摘要: 热真空环模试验设备是专项设备,应用面相对比较窄,加上不同的被试件各自的特殊要求,因此在设计方面很难使用统一的标准。对热真空环模试验设备设计中的真空室与热沉最小尺寸确定和表面处理、冷管引入的真空密封结构、热沉的结构确定和设计计算、真空抽气主泵选择、加热形式的选择以及加热器的位置、制冷方式选择和温度循环设计、设备程序控制等有关问题,结合热真空试验技术特点提出见解,同时简介了所研制的热真空环模试验设备的简况。还对热真空环模试验设备的检测项目、检测方法进行了论述。Abstract: The vacuum environment equipment is for special use in industry.It hasn’t have centralized standard in designing for its narrow application and usually different products have different requests.With the characterization of the vacuum testing technique,it points out the view of vacuum chamber designing in vacuum environment equipment and to confirm the minimum size of the shroud and its cover-processing.It also discuss the problem of vacuum air-proof construction which has refrigerant tube.The constructive of the shroud and its calculating in design are confirmed.Choosing throughout of vacuum main pump,heating way,the position of the heater,cooling way,thermal circling design and service proceeding control are designed.Some brief condition in researching and producing the equipment are introduced.Others like the equipment’s testing program and methods have been narratived.
