Summary: This paper introduces a novel PCM-to-air and liquid heat exchanger for thermal energy storage, which can provide a hybrid heat source and improve thermal system performance. Numerical simulations are used to analyze the heat transfer characteristics and phase change process, and the effect of airflow variation on the thermal response is studied. Experimental results demonstrate that the PCM can store and release excess heat during charging and discharging processes, providing extra heating time for the airside.

Summary: This study reviewed literature on cascaded latent heat storage (CLHS) technology to analyze the research progress, challenges, and future directions. The results showed that the thermal advantages of CLHS can be further enhanced by optimizing the structure of the heat storage unit and the physical properties of the phase change material (PCM). The main challenges of this technology are the selection, development, and distribution of PCMs. Future research should focus on developing more accurate intelligent optimization algorithms and dynamic models, as well as studying practical applications in low-temperature thermal energy storage and cold storage.

Summary: In this study, beeswax was used as a phase change material to store heat, and its thermal conductivity and melting point were improved by adding nanoparticles and other phase change materials. FeO nanoparticles were found to give the best result for enhancing thermal conductivity, and the addition of coconut oil helped lower the melting point of the beeswax. The composite of beeswax and coconut oil with FeO nanoparticles showed the best performance in terms of charging time reduction.

Summary: Phase change materials (PCMs) have garnered increased interest for their ability to absorb and store large amounts of thermal energy with minimal temperature variations. Current studies primarily focus on enhancing thermal conductivity and reducing charging/discharging times, with limited exploration into increasing latent heat and stability. Recommendations for further research include better understanding stability, identifying factors with greatest impact, and determining PCM combinations for significant increases in latent heat.

Summary: This paper reviews the application of nano-enhanced PCM in LHTES systems, focusing on the impact of different enhancement measures on improving the thermal conductivity of PCM and the research on related materials. Studies have shown that NPs can effectively enhance the performance of PCM, but research on medium and high temperatures still remains relatively scarce and should be further strengthened in future studies.

Summary: This study proposes a variable fin thickness design for the vertical plate-fin heat sink (PFHS) to address thermal issues. Simulations using COMSOL Multiphysics show that the influence of the fin convergence angle increases with the number of fins in the PFHS. The maximum reduction in thermal resistance is 45.5% for the highest density of fin numbers. The study also explores using phase change materials (PCMs) and air cooling for thermal management, with results indicating that using PCM can decrease the critical temperature of PFHS by up to 8%.
