The CryoTel® DS 1.5 is a split type Stirling cryocooler which was developed by Sunpower for systems requiring compact size, high efficiency, and high reliability. The DS 1.5 has a lift of about 1.4 watts at 77 K with 30 watts of input power. The cooler design includes gas bearings on the pistons and displacer for non-contact operation, and achieves low vibration by using dual opposed pistons...

Poster Presentation
Cryogenic cooling systems for HTS electric power devices require a reliable and efficient high-capacity cryocooler. A Stirling cryocooler with a linear compressor can be a good candidate. It has advantages of low vibration and long maintenance cycle compared with a kinematic-driven Stirling cryocooler. In this study, we developed dual-opposed linear compressor of 12 kW electric input power...

A novel type of the PZT based compressor operating at mechanical resonance, suitable for pneumatically-driven Stirling-type cryocoolers was developed theoretically and built practically during this research. A resonance operation at relatively low frequency was achieved by incorporating the piezo ceramics into the moving part, and by reduction of the effective piezo stiffness using hydraulic...

Poster Presentation
The linear compressor providing powers for the Stirling-type pulse tube Cryocooler (SPTC) is endowed with remarkable merits such as high reliability and long life which have a strong appeal to aerospace applications. The pulse tube cold finger (PTCF) exerts evident and complicated influences on the compressor’s performance. However, there is seldom systematic investigation on the influences,...
