Testing of a Liquid Metal Carbon-Carbon Heat Pipe

Development of Lightweight Radiators for Lunar Based Power Systems

“…Further details on the fabrication and assembly of the heat pipe, using the originally available T-300 C-C composite for the finned shell have been reported previously [9,10]. A 35 cm long heat pipe with 2.5 cm wide fins was successfully tested [11] , starting from room temperature with the potassium working fluid in the frozen state to temperatures near 700 K. Figure 1 (b) shows a sketch of the instrumented test article.…”
