Stability of Al2O3-water Nanofluid for Electronics Cooling System

For stability of nanofluid need to study, before going to passed it through the electronic device. Because need to more stability of nanofluid and avoid the sedimentation and clogging substance of nanofluid. Stability effect on rectangular shape minichannel heat sink is experimentally investigated for electronics cooling using nanofluids as coolants instead of water. Al2O3-water nanofluids with 0.10 to 0.25 vol. % of nanoparticle was used as coolants. From experiment result, final particle cluster size, microstructure, zeta potential, sedimentation, Transmission Electron microscope and photo capture method analyze for stability purpose. Shown the 0.10 vol. % was better performance on electronic cooling system respect of stability.
