Patent ID: 7147045

Claim:
A cooling system for removal of heat from at least one heat generating component, the cooling system comprising: a generally planar portion for positioning substantially near said at least one heat generating component; a low-profile extrusion having an inner and outer external surface and having a first sealed end and a second sealed end, said low-profile extrusion including said generally planar portion and being curved upon itself into a generally toroidal shape such that said second sealed end is disposed generally opposite said first sealed end, wherein said first sealed end and said second sealed end are oriented opposite from said generally planar portion; and wherein the low-profile extrusion includes a first arcuate portion extending from the generally planar portion to the first sealed end, and a second arcuate portion extending from the generally planar portion to the second sealed end, the first arcuate portion and the second arcuate portion forming segments of a generally circular body portion, each of the first arcuate portion and the second arctuate portion having the same generally constant arc radius measured from a common focus point central to the generally circular body portion; an interior space formed by said inner external surface of said low-profile extrusion; said low-profile extrusion having an external surface adapted for thermal connection to said at least one heat generating component; a plurality of micro-tubes formed in the interior of said low-profile extrusion and adapted for containing a heat transfer fluid inside the micro-tubes; and a fin structure in thermal connection with the exterior surfaces of said extrusion.
