摘要

Improving energy efficiency through the integration of micro-channel designs with thermal storage systems offers a promising approach for advanced heat transfer applications. Despite their advantages, micro-channels are often challenged by fouling and clogging, which can reduce thermal performance over time. This review highlights strategies to enhance system efficiency by combining optimized micro-channel structures with advanced thermal storage materials. Recent progress in materials and fabrication techniques such as the use of metals, polymers, ceramics, and precision methods like photolithography and soft lithography has enabled more durable and effective designs. Integrating micro-channels with phase change materials (PCMs) and sensible heat storage media improves both charging and discharging processes, leading to higher heat transfer rates and reduced energy loss. Reported studies show that such integrated systems can enhance heat transfer rates by 25–60% and reduce energy losses by up to 35% compared to conventional micro-channel configurations. This synergistic approach shows strong potential for creating compact, efficient, and sustainable thermal systems that support the global shift towards cleaner and more energy-resilient technologies.
