摘要
A Stirling cycle cryocooler is disclosed that includes a displacer unit having a cold end and a hot end. The displacer unit (4) 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 (18) and is slidable with respect to the lengthwise axis of the housing (10). The displacer unit also includes a regenerator unit (14). A heat acceptor (20) is affixed to the cold end of the displacer unit (4). The heat acceptor (20) transfers heat from a device such as a High Temperature Superconducting Filter to a gas such as helium located within the displacer unit (4). The heat acceptor (20) preferably includes a radial component (22) with an annular component (24). The heat acceptor advantageously decreases the heat transfer resistance between the heat acceptor and the helium gas. The Stirling cycle cryocooler is thus able to operate with reduced input power to achieve a desired lift level.
