Selection of proper phase-change material (PCM) plays a crucial role in the development of latent heat thermal management module. Very often, selection of improper material leads to early failure of the product which results in huge economic loss. Most of the researchers utilize PCM in a particular application based on their experience and availability. The designer needs to consider all possible alternatives and evaluate in terms of various conflicting criteria or attributes. The optimal selection of PCM for a particular application is a multiattribute decision-making problem. Here, two evaluation techniques such as technique for order of preference by similarity to ideal solution (TOPSIS) and fuzzy TOPSIS are employed to select the optimal PCM for thermal management of electronic components. The analytical hierarchy process technique is utilized to determine the weight of the attributes. The present study considers 30 PCMs and 11 attributes for the selection of best PCM. The results are compared with both the methods and it is observed that RT 44 HC is found to be optimal PCM for thermal management of electronic components. The model is validated and results are found to be in good agreement with the existing experimental results.

“…Ren et al [15] numerically investigated the impacts of the pin-fin configuration, expanded graphite (EG) content, PCM melting temperature, and heating conditions on the thermal performance of the MEPCM-EG composite with pin-fins using the three-dimensional (3D) lattice Boltzmann method. The results showed that a pin-fin array with medium fin number and fin thickness helps balance the increased heat transfer capability and the decreased latent heat of the MEPCM to achieve the optimum thermal performance.…”

In this paper, a numerical method is used to investigate the conjugate heat transfer of a phase change material (PCM) suspension in a circular tube under external cooling convection. The following parameters and ranges were considered: dimensionless tube wall thickness, t w (0–0.5); wall-to-fluid thermal conductivity ratio, k w f * (0.1–10); volumetric fraction of PCM particles, c v (0.1); Biot number, B i o (1); Stefan number, Ste (0.1); and Peclet number, Pe (1000). The results show that the wall thermal conductivity considerably affects the outer/inner wall temperature of the tube, the average temperature of the working fluid, and the volumetric liquid fraction of PCM particles. Thus, wall conduction effects must be properly accounted for to model heat transfer in a PCM suspension in tube flow.

Photovoltaic technology plays a crucial role in harnessing renewable energy. While photovoltaic panels directly convert solar energy into electricity, more than 50% of solar radiation is lost as waste heat, diminishing the overall efficiency of the panels. This study reviews various cooling technologies for photovoltaic systems, focusing on the use of phase change materials for cooling in photovoltaic systems. Phase change materials, known for their high latent heat capacity, are extensively used in thermal energy storage applications. Incorporating phase change materials in photovoltaic systems can increase thermal storage potential by 30–50% compared to conventional systems, leading to a 70% extension in heat storage duration and various levels of enhanced power output. The main purpose of the article is to review the advantages and disadvantages of various technologies, determine the research direction of phase change materials for cooling systems in photovoltaics, and ensure the reliability of this technology.
