Since they have such high heat transmission properties, nanofluids are becoming increasingly important in thermal applications. The electronics industry uses micro-scale heat transfer devices extensively, which has led to the creation of tiny heat exchangers with high heat transfer coefficients. The use of dispersed nanoparticles in base fluids is a recent invention in the field of nanotechnology that improves the heat transfer coefficient of base fluids. This study provides an overview of the literature on the use of nanofluids to improve convective heat transfer in microchannel heat exchangers and the impact of different thermophysical parameters on heat transfer performance. In this study, theoretical and experimental findings for various geometries and their impacts on the Nusselt number are presented. The findings indicate a remarkable rise in the significance of using nanofluids in microchannels. Effects of using various nanofluids and how they perform in comparison to basic fluids.
