Lithium Emitter Heatpipe Research at Phillips Laboratory Power and Thermal Management Division.
Abstract
The purpose of the Li-EHP test was to experimentally demonstrate whether or not the Li-EHP is capable of creating uniform temperature conditions on the emitter surface of a THPM. To do so required the fabrication of a suitable vacuum system, a vacuum furnace which was capable of producing sufficiently high temperature (1800-200K) to initiate heat pipe action, and a means of acquiring extremely high temperature data. Instrumentation was selected which would enable the experimenters to measure the temperature at several locations on the exterior of the Li-EHP so that temperature differentials could be obtained which would indicate performance of the heat pipe. In addition1 the same tests performed on the Li-EHP were also performed on a molybdenum tube of approximately the same dimensions as the Li-EHP. Ultimately, Phillips Lab sought to simulate extremely non-uniform heat source conditions as a strenuous test of the Li-EHP capabilities. (MM)
