THERMAL PIPE WITH FORCED CIRCULATION OF FLUID Russian patent published in 2008 - IPC H05K7/20 

FIELD: heating.

SUBSTANCE: between heat-releasing zone and fluid pipeline there is a check valve, partition made of finely porous material or capillary section of pipeline, fluid pipeline has tapping in the form of accumulation pipeline tightly sealed from one side, which is equipped with device of periodical heating up to temperature, which is higher than the temperature of heat-releasing section and periodical cooling down to the temperature, which is lower than the temperature of heat-releasing section. Shape and dimensions of section of fluid and accumulating pipelines provide the possibility to move steam and fluid mixture in the mode, in which portions of liquid are moved along pipeline together with the steam plugs without exfoliation into separate steam and fluid flows.

EFFECT: provision of controlled return of fluid from condensation zone into one or several evaporation zones independently on orientation in the field of gravity force.
