Cooling tower components and parts

As you know, a cooling tower is used to cool the circulating water in air conditioning systems or industrial processes. Cooling towers are produced and used in various shapes and dimensions and have different components and parts, each of which has a specific role in the system's performance. The components and parts of the cooling tower include the body, electric motor, fan, fan stack, louver, gearbox, sprinkler, nozzle, basin, packing, floater, drip catcher, etc., which we will describe below. Stay with us.

Cooling tower skeleton

The skeleton or structure is the main framework of the cooling tower, which is responsible for maintaining the static resistance of the device, as well as protecting the components and circulating water in the system. The skeleton of the cooling tower is generally made of hot galvanized steel and is resistant to high humidity and adverse weather conditions.

Cooling tower electric motor

The electric motor supplies the energy needed to rotate the cooling tower fan. Since this part is placed outside, it must be protected from harmful environmental conditions such as sunlight and cooling tower humidity.
The power transmission system in electric motors is direct (direct drive) and indirect (belt), which is usually used in large cooling towers of indirect or belt type.

Cooling tower gearbox

The gearbox is responsible for controlling the torque of the electric motor and transferring it to the cooling tower fan.

Cooling tower nozzle

The nozzle or sprinkler is used in the cubic-type cooling tower and is responsible for spraying the incoming water from the top of the tower on the packings. Nozzles are used in different types and shapes, but they are generally divided into gravity and spraying categories according to their mechanism.

Eliminator of the cooling tower

The Eliminator is one of the components of the cooling tower that prevents water drops from leaving the top of the tower and directs them downwards, thereby preventing water loss in this section. Eliminators have two types of honeycomb and blade and are usually made of PP, and PVC materials.

The sprinkler of the cooling tower

The sprinkler or water dispenser of the cooling tower actually does the job of the nozzle and is responsible for spraying water on the packings, with the difference that the water spraying is done in a circular way and is used in circular cooling towers. The water dispenser of the cooling tower consists of two fixed parts (Stator) and a rotating (Rotor) and is made of aluminum, brass, cast iron, stainless steel, etc.

Cooling tower packing

The water sprayed by the nozzle spreads over the packings or the cooling surfaces of the cooling tower. This work increases the contact surface of the airflow with water, thus increasing the heat transfer between water and air. The packings are made of PP and PVC and fall into two general groups: splash and film (waterfall), each of which has different types. Splash packings have a lower heat exchange surface than film packings, but they are less exposed to sediments and have easier descaling.

Cooling tower fan

The fan or propeller is one of the main components of the cooling tower, which circulates it in the tower by sucking air from outside. Fans are available in two types, axial and centrifugal, and the axial type is generally used in cooling towers. Fans should be resistant to stress and long-term operation, and at the same time, they should be light in weight to move with a less driving force. Normally, in fiberglass towers, fans are made of fiberglass, steel, aluminum, or plastic.

Fan stack of cooling tower

Fan stack or fan ring refers to the chimney part like the cooling tower, which is placed in the upper part of the device. The fan stack with its structure improves the airflow coming out of the cooling tower and protects its internal components such as the fan, motor, gearbox, etc.

Louver of cooling tower

The louver is actually the air inlet valve in the lower part of the cooling tower body, which is produced with a shutter or honeycomb structure and made of PVC, PP, and fiberglass. With the rotation of the fan, fresh air is directed to the tower through these louvers. The presence of louvers in the cooling tower prevents sunlight from entering inside and prevents the growth of algae. In addition, the louver prevents the entry of solid materials (such as leaves) into the fan and pan of the cooling tower.

Cooling tower basin

The cold water basin is one of the most important components of the cooling tower, which is responsible for collecting cold water and storing it in the lower part of the cooling tower. The existence of a pan is very important in industries with extensive production and requiring a large volume of water.

Cooling tower floater

The float controls the water level in the basin (cold water pool). A floater is a plastic ball floating on the water, which moves with the change of water level and causes the compensatory water flow to be interrupted and connected.

Cooling tower heater

In industrial projects where the cooling tower operates all year round, a heater or the same element is used to prevent it from freezing in the winter season.

Cooling tower control equipment

In the cooling tower, in order to control parameters such as temperature, level, flow, etc., some instruments are used, such as the inverter system to change the fan speed, compensating water flow meter, pan level control switch, temperature sensor, vibration meter, etc.
