Abstract
ABSTRACT Heat pipes and vapor chambers have been widely utilized for the thermal management of electronic devices due to their effective heat transport, passive cooling operation, and high reliability. In these devices, a wick structure transports a working fluid from the heat sink to the heat source via capillary action in the wick structure. This paper provides a broad overview of the latest studies on the development of Micro-/Nanostructured wicks for passive cooling systems. Micro/nanopillar-based wick structures provide a high capillary pressure, a large permeability, and larger areas for evaporation, resulting in a significantly higher heat removal capability and dryout heat flux. A special emphasis is placed on the various types and geometries of wick structures and their performance. Additionally, limitations and recommendations for future investigations are discussed.
期刊介绍：
Nanoscale and Microscale Thermophysical Engineering is a journal covering the basic science and engineering of nanoscale and microscale energy and mass transport, conversion, and storage processes. In addition, the journal addresses the uses of these principles for device and system applications in the fields of energy, environment, information, medicine, and transportation.
The journal publishes both original research articles and reviews of historical accounts, latest progresses, and future directions in this rapidly advancing field. Papers deal with such topics as:
transport and interactions of electrons, phonons, photons, and spins in solids,
interfacial energy transport and phase change processes,
microscale and nanoscale fluid and mass transport and chemical reaction,
molecular-level energy transport, storage, conversion, reaction, and phase transition,
near field thermal radiation and plasmonic effects,
ultrafast and high spatial resolution measurements,
multi length and time scale modeling and computations,
processing of nanostructured materials, including composites,
micro and nanoscale manufacturing,
energy conversion and storage devices and systems,
thermal management devices and systems,
microfluidic and nanofluidic devices and systems,
