KOCHETOV FAN COOLING TOWER Russian patent published in 2014 - IPC F28C1/00 

FIELD: power industry.

SUBSTANCE: fan cooling tower includes shell, spraying device, liquid collecting tank and fan. The housing consists of two parts, upper part with sprinkler and drop separator, between which a header of the spraying device with nozzles is located, and the lower part in which a water collecting tank is located for collection of cooled water with a fan installed on it; the housing is made from stainless steel sheets, and in the water collecting tank there is a diffuser that comprises a part of the housing and is connected to the fan provided with a plastic impeller and a multi-speed electric motor allowing changing the cooling tower capacity during operation, depending on weather conditions, by changing the air flow rate, and the drop separator is provided with triple corrugation, where the air flow changes direction for three times resulting in considerable reduction of drop entrainment, and each nozzle of sprinkler is made in the form of hollow shell out of two coaxial parts with axial symmetry: base and cover rigidly attached to each other by four latches, and inlet nozzle is fixed to the base tangentially and creates swirling pressure of discharge in the nozzle body, at the same time the cover is three-dimensional, with involute profile and central conical hole with a cone angle of 130° at the top, and the base is profiled, with a central fairing of the swirling flow formed by a conical surface transforming into a sphere at the top and directed towards the central conical hole in the cover, and the base of the conical surface is smoothly coupled with toroidal surface of the base.

EFFECT: improved operating efficiency of cooling tower.
