It was demonstrated that a multiple evaporator LHP can successfully operate as a thermal control system component. A breadboard LHP with multiple evaporators (two) that retained the reliable self starting behavior of the single thermal interface LHP was developed. Program efforts were concentrated on a two pump system and investigated the performance of the dual evaporator LHP. Analytical predictons and experimental test data are compared, and important issues are discussed that will be a baseline for continued development of multiple thermal interface LHPs. All of the conclusions are based on test results, analytic modeling and the correlation of the two. Although a mathematical model that predicts the multiple evaporator LHP behavior was developed, the primary focus of the program was the development, fabrication, and test of a breadboard multi-evaporator LHP. The program clearly demonstrated that multi-evaporator LHPs are feasible and merit further development as a viable thermal control components |
