About this Research Topic
Energy use is a central issue for data centers. Power draw ranges from a few kW for a rack of servers in a closet to several tens of MW for large facilities. To save electrical energy in data centers, it is of great significance to develop efficient cooling technologies. Among the available cooling methods, the forced convection, especially the vapor-liquid phase change (evaporation, boiling, and condensation) in channels/grooves of small dimension, is emerged as a powerful and attractive candidate.
Although several experimental and numerical works have been focused on heat transfer related to the data centers, the theories and methods for thermal management of data centers are still required to be further developed to improve the energy efficiency for data centers. Besides, it is still unclear how heat transfer technology affects power usage effectiveness in data centers.
This Research Topic aims to highlight some theories and techniques to meet the emerging challenges of thermal management in data centers, with a special emphasis on microscale heat transfer for efficient cooling. We invite Original Research, Review, Brief Research Report, Mini Review, and Perspective focused on all aspects of heat transfer in data centers, including liquid cooling, heat pipe, boiling cooling, evaporation cooling, heat storage, solid-liquid phase change, etc.
Keywords: microscale, heat transfer, data centers, boiling, evaporation, heat storage
