Thermal management of electronic units is crucial for their efficient and longer operational life. Due to their compactness and superior thermal performance, microchannel heat sinks (MCHS) are preferred for dissipating excessive heat generated in electronic units during their operation. Literature shows that modifying the wall geometry can improve the thermal performance of the MCHS. This work uses topology optimization to find optimum material distributions of three-dimensional microchannels with different ribbed geometry. OpenFOAM is used to solve the governing and adjoint equations through continuous adjoint sensitivity analysis. The results show that the rectangular channel with an inline configuration outperforms the other cases, with a reduction in mean temperature by 22% compared to a straight channel.

摘要

Thermal management of electronic units is crucial for their efficient and longer operational life. Due to their compactness and superior thermal performance, microchannel heat sinks (MCHS) are preferred for dissipating excessive heat generated in electronic units during their operation. Literature shows that modifying the wall geometry can improve the thermal performance of the MCHS. This work uses topology optimization to find optimum material distributions of three-dimensional microchannels with different ribbed geometry. OpenFOAM is used to solve the governing and adjoint equations through continuous adjoint sensitivity analysis. The results show that the rectangular channel with an inline configuration outperforms the other cases, with a reduction in mean temperature by 22% compared to a straight channel.
