開敞型慢波線熱傳導的一維分析
ONE DIMENSIONAL ANALYSIS OF HEAT CONDUCTION OF THE OPEN-TYPE SLOW WAVE STRUCTURE
-
摘要: 在O型功率行波管中,慢波線的散熱性能決定了行波管的功率容量。本文根據熱力學的一維溫差方程,導出了由梯形橫截面介質桿支撐的開敞型慢波線的熱點與管殼之間的溫差,此溫差值決定了管子的功率容量。用求得的分析式對具體結構進行計算,求得的計算值與實測值相符。文中還給出了幾個彈壓型及焊接型慢波線的溫差數據作為分析比較,為慢波線的工藝設計分析提供了依據。

Abstract: In an O type high power travelling wave tube (TWT), its power capacity is determined by the heat conduction characteristic of the slow wave structure (SWS). When the open type SWS is supported by dielectric rods of trapezoid shape in cross section, the one dimensional equation of the temperature difference between the hot spot of the SWS and the barrel of the tube is derived in this article. The value of temperature difference determines the power capacity of the TWT. The equations obtained are then applied to analyze different kinds of practical open type SWS. Theoretical calculation is in good agreement with measurement. Some values. of temperature difference for several practical SWS, some of which are made by spring pressed, and some by brazing, are given for comparision and for use in technological design and analysis. -
