Modeling and test results for two loop heat pipes with a freeze-tolerant condenser

摘要

This paper describes modeling and test results for a two Loop Heat Pipes (LHP) with a condenser designed to be used in a deployable spacecraft radiator system. These units were provided by the two major commercial US vendors of LHPs. The condenser used is a freeze-tolerant, parallel-flow design based on the International Space Station (ISS) deployable radiator design. This condenser allows the deployable radiator to be utilized without freeze- protection heaters.
