What is Air Cooled Fin Fan Heat Exchanger?
An Air Cooled Fin Fan Heat Exchanger uses ambient air as the cooling medium to cool or condense high-temperature fluid within a tube. It requires no water, is suitable for high-temperature and high-pressure processes, has a long service life, and offers low operating costs. It is widely used in industries such as petrochemicals, coal chemical industry, power plants, and metallurgy.
With increasing water and energy scarcity and growing environmental awareness, the water-saving, energy-saving, and pollution-free Air Cooled Fin Fan Heat Exchanger is expected to gain widespread application.
★Induced Draft Unit:
The tube bundle is located below the fan. Because the air duct effectively shields the tube bundle from dust, wind, rain, and snow, the induced draft air cooler offers stable heat exchange performance. It also features uniform air volume distribution, minimal heat circulation, minimal fouling, and low noise.
★Forced Draft Unit:
The tube bundle is located on the exhaust side of the fan. This design facilitates maintenance and ensures the fan motor is always in a cooler air environment, extending its lifespan.
★A-Type Air Cooler:
The tube bundle of the A-Type air cooler is positioned at a 60-degree angle at the top of the frame, resulting in a compact footprint. It is primarily used for condensing media. Its internal tube resistance and film heat release coefficient are better than those of horizontal air coolers.
★Two-Step Air Cooler:
Air cooling is performed first, followed by evaporative cooling. The motor is not affected by hot air, resulting in a long lifespan. This maximizes the effectiveness of the air cooling stage and significantly saves water. The organic combination of air cooler and evaporative air cooler can save water and meet more application occasions. (When the medium outlet is close to the ambient temperature)
Application of Air-Cooled Fin Fan Heat Exchanger
Compared to traditional industrial cooling systems using water as the cooling medium, the advantages of the Air-Cooled Fin Fan Heat Exchanger are shown in the following table:
Air Cooling
1. No thermal or chemical pollution to the environment.
2. Air is readily available, requiring no additional equipment or costs. Site selection is unrestricted, which is particularly important in areas with no or limited water supply. 3. Air is less corrosive, requiring no descaling or cleaning, and has a long service life.
4. The air pressure drop is only 98-196 Pa, so air cooling has low operating costs.
5. Maintenance costs for air cooling systems are generally only 20%-30% of those for water cooling systems.
6. Once the fan power is cut off, 30%-40% of natural cooling capacity remains.
Water Cooling
1. Discharge water poses thermal and often chemical pollution risks to the environment.
2. Cooling water is often limited by water sources, requiring the installation of pipelines and pumping stations. For larger plants, especially, sufficient water sources must be considered when selecting a site.
3. Water is highly corrosive and prone to scaling, requiring treatment.
4. The circulating water pressure head is high, resulting in higher energy consumption for water cooling.
5. Due to the large number of water-cooled equipment, scaling is prone to occur. In warm climates, microorganisms can easily form and attach to cooler surfaces, requiring frequent shutdowns for cleaning.
6. A power outage forces all production to cease.
