Summary: The enhanced cooling performance of a phase change material (PCM)-integrated fin-type heat sink is reported in high power electronics. By embedding a phase change composite into the base plate of the heat sink, the thermal capacitive effects and excellent heat spreading characteristics of PCM are effectively utilized for thermal management. Experimental and numerical investigations show that the PCM-integrated fin-type heat sink can effectively delay the temperature rise of hot spots, demonstrating its potential for use in convection-limited cooling environments.

Summary: In this study, a novel active-passive cooling heat sink thermal management system based on the composite of phase change materials and metal foam is designed to improve the thermal performance of the active antenna unit device for the fifth-generation mobile communication technology base station. The numerical investigation considers the effect of transient heat flux and examines the influences of phase change temperatures, porosity of the metal foam, and pore density of the metal foam on the heat sink's thermal performance. Results show that the novel active-cooling heat sink thermal management system outperforms traditional active cooling heat sinks without phase change materials and metal foam, with a maximum temperature decrease of 10 K and an enhanced temperature control efficiency of up to 19%.

Summary: A novel PCM-grouted borehole heat exchanger (BHE) is proposed for all-season operation using a single shape-stabilized PCM (SSPCM) with phase change hysteresis (PCH). A heat transfer model considering PCH is established to evaluate the thermal performance of the BHE. Results show that octadecane SSPCM with PCH exhibits the best comprehensive performance, with energy storage rates of 68.9 W/m in heating and 75.9 W/m in cooling, higher than conventional BHE with backfill material.

Summary: Space heating and cooling are major energy consumers in buildings, with reliance on fossil fuels contributing to greenhouse gas emissions and climate change. Ground-source heat pump systems are effective but costly, leading to declining efficiencies over time, especially in extreme climates. Thermal caissons offer a solution to reduce costs and maintain efficiency, improving performance and stability.

Summary: Phase change materials (PCM) are used to buffer temperature swings in electronic devices, improving reliability and reducing volume and weight of thermal management systems. However, their effectiveness is limited to a narrow range of operating conditions, which presents challenges in designing PCM-integrated thermal management solutions that can operate over a broader range. This paper explores the impact of diverse operating conditions on the cooling performance of PCM-integrated power devices.

Summary: The experimental study on PCM-based finned heat sinks for thermal management of electronic devices shows that more fins lead to lower operating temperature, while higher input heat flux results in higher operating temperature and shorter duration of low operating temperature. Increasing PCM volumetric fraction enhances thermal storage capacity and reduces operating temperature.

Summary: In this work, a heat sink combining the confined jet impingement with metallic phase change material (PCM) is proposed for the thermal management of millisecond-pulsed heat sources. The heat transfer characteristics of the heat sink and the temperature responses under millisecond heat pulses are analyzed. Results show that the jet impingement with specific parameters can achieve effective cooling, and an appropriate PCM thickness is required for stable phase change cycling.

Summary: This study investigated the cooling effect of micro-encapsulated phase change material slurry (MPCS) in double-layered minichannel heat sink (DL-MCHS) for concentrator photovoltaic (CPV) cells. The results showed that the lowest top temperature of the CPV cell decreased by 0.56 degrees C with the counter arrangement of the DL-MCHS. The Delta P and h were significantly influenced by Reynolds number, concentration, and wavelength. After optimization, the highest performance evaluation criteria (PEC) of MPCS in the wavy minichannel was achieved at 1.60.

Summary: The study investigates a hybrid thermal management technology using air cooling and hybrid composite phase change material (HcPCM) filled finned heat sink to cool lower to medium heat flux dissipating electronic devices. Numerical simulations are conducted to study the heat transfer effects of three types of finned heat sink: air-cooled, HcPCM-cooled, and hybrid (air-HcPCM) cooled. The results show that forced convection heat transfer improves the cooling performance compared to natural convection. The addition of nanoparticles enhances thermal efficiency and uniform melting of the PCM. The recommended concentration of 2% GO+MWCNTs nanoparticles achieves uniform melting inside the finned heat sink.
