Abstract:

A variable conductance, two inch diameter, sixty inch long heat pipe was designed and constructed. The performance characteristics of the heat pipe while operating in both the conventional and variable conductance modes were studied. In particular, the ramifications of using a non-condensible gas which was more than twice as heavy as the working fluid were closely observed with the heat pipe being oriented both horizontally and vertically. Power inputs to the heat pipe were varied from twenty-five to one hundred fifty watts. Methanol was selected for use as the working fluid and krypton was used as the non- condensible gas. Condenser temperature profiles and liquid crystal photographs are presented for the various operating modes.
