Experimental Study on a New Low-temperature System for Cryomicroscope[J]. Journal of refrigeration, 2011, 32(3). DOI: 10.3969/j.issn.0253-4339.2011.03.053.
which takes nitrogen as a cold source and utilizes a micro-throttle refrigerator to cool the nitrogen
is presented for satisfying the temperature-drop demands of cryomicroscope.An elementary diagram of cryo-microscope's novel cold source system is given.To determine the parameters of throttle tubes(internal diameter and length)
the optimum throttling pressure
temperature drop
the refrigerating capacity and nitrogen consumption
three experiments was conducted.The results show that the internal d...
