Summary
With the increase of the computing power for data centers, the integration of the transistors per unit area in electronic chips improves, which leads to a sharp increase in transient heat load and local hot spots. The non-uniform load distribution on the chip and the local hot spots in the thermal environment are the key issues of the data centers. The main theme of this Special Issue covers comprehensive and up-to-date knowledge in the field of energy efficiency management, room-level cooling, server/cabinet-level cooling, chip-level cooling, and thermal-humidity environment in data centers. Through a collection of scientific articles and reviews, this Special Issue aims to shed light on the latest achievements in the field of broadly understood thermal management systems in data centers, and modern technological solutions, including intelligence algorithm.
