Development of Improved 1500 W Deployable Radiator with Loop Heat Pipe 2000-01-2458
Two-phase capillary loops are being extensively studied as heat collection and rejection systems for space applications as they appear to satisfy several requirements like low weight, low volume, temperature control under variable heat loads and/or heat sink, operation on ground and 0-g, simple mounting and heat transfer through tortuous paths.
A Deployable Radiator with Loop Heat Pipe (LHP) with a heat transport capability of 1500 W has been defined and conceived by Alenia, and developed by Lavochkin Association under Alenia contract.
In this paper a detailed description of the Deployable Radiator (and of its 1000 W LHP precursor) is presented, with emphasis on the areas that required research activities to improve performances.
