Stirling cycle cryocooler with optimized cold end design

摘要

The Stirling cryocooler includes a displacer unit (4) having a cold and a hot end which includes a cold cylinder housing and a displacer liner (18) disposed on the inner surface of the housing (10). A displacer assembly (12) lies within the displacer liner and is slidable with respect to the lengthwise axis of the housing. The displacer unit also includes a regenerator unit (14). A heat acceptor (20) is affixed to the cold end of the displacer unit and transfers heat from a device such as a high temperature superconducting filter, to a gas such as helium located within the displacer unit, and includes a radial component (22) with an annular component (24). An independent claim is made for a Stirling cycle cryocooler.
