NUMERICAL MODELING OF THERMAL MODES OF POWERFUL ELECTRONIC DEVICES UNDER NATURAL CONVECTION CONDITIONS
Abstrakt
The present paper deals with the method and findings of research into thermal modes of powerful electronic devices (semiconductor converters) in which a natural convection of cooling air occurs. The research was performed using the numerical method based on the two-dimensional conjugate model of heat transfer and the applied program package developed by the authors. Math matical statement of the problem includes the set of the Navier−Stokes equations and energy equation. The findings are presented as temperature dependences appropriate for the case considered and as a flow field in the design range.
