Effective thermal management is a key for the continuous development of electronics, which are characteristics
of modern life. It has a great effect on the lifetime, durability and reliability of these systems. A liquid-cooled
microchannel heat sink is a compacted cooling part that used to provide better heat dissipation rates and low
temperatures in electronic components. Nanofluids have been introduced as effective coolants to be employed in
this type of heat sink to increase the heat dissipation rate. However, a comparative assessment of the thermal
performance between commonly used nanofluids and water as coolants for microchannel heat sinks is still
lacking. For this purpose, a computational fluid dynamics (CFD), non-isothermal, three-dimensional detailed
model has been developed to simulate and analyze the fluid flow and heat transfer physiognomies. The results
show that examining performance parameters as functions of Reynolds number is misleading since the ther-
mophysical properties are different among each coolant, and that employing nanofluids in a microchannel heat
sink is impractical as water is cheaper and safer.
