| Abstract | Under-hood packaging in hybrid vehicles is highly constrained due to smaller vehicle size and additional electric drive components. Moreover, the increased electrification of hybrid vehicles has resulted in a need for greater electrical power handling capability. These two factors have led to larger power densities (in excess of 200 $W/cm^{2})$ and related thermal management challenges for future hybrid vehicle electronics. In this paper, the design of a compact multi-device single-phase microchannel cold plate for hybrid vehicle electronics applications is explained. The cold plate design utilizes numerous local multi-pass branching microchannel systems arranged in parallel and then connected in series with optimized global inlet and outlet manifolds for efficient coolant flow distribution and device temperature control. Experimental heat transfer and pressure drop results using a 50/50 ethylene-glycol/water coolant are reported as part of this study, where the average cold plate thermal resistance achieved is 0.112 K/W with 9.03 kPa pressure drop at a coolant volumetric flow rate of 2.5 1/min. |

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.
