REFLUX Russian patent published in 2016 - IPC F28B1/06 F28B9/00 

FIELD: energy.

SUBSTANCE: reflux exchanger comprises two stages connected in series, herewith the first stage is shaped as a partial condenser with air cooling, and the second stage includes a bunch of generally horizontal smooth or finned tubes, which can be operated by choice either in dry air cooling mode or in wet evaporative cooling mode, herewith the partial condenser with air cooling is an A-shaped air-cooled condenser, with multiple finned tubes passing throughout the two opposite sides to create an A-shaped or an inverted A-shaped structure, and a bunch of horizontal tubes located at the center in the upper part of the condenser in case of the A-shaped structure and in the lower part of the condenser in case of the inverted A-shaped structure, and one or several fans intended to assist the ascending air flow in the heat exchange tubes and in the direction of the tubes bunch.

EFFECT: invention allows to improve thermal characteristics during high ambient temperatures periods.
