Abstract: This study focuses on assessing the cooling capabilities of microchannels with different cross-sectional geometries for electronic devices. The use of nano coolant and computational fluid dynamics (CFD) research advances microchannel cooling technology, making electronic equipment more reliable and lasting longer. The technique uses computational fluid dynamics (CFD) models of microchannels with different cross-sections, cooled by Al2O3 nano coolant. The fluid flow behavior and heat transfer properties in the microchannels are studied by running simulations. The CFD results are validated compared to prior experimental and numerical investigations. Parameters including temperature distribution, pressure drop, and heat transfer rate are evaluated to determine the optimal cross-sectional shape for heat removal. Key findings include the trapezoidal cross-section demonstrating the highest heat transfer rate among the defined geometries, and circular microchannels exhibiting optimal performance when hydraulic diameters reach 500 µm and heat carrying capacities are 150 W/cm2, while maintaining a Reynolds number of 650. The study presents groundbreaking observations regarding the impact of cross-sectional geometry on heat transfer efficiency in microchannel cooling systems.
