Abstract
Preparation of water nano-droplet or silver nanoparticle/nanowire dispersed perflurocarbon 3M Novec HFC-7100 (FC) base nanofluid has been developed for heat transfer enhanement of FC fluid. The good dispersion stability of water-droplet dispersed FC nanofluid was maintained for over 6 months by addition of organic additives into HFC-7100, and the water droplet diameters of FC nanofluid were around 100-150 nm, which can be controlled of additives/water molar ratio. Also, silver nanoparticle dispersed HFE-7x00 base FC nanofluid can be obrained by using surface modification technique. It was found that thermal conductivities of obtained water nano-droplet dispersed FC-nanofluids were increased around 10 % comparing with the base fluids. Heat transfer enhancement could be achieved by using the FC nanofluid as single-phase heat transfer cooling fluid for mock lack-mount PC server liquid cooling.
