AIR COOLER Russian patent published in 2023 - IPC F28D9/00 F28D9/04 F28D7/04 

FIELD: heat exchangers.

SUBSTANCE: in the cylindrical body of the air cooler, along its longitudinal axis, one or several heat exchange units of a radial-spiral type are installed vertically back-to-back. In the lower part of the device, there is an air inlet chamber, in which the following components are placed bottom to top: an air inlet pipe into the device, louvers for regulating the amount of air supplied to the device, and a device for humidifying the air. Air is supplied by an axial or centrifugal fan. In the upper part of the cooler, there is a heated air outlet chamber, above which an L-shaped deflector freely rotating around the axis of the apparatus is installed. A weather vane is fixed on the deflector by means of a rigid connection, which, under the pressure of the wind, rotates the deflector so that the outlet of heated air from the deflector is directed in the direction of the wind.

EFFECT: eliminating the possibility of freezing of the components of the cooled medium at negative ambient temperatures, increasing heat transfer intensity.
