** Dry-Wet Combined Air-Cooled Tower Technical Analysis and Application Research**

In industrial production processes, the efficiency and environmental friendliness of cooling systems directly affect the energy consumption and operating costs of enterprises. The dry-wet combined air-cooled tower, as a new type of cooling equipment that combines the advantages of dry and wet cooling, has attracted widespread attention in the industrial cooling field in recent years. This article will delve into the working principle, structural features, core advantages, and applications in various industries of the dry-wet combined air-cooled tower, aiming to provide reference for technological research and application in related fields.

### 1. Dry-Wet Combined Air-Cooled Tower Working Principle and Structural Features

Dry-Wet Combined Air-Cooled Tower Mainly composed of dry and wet sections, supplemented by shared components such as fans, water pumps, and control systems. The dry section uses finned tube heat exchangers to achieve cooling through indirect heat exchange (sensible heat exchange) between air and circulating water inside the tubes. The wet section uses spray water directly contacting air, reducing temperature through evaporative cooling (latent heat exchange).

In terms of operating modes, Dry-Wet Combined Air-Cooled Tower it has flexible operation strategies. Under high temperature or high load, the wet and dry sections can operate jointly to maximize heat dissipation efficiency; under low temperature or low load, time-sharing switching can be used to operate only the dry section to reduce water consumption. Additionally, water can be pre-cooled by the dry section before entering the wet section (series operation), or the two sections can operate independently (parallel operation) to meet different cooling demands.

### 2. Dry-Wet Combined Air-Cooled Tower Core Advantages

The dry-wet combined air-cooled tower integrates the advantages of both dry and wet cooling systems, achieving a balance between water saving and efficient heat dissipation. Compared to pure wet towers, its water saving rate can reach 30%~70%, making it especially suitable for water-scarce areas or projects with strict environmental requirements. In terms of water saving, the dry section operates efficiently in low-temperature environments, while the wet section compensates for heat dissipation at high temperatures, ensuring stable performance throughout the year. The wet section can be shut down in winter to avoid spray water freezing; meanwhile, the dry section reduces the emission of humid hot air, effectively suppressing white fog phenomena.

Intelligent control is another highlight of the dry-wet combined air-cooled tower. The intelligent control system can dynamically adjust operating modes based on parameters such as temperature, humidity, and load to optimize energy efficiency. The application of AI algorithms enables the equipment to optimize operation strategies in real time, dynamically balancing water and energy consumption, further enhancing energy-saving effects.

In addition, Dry-Wet Combined Air-Cooled Tower it also adopts multiple new technologies and materials. The application of hydrophilic coatings, corrosion-resistant alloys, and other new materials improves heat exchange efficiency and equipment lifespan. Zero-emission design combined with water recycling systems achieves the reuse of cooling water, reducing environmental impact.

### 3. Application Research of Dry-Wet Combined Air-Cooled Tower

With its high efficiency and water-saving characteristics, the dry-wet combined air-cooled tower has been widely applied in various industrial fields. In the power industry, it is especially suitable for use in arid areas at sites requiring circulating water cooling such as thermal power plants and nuclear power stations, effectively reducing water resource consumption. In the data center field, the equipment can meet the demand for stable heat dissipation throughout the year while emphasizing sustainability, providing strong support for the green operation of data centers.

The chemical and metallurgical industries are also important application areas for the dry-wet combined air-cooled tower. During high-heat process cooling, the equipment can balance heat dissipation needs and water-saving goals, achieving efficient and environmentally friendly cooling effects. Additionally, in power-rich areas such as wind, hydro, tidal, and nuclear energy, the dry operation of the dry-wet combined air-cooled tower requires large air volume and high fan motor power, which can fully utilize the electricity in these regions, further reducing operating costs.

### 4. Technical Challenges and Future Prospects of Dry-Wet Combined Air-Cooled Tower

Although the dry-wet combined air-cooled tower has many advantages, it still faces some technical challenges in practical applications. For example, precise control of the switching logic between dry and wet sections is required to avoid efficiency loss caused by frequent start-stop cycles. The wet section needs anti-scaling and anti-biofouling measures, while the finned tubes in the dry section require regular cleaning to ensure heat exchange efficiency. Moreover, CFD simulation should be used during design to optimize airflow distribution and avoid mutual interference between dry and wet sections.

Looking ahead, as the industrial cooling field demands higher efficiency, water saving, and environmental protection, the dry-wet combined air-cooled tower will have broader development prospects. Through continuous technological innovation and optimization, the equipment is expected to achieve application breakthroughs in more fields, contributing to the green transformation of industrial production. At the same time, strengthening equipment maintenance and management to ensure long-term stable operation is also key to the future promotion and application of dry-wet combined air-cooled tower technology.
