摘要
针对机组式高低温环境试验箱温度变化范围宽的特点,对机组式高低温环境试验箱进行了全新的设计。该环境箱采用复叠式制冷机组制冷,控温范围为-190℃^+400℃;高低温箱分体式设计,防止高温损坏蒸发器;设计了制冷量调节结构。
According to the characteristics of high-low temperature environmental test chamber which has wide temperature range, a new high-low temperature environmental test chamber is designed. The environmental test chamber adopts cascade refrigeration, and its cooling capacity is—190℃- ＋400℃. The high-low temperature environmental test chamber is designed in split style, which can prevent the high temperature from damaging the evaporator. The refrigeration quantity adjusting structure is designed.
