“…The LHP was developed and tested in 1972 in the former Soviet Union [1]. The development of LHPs was a response to the challenge of the increasing needs of electronic systems, and with the specific demand of aerospace technology, which requires high operational reliability and robustness [2][3][4][5][6][7][8][9][10]. The two-phase loops offer many advantages over heat pipes [1,11] in terms of operation against gravity, maximum heat transport capability, smoothwalled flexible transport lines, and fast diode action.…”
