Design Study of an Experiment Cooling System With Liquid/Air Heat Exchange for Spacelab Payloads (ECLA)

摘要

The potential of fluid loops as active thermal control systems for spacecraft has been investigated previously. In this report the results are presented of a small, more detailed study of a particular fluid loop which will be used on Spacelab. Its purpose is to control the temperature of experiments by the judicious removal of heat by means of a liquid coolant which circulates in a closed loop and to transfer this heat to the Spacelab's avionics air loop. A modular liquid/air cross flow heat exchanger constitutes the thermal link between coolant and air loops.
