A new approach using un-encapsulated discrete PCM chunks to augment the applicability of solid gallium as phase change material in thermal management applications

A review of metallic materials for latent heat thermal energy storage: Thermophysical properties, applications, and challenges

“…Low melting point alloys (also called liquid metals) have been investigated for various potentials applications as thermal management in electronic devices [70,[192][193][194][195][196] , management thermal shock in electronics [168], thermal energy storage [192,197], composite PCMs for solar heat and industrial waste heat recovery application [198], coolant [170,[199][200][201], thermoelectric generation [202], soft multifunctional composites for wearable electronics [203]. In this range of temperatures, there are gallium and Ga-based alloys; their investigation indicates that the purity level of the alloys has a significant impact on the thermophysical properties [204].…”

Sustainable Thermal Regulation of Electronics via Mitigated Supercooling of Porous Gallium‐Based Phase Change Materials

“…In contrast, metallic PCMs provide higher thermal conductivity with less performance degradation compared to that of organics, making them a promising candidate for effective thermal buffer. Several studies have investigated liquid metal (LM) PCMs as heat sink, [ 9 , 10 , 11 , 12 ] in which further extended protection time was attained compared to that of organics, presenting an improved thermal response. Although such LM PCMs provide superior thermal performance, there are still challenges to applying them into electronic packages due to their severe supercooling behavior.…”

Study of Natural Convection Melting of Phase Change Material inside a Rectangular Cavity with Non-Uniformly Heated Wall

“…There are several types of PCM including paraffin, salt hydrates, alloys, fatty acids, and their combinations [8][9], among different types of PCMs, Gallium has been broadly employed for thermal energy storage applications, because of its excellent thermal properties that include low melting point, high thermal conductivity, large specific heat per unit volume, and relatively small volume change. Al Omari et al [10] performed a benchmark experimental study to establish the importance of gallium in thermal management applications. They used gallium as a heat sink and integrated it with other un-encapsulated PCM material for dumping a part of the heat.…”
