Abstract

A miniature pulse tube refrigerator, split-type with a flexure spring compressor, was fabricated and tested. The miniature pulse tube was 5 mm diameter and 60 mm long. A stack of stainless steel mesh of #300 was used as a regenerator. Cooling performance of different pulse-tube refrigerator schemes, such as orifice, double inlet and modified, was studied. By using the compressor back-side volume as a reservoir and phase shifter, initial test demonstrated a cooling power of 0.16 W at 195 K for an input power of 6 W. A compressor was operated at a frequency of 50 Hz. The values of COP and FOM(% of Carnot) of the refrigerator were 2.42% and 1.20%, respectively.
