Published: Feb. 4, 2025

Excessive temperatures can significantly impair the service life and performance of electronic devices, making cooling such devices an increasingly critical issue. This Communication introduces for first time a three-dimensional hydrogel designed effective thermal management. The heat from gateway equipment is absorbed through desorption water molecules within composite hygroscopic material (SHM) encapsulated in gel, leading to remarkable effect. Additionally, material's spontaneous adsorption capability enables self-recovery. Under conditions 80% relative humidity at voltage 5.5 V, 0.35 g (with 5% content) has demonstrated significant effect, achieving temperature reduction up 11.5 °C. represents substantial advancement compared traditional phase change materials (PCM). approach holds broad application prospects future.

Advancements in Phase Change Materials: Stabilization Techniques and Applications

Prabha Materials Science Letters, Journal Year: 2024, Volume and Issue: 3(2), P. 254 - 267

Published: Aug. 14, 2024

Phase Change Materials (PCMs) are innovative materials that absorb and release thermal energy during phase transitions, making them ideal for storage applications. This paper provides a comprehensive overview of PCMs, focusing on their functioning mechanisms, classifications, shape stabilization methods. PCMs operate by storing latent heat melting releasing it upon solidification, thereby maintaining stable temperature changes. They classified into three main categories: organic, inorganic, eutectic. Organic such as paraffins fatty acids, offer high but suffer from low conductivity. Inorganic including salt hydrates metals, provide better conductivity face challenges like supercooling corrosiveness. Eutectic which mixtures compounds, customizable points enhanced properties. To address leakage improve conductivity, methods employed, encapsulation, porous matrix, polymer hybridized stabilization. These techniques enhance the structural integrity performance more suitable practical The highlights potential to efficiency outlines future research directions optimizing in various industries.

Phase-change materials (PCMs) are widely used in the thermal management of electronic devices by effectively lowering hot end temperature and increasing energy conversion efficiency. In this article, numerical studies were performed to understand how instability during periodic utilization affects heat-dissipation effectiveness a phase-change material heat sink embedded an device. Firstly, three amplitudes 10 °C, 15 20 °C for fixed periods time, namely, min, 40 respectively, investigate specific effect amplitude on PCM melting rate. Next, was fixed, impact period performance evaluated. The results indicate that under min time period, averaged rate PCMs with reaches highest at 19 which saves 14 8 compared constant input same At has 6 11 saving dissipation 3 respectively. Overall, it observed identical conditions, peak remains consistent, longer resulting promotion melting. On other hand, similar larger values result faster rates. This is attributed fact increases flux output extending rise, while adjusting temperature.
