Graphene-silver alloyed quantum dots nanofluid: Synthesis and application in the cooling of a simulated electronic system

In this work, graphene-silver alloyed quantum dots were synthesized by an In-situ hydrothermal method for the preparation of nanofluid suspensions at various concentrations (200-1000 ppm) and to investigate their convective cooling performance in a simulated electronic system. The prepared nanofluid exhibits high dispersion stability at pH 7 and a maximum enhancement in thermal conductivity of 45.5% (+/- 1%) was obtained for 1200 ppm nanofluid compared to water. The cooling studies show that the core temperature of the system gets decreases with an increase in Reynolds number and nanofluid concentration. The convective heat transfer coefficient and Nusselt number for 1000 ppm nanofluid enhances by 97% (+/- 2%) and 37% (+/- 1.5%) respectively compared to water. The maximum pumping power penalty of 6.2% (+/- 0.5%) was obtained for 1000 ppm nanofluid at 10 ml/sec. The enhanced thermal transport properties of alloyed quantum dot nanofluid shows their inherent capability as an advanced coolant for heat-generating electronic systems.
