Emerging Technologies for Cryocooler Interfaces

New technologies are emerging for improved interface designs for advanced cryocooler applications. Advanced cryogenic heat pipes are being developed for low temperature heat transport systems. These devices are typically designed to attach to a cryocooler or heat sink device at one end and a heat load at the other end. Several test units have been developed for aerospace applications, and have recently been tested in microgravity. An acetone heat pipe interface was developed for interfacing between a refrigerator air volume at 250K and a Stirling cooler heat sink. A nitrogen heat pipe was developed for heat transport in microgravity at temperatures between 65 K and 115 K. Both of these units were flight tested in 1994 on the Space Shuttle (STS).

Further development is being pursued to develop heat transport systems for cryocooler interfaces. Ongoing development includes an adaptation of the Russian loop heat pipe technologies, as well as improved interfaces for Space Station refrigerator/freezers. Technologies proposed for development include quick-cooling cryogenic heat pipe interfaces, development of redundant pressure containment envelopes for cryogenic heat pipes, and evaluation of additional low temperature working fluids. Availability of these technologies to the cryocooler community will significantly simplify designs and open new applications for cryocooler-based systems.
