What is the difference between an air-cooled tower and a liquid-cooled tower

Air cooling towers and liquid cooling towers are two different types of cooling equipment, and there are some significant differences between them. Here’s a comparison and summary of the two:

How it works:

Air cooling tower: It mainly uses the flow of air to make the heat in the water be taken away by the air through the contact between water and air, so as to achieve the cooling effect. Specifically, hot water flows from the top of the tower and is distributed on the packing to form a water film, and the air comes into contact with the water film through the cooling tower, taking away the heat in the water, and the cooled water is discharged from the bottom of the tower.
Liquid cooled towers: While the exact principle of operation may vary depending on the design and application, it typically involves the use of a liquid coolant to absorb heat and transfer it to the outside environment in some way, such as a heat exchanger.

Cooling medium

Air cooling tower: Mainly uses air as the cooling medium, and cooling is achieved through direct contact between air and water.
Liquid cooled towers: Liquid coolants, such as specific coolants or water, are used to absorb and transfer heat.


Air cooling towers: widely used in power plants, petrochemical, pharmaceutical, metallurgical and other fields, for cooling hot water or hot fluids in various industrial equipment.
Liquid-cooled towers: They are often used in applications that require more efficient and precise temperature control, such as high-performance computing centers, data centers, etc., because these occasions have strict requirements for the operating temperature of the equipment.
Efficiency and Effectiveness:
Air Cooling Towers: High efficiency and suitable for large-scale heat dissipation, but affected by ambient temperature and humidity.
Liquid cooled towers: typically provide more stable and efficient cooling because liquid coolants typically have a larger specific heat capacity and are better able to absorb and transfer heat.

Cost & Maintenance

Air-cooled towers: typically have low initial investment and operating costs, and are relatively simple to maintain.
Liquid-cooled towers: Higher initial investment and operating costs may be required due to the use of special liquid coolants and more complex maintenance procedures may be required to ensure the proper functioning of the system.
In summary, there are clear differences between air-cooled and liquid-cooled towers in terms of operating principle, cooling medium, field of application, efficiency and effectiveness, as well as cost and maintenance. The type of cooling tower you choose depends on your specific application needs and scenarios.
