Nanofluid is employed as working medium for conventional circular heat pipe. The nanofluid used in the present study is an aqueous solution of various-sized gold nanoparticles. The thermal resistance of heat pipe with nanofluid or with DI water was measured. The heat pipe was designed as a heat spreader for CPU in a notebook or a desktop PC. At a same charge volume, there is a significant reduction in thermal resistance of heat pipe with nanofluid as compared with DI water. The measured results also show that the thermal resistance of a vertical meshed heat pipe varies with the size of gold nanoparticles.
