A cooling tower is a partially enclosed apparatus used to evaporatively cool water by coming into touch with air. For more even distribution and improved atomization of the water inside the tower, corrugated surfaces, baffles, or perforated trays are placed inside the wooden, steel, or concrete construction. The top of the tower is fed with hot water from the condenser, which is then let to tease in tiny drops. After being effectively cooled, the air exits from the bottom of the tower or in a direction opposite to the water flow. At the top of the tower, draft eliminators are supplied to stop water particles from escaping into the air. Read More…
Cooling Tower DesignCooling tower design is an integral part of the overall design and layout of a processing plant or large building. Cost-effectiveness and energy and performance efficiency are all reliant on how well a particular cooling tower is suited to an application for heat removal.

At Cold Shot Chillers, we create a number of chilling systems, including cooling towers. Our products are designed for durability and cost effectiveness. Our engineers can easily custom build any machine to fit the needs of a particular application.
Fill, also known as a wet deck or surface, broadens the cooling tower's surface area to maximize the air and water's surface contact and contact time with the least amount of airflow obstruction.
The distribution system depends on the cooling tower type according to the air-to-water flow. Cross-flow cooling towers distribute water at a height above the fill— utilizing a gravity-flow distribution mechanism.
By abruptly altering the direction of the air stream, drift eliminators stop water droplets from evaporating. As a result, large water droplets hit the walls of the drift eliminator as the air stream passes, forcing the water to fall.
The Driveshaft, Fan, Motor, and Speed Reducer
Depending on the sort of draft required for the application, the fans force air into or out of the cooling tower. The motor is the primary driver. The driveshaft transmits the motor's torque to the fan or a gearbox. Large cooling towers with large, big fans need gearboxes to enhance torque, which reduces the need for powerful motors and, in turn, the requirement for a more robust frame. Gearboxes are occasionally used in place of belt and pulley assemblies.
The cooling tower includes air intake louvers as a barrier against water splash-out, noise, and debris. They are a typical component of cross-flow cooling towers and are positioned around the tower, below the panel where the fill is packed, and above the cold water basin.
The casing's roles are to transmit loads to the tower frame and act as housing. It also helps keep water inside the cooling tower contained.
Types of Cooling Towers
Cooling towers come in various designs better suited for specific uses and functions. Some of these are open-loop towers, closed-loop towers, evaporative cooling, counter-flow, and cross-flow systems. For design considerations, it is important to remember that water cooling towers often use less energy than air cooling systems. One of these types, or a mixture, would work best for heat removal, depending on the area, cool water sources, electrical supply, and available material resources. Below are the different types of cooling towers.
Natural Draft Cooling Towers
In natural draft cooling towers, the airflow through the cooling tower is created without mechanical drivers or fans. The difference in ambient air densities below and above the cooling tower is used to its advantage. Denser air near the tower's base moves to a place with lower pressure above the tower, causing air to flow. Although these towers are cheap, they can only be put outside. Additionally, these towers are less reliable because the ambient wind and temperature variations impact them more.
Mechanical Draft Cooling Towers
These towers generate airflow through the tower using one or more fans. Since airflow can be adjusted following the necessary cooling load, mechanical draft cooling towers are more dependable and stable than natural draft cooling towers. Forced or induced draft cooling towers are another mechanical draft cooling towers category.
This cooling tower uses fans or blowers, as the name implies, to force air into the cooling tower. As the blower forces the airflow, it has a high entrance velocity. As a result, airflow slows as it travels through the tower. In addition, recirculation causes performance to be less steady than with induced draft towers. When high static pressure is a concern indoors, forced draft cooling towers are used.
These towers have fans at the top which pull (or force) air into the tower through air intake louvers at the bottom or sides. This configuration has a low entrance and a high exit velocity, which leads to less recirculation than forced draft cooling towers. These cooling tower designs are frequently employed in industrial plants that demand reliable performance.
Uses of Cooling Towers
Steam is the working fluid used in power-producing facilities. First, coal, natural gas, or even nuclear radiation are used to heat water to steam which, in turn, produces electricity. Then, this heat is changed into mechanical energy. Some heat must be evacuated to finish the steam cycle because it cannot be turned into energy. In this situation, cooling towers are useful.
Industrial Plants (Oil and Gas, Petrochemicals)
Industrial plants remind one of a power plant. Process heat is absorbed via condensers, heat exchangers, and cooling jackets. Water then carries this heat and rejects it through the cooling tower.
Heating, Ventilation, and Air Conditioning (HVAC)
Residential and business spaces need HVAC for comfortable cooling. The cooling system absorbs the heat produced by people, machinery (such as computers and servers), lighting, solar radiation, and outdoor ambient air before rejecting it to the cooling tower.
Refrigeration is for pharmaceuticals, air and gas generation, cold storage in the food and beverage industries, etc. This process is comparable to an HVAC system, where a refrigerating unit rejects heat to a cooling tower after absorbing heat from a closed environment.
Choosing the Proper Cooling Tower Design Company
To make sure you have the most beneficial outcome when purchasing Cooling Tower Design from a Cooling Tower Design Supplier, it is important to compare at least 4 or 5 Companies using our Cooling Tower Design directory. Each Cooling Tower Design Company has a business profile page that highlights their areas of experience and capabilities and a contact form to directly communicate with the manufacturer for more information or request a quote. Review each Cooling Tower Design company website using our patented website previewer to get an idea of what each business specializes in, and then use our simple RFQ form to contact multiple Cooling Tower Design companies with the same form.
