Abstract: Drawn polymer fibers have internal channels running, at least partially, through the length of the fibers. These fibers may be configured to for use as thermal isolators that can thermally isolate material at the central core of the fiber from the outside environment. In such instances, the channels may be used as insulating channels and/or a heating or cooling fluid can be pumped through the channels to maintain the temperature of the material at the inner core. As another application, the fibers may be used as recuperative, regenerative, parallel-flow, counter-flow, cross-flow or condenser/evaporator heat exchangers. In this case, the channels may be used to direct fluid flow. The fiber may allow for the exchange of heat between fluids in the channels.

The dilution refrigerator includes a plurality of thermalization plates configured to be cooled to a plurality of temperatures, and a first thermalization plate of the plurality of thermalization plates includes an integrated heat exchanger. The integrated heat exchanger includes channels formed in the first thermalization plate, and the channels are configured to allow helium to flow through the first thermalization plate during operation of the dilution refrigerator to improve heat exchange and cooling power of the dilution refrigerator.

Abstract: A distributed refrigeration system is provided. The distributed refrigeration system comprises a pre-cooling system configured to be thermally coupled to two or more cryogenic devices and to provide a first cooling stage to the two or more cryogenic devices. The two or more cryogenic devices may be two or more of a dilution refrigerator, a low-temperature microscopy system, a 3He refrigeration system, and/or a superconducting CMOS system.
