Abstract
A novel fluid heat transfer agent suitable for use in a closed heat transfer system, for example, wherein energy is transferred between an evaporator and a condenser in heat exchange relationship with the heat transfer agent that is caused to flow from one to the other. The novel heat transfer agent is a complex comprising a body of heat transfer fluid, for example, ethylene glycol or water, having suspended therein carbon nanoparticles in a quantity sufficient to enhance the thermal conductivity of the body of heat transfers fluid, per se. The carbon nanoparticles are selected from carbon in the form of sp type and sp type bonding and preferably comprise nanotubes or fullerenes and may have a coupling agent bonded thereto or enclosed therein when the nanotube or fullerene forms a hollow capsule. The coupling agent may be a polar organic group covalently bonded to the carbon nanoparticles and miscible in the fluid medium.
