Abstract

Microchannel heatsink is an advanced technology in the cooling system that gives a superior performance to remove high heat flux generated by a modern electronic device. Many innovations of microchannel design have been dedicated to improve the thermal performance in microchannel heatsink. Besides that, application of nanofluid as a coolant in microchannel heatsink has been attracting a lot of interest among researcher due to the enhancement of thermal conductivity in a nanofluid with a small percentage of the nanoparticle. The enhancement has contributed to heat transfer augmentation in microchannel heatsink. In this paper, a comprehensive review about nanofluid as a coolant regarding its performance based on the concentration and size of nanoparticle in microchannel heatsink was presented and analysed. The discussion of this review focused on the methodology used to analyse the performance of nanofluid in a microchannel, flow condition, channel design and type of nanofluid. Finally, the suggestion of nanofluid selection, nanoparticle concentration, nanoparticle size and flow condition have been pointed out.
