On conjugate heat transfer in microchannel heat sinks
International Journal of ThermofluidsThis work aims to study the anisotropic thermal impacts of employing liquid metal fluids including Na and NaK as coolants in two metallic microchannel heat sinks. The two studied microchannel heat sinks have aspect ratios of 1 and 2 while their hydraulic

Microchannel Heat Sinks—A Comprehensive Review
Electronic MaterialsAn efficient cooling system is necessary for the reliability and safety of modern microchips for a longer life. As microchips become smaller and more powerful, the heat flux generated by these chips per unit area also rises sharply.

Thermal performances of cross-flow microchannel heat sinks
Proceeding of Proceedings of CHT-21 ICHMT International Symposium on Advances in Computational Heat Transfer, 2021 A numerical investigation is carried out that show how reasonably good thermal performances can be obtained with cross-flow microchannel heat sinks provided that an unequal number of microchannels is used in the two layers and a non-uniform microchannel ...
