Abstract: FIELD: heat exchange.SUBSTANCE: invention relates to heat engineering and can be used for recirculating water cooling. Fan cooling tower includes exhaust tower with air inlet windows along perimeter of its lower part, water trap, water distribution system with narrowing nozzles located symmetrically relative to longitudinal axis of tower, sprinkler and the pool, divided into sections by partitions, each of which is made of bimetal in a zigzag manner with formation in the section of alternating staggered confusers and diffusers, and the water distribution system is arranged in pairs located convergent nozzles and on the inner surface of each of the pair of nozzles, curved grooves are arranged longitudinally from a larger base to a smaller one, while in the first of a pair of nozzles, the curved groove guide has a direction clockwise, and in the second curvilinear groove guide is directed against the clockwise movement, wherein the exhaust tower is equipped with a fan located in its upper part, a fan drive rotation speed controller and a temperature controller with an ambient air temperature sensor, wherein the temperature controller by its output is connected to the rotation speed controller in the form of a powder electromagnetic couplings unit, and the temperature controller comprises a comparison unit and a setting unit, wherein the comparison unit is connected to the input of the electronic amplifier, equipped with the nonlinear feedback unit, and the output of the electronic amplifier is connected to the input of the magnetic amplifier with a rectifier, which is connected at the input to the rotation speed controller, in addition, the exhaust tower from the outer surface is coated with thin-fibre basalt material, arranged in the form of twisted bundles, longitudinally extended from below upwards, wherein the coating with thin-fibre basalt material in the form of twisted beams on the outer surface of the exhaust cooling tower is made with sets, where the bundles in pairs with the number of at least four are arranged in the form of sinusoids, longitudinally elongated in height, protrusions and recesses of which when aligned are concentrators of moving seismic waves, and areas of maximum convergence of sinusoids make nodes that facilitate formation of standing waves. There is a thermoelectric generator including a housing with a channel for hot water and a set of differential thermocouples, the "hot" ends of which are located inside the channel for hot water, and the "cold" ends are fixed on the outer surface of the thermoelectric generator housing, wherein the "hot" and "cold" ends of the differential thermocouples are coated with a dielectric from the epoxide enamel, besides, inlet of hot water channel of thermoelectric generator housing is connected to supply manifold of water distribution system, and its outlet is connected to water distributor.EFFECT: providing fire-safe operation of a fan cooling tower by eliminating a wire network for feeding a system for automated operation of a fan.1 cl, 6 dwg
