摘要： A radiator system uses an innovative passive control scheme in combination with dependable mechanical design features to meet or exceed the requirements for orbital applications. The disclosed radiator system is unique because we target an extremely high turndown ratio of 200:1 with an entirely passive two-phase pumped loop using ammonia as the working fluid. Sections of the radiator will selectively freeze to assist the turndown, and the mechanical design of the radiator can handle the high pressures experienced during such freezing and thawing events.

摘要： A vapor compression system control implementations that maintain surface temperature uniformity of at least one cold plate throughout pulsed thermal loads from a minimal or zero load state suddenly to a high or 100% of design capacity state where the heat pulse occurrence, frequency, and durations are not known a priori. Vapor compression system control implementations that maintain surface temperature uniformity of at least one cold plate throughout pulsed thermal loads from a minimal or zero load state suddenly to a high or 100% of design capacity state where the heat pulse occurrence, frequency, and durations are not known a priori. Rapid thermal pulse applications require a robust control strategy of the cold plate assembly to maintain cold plate surface temperature uniformity. In one implementation, a control system for the cold plate assembly that maintains a uniform cold plate temperature given controlled supply and suction conditions is contemplated.

摘要： An apparatus holds or stores at least one vial containing a vaccine or other material to be cryogenically preserved. The method passively regulates the rate of cooling for vaccines or other cryopreserved materials by using the enthalpy of fusion of at least one phase-change material (PCM) to control the rate of cooling when subject to a low temperature or cryogenic storage environment.
