Summary: This study assesses the effectiveness of straight channel heat sinks as a thermal solution for high heat generating electronics components and investigates the impact of applying a hydrophobic coating on their performance. The results show that the Nusselt number increases with higher Reynolds numbers and heating powers, indicating improved heat transfer efficiency. However, the hydrophobic coating on the heat sink surface leads to a reduction in the Nusselt number due to the formation and retention of bubbles, hindering heat transfer. Moreover, the pressure drop is influenced by Reynolds number and the presence of bubbles, with gravity playing a role in reducing pressure drop in certain orientations. A hydrophobic coating shows a small decrease in pressure drop, but bubble formation limits its effectiveness to some extent.

Summary: This article presents a new power diode DBW3-3500 encapsulated in a novel press-pack package with a microchannel cooling system. Field tests comparing conventional diodes with single and double-sided water heat sinks and the new diodes with an embedded cooler were conducted and discussed. The measurements showed that even with single-side cooling, the new package reduced the junction temperature by about 40 degrees Celsius compared to conventional liquid cold plates, resulting in improved electrical parameters. The predicted rated forward current reaches 5000 A. Furthermore, the novel solution also offers a reduction in weight and dimensions of the whole system.

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.
