不同方法装配的慢波系统的散热稳定性的研究

Study on the Heat Dissipation Stability of Slow-Wave Structures Assembled Differently

外部条件和工艺处理会对不同方法装配的慢波系统的散热稳定性产生影响。利用计算机模拟的方法,分析比较了当外部条件变化时,慢波组件散热性能的变化情况。冷弹压组件在应对外部条件变化时,表现出较好的散热稳定性。利用实验测试的方法,考察了制管工艺处理对慢波组件散热性能的影响作用。当进行各种制管工艺处理时,焊接组件和热挤压组件均表现出较好的散热稳定性。得到的结论对螺旋线行波管的制备具有重要的参考意义。

The heat dissipation stability of different assembled slow-wave structure（SWS） is studied,and the effects of the outside thermal condition and the TWT（travel wave tube） manufacturing process have been accounted for.ANSYS has been used to analyze the variation of the heat dissipation capability of the SWS under different outside thermal conditions.The cold-stuffed SWS exhibits better heat dissipation stability to the variation of the outside condition.Several experiments have been implemented to study the effect of the TWT manufacturing process on thermal conduction of the SWS.The hot-inserted SWS and the brazed SWS exhibit excellent heat dissipation stability to the manufacturing process.Several conclusions obtained are expected to aid the helix TWT design.
