1. Product Description 

SHBN counter-flow closed cooling tower is a collection of  many years of experience in the design and manufacture of large-scale cooling tower, set the latest technology in the cooling tower industry at home and abroad as a whole; by using tower components with excellent performance, with its excellent quality, widely used in metallurgical, chemical, electric power, pharmaceutical and other industries in the circulating cold water system .

2. Operation principle

The basic operation principle of SHBN counter-flow closed cooling tower is as follows：

The hot medium passes through the inner part of the heat exchange coil and spreads the heat to the external air and spray water. After being cooled, it flows out from the lower coil outlet；

The cooling medium flows inside the coil pipe without any contact with the outside world, which can guarantee the clean state of the medium to meet the good working state of the system with strict requirements；

The external circulating water from the bottom of the equipment is sprayed to the outer surface of the coil by the special low-head large-flow pump through the upper water distribution system, ensuring full coverage, enhancing heat transfer and effectively controlling the possibility of scale formation；

The lower part of the unit is surrounded by an air inlet, and the fresh air from the outside enters the equipment. After the surface of the coil pipe, a part of sprinkled water is gasified. The latent heat of water gasification is very large, which can effectively exchange the heat inside the coil and eventually exhaust through the fan.
