摘　　要：本文运用模糊数学理论对翅片散热器的综合性能进行了探讨研究,使用MATLAB模糊工具箱对系统建立模型,模型实现当给出散热器的换热系数、热阻和压降值时,可以具体得到散热器的综合性能等级。结合具体实例,最后评判得出:分段翅片散热器的综合性能均优于平直翅片散热器的综合性能,本例中分段数为4的散热器综合性能最好。本研究对散热器综合性能的评判及选型具有一定的指导意义。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.
