Closed Cooling Tower

A closed cooling tower is a cooling device that combines a cooling tower and a shell-and-tube water cooler. The main principle is to use the evaporation of the water film outside the tube to enhance the heat transfer outside the tube. The process water in the tube flows through the coil tube bundle, and heat is transferred to the outside air through the heat transfer of the partition wall and the evaporation of the spray water outside the tube, so as to reduce the temperature of the process water in the tube, without contact with the atmosphere and pollution. In water-restricted areas and process equipment with high water quality requirements, the use of closed cooling towers and closed circulating water systems can effectively reduce the water consumption of enterprises, protect the main process equipment, and extend the maintenance cycle.

A closed cooling tower is a heat exchange device for cooling liquids and is widely used in industrial cooling. Its main feature is to isolate the working fluid from the external environment through a closed heat exchanger (usually a coil or pipe), thereby reducing the evaporation, pollution and scaling of water. Compared with open cooling towers, closed cooling towers can provide more stable cooling effects, and are more water-saving and environmentally friendly. It is widely used in induction heating and metal smelting equipment, various reactors and condensers in the chemical industry, cooling of large equipment, cooling of molds, etc.

Advantages and Disadvantages

Advantages

Good water-saving effect: Since the working liquid circulates in a closed pipe, the closed cooling tower greatly reduces the evaporation of water and the need for replenishing water.
Avoid water pollution: The closed system of the closed cooling tower avoids direct contact between the coolant and the external environment, reduces the impact of external pollutants on the coolant, and reduces the risk of scaling.
Low maintenance cost: The closed design reduces the occurrence of common problems such as scaling, algae and corrosion, thereby reducing maintenance frequency and repair costs.
Flexible installation: The closed cooling tower can be flexibly designed as a vertical or horizontal structure according to site requirements, occupies less space, and is suitable for various occasions.

Disadvantages

Higher initial investment cost: The closed structure and complex spray system of closed cooling towers make them more expensive to manufacture, so the initial purchase cost is higher than that of open cooling towers.
Relatively low cooling efficiency: Compared with open cooling towers, closed cooling towers have slightly lower heat exchange efficiency, especially in dry mode, where the cooling effect is limited by the ambient temperature.
High maintenance requirements: Although the closed system reduces water pollution problems, it is still necessary to regularly check the operation of the heat exchanger and spray system to ensure that the equipment works properly for a long time.
