“…Various nanofluids have been compared along with the absorber tube material for finding the material that provided the most efficiency. It was found in a study, [23] that copper gave the maximum outlet temperature compared to steel and aluminum. Nanofluids have also been seen in the evacuated tubes and the entropy generated is analyzed [24].…”

In this paper, discussions have been made about parabolic trough collectors, their various components and modifications implemented in those systems. It has been seen in this study, that the implementation of design modifications to absorbers, the use of various heat transfer fluids, the use of a secondary reflector as well as the use of pin fins enhance the performance of these Collectors. Furthermore, explanations have been done on the various methods and tools such as the Monte Carlo Ray Tracing method implemented while developing these improvements to the existing system. During this study, it has been observed that varieties of twisted tubes have been used which is one such advancement toward a plane tube absorber. It has been observed that the implementation of changes in the receiver tubes can lead to a system having an efficiency of around 75.5% as compared to the systems with simple tubes while modifications to the reflectors enhance the optical efficiency of the collectors by 5%. It has also been observed that the application of Twisted Tubes enhances the performance by 9.2% more than plane tubes. It has also been found that the fluids used in the absorber tubes have been experimented with wherein nanofluids have been utilized thereby resulting in increased performance. It can be concluded that the maximum thermal achieved by the MWCNT nanofluid is 22% higher than the base fluid.

“…The HS was the primary part of the experimental setup made of aluminum. Aluminum material was chosen instead of copper due to its lightweight, threetimes lower density, good thermal conductivity, and corrosion resistance, making it an appropriate choice for thermal inspection [34]. The internal dimension of the heat sink was 101 × 101 × 27 mm 3 with an outer side wall thickness of 7.5 mm.…”

In the modern digital world, electronic devices are being widely employed for various applications where thermal performance represents a significant technical challenge due to continued miniaturization, high heat generated in the system, and non-uniform high-temperature causing failure. Phase change materials (PCMs) owing to the immense heat of fusion are primarily considered for thermal management, but their insulating properties hedge their applications in electronics cooling. Nano-enhanced phase change materials (NePCMs) have the ability to improve the thermal conductivity of PCM, decrease system temperature and escalate the operating time of devices. Accordingly, the current study focused on the experimental investigations for the thermal performance of three heat sinks (HS) with different configurations such as a simple heat sink (SHS), a square pin-fins heat sink (SpfHS), and Cu foam integrated heat sink (CufmHS) with various alumina nanoparticles mass concentrations (0.15, 0.20 and 0.25 wt%) incorporated in PCM (RT-54HC) and at heat flux (0.98–2.94 kW/m2). All HSs reduced the base temperature with the insertion of NePCM compared to the empty SHS. The experimental results identified that the thermal performance of CufmHS was found to be superior in reducing base temperature and enhancing working time at two different setpoint temperatures (SPTs). The maximum drop in base temperature was 36.95%, and a 288% maximum working time enhancement was observed for CufmHS. Therefore, NePCMs are highly recommended for the thermal management of the electronic cooling system.
