Abstract: Enhancing heat transfer in miniaturized radiators is an important goal for many researchers. In this study, silver nanofluids were employed to improve the transfer of heat in micro-pin fin heat sinks. A Hot Disk 2500 thermal constant analyzer measured the thermal conductivity of the silver nanofluid samples using the transient plane source (TPS) technique. Results showed that the addition of silver nanoparticles to the working fluids improved thermal conductivity, but at high concentrations, the nanoparticles increased viscosity of the base fluids which hindered heat transfer.
