Optimization of the Heat Sink for the Power Component by Taguchi Method

Abstract:

With the development of manufacture technology, it is a critical problem for the reliability of avionic devices that components have to operate at high heat flux. And the package of components cannot meet the requirements of the heat dissipation. Therefore, it is essential to add heat sink on the top of power components. This paper presents the use of Taguchi method in optimizing the heat sink. The heat sink is designed to balance the weight and the temperate distribution of the component. At first, several parameters of the heat sink, including the base width, the base length, the fin height, the fin number, are chosen to be controllable factors. The machining errors are the uncontrollable factors. Then, four orthogonal arrays are used to lead the design of experiments (DOE). Finite-volume method (FVM) is used to calculate the case temperature of the component. Basing on the results generated by the Taguchi DOE method, the optimal design of heat sink can be chosen. Additionally, the heat sink can be optimized, while the reliability of component and device can be improved by using this method.
