设备用途:

快速温度变化试验箱广泛用于航空、航天、电子电工产品、仪器仪表、材料、零部件、设备等做快速温度变化试验以及应力筛选试验,也可做加速湿热试验、交变湿热试验、恒定湿热试验及高低温例行试验、耐寒试验、低温储存等,以便对试验中拟定环境条件下的性能、行为作出客观分析及评价。

满足标准:

MIL-STD-2164、GJB-1032-90电子产品应力筛选
MIL-344A-4-16电子设备环境应力筛选
MIL-2164A-19电子设备环境应力筛选方法
GJB/Z34-5.1.6电子产品定量环境应力筛选指南
GJB/Z34-5.1.6电子产品定量环境应力筛选指南
NABMAT-9492美军海军制造筛选


制冷原理:

快速温度变化试验箱高低制冷循环均采用逆卡若循环,该循环由两个等温过程和两个绝热过程组成。其过程如下:制冷剂经压缩机绝热压缩到较高的压力,消耗了功使排气温度升高,之后制冷剂经冷凝器等温地和四周介质进行热交换,将热量传给四周介质。后制冷剂经阀绝热膨胀做功,这时制冷剂温度降低。最后制冷剂通过蒸发器等温地从温度较高的物体吸热,使被冷却物体温度降低。此循环周而复始从而达到降温之目的。
