“…Table 3 shows the list of nanofluids that had been used in the liquid cooling systems for CPU with heat transfer coefficient analysis. Type of nanofluid had been used is CuO [10,12,15,22], Al2O3 [10,14,21,23,24], TiO2 [9,25], SiO2 [16] , ZnO [10], graphene [13,26], CNT [18] and MWCNT [19]. It is difficult to compare the best nanofluids as there are various concentrations and heat generation is used.…”

“…The convective heat transfer coefficient of nanofluids with a mass fraction of 0.1-0.4% was significantly higher than deionized water, and the convective heat transfer coefficient of Cu-water nanofluids was about 1.1-2 times the heat transfer coefficient of the DI water.

“…From the literature reviews, it is confirmed that a higher concentration of nanofluid has better heat transfer performance. Unfortunately, most of the studies just use a small percentage of nanofluid approximately <5% concentration in the liquid system [10,11,22]. One of the considerations of the selected concentration is the stability of nanofluid.…”

Electronic devices are becoming more efficient while getting a smaller size and compact design thus increase heat generation significantly. High heat generation from high technology electronic devices are needed to be cool down or control its temperature to prevent overheating problems. Due to the high cooling performance of liquid cooling, the electronic cooling system is shifting from an air-cooling system to a liquid cooling system. In the past few decades, numerous methods proposed by researchers for the central process unit (CPU) cooling using the liquid system either active cooling or passive cooling system. Other than physical configuration such as heat sink design, different configurations of working fluids are widely been studied by most of the researchers. Different working fluids have different heat transfer performance. Furthermore, a recent study has come out more interesting finding using nanofluid which can enhance heat transfer performance of liquid cooling. Nanofluid is a working fluid that has nanoparticles disperse in the base fluid which can increase the thermal properties of the based fluid. In this paper, comprehensive literature on the type of working fluid used in the respective system and methods of liquid cooling system for CPU including its cooling performance. Furthermore, this review paper discussed the different configuration of the liquid block and also the working fluid that had been used in the CPU cooling system.

“…Al-Rashed et al [28] conducted a study to evaluate the thermal and entropic properties of a non-Newtonian nanofluid containing CuO particles in the substrate (MCHS). This article discusses the effects of concentration of nanoparticles, the Reynolds number as well as the geometric size intended for MCHS based on the first and second laws of thermodynamics.…”

Transfer of heat and mass and thermodynamic irreversibilities are investigated in a porous, parallel-plate microreactor in which the working fluid is non-Newtonian. The investigated microreactor features thick flat walls with uneven thicknesses, which can be subject to different thermal loads. The dimensionless governing equations of the resultant asymmetric problem are first derived theoretically and then solved numerically by using a finite volume technique. This results in two-dimensional solutions for the velocity, temperature and concentration fields as well as the distributions of Nusselt number and local and total entropy generations. The results clearly demonstrate the significance of the numerical value of the power-law index and departure from Newtonian behavior of the fluid. In particular, it is shown that by increasing the value of power-law index the Nusselt number on the wall decreases. This leads to the intensification of the temperature gradients in the system and therefore magnifies the local and total entropy generations. Also, it is shown that the wall thickness and thermal asymmetry can majorly affect the heat transfer process and thermodynamic irreversibility of the microreactor. It is noted that the current work is the first comprehensive study of heat transfer and entropy generation in porous micro-chemical reactor with non-Newtonian, power-law fluid.

“…Recently, the use of nanofluids, which is in fact a stable suspension of nanofibers and solid nanoparticles, has been proposed as a new strategy in heat transfer operations. The preparation of nanofluids by the addition of nanoparticles to the base fluid should not be considered as a simple solid–liquid mixture 10,15‐18 . Because nanofluid preparation requires special conditions, some of these special conditions include suspension uniformity, suspension stability, and low particle mass, and no change in fluid chemical nature 19‐23 .…”

The use of nanofluids and surface enhancers today are among the new technologies used to increase heat transfer. In this study, heat transfer phenomena in heat exchanger were investigated using Al2O3 nanoparticles and modified spiral band as flow turbulator. Results are verified with well‐known correlations. The results show that the tube with cross‐hollow twisted tape inserts has the best exergetic performance for different hollow widths of the tape. Clearance, which is defined as the width between the tube and twisted tape, also affects the heat transfer performance. The smaller the clearance, the better is the exergetic performance. The tube can achieve the best exergetic performance when the number of unilateral twisted tapes is four. The results showed that increasing nanofluid concentration improves exergetic performance.
