摘要

Loop Heat Pipe (LHP) based thermal management systems is proposed for thermal control of experimental setups and associated avionic packages aboard upper stage of a launch vehicle. A general design procedure for LHP is presented, for maximum expected power dissipation levels, radiator panel temperature and temperature constraints on the evaporator. As a first step towards realizing a customized LHP based system, a steady-state thermal model of flat evaporator LHP is developed and validated. Results for various working fluids are compared.
