| Abstract: | In order to improve safety and reliability of single-phase fluidloop in long-life spacecraft,details of fluid freeze prevention,gas removal,pressure control,ESD prevention are presented and discussed in combination with some design experience at home and abroad.The emphasis is on fluid freeze prevention using a regenerative heat exchanger,gas removal at low pressure and pressure control with fluid expander and so on.And some design examples are given to verify this principle.Such results can provide guidance to enhance safety and reliability of fluid loop design in deep space exploration and space station. |
