Performance Characteristics of a High Intensity Cryogenic Flow Boiler 2003-01-2507

Hamilton Sundstrand has been working on the development of a new cryogenic flow boiler based on its patented compact, high-intensity cooler (CHIC) technology intended to provide low weight and volume and overcome freezing problems associated with cryogen use in EVA spacesuit cooling. Tests of the prototype device resulting from that effort have now been completed. The test data demonstrate that the design is extremely resistant to freezing the heat transport fluid as anticipated. Highly effective heat transfer is achieved in a compact device combining the functions of several conventional heat exchangers. This novel heat exchanger, a “normal flow” layered impingement arrangement should provide a very compact solution to any heat transfer applications where the cold fluid operates below the warm fluid's freezing point. Test results are generally consistent with design analyses for the prototype.
