Abstract
This paper considers the issues of heat transfer intensification in the air cooling system of heat-loaded elements of radio-electronic equipment based on split fins. The results of the study of heat transfer in free and forced convection cooling systems for heat-loaded elements of electronic equipment are presented. The thermal efficiency of systems based on smooth and partially split ribs is compared; the efficiency of split ribs is 16-20%. The dependences of thermal resistance on thermal load are determined. The results of a comparison of mathematical and physical modeling are provided. The influence of the method of supplying heat to split ribs is estimated. Optimization of the work area is presented.
