本文介绍辐射致冷器在环境模拟设备中作30K冷背景试验时有关温度测量方法的论述。为达到30K冷背景而采用了氖热管新技术来实现冷背景的方案,要检验热管设计计算的正确性与热管的实际效果,必须准确可靠地测出冷板的各部温度与热管冷、热端温度。全文分两部分。在温度布点和测量方法中对在低温和真空条件下采用铂电阻表面温度传感器,金铁—铜及铜—康铜热电偶综合手段的测量应用方法加以介绍,特别是对材料的选择、安装、布点方法、测量仪器的考虑、测温元件进行快速简易分度并制定出表格等方法。在试验结果和分析方面成功地验证氖热管的正常运行与30K冷背景的获得提供了数据与图表,其中有热沉温度变化,辐射致冷器各部温度变化,30K冷板降温状况及热管工作后性能变化等。
This article describes the radiation cooler in the environmental simulation equipment 30K cold background test on the temperature measurement methods discussed. To achieve the 30K cold background and the neon heat pipe technology to achieve a cold background of the program to test the heat pipe design and calculation of the correctness of the actual effect of the heat pipe must be accurately and reliably measure the temperature of the cold plate and the heat pipe cold and hot end temperature. The full text is divided into two parts. In the temperature distribution and measurement methods in the low temperature and vacuum conditions using platinum resistance surface temperature sensor, gold and iron - copper and copper - constantan thermocouple integrated measurement and measurement methods are introduced, in particular, the choice of materials, installation, Dispensing methods, the measurement instrument considerations, temperature measurement devices quickly and easily indexing and develop a form and other methods. The experimental results and analysis of the successful verification of the normal operation of the neon heat pipe and 30K cold background provides data and charts, including heat sink temperature changes, radiation cooler temperature changes, 30K cold plate cooling conditions and heat pipe work Performance changes.
