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.

“…Nanofluids have been proven that they have high thermal conductivity because of the excellent thermophysical properties and the intense Brownian motion between nanoparticles; nanofluids have been widely applied in a lot of fields, such as impinging jet cooling, solar thermal conversion, CPU cooling, microchannel cooling, boiling heat transfer, and phase‐changed material (PCM) . Moreover, the rheological properties of nanofluids have been studied, such as rheological behavior and viscosity …”

Convective heat transfer and resistance coefficient of nanofluids upward flowing through helical tubes are experimentally researched in this paper.The effects of three factors (thread pitches [s = 10, 12.5, and 15 cm], inclination angles [β = 0°, 45°, and 90°], and nanoparticle mass fractions [ω = 0.0, 0.1, 0.3, and 0.5 wt.%]) on the heat transfer and flow characteristics are discussed. A thermal efficiency evaluation plot is applied to evaluate the thermo-hydraulic performance of nanofluids. Results show that Nusselt number and resistance coefficient increase with the increasing nanoparticle mass fraction and the decreasing thread pitches. It is also found that helical tube with inclination angle β = 45°shows the best heat transfer performance and that with inclination angle β = 90°shows the worst heat transfer performance. In addition, it is found from the thermal efficiency evaluation plot that the experimental data almost locate in Regions I and II and nanofluids in helical tubes can improve the heat transfer under the same pressure drop. The helical tube with s = 10 cm and β = 45°at the range of Reynolds number (Re > 8,000) shows the largest thermal efficiency.

An experimental system is established to investigate the thermo-hydraulic performance of Fe3O4-water nanofluids in a corrugated tube under various magnetic fields. The influences of magnetic induction intensities (B=0 G, 100 G, 200 G, 300 G), nanoparticle mass fractions (ω=0.0%, 0.1%, 0.3%, 0.5%), electromagnet arrangement modes (one-side electromagnet and two-side staggered electromagnet), kinds of tubes (smooth tube and corrugated tube), Reynolds numbers (Re=800-12000) on flow and heat transfer characteristics are discussed. It is obtained that the augmentation of heat transfer is more sensitive to high nanoparticle mass fraction, high magnetic induction intensity, two-side staggered electromagnet and corrugated tube. A Comprehensive evaluation index is applied to estimate the thermo-hydraulic performance. It can be discovered that the comprehensive evaluation index increases with the increasing Reynolds number at first and then decreases, and the rough surface of corrugated tube delays the appearance of critical Reynolds number.
