Cryocooler interface sleeve

摘要

A sleeve assembly for thermally interconnecting a pulse tube, two stage cryocooler with a superconducting device includes a heat transfer cylinder, a heat transfer receptacle and a wall extending therebetween to define a passageway. The heat transfer receptacle is formed with a tapered recess wherein a tapered cooling probe of the cryocooler is urged against the heat transfer receptacle to establish thermal communication therebetween. A cooling element of the cryocooler is disposed in the heat transfer cylinder to establish thermal communication therebetween. In operation, the cryocooler moves relative to the sleeve assembly between a first configuration wherein the cryocooler is engaged with the sleeve assembly to establish thermal communication therebetween and a second configuration wherein the cryocooler is disengaged with the sleeve assembly. An expandable bellows which interconnects the cryocooler with the sleeve assembly will maintain thermal insulation therebetween when the cryocooler is disengaged from the sleeve assembly.
