Summary: | The urge for more complicated, sophisticated electrically active heat transfer devices, has intensified nowadays thus requiring a more critical thermal management issue. The generation of higher heat flux needs to be tackled efficiently as to avoid performance deterioration to the devices. The conventional active heat transfer method alone has limitations, especially in terms of space. This paper studies the effect of Al2O3:SiO2 hybrid nanofluids with 0.5% volume concentration in water as an alternative coolant in a single cooling plate. Five different ratios of hybrid Al2O3:SiO2 nanofluids were investigated ranging from 10:90 to 50:50 (Al2O3:SiO2) mixture ratio. Two types of cooling plates were studied which were Serpentine and Distributor type cooling plates. These plates were fabricated from carbon graphite which is commonly used in a liquid-cooled Proton Exchange Membrane Fuel Cell (PEMFC). In conclusion, the R1 (10:90) Al2O3:SiO2 hybrid nanofluids were shown as the most prominent ratio in heat transfer improvement and Serpentine shows the most feasible cooling plate with higher convective heat transfer and lower pumping power than the Distributor plate. |
