FIELD: cooling towers and systems of water recirculation of industrial enterprises. ^ SUBSTANCE: the invention is pertaining to the method of cooling a temperature of water in the heat-exchange aggregates, for example, in cooling towers and may be used in the systems of water recirculation of industrial enterprises. The method of cooling a temperature of water in the heat-exchange aggregates provides for the action by airflows on an evaporated surface of water. At that the surface of water in addition is exposed to a high-frequency ultrasonic action using the frequencies corresponding or multiple to the frequencies of the natural thermal oscillations of molecules of water: VA = Vnto.n and VA = Vnto /n, where: VA - frequency of acoustic oscillations; Vnto - frequency of natural thermal oscillations: where: i - average number of the intermolecular spacing intervals passed by a molecule or a particle till their concussion; L - a distance between the centers of molecules; d - a diameter of a molecule; k - Boltzmann constant; T-thermodynamic temperature of water; m - a molecular (corpuscle) mass; n - an integer 1,2,3,4,5, etc., at that with an amplitude of an oscillation displacement of the acoustic waves, equal or exceeding the value of the intermolecular spacing interval, at which the forces of attraction between the molecules of the water are insignificantly small: A >= l, where: A - is an amplitude of an oscillation displacement of the acoustic waves; l - a spacing interval between molecules of water, at which forces of attraction between them are insignificantly small: l ≈ 10-9 m. The high-frequency acoustic action on the evaporated surface is conducted simultaneously in two mutually intersecting directions. At that one of the directions is tangential to the evaporated surface. The high-frequency acoustic action on the evaporated surface is conducted mainly in the direction of motion of the aerodynamic airflows of the cooling tower. The evaporated surface is exposed to the high-frequency acoustic action frontally with an intensity level >= 145 dB, and tangentially - with a level of intensity >= 120 dB. The invention allows to raise intensity of cooling of water. ^ EFFECT: the invention ensures an increase of intensity of cooling of water. ^ 4 cl, 3 dwg |
