Summary: Managing temperature of lithium-ion cells in battery packs is crucial for their safe operation. Traditional cell datasheets lack sufficient thermal information to determine thermal management capability. This study introduces the Cell Cooling Coefficient (CCC) as a metric for defining thermal dissipation from a cell when rejecting its own heat. The study successfully defines and measures the CCC for cylindrical cells under base cooling, and evaluates the CCCBase of LG M50T (21700) and Samsung 30Q (18650).

Summary: This paper examines the cooling of an 18,650 cylindrical lithium-ion battery by placing fins on its surface and immersing it in phase change material. Sensitivity analysis of the fin dimensions is performed and an optimal model for heat management system is provided. Results show that using phase change material and fins can reduce the battery's surface temperature. Sensitivity analysis reveals that fin length has the greatest effect on temperature reduction. Increasing fin size and distance between fins enhances the amount of phase change material. Increasing fin height lowers the battery temperature, while increasing fin width initially decreases and then increases temperature.

Summary: This study presents an immersion cooling system that uses water as the cooling medium and introduces a special seal structure to prevent water contact with the battery. The results show that even at high discharge rates, a small water flow rate can ensure the maximum temperature of the battery pack stays below 50 degrees Celsius. However, reducing the temperature difference of the battery pack requires a larger water flow rate and the addition of a buffer structure.

Summary: In the past decade, there has been a growing interest in studying energy systems for the combined management of power vectors. Most of the published works focus on finding the optimal design and operations of Multi Energy Systems (MES). However, for newcomers to this field, understanding how to achieve the desired optimization details while controlling computational expenses can be challenging and time-consuming. This paper presents a novel approach to analyzing the existing literature on MES, with the aim of guiding practical development of MES optimization. Through the discussion of six case studies, the authors provide a mathematical formulation as a reference for building the model and emphasize the impact of different aspects on the problem nature and solver selection. In addition, the paper also discusses the different approaches used in the literature for incorporating thermal networks and storage in the optimization of multi-energy systems.

Summary: This paper investigates the heat transfer mechanism and factors influencing thermal radiation in the process of supercritical water gasification (SCWG) of coal, and proposes a comprehensive numerical model to simulate the process. Experimental validation results show that thermal radiation accounts for a significant proportion of the total heat exchange in the reactor and a large amount of radiant energy exists in the important spectral range of supercritical water. Enhancing radiative heat transfer can effectively increase the temperature of the reaction medium and the gasification rate.

Summary: Pulsating Heat Pipes (PHP) are passive two-phase heat transfer devices with a simple structure and high heat transfer capabilities. The actual unpredictability of their dynamic behavior during startup and thermal crisis hinders their large-scale application. An experimental apparatus is designed to investigate these phenomena systematically. The results show that increasing the number of evaporator sections and condenser temperature improves the performance of PHP. The condenser temperature also affects the initial liquid phase distribution and startup time.
