摘要
小型脉冲管制冷机在空间以及军事领域有广泛的应用前景,通过提高制冷机的工作频率可减小制冷机的体积与质量。研制了1台重1.6 kg的脉冲管制冷机并进行了实验优化。采用实验室研制的小型直线压缩机驱动,惯性管气库、双向进气作为调相机构,在输入电功45 W,冷端温度80 K时可获得2.12 W的制冷量,相对卡诺效率13.0%。由于运行频率高,冷指尺寸小,冷指降温时间短,2 min降温到80 K,并且冷头温度受重力影响较小。
Increasing the drive frequency can yield a more compact pulse tube cooler,which is very attractive for many applications,especially for the space and military applications.In this paper,experimental study has been carried out for a coxial pulse tube cryocooler which is driven by self-designed linear compressor and uses an inertance tube with a reservoir and double-inlet value as the phase shifter.The pulse tube cryocooler has achieved cooling capacity of2.12W at80K with the input power of45W,around of13%relative Carnot efficiency is achieved at80K when the reject temperature is300K.Because of the low mass and the high operating frequency,the temperature of the cold end can decrease to80K from300K in two minutes and the gravity has little effects on the temperature.
