螺旋线慢波结构散热性能的理论研究

Theoretical Study on the Heat Dissipation Capability of the Helix Slow-Wave Structure

建立了二维研究模型和一维近似模型,通过不同的方法对螺旋线慢波结构进行理论热分析。得到慢波结构中螺旋线、夹持杆和管壳温度差的表达式。对特定的结构进行热分析,比较了各种方法得到结果的一致性。该项理论研究对改善螺旋线行波管散热性能具有重要的意义。

The thermal conduction of the helix slow-wave structure(SWS)has been studied theoretically in various different methods,with the established three-dimensional model and one-dimensional model.The expressions of the temperature differences of the SWS components have been obtained.The theoretical methods pursued have shown excellent agreement in the thermal analysis of a certain SWS.This theoretical thermal study would be a great aid to the capability improvement of helix TWT.
