摘要： An improved pulse tube cooler having a resonator tube connected in place of a compliance volume or reservoir. The resonator tube has a length substantially equal to an integer multiple of 1A wavelength of an acoustic wave in the working gas within the resonator tube at its operating frequency, temperature and pressure. Preferably, the resonator tube is formed integrally with the inertance tube as a single, integral tube with a length approximately 1A of that wavelength. Also preferably, the integral tube is spaced outwardly from and coiled around the connection of the regenerator to the pulse tube at a cold region of the cooler and the turns of the coil are thermally bonded together to improve heat conduction through the coil.

摘要： A multi-stage cryocooler (100) includes a concentric second-stage pulse tube expander (130) in which a pulse tube (132) is located within a second-stage regenerator (131). In one embodiment, an inner wall of the regenerator also functions as an outer wall of the pulse tube. In another embodiment, there is an annular gap between an inner wall of the regenerator and an outer wall of the pulse tube. The gap may be maintained at a low pressure, approaching a vacuum, by placing the gap in fluid communication with an environment around the cryocooler, such as the low-pressure environment of space. The integrated second-stage structure, with the pulse tube within the annular regenerator, provides several potential advantages over prior multi-stage cryocooler systems.

摘要： The invention relates to a device for the recondensation by means of a cryogenerator of low-boiling gases of the gas evaporating from a liquid gas container. The inventive device comprises one or at least two continuous cooling stages, the so-called cold top. Every stage is a pulse tube cooler whose heat transfer between the regenerator and the pertaining pulse tube is embedded in an exposed cold surface. The entire cold top is flanged only on the outer recipient of the device and projects into the interior in the neck tube of the device. The last cold surface of the cold top is located at the end of the neck tube and is exposed in the vapor room above the liquid gas cold bath. The other cold surfaces are opposite a heat transfer ring mounted on the neck tube. The respective opposite front faces engage with each other without contacting each other in any place while forming a gap so that a free passage is guaranteed from the vapor room via the liquid gas bath to the flange of the cold top in the neck tube. The two components regenerator, pulse tube of every pulsed tube cooling stage are covered with a heat shield that can be a poorly thermoconductive covering only resting thereon or an annular vacuum chamber whose outer wall contacts the sheathing component only in certain positions or only across short distances in a linear manner.

摘要： A pulse tube expander (70) includes a regenerator (30), a pulse tube (42), a porous plug phase shifter (74), and a surge tank (60), in series gaseous communication with each other. The porous plug phase shifter (74) is made of a porous material such as a sintered mass or a packed solid bed of distinct, free-flowing bodies (84). The porous plug phase shifter (74) introduces a phase shift between the pressure wave and the mass flow rate in the pulse tube expander (70). The porous plug phase shifter (74) is resistant to clogging due to contaminication that may be present in the system.
