Abstract

The work deals with the simulation of naturely and forced cooled switchboard in the steady operating state. There is described here the procedure of measuring of the warming with measuring instruments. Further thermal properties of materials, thermal states including the methods of heat transfer. As the next, there is a description of CAD program and of the set of ANSYS programs, which use the method of finite elements. The part of this work is conceiving of a numerice model based on the actual draft with the description of creation the simulation of the static thermal analysis in particular steps. Results are shown for both modeled types focused on the temperatur distribution view of heat transfer coefficient and on airflow issues in the switchboard and in its neigborhood.
