摘　　要：红外探测器的杜瓦组件采用真空钎焊加工,钎焊设备的隔热效果影响杜瓦组件焊接的一致性。以全金属反射屏真空钎焊设备为研究对象,研究了真空钎焊设备热辐射理论,通过有限元仿真分析软件对真空钎焊设备升温过程进行数值模拟计算,分析升温过程反射屏温度分布及各层温度变化规律。优化确定了钎焊设备的反射屏厚度和层数的参数,保证较好的隔热保温性能同时可有效节约成本。可为其它真空钎焊设备的加热室设计提供参考依据。The Dewar component of the infrared detector is processed by vacuum brazing,and the insulation effect of the brazing equipment affects the consistency of the Dewar component welding.In this paper,the thermal radiation theory of vacuum brazing equipment is studied,and the temperature rise process of vacuum brazing equipment is numerically simulated by finite element simulation software.The parameters for the thickness and number of layers of the reflective screen of the brazing equipment have been optimized and determined,ensuring good insulation performance while effectively saving costs.This article can provide reference for the design of heating chambers for other vacuum brazing equipment.
