一种带散热片的螺旋线慢波结构的热模拟与分析

Simulation of Thermal Analysis for Helix TWT Slow-Wave Structure with Radiator

为了解决慢波结构的散热问题,本文从热特性的角度出发设计了两种散热片结构。利用有限元软件ANSYS对带有这两种散热结构的慢波结构的热特性分别进行了模拟和分析,通过比较发现集中散热结构具有较好的散热性能,这为螺旋线行波管的优化设计和合理散热提供了参考。

In order to solve the heat dissipation of slow-wave structure,we design two types of radiators according to the thermal performance.The thermal analysis for helical travelling wave tube（TWT） slow-wave structure with radiators is respectively simulated by ANSYS in the article.By comparison,the concentrated cooling structure is better,which provides references for optimization design and logical cooling of space TWT.
