METHOD OF OPERATION OF THERMAL PIPE Russian patent published in 1994 - IPC

FIELD: heat engineering. SUBSTANCE: in course of operation of thermal pipe, hydraulic resistance of capillary passages of the condensate line is regulated. To this end, heat-transfer agent is locally heated in them (sector by sector) to boiling point. Vapor phase is condensed in section between the evaporation zone and local heating by means of external cooling. Local heating and cooling are effected by supplying the heat from the source of the evaporation zone and removing the heat to the cold source of the condensation zone. EFFECT: enhanced efficiency. 3 cl, 3 dwg
