THERMAL TUBE Russian patent published in 2003 - IPC

FIELD: power engineering and thermal physics; manufacture of heat-transfer thermal tubes, mainly energy stressed tubes. SUBSTANCE: proposed thermal tube includes hermetic housing heated in evaporation zone and cooled in condensation zone. Arranged inside said housing at spaced relation to its inner wall is capillary structure made in form of at last one layer of screen or perforated shield. At least two flexible longitudinal partitions are tightly mounted in evaporation zone in clearance between inner wall of housing and outer surface of capillary structure. Said partitions may be trough-shaped in form and may be made from foil at smooth pitch. Proposed thermal tube excludes shutting- off of liquid flow due to boiling of heat-transfer agent. EFFECT: enhanced efficiency. 4 cl, 4 dwg
