| Abstract | Ever increasing device density in electronic chips is beneficial for enhancing their computing efficiency. However, it also introduces severe challenges with respect to cooling solution which are indispensible for ensuring a reliable chip operation. Such steady miniaturization will soon render the traditional air cooling strategies futile and make the switching to liquid cooling inevitable. Superior thermal properties and ubiquitous availability make water the most suitable candidate as coolant. Building up on the reported studies in the literature, which have already established the feasibility of water as coolant, here we show that the superior thermal properties of water make it possible to cool electronic chips and data centers using hot water with inlet temperature up to 60°C. The concept is demonstrated through measurements on a copper made scalable manifold microchannel heat sink and a hot water cooled data center prototype. The high exergetic efficiency achieved using hot water cooling should make it possible to reuse the heat otherwise discarded in data centers and therefore improve the overall system efficiency and lower the carbon foot print of the data centers. Finally, the encouraging results are used to model water cooling of 3D chip stacks using an interlayer integrated cooling approach. The model results are compared with measurements on a model simulator and good agreement is found, which lays the ground work for realizing a model based optimization of integrated cooling structures for 3D chip stacks. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
