| Abstract | In the design process of switch cabinet, the heat dissipation of current-carrying loop is one of the key problems. By introducing the heat conduction differential equation, Navier-Stokes equations and radiation heat transfer equation, the multi-physical field coupled mathematical models are established for researching the heat dissipation problem in the switch cabinet in this paper. The mathematical models and the finite volume method are presented to compute the three-dimensional thermal and fluid fields of KYN28A-12 switch cabinet. And wall function method is used to deal with convection heat transfer boundary conditions. Then the hexahedral finite element mesh method is used in the numerical calculation. The thermal and fluid fields are calculated respectively in two different conditions, natural convection and forced convection. Compared with natural convection, the temperature in the forced convection is obviously lower. The heat dissipation of the current-carrying loop is increased in the situation of forced convection. |

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.
