【摘要】 利用ANSYS热仿真软件对毫米波行波管输出段的散热情况进行仿真,通过对PPM系统的极靴厚度,散热片长度与导热硅胶,底座高度进行分析,研究各种因素对输出段管体温度的影响。仿真结果表明,增加极靴厚度,使用高热导率的导热硅胶,使用较长的散热片与较高的底座,并且散热片与底座紧密接触,都有利于管体温度的降低,增加输出段的散热,减少高温度对毫米波行波管性能的影响。更多还原

【Abstract】 The thermal analysis of the output segment of millimeter-wave TWT using ANSYS package is presented. The thinness of the pole shoe of PPM,the length of heatsink,the thermal silicone,and the height of the base had been studied for the temperature of the output segment.The results show that increasing the thinness of pole shoe, using longer heatsink,higher base,and Thermal silicone with higher thermal conductivity,and making heatsink and base be contacted compactly,would decrease the temperature of the output segment.All the methods would reduce the effect of temperature to millimeter-wave TWT.更多还原
