Sandwiched thermal article
A thermal material for heat dissipation, which includes at least one sheet of flexible graphite sandwiched about a non-graphite core layer.
1 . A thermal dissipation article, comprising at least two sheets of graphite sandwiched about a core layer, capable of use for thermal dissipation.
2 . The article of claim 1 , wherein the core layer comprises materials selected from the group consisting of plastics, metals, and composites or combinations thereof.
3 . The article of claim 2 , wherein the core layers comprises a metallic material.
4 . The article of claim 3 , wherein the metallic material is tanged or a mesh.
5 . The article of claim 3 , wherein the core layer comprises aluminum.
6 . The article of claim 1 , wherein a portion of the core layer extends beyond an edge of at least one of the sheets of graphite.
7 . The article of claim 1 , further comprising a heat collection article with which the article is in operative contact.
8 . The article of claim 7 , wherein the heat dissipation device comprises a heat sink, a heat pipe, a heat plate or any combination thereof.
9 . The article of claim 1 , which is in operative contact with a heat source.
10 . The article of claim 9 , wherein the core layer is in direct operative contact with the heat source.
11 . The article of claim 1 , which has an in-plane thermal conductivity of at least about 140 W/m° K.
12 . The article of claim 11 , which has a through-plane thermal conductivity of no greater than about 12 W/m° K.
13 . A finstock for an electronic device thermal dissipation system, comprising a core layer sandwiched between at least two sheets of graphite.
14 . The finstock of claim 13 , wherein the core layer comprises materials selected from the group consisting of plastics, metals, and composites or combinations thereof.
15 . The finstock of claim 14 , wherein the core layer comprises a metallic material.
16 . The finstock of claim 15 , wherein the metallic material is tanged or a mesh.
17 . The finstock of claim 13 , wherein a portion of the core layer extends beyond an edge of at least one of the sheets of graphite.
18 . The finstock of claim 15 , wherein the core layer comprises aluminum.
19 . The finstock of claim 13 , which has an in-plane thermal conductivity of at least about 140 W/m° K.
20 . The finstock of claim 19 , which has a through-plane thermal conductivity of no greater than about 12 W/m° K.
