Technical Field

[0001] The utility model relates to the field of spraying devices, in particular to a closed cooling tower with a double spraying pump system. Background Art

[0002] A closed cooling tower, also known as a sealed cooling tower, is an efficient heat exchange device. The working principle of the closed cooling tower is based on the dual cooling methods of heat conduction and evaporation heat absorption. Cooling is achieved through the heat exchange of air, spraying water and circulating water. The closed cooling tower adopts a closed cycle, and the cooling medium does not directly contact the outside air, so it can prevent water quality from being polluted, protect the efficient operation of the main equipment and improve the service life. Closed cooling towers are widely used in various fields such as metal melting equipment, large motors, and cooling of industrial solutions.
