Abstract
Abstract In a gas-controlled heat-pipe thermostat of high precision having a temperature-controlled chamber arranged at least partly within the evaporation and condensation cycle and a gas reservoir connected to said heat-pipe, the improvement comprising in that in the heat-pipe a cooling surface is arranged for the production of condensate which, for the scavenging of the surface of said temperature-controlled chamber in a directed manner, is connected to the outer wall of said chamber by liquid conducting capillary structures.
