# 电子器件散热器综合性能评估Comprehensive Performance Evaluation of Electronic Device Radiator

Abstract: In this paper, the comprehensive performance of fin radiator is studied by the theory of fuzzy ma-thematics. The model is built with the help of MATLAB fuzzy toolbox, which has the following fea-tures: when the heat transfer coefficient, thermal resistance and pressure drop of the radiator are known, the comprehensive performance level of it can be obtained. The results elucidate that the discrete performance is better than that of the integrated and in this example, the best overall performance of the radiator is four of the subsection numbers. This research has certain directive significance to the comprehensive performance evaluation and selection of radiator.
