A review of enhanced heat transfer of single/multiple fluids in microchannel heat sinks
The present study presents the recent research progress on enhanced heat transfer in microchan-nel heat sinks for cooling media.It describes the mechanisms behind enhanced heat transfer using nanofluids,liquid metals,and latent heat functional fluids.Furthermore,it explores various factors that af-fect the heat transfer performance of nanofluids,such as nanoparticle types,volume fractions,and tempera-tures.Additionally,it discusses methods to increase the heat transfer coefficient of liquid metals and analy-zes how wall materials of microcapsules,phase-change materials,and mass fractions of microcapsules in-fluence the heat capacity of latent heat functional fluids.Moreover,this study highlights the limitations of these three cooling media and proposes corresponding improvement measures.These findings provide valu-able guidance for selecting appropriate cooling media in high heat flux equipment.
