Closed cooling tower is the tube heat exchanger placed in the tower
Closed Cooling tower (also known as Evaporative air cooler orClosed Cooling Tower) is to place the tubular heat exchanger in the tower, through the circulation of air, sprinkler water and circulating water heat exchange to ensure the cooling effect. Because it is a closed cycle, it can ensure that the water quality is not polluted, very good protection of the efficient operation of the main equipment, improve the service life. When the outside temperature is low, you can stop the sprinkler system and play a water-saving effect. With the implementation of national energy saving and emission reduction policies and the increasing scarcity of water resources, closed cooling towers have been widely used in iron and steel metallurgy, power electronics, machining, air conditioning systems and other industries in recent years.
According to the direction of water flow and wind direction can be divided into: countercurrent closed cooling tower, cross-flow closed cooling tower.
According to the shell material can be divided into: galvanized steel plate closed cooling tower, aluminum-galvanized plate closed cooling tower, stainless steel closed cooling tower, FRP closed cooling tower and so on.
According to the heat exchanger material can be divided into: Copper tube closed cooling tower, stainless steel pipe closed cooling tower, carbon steel pipe closed cooling tower, titanium tube closed cooling tower, aluminum tube closed cooling tower and so on.
According to the type of fan can be divided into: wind-type closed cooling tower, blast type closed cooling tower.
