Closed circuit cooling tower (also known as evaporative air cooler or closed cooling tower) is the tubular heat exchanger placed in the tower, through the circulation of air, spray water and circulating water heat exchange to ensure cooling effect. Closed circuit cooling tower is widely used in iron and steel metallurgy, power electronics, machining, air conditioning system and other industries.
a. The cooling tower is a counter flow and cross flow cooling tower based on the design idea of forced circulation. The closed counter flow cooling tower covers a small area, has a compact structure, and can be combined with many sets, so the cooling effect is better.
b. The closed counter flow cooling tower belongs to mechanical refrigeration, which avoids a series of problems that the thermal cycle of the open cooling tower is directly connected with the atmosphere, and the circulating medium is easy to be polluted; the closed counter flow cooling tower uses cold water to cool the medium in the coil directly so that the cooling medium has no pollution, less damage, remarkable energy saving effect and good environmental protection effect.
c. The wind tube of closed counter flow cooling tower adopts aerodynamic design. This kind of curve structure greatly reduces the water drift rate of cooling tower.
d. The closed counter flow cooling tower adopts coil type structure, and the copper tube or stainless steel tube has more sufficient heating surface and higher heat exchange efficiency.
e. The closed counter flow cooling tower is divided into counter flow heat transfer and cross flow heat transfer. The counter flow heat transfer can control the temperature of cooling medium below normal temperature.
f. With its superior structural design, the closed counter flow cooling tower can completely operate under low pressure, and can directly cool high-temperature media such as hydraulic oil, alcohol and quenching liquid. The stainless steel or galvanized aluminum shell not only has beautiful appearance but also has longer service life.
Compared with the cross flow tower, the closed counter flow cooling tower of our company has more compact structure, more coil heat dissipation area, and can be arbitrarily combined to meet the requirements of various water quantity and temperature difference. It is suitable for conventional refrigeration projects.
