METHOD OF OPERATING DRIP REFRIGERATOR-EMITTER (VERSIONS) Russian patent published in 2014 - IPC B64G1/50 F28D21/00 

FIELD: heating.

SUBSTANCE: group of inventions relates to methods of removal of low-grade heat from the power systems of spacecrafts (SC). The method of operating a drip refrigerator-emitter (DRE) comprises heating the coolant, its transformation into a stream of droplets cooled by radiation in outer space, collection of droplets and feeding the condensate to the power system. In the first embodiment, the stream of droplets is affected by the external electric field, the parameters of which are changed along the trajectory of flying of the SC. In the second embodiment, the stream of droplets is affected by the flow of charged particles, which parameters are changed along the trajectory of flying of SC. In the third embodiment, in the stream of droplets near their collection the gas is injected with low electric resistance. The injection intervals correspond to the time of charge accumulation on the droplet, and the injection rate is changed along the trajectory of flying of the SC. In the fourth embodiment, the gas with low electrical resistance is dissolved in the liquid coolant of DRE. Depending on the purpose of SC and parameters of DRE it is possible to use each of the proposed methods of operating DRE, or any their combination.

EFFECT: decrease of defection of droplets from straight-line trajectories and thus reduction of loss of coolant to ensure more efficient and reliable operation of DRE.
