Nowadays, electronic components are one of the essential parts almost every smart device. To efficiently transfer desired amount heat, recent studies have focused on investigating potential advanced thermal coolants and heat sink configurations. Current study reveals novel water-based hybrid nanofluid silica (SiO2) ferric oxide (Fe2O3) for cooling high-heat-generating devices. The experimental work was conducted to inspect characteristics a uniquely designed staggered oriented airfoil shaped pin-fin employing Fe2O3-SiO2 with different mixture ratios (25%:75%), (50%:50%), (75%:25%). Airfoil pin-fins offer less resistance fluid flow maximum effective area due their unique shape delayed separation at rear end. All were tested three heating powers (75, 100, 125 W) varying Reynolds number in laminar regime. Experimental results revealed that having ratio 50:50 showed least followed by 25:75 75:25. Maximum enhancement 17.65% average Nusselt observed against power 75W. Pumping found increase supplementation nanoparticles base fluid, while little variation among ratios. Finally, compared recently published studies, which fins better flow.
