Parametric Optimization and Multi-Analysis of Skeletal Fin Heat exchanger with Integrated PCM: Advancing Thermal management for Electronics and Telecommunications Systems

This study investigates dependent factors such as parameters of geometry which effect of design factors on temperature on the top of fins, temperature variation, the energy storage rate, thermal energy, the surface Nusselt number and the surface Stanton Number. The authors give insights into the link between design factors and thermal performance, allowing for a thorough computational fluid dynamic study of the data. The authors have examined relationship between factors of design and thermal performance indicators with integrated phase change materials, considering material properties, and design parameters. The adding skeletal fin step by step is the most significant and contributes to temperature variation, output temperature, thermal energy storage rate, density of the thermal energy storage, thermal energy storage, surface Nusselt number, and surface Stanton number. The relationship and regression model between temperature variation and temperature output on top has 99% R ² value; and between energy storage rate and density of thermal energy storage, and temperature variation has the relationship with 78%R ² value. However, the analyses show the reducing of the errors between simplified and detailed analysis of variance equal to 46% for temperature on the top of skeletal fins, 46.5% for temperature variation, 27% for energy storage rate, 0% for density of thermal energy and thermal energy storage, 6% for surface Nusselt number, and surface Stanton number. Finally, a parametric simulation is carried out to investigate the percentage of contribution and impact of significant performance parameters on the skeletal heat exchanger characteristics of the respective skeletal heat exchanger type.
