THERMOSIPHON HEAT EXCHANGER Russian patent published in 1997 - IPC

FIELD: engineering. SUBSTANCE: heat exchanger consists of two zones. Heat-exchanger surface is made in form of condensing zone - loop-shaped finned heat exchange tubes with combined upper ends. Lower ends of heat-exchange tubes are deepened inside evaporation zone housing. Ratio of lengths of deepened tubes to their loop-shaped sections ranges from 0.01 to 0.08 at ratio of volumes of additional evaporating and condensing zones more than 0.012 or less than 0.036; ratio of sections of tubes introduced into evaporation zone housing to loop-shaped section is equal to 0.012-0.036. EFFECT: enhanced efficiency. 2 cl, 2 dwg
