1. Working principle:

High-efficiency composite air cooler combines the dual advantages of dry air cooling and evaporative cooling:

1. Dry cooling stage: The high-temperature medium first passes through the air-cooled fin tube bundle, uses air convection to dissipate heat, and initially cool down.

2. Evaporation cooling stage: The residual heat forms a water film on the surface of the evaporation tube bundle by spraying water, and further cools the medium by using the latent evaporation heat of water.

3. Intelligent control: Real-time monitoring of temperature through sensors, automatic switching of dry/wet operating modes, and optimize energy consumption and cooling efficiency.

2. Core advantages:

1. Energy-saving and water-saving

· Compared with traditional water-cooling systems, water savings are as high as 90% (no water is required during dry operation), and the overall energy consumption is reduced by 20%-70%.

· Closed circulation design avoids water quality pollution, reduces the demand for descaling and sewage discharge, and reduces maintenance costs.

2. Efficient heat dissipation

·Using a modular combination design (such as combining finned tube bundles and evaporative tube bundles), the heat transfer coefficient is increased by 10%-15%, and the cooling efficiency is equivalent to that of a water-cooled and air-cooled series system.

·High thermal conductivity materials (such as aluminum-magnesium alloy fins, stainless steel tube bundles) and uniform water distribution technology to ensure high heat flow density.

3. Environmental adaptability

·Supports dry and wet mixed operation, adapt to extreme climates (such as -40°C to 50°C), and solves the problem of cooling in water-scarce areas or severe cold environments.

·Dust and anti-freeze design (such as electric heat tracing systems) extend the service life of the equipment and meet the needs of high corrosion scenarios such as chemical industry and metallurgy.

4. Intelligent and low maintenance

·Integrated AI temperature control algorithm, temperature difference control accuracy reaches ±1C, and supports frequency converter fan speed regulation and remote fault warning.

·The modular structure supports online maintenance. The failure of a single module does not affect the overall operation, and the downtime is reduced by 60%.
