A cryogenic cooler is provided for use in craft such as launch, orbital and space vehicles subject to substantial vibration, changes in orientation and weightlessness. The cooler contains a small pore, large free volume, low density material to restrain a cryogen through surface tension effects during launch and zero-g operations and maintains instrumentation within the temperature range of 10°-140°K. The cooler operation is completely passive, with no inherent vibration or power requirements.
A cryogenic cooler for use in craft such as launch, orbital and space vehicles subject to changes in orientation and conditions of vibration and weightlessness comprising: an insulated tank; a porous open celled sponge-like material disposed substantially throughout the contained volume of said insulated tank; a cryogenic fluid disposed within said sponge-like material; a cooling finger immersed in said cryogenic fluid, said finger extending from inside said insulated tank externally to an outside source such as an instrument detector for the purpose of ...
