Paper Abstract

A gravity-type heat pipe blackbody source is described. The simple construction of the pipe involves condensed liquid flowing back to the evaporation zone under gravitational influence. The temperature distribution of the cavity walls is very even, with a maximum temperature difference of less than 0.6 C. The effective distribution of the double-cone construction is calculated, and it is found that the effective emissivity at the working area is over 0.999.
