摘　　要：通过Ansys Workbench对一体集成小型化YIG调谐带阻滤波器组件进行热仿真分析,得出在自然散热条件下,组件中部分发热元件的温度为170℃以上,超过了元件允许工作温度125℃,组件可靠性无法得到保证。为此,在组件底部增加散热板以增大散热面积,改善散热条件。仿真结果表明,各发热部件的温度大幅下降,组件中发热元件的最高温度是PTC热敏电阻,为118℃,线圈、控制驱动、大功率三极管温度分别为99℃、104℃、116℃,均低于元件允许工作温度,满足设计要求,保证组件全温度环境下可靠工作。在一体集成小型化组件的设计中,合适的元器件布局和散热方式是组件的可靠性的重要设计因素,且利用热仿真分析,可以降低组件的实物试制成本和验证成本,缩短研发周期,提高研发效率。The thermal simulation analysis of the integrated miniaturized YIG-tuned band rejection fliter module is proceeded by Ansys Workbench.It shows that the temperature of some heating elements in the module is above 170℃under the natural heat dissipation condition,exceeding the allowable working temperature of the components by 125℃,so the reliability of the module cannot be guaranteed.Therefore,a heat dissipation plate is added to the bottom of the assembly to increase the heat dissipation area and improve the heat dissipation conditions.The simulation results show that the temperature of each heating component drops greatly after adding the heat dissipation plate,and the highest temperature(118℃)of the heating component is the PTC in the module.The temperature of the coil,control circuit and high power triode is 99℃,104℃,and 116℃respectively,lower than the allowable working temperature of the components,ensuring the reliable operation of the assembly in full temperature environment.Proper component layout and heat dissipation are important design factors of component reliability in the design of integrated miniaturized module,and the thermal simulation analysis can reduce the cost of trial production and verification of modules,shorten the research cycle and efficiency.
