CONDENSER-EVAPORATOR Russian patent published in 1994 - IPC

Abstract RU 2013749 C1

FIELD: heat engineering. SUBSTANCE: ends of tubes are round in section and their center portion is star-shaped. Inner surfaces of tubes are covered with water-repelling coating. Condensing heat-transfer agent (liquid oxygen) flows to inter-tube space. Nitrogen vapor is condensed on inner surfaces of tubes and flows down giving up the condensing heat to the heat-transfer agent. EFFECT: enhanced efficiency. 2 cl, 2 dwg
