Investigation of heat transfer through shark fin inspired bionic pattern in a micro-channel

Abstract Integrated circuits have seen an astronomical expansion in the number of transistors following Moore’s Law over the last few decades. The limitations of air cooling motivate the search for new improvised heat exchanger systems and design modifications in existing heat channels for enhanced heat flux dissipation. Performance of the bionic fins is analyzed using computational fluid dynamics. A laminar model is established to analyze the heat transfer performance of fins in Ansys Fluent. The performance results are calculated in comparison with rectangular and elliptical geometries by varying pressure and heat flux. Though shark fins have a heat transfer coefficient coinciding with elliptical wedges, the denticles’ surface area has more than 10% higher surface area. The shark fins’ surface temperature remains 0.83% lower than elliptical wedges and 3.8% lower than rectangles. The shark fin-inspired bionic pattern is observed to have better uniform temperature distribution and heat dissipation compared to conventional geometries.
