KOCHETOV FAN COOLING TOWER Russian patent published in 2017 - IPC F28C1/00 

FIELD: power engineering.

SUBSTANCE: invention relates to contact coolers, in particular, to cooling towers, and can be used at thermal power stations for recirculating water cooling. Fan cooling tower contains housing, spraying device, fluid collection tank and fan, wherein housing consists of two parts, upper part including sprinkler and drop separator, between which spraying device manifold with whole flare nozzles is arranged and lower part, in which cooled water collecting water sump tank is arranged with installed on it fan, wherein housing is made of thin-sheet stainless steel, and in liquid collection tank there is diffuser, which is part of housing and connected to fan, made with plastic impeller and multi-speed motor, depending on weather conditions, during operation allowing to, change of cooling tower performance due to change of air flow rate, and sprinkler is made in form of module from polymer cellular tubes layers, tubes are made cylindrical, arranged in all layers parallel to each other and welded between each other in contact points at module ends, wherein each tube cavities and intertubular space is filled with nozzle, droplet separator represents corrugated perforated sheets assembled in package, at edges fixed by frame, in form of vertical rigidly interconnected rods. Nozzle is made in form of cylindrical ring, on side, inner and outer surfaces of which screw thread is made, or in form of ball, on surface of which semi-spherical shaped blind bores are made, or in form of cylindrical ring, on side, inner surface of which partitions are fixed in form of washers with holes perpendicular to ring axis, which axes are asymmetric to ring axis, or in form of inscribable into circle unit, consisting of seven interconnected by lateral faces hexagonal parallelepipeds without upper and lower bases.

EFFECT: technical result is cooling tower performance improvement.
