Abstract: A cooling tower comprises a body provided with air-intake windows located above a catch basin, and a water distributor, which has a sprinkler, and an irrigators. Ring tubular units are connected to each other to form a ring-type evaporator fed from a pipeline, which is used for water supply from a water source independent of the water distributor, and are vertically arranged in the apertures of the air-intake windows. Equally spaced atomizing sprayers are mounted on each of the tubular units along the circumference of the unit. The invention makes it possible to enhance the operational performance of the cooling tower in a hot environment by improving operating service and maintenance conditions.
