The invention relates to heat exchangers, in particular, cooling towers, and can be used to cool water in a circulating water supply system.

The purpose of the invention is to increase the efficiency of heat and mass transfer.

The drawing shows the fan of the cooling tower torn;

The torn valve of the cooling tower contains a housing 1 with air inlets 2, a catchment pool 3. In case 1, a water trap 4 is installed, a sprinkler made from at least Two steps 5 and 6 arranged by the batons. Under the upper stage 5, there is an additional water distributor 10 connected by pipelines 9 to the main water distributor 7. N. Pipelines 9. ejectors 11 are installed, receiving chambers of which are in communication with the atmosphere. Sprinklers 12 additional water distributor 10 is directed to the upper stage 5 irrigation. Case 1 contains a confuser 13, a diffuser 14. A fan 15 is installed in the throat of the diffuser 14.

The water to be cooled is supplied to the water dispensers 7 and 10.

With sprinklers 8 and 12, the water irrigates the upper stage 5 of the irrigator and flows, interacting with the flow of the upward air, to the lower stage 6 of the irrigator and further into the basin 3,
