摘要： A cryocooler cold end assembly is disclosed. The assembly includes a unitary external, outer housing. By constructing the housing from a single unitary metal shell, part count is reduced from prior art assemblies. Additionally, all brazing requirements previously necessary to secure and seal the components are eliminated. Further, due to one or more machining steps subsequent to manufacturing/forming the external sealed housing, the tolerances are improved. This allows for shrink to fit assembly of several components and also results in improved straight-line accuracy between the piston bore and the displacer cylinder. Due to this latter improvement, the need for a displacer liner is eliminated.

摘要： A cryogenic receiver front-end includes a heat sink having a mounting surface and a plurality of fins, a cryocooler mounted to the mounting surface of the heat sink, a heat rejector surrounding the cryocooler, the heat rejector including a plurality of pliable c-shaped recesses therein, and a plurality of heat pipes. Each heat pipe has first and second ends, the first ends of the plurality of heat pipes are disposed in respective c-shaped recesses of the heat rejector. A working fluid is contained inside the heat pipes. The second ends of the plurality of heat pipes are thermally coupled to the heat sink. A weather resistant enclosure unit is mounted to the heat sink and encloses the components of the cryogenic receiver front-end.
