“…Experimental analysis of the use of offset strip miniature heat sinks prepared in different strip shapes and thicknesses with the Al 2 O 3 -water nanofluid was conducted by Aliabadi et al [40]. From the results, better cooling performance was obtained with the use of miniature heat sinks with the nanofluid than with the use of the base fluid.…”

With the developing technology, the dimensions of electronic systems are becoming smaller, and their performance and the amount of energy they need increases. This situation causes the electronic components to heat up more and the existing cooling systems to become inadequate. In this study, instead of the fins used in existing systems, 10 PPI and 40 PPI PHS were placed inside a water block, and the Al2O3-H2O nanofluid at a mass fraction of 0.1% was used as the cooling fluid. Experiments were carried out under constant heat flux of 454.54 W/m2 and 1818.18 W/m2, with volumetric flow rates varying between 100 mL/min and 800 mL/min. The heat transfer results were compared with the results obtained from the base fluid and the empty surface. The results showed that the nanofluid reduced the surface temperatures compared to the base fluid. Especially when PHSs were used together with the nanofluid, a significant increase in heat transfer occurred compared to the empty surface. The highest heat transfer was observed when both the nanofluid and 40 PPI PHS were used together. In addition, the highest thermal performance value was determined as 1.25 times compared to the empty surface when the nanofluid and 10 PPI PHS were used together.

“…Afzal et al 31 elaborated the effects of coolant flow rate on Nu, pumping power, and pressure drop of a heat sink with circular channels. Aliabadi et al 32 also revealed the effects of design parameters on hydrodynamic and thermal aspects of an offset‐strip pin minichannel heat sink by employing Al 2 O 3 –water nanofluid. Mitigation of the strip thickness displayed enhancement in coefficient of heat transfer.…”
