Impact of surfactant on Al2O3/water nanofluids stability for cooling the central processing unit of computer

Abstract

In order for a computer to perform well, it is important to keep the central processing unit (CPU) cool, and this can be accomplished by using a liquid coolant. This study was conducted to investigate how effective nanofluids could be as a coolant for a water block used in CPU cooling. The nanofluids used in the experiment contained Al2O3 nanoparticles and SDS surfactant in a mixture in water at volume fractions of 0.5%. They were prepared using an ultrasonic cleaner, and then tested to determine how well they transferred heat and the amount of pump power needed. The findings suggest that nanofluids with higher concentrations have better convection coefficient values and are more efficient at reducing the temperature of the water block, but they require more pumping power. It was concluded that the Al2O3 nanofluid with SDS surfactant could be used as a coolant for CPU cooling because of its effectiveness in lowering the temperature of the water block. The present work results are agreed with data available in the literature.
