Abstract
Official abstract text for this publication.
A heat sink includes a threaded rod. The threaded rod includes a first portion and a second portion. The first portion may engage with a first heat sink fin and a second portion may engage with a second heat sink fin. The first portion includes a first external thread of a first diameter. The second portion includes a second external thread also of the first diameter and of different pitch than the first external thread. For example, the pitch of a first knurl of the threaded rod may be smaller than the pitch of a second threaded knurl of the threaded rod. The spacing of the heat sink fins may be adjusted based upon the current operating conditions of the electronic device to maintain an optimal temperature of a heat generating device during device operation.
First claim
Opening claim text (preview).
What is claimed is: 1. A heat sink comprising: a threaded rod comprising: a first portion comprising a first external thread of a first diameter; and a second portion comprising a second external thread also of the first diameter and of different pitch than the first external thread. 2. The heat sink of claim 1 , further comprising a motor that rotates the threaded rod. 3. The heat sink of claim 1 , wherein the pitch of the first external thread is smaller than the pitch of the second external thread. 4. The heat sink of claim 1 , wherein the first portion and the second portion share a same axis of rotation. 5. The heat sink of claim 4 , wherein the first portion further comprises one or more protrusions. 6. The heat sink of claim 4 , wherein the second portion comprises one or more receptacles configured to accept the one or more protrusions. 7. The heat sink of claim 1 , wherein the pitch of the first portion is the same as a first internally threaded hole of a first heat sink fin of the heat sink. 8. The heat sink of claim 7 , wherein the pitch of the second portion is the same as a second internally threaded hole of a second heat sink fin of the heat sink. 9. The heat sink of claim 1 , wherein the first external thread engages with a first internally threaded hole of a first heat sink fin of the heat sink. 10. The heat sink of claim 9 , wherein the second external thread engages with a second internally threaded hole of a second heat sink fin of the heat sink.
