| Summary: | 碩士 === 國立中央大學 === 光電科學與工程學系 === 103 === In this research, shape factor is regarded as basis and finite element analysis (FEA) software is used to build the three-dimensional axisymmetric model, and then find the figure related to shape factor and geometric shape. After fitting the curve of figure, the rapid estimation of thermal resistance method is built. The rapid estimation of thermal resistance method can apply to not only axisymmetric structures but also composite structures, square structures and asymmetric structures. Finally, the thermal resistance of an actual LED thermal module will be optimized by simulated annealing. The rapid estimation of thermal resistance method cam not only estimate the thermal resistance of the sample effectively and rapidly but also reduce the time, manpower and money during the period of design.
