CIRCUIT HEAT PIPE Russian patent published in 1997 - IPC

FIELD: thermal engineering including cooling systems of heat-transfer devices. SUBSTANCE: heat pipe has evaporators 1,2 and condenser 3 joined together by steam and condensate pipings 4 and 5. Porous capillary nozzles 6,7 have feed channels 8,9 and steam outlet channels 10. Expansion cavity 11 forms bound space with feed channels of porous capillary nozzles of both evaporators. Fedd channels of nozzles are connected through auxiliary capillary structure 12 to expansion cavity 11. Various options of auxiliary capillary structure are available. EFFECT: improved reliability of make-up of evaporator feed channels due to organizing separate flow of steam and liquid in them so that steam bubbles escaping them do not interfere with countercurrent flow of liquid. 8 cl, 11 dwg
