ABSTRACT:
A gas-controlled heat-pipe thermostat of high precision comprising a closed pipe interiorly covered with a capillary structure; a gas pressure regulation system containing control gas in communication with the interior of the pipe and a working fluid. The pipe defines first and second condensation zones and an intermediate evaporation zone. The working fluid within the pipe upon reaching the evaporation zone is vaporizable and dividable into two portions, each portion flowable to one of the first and second condensation zones after which it returns to the evaporation zone by way of the capillary structure for recycling. The control gas of the gas pressure regulation system forms a buffer zone. The positioning of the evaporation zone in relation to the second condensation zone resulting in the evaporation condensation cycle through the first of the condensation zones is separated from the control gas by the evaporation condensation cycle through the second condensation zone.
