of each fin in substantially the same relative direction.
- 24. The method recited in claim 23, wherein before bending the method comprises:
separating the portion of each fin from the core.
- 25. The method recited in claim 24, wherein separating comprises:
forming a cavity or channel in the core a predetermined distance along the central axis.
- 26. The method recited in claim 22, wherein the fins are formed straight, the method comprising:
bending a portion of each fin in substantially the same relative direction.
- 27. The method recited in claim 26, wherein before bending the method comprises:
separating the portion of each fin from the core.
- 28. The method recited in claim 27, wherein separating comprises:
forming a cavity or channel in the core a predetermined distance along the central axis.
