What Are The Types Of Cooling Towers?

Cooling towers can be classified according to a variety of different standards. Here are some common classification methods:
1. Classification by ventilation method
A natural ventilation cooling tower is a cooling tower that works by using the air convection mechanism generated by natural wind or the difference in air density inside and outside the tower to achieve ventilation. The design of this cooling tower is very simple, does not generate noise and power consumption, but its heat dissipation effect is not ideal, especially suitable for small heat dissipation environments.
A mechanical ventilation cooling tower, also often referred to as a forced ventilation cooling tower, is a fan-driven cooling device. Its core function is to provide the necessary heat dissipation function for water through forced ventilation. This cooling tower has excellent heat dissipation effect, especially suitable for large-scale heat dissipation tasks, but it is relatively more significant in noise and energy consumption.
A hybrid ventilation cooling tower successfully combines the advantages of natural ventilation and forced ventilation, achieving a perfect fusion of the advantages of both.
A side-outlet cooling tower represents a unique cooling tower design concept, and the air outlet direction is blown from the side.
2. Classification based on the contact mode between hot water and air
The core function of a wet cooling tower is to dissipate heat through the evaporation of water. This technology is not only efficient and low-noise, but also does not pollute the environment, but it also requires a lot of water resources.
Dry cooling towers use air to dissipate heat for water. This method does not consume water resources or pollute the environment, but its heat dissipation effect is not very ideal, especially suitable for heat dissipation applications of small cooling towers.
Dry-wet cooling towers successfully combine the technical characteristics of wet cooling and dry cooling, and give full play to the unique advantages of these two technologies.
3. Classification according to the flow direction of hot water and air
The significant feature of counterflow cooling towers is that the flow directions of hot water and air are exactly opposite. This cooling tower is extremely sophisticated in design, has a low wind volume, and its cooling efficiency is very outstanding.
Crossflow cooling towers, also often referred to as direct-current cooling towers, work in the following way: hot water flows vertically from above, while air flows horizontally and flows through specific filling materials. This cooling tower is characterized by its energy saving, low water pressure and low wind resistance, and the maintenance of its filling materials and water distribution system is also very simple and convenient.
Mixed flow cooling towers successfully combine the two unique flow modes of counterflow and crossflow, while also retaining the advantages and strengths of each of these two modes.
4. Classification based on morphological characteristics
A circular cooling tower is a specially designed cooling tower whose main purpose is to be used in large industrial cooling systems.
A square cooling tower, also known as a rectangular cooling tower, is a cooling tower designed in a square or rectangular shape, which is particularly suitable for cooling systems of different sizes.
5. Classification based on various application scenarios
The core function of an industrial cooling tower is to achieve heat dissipation in the industrial manufacturing process.
The core function of an air-conditioning cooling tower is to provide the necessary heat dissipation capacity for an air-conditioning system.
The core responsibility of a mechanical cooling tower is to provide heat dissipation services for various mechanical equipment.
The cooling tower in an injection molding machine is a structure specially designed for the heat dissipation needs of an injection molding machine.
6. Classification based on the degree of noise
Ordinary cooling towers have a relatively high noise level, which makes them particularly suitable for application scenarios where noise standards are not particularly strict.
The notable feature of a low-noise cooling tower is its relatively low noise level, which makes it particularly suitable for environments with special noise requirements.
The noise level of ultra-low noise cooling towers is relatively low, which makes them particularly suitable for applications with strict noise requirements.
The noise level of ultra-quiet cooling towers is extremely low and almost no noise is generated, which makes them particularly suitable for specific environments with extremely high noise requirements.
VII. Classification by materials used
FRP cooling towers, also known as FRP cooling towers, are made of FRP materials, which have many advantages such as corrosion resistance, light weight and high strength.
Cooling towers made of galvanized steel use galvanized steel as the main material. This cooling tower has many significant advantages such as corrosion resistance, high strength and long service life.
Stainless steel cooling towers made of stainless steel have excellent corrosion resistance and high strength, which makes them very suitable for operation in harsh environments.
Item 8, other types of classification
Based on whether the circulating water is in direct contact with the air, we can divide cooling towers into closed cooling towers (also known as closed cooling towers) and open cooling towers.
According to the established design standards, we can divide them into cold ton type (wet bulb temperature reaches 27°C) and water ton type (wet bulb temperature is 28°C).
According to the cooling effect of hot water, we can classify it into three types: ordinary type (37℃-32℃), medium temperature type (43℃-33℃) and high temperature type (65℃-35℃).
According to various combinations, cooling towers can be divided into two types: single fan cooling tower and multi-fan combination cooling tower.
In addition to these, there are many special cooling tower designs such as jet cooling tower, fanless cooling tower and hyperbolic cooling tower. In the selection process of this special type of cooling tower, the use environment, heat dissipation requirements, surrounding environmental conditions and budget costs are usually considered comprehensively.
