http://www.freepatentsonline.com/7927992.html

This latest patent from the nanotube electronics pioneer Nantero includes some basic claims to using carbon nanotubes for cooling electronic circuitry. Claim 1 reads:

1. A method of cooling a circuit element, the method comprising:

providing a thermal reservoir having a temperature lower than an operating temperature of the circuit element; and

providing a nanotube article in thermal contact with the circuit element and with the reservoir, the nanotube article comprising a non-woven fabric of nanotubes in contact with other nanotubes to define a plurality of thermal pathways along the article,

the nanotube article having a nanotube density and a shape selected such that the nanotube article is capable of transferring heat from the circuit element to the thermal reservoir.
