  • Single-fluid stirling/pulse tube hybrid expander
    Patent number: 6167707
    Abstract: A hybrid two stage expander having a first stage Stirling expander coupled to a second stage pulse tube expander. Both stages are pneumatically driven by a common reciprocating compressor in a typical application. The first stage Stirling expander provides high thermodynamic efficiency which removes a majority of the heat load from gas within the cryocooler. The second stage pulse tube expander provides additional refrigeration capacity and improved power efficiency with little additional manufacturing complexity since it has no moving parts.
