NANO CARBON MATERIALS FOR ENHANCING THERMAL TRANSFER IN FLUIDS

Title:

NANO CARBON MATERIALS FOR ENHANCING THERMAL TRANSFER IN FLUIDS

Document Type and Number:

WIPO Patent Application WO2003004944

Kind Code:

A3

Abstract:

A novel fluid heat transfer agent suitable for use in a closed heat transfer system, for example, wherein heat 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<2> type and sp<3> 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.
