US Patent 7727414 - Heat transfer fluid using carbon nanocapsules

The increasing popularity of mini-notebooks and other portable computing devices require more processing in a smaller space resulting in a need for higher efficiency cooling solutions. This patent from Industrial Technology Research Institute teaches a carbon nanocapsule fluidic cooling solution. Claim 1 reads:

1. A heat transfer fluid with carbon nanocapsules, comprising:

a fluid; and

a plurality of carbon nanocapsules uniformly dispersed in the fluid, wherein the carbon nanocapsules are modified to bond with at least one kind of functional group, improving dispersiblity in the fluid, and

wherein the carbon nanocapsule is a polyhedral carbon cluster constituting multiple graphite layers having a balls-within-a ball structure, wherein the carbon nanocapsules are present in an amount of 0.05 to 10 parts weight, based on 100 parts by weight of the heat transfer fluid.
