【摘要】 高低温冲击试验箱是一种提供高温、低温的环境设备。主要用于机械、电子、电工等领域的一些产品进行高温、低温环境的性能测试、筛选或考核实验。进行了高低温冲击试验装置结构及其制冷系统设计,利用具有精馏装置的自然复叠式制冷循环系统获得冷源,使用R22/RZ3混合工质,低温室内温度可到达-70℃,实现宽范围的温度自动调节。试验箱执行《温度冲击实验》(GJB150.5-86)技术标准,可以满足温度冲击试验的需求。更多还原

【Abstract】 The thermal shock chamber is a kind of environmental test chamber that can provide the environment of high temperature and low temperature, which is mostly applied to performance testing or examination for machine product、 electron product and so on.This paper mainly deals with the design of a chamber for thermal shock chamber , which performs a new auto- cascade cycle that employs a rectifying column and used R22 and R23 as the zeotropic mixture refrigerant, the temperature of a tow- temperature chamber decreased to - 70℃, diffusely adjust the area of temperature.The chamber obey 《Thermal shock test》(GJB150.5 - 86)technic standard, the thermal shock chamber can satisfy countryside exigent requirement.更多还原
