The main components of a crossflow closed cooling tower includes upper and lower boxes, panels, spray water devices, cooling coils, material heat exchange layer, cooling filling, drift eliminator, bottom water collection tank, axial flow fan, circulating water pump, and electronic water treatment instrument (optional).

There is another name for a closed cooling tower: evaporative condenser, sometimes abbreviated as evaporative cooling. Some people also refer to it as an air cooler, but it is still different from an air cooler. An air cooler is a cooler that only cools with ain
and does not have spray water.

Closed cooling towers are mainly used for cooling and refrigeration of industrial circulating media, with over 80% being used for circulating water cooling; ln chemical engineering, it is mainly used for phase change cooling of refrigerants, such as changing from ammonia gas phase to ammonium water, and from the gaseous state to liquid state of fluorides; Other oil and alcohol liquids are also cooled do own, such as hydraulic oil, quenching fluid, ethylene glycol, and other chemical liquids.
Inside the closed cooling tower, there is a heat exchange tube bundle. Through water spraying, air circulation, and water circulation inside the tower, heat exchange is achieved, thereby achieving the purpose of cooling or cooling. The internal circulation medium does not come into contact with the external environment throughout the entire process, thus greatly ensuring water quality, and avoiding medium evaporation. and prolonging the service life of the cooling tower, Moreover, when the external temperature is relatively low, the spraying system can be suspended, which can also reduce the waste of water sources.
