概述设计、试验和制造了一种冷却宇宙飞船上用的行波管的热控制系统。设计的这种系统显示出能用散热管提供一些高热导通道,把行波管收集极上耗散的750瓦功率传到平板辐射器上,在此处再将热量辐射到空间去。四个散热管组成的蒸发器和行波管收集极,与固定在辐射器中央的一个传热块相連。导热管冷凝器沿着方形辐射器板对角线放置,以便在对角线上几乎保持等温,达样散热片效率就高。本文给出的试验结果,指出在不同功率耗散下热控制系统的几种散热工作方式。给出了在一个,两个,三个或四个散热管全部损毁时
Overview Design, test and manufacture of a thermal control system for traveling traveling wave tubes used in spacecraft. This system was designed to provide some high thermal conductivity ducts with heat pipes to dissipate 750 watts of power dissipated on the collector of the traveling wave tubes to the flat radiators where they were radiated into space. Evaporator and TWT collector composed of four radiating tubes connected to a heat transfer block fixed in the center of the radiator. The heat pipe condenser is placed diagonally along the square radiator plate so as to maintain almost the same diagonal temperature and the efficiency of the sample heat sink is high. The experimental results presented in this paper point out several operating modes of heat dissipation system under different power dissipation. It is given when one, two, three or four heat pipes are completely destroyed
