Development of a linear compressor for two-stage pulse tube cryocoolers

A valveless linear compressor was built up to drive a self-made two-stage pulse tube cryocooler. With a designed maximum swept volume of 60 cm^3, the compressor can provide the cryocooler with a pressure volume （PV） power of 400 W. Preliminary measurements of the compressor indicated that both an ef...

Description
Summary:A valveless linear compressor was built up to drive a self-made two-stage pulse tube cryocooler. With a designed maximum swept volume of 60 cm^3, the compressor can provide the cryocooler with a pressure volume （PV） power of 400 W. Preliminary measurements of the compressor indicated that both an efficiency of 35%-55% and a pressure ratio of 1.3-1.4 could be obtained. The two-stage pulse tube cryocooler driven by this compressor achieved the lowest temperature of 14.2 K.
