Abstract
A heat transfer fluid with hetero-nanocapsules. The heat transfer fluid comprises a fluid and a plurality of hetero-nanocapsules, uniformly dispersed in the fluid, in an amount of 0.01 to 10 parts by weight, based on 100 parts by weight of the heat transfer fluid. Since the hetero-nanocapsules are apt to disperse in fluid and have superior thermal conductivity, the heat conduction capability of the heat transfer fluid therewith is enhanced.
Claims12
A heat transfer fluid with carbon nanocapsules, comprising:
- a fluid;
- and
- a plurality of hetero-nanocapsules uniformly dispersed in the fluid,
- wherein each hetero-nanocapsule is a carbon nanocapsules containing heteroatoms, comprising a closed graphite layer represented by a chemical formula C(D)x, wherein C is a carbon exhibiting sp2 hybrid orbital, D is an atom of Group III or V of the periodic table bonded to the carbon, and X is a molar equivalent from 0.0001 to 0.1, based on the molar equivalent of carbon as 1.
