Abstract: The relentless advancement of electronic devices has led to increased power densities, resulting in thermal challenges that threaten device reliability. This study aims to address this issue through the development of innovative heterogeneous materials for cooling electronic components. We focus on phase change materials (PCMs) impregnated within architected porous structures fabricated using additive manufacturing technology and 3D printing techniques. The objective is to leverage numerical simulations and additive manufacturing technology to select suitable materials and optimize heat dissipation within these structures. A comprehensive literature review of existing thermal management systems (TMS) for electronic devices, including mobile phones, laptops, and data centres, is presented. This review establishes a foundation for understanding the significance of TMS and introduces the benefits of employing PCMs in electronic devices. To assess the impact of the structure materials, we have run numerical simulations involving stainless steel, silver, Inconel, aluminium, copper, titanium, and steel architected porous structures impregnated with palmitic acid as the PCM. The results demonstrate the superior heat dissipation of silver, copper, and aluminium porous structures, attributed to their higher thermal diffusivities. Other simulations explore PCMs with higher melting temperatures and latent heat capacities, considering specific application parameters like mobile phones and laptops. By integrating three organic PCMs (Myristic acid, Palmitic acid, and Stearic acid) within architected matrices, it offers a promising solution in the choice of PCMs to the challenges posed by high power densities in electronics. This approach deepens our understanding of the melting process and allows the optimization of heat transfer within architected structures.
