<p>Provided is a heat transfer fluid, which uses hetero atom-containing carbon nanocapsules having improved dispersibility in water and high thermal conductivity, and thus has improved thermal conductivity. The heat transfer fluid comprises a fluid, and a great number of hetero atom-containing carbon nanocapsules dispersed uniformly in the fluid. The hetero atom-containing carbon nanocapsules are present in an amount of 0.01-10 parts by weight per 100 parts by weight of the heat transfer fluid. The hetero atom-containing carbon nanocpasules comprise closed graphite layers represented by the formula of C(D)x, wherein C is carbon showing an sp^2 hybridized orbital, and D is a Group 3 or 5 element bound to carbon atom and having a molar equivalent of 0.0001-0.1 per molar equivalent of carbon.</p> |
