Design and Development of Cryogenic Turbo Refrigerator Systems
Abstract
This Phase C final technical report describes the analysis, design, and manufacturing work directed toward the advanced development of a miniature cryogenic turbo refrigerator for cooling infrared sensors, superconducting elements, and electronic devices. An important goal of the program is the demonstration of long life (30,000 hours) and maintenance-free operation, with a 5000-hour endurance test. The refrigeration requirement for the turbo refrigerator is: 1.5 watts at 12 K; and 40.0 watts at 60 K. During this report period, the design of the components and the complete system has been completed. Manufacture and final testing of the cryogenic heat exchanger was completed, and substantial testing has been conducted with the cryogenic turboalternators. Most of the parts of the centrifugal compressors are near completion. From the analysis, design studies, and tests conducted to date, it is concluded that the long-life, cryogenic turbo refrigerator system can be constructed to satisfy contract goals with respect to input power levels.
