Experimental investigation on heat transfer enhancement in a minichannel using CuO-water nanofluid

In this work, CuO-water nanofluid with an average size of nanoparticles (24?nm) and volume concentrations of 0.1% and 0.5% is used. For the computer microprocessor cooling, an aluminium minichannel of dimension (40???1???3) mm(3) is fabricated instead of an aluminium heat sink and a cooling fan. It is shown that the dispersion of nanoparticles into the distilled water has produced a considerable enhancement of the cooling of the minichannel. Experiments were conducted for Reynolds number ranging from 25 to 800 under a laminar regime. From the experiments, it is found that better heat transfer is achieved when CuO-water nanofluid is used as the working fluid.
