| Abstract | Novel thermal management approaches are desired due to the ever-increasing power densities in high-performance microelectronics. The rising power density along with the shrinking real estate in these devices results in a substantial increase in device temperature beyond the typical operating temperatures required for a reliable performance. For the typical silicon based technology, efficient thermal management schemes with high heat transfer coefficients such that heat fluxes in excess of ≈ 100 W / $cm^{2}$ can be dissipated without severely exceeding normal operating temperatures of ≈ 80°C are desired. State-of-the-art single phase cooling technologies that rely on sensible heat are bulky and insufficient under these conditions. As a result, liquid-vapor phase change based novel thermal management solutions which utilize latent heat of vaporization of a fluid for high heat transfer with little temperature increase are needed. In this work, we present a multiphase thermal management scheme where we use arrays of cylindrical micropillars of silicon for thin-film evaporation. The microstructures maintain a continuous liquid supply via capillary pressure while controlling the liquid film thickness and the associated thermal resistance. A variety of silicon samples with various wick geometries were fabricated using standard contact photolithography and deep reactive ion etching. Effects of micropillar diameter, pitch, height and the array length on the maximum heat dissipation capability before dry-out were investigated. An analytical model was developed to predict the experimentally observed values of the evaporative heat flux. While the parametric effects of micropillar geometry were qualitatively captured by the model predictions, quantitative predictions could not be achieved due to the limitations in the experimental setup. These preliminary results suggest the potential of thin-film evaporation on microstructured surfaces for advanced thermal management applications. |

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.
