What are air-cooled heat exchangers?
Air-Cooled Heat Exchangers (ACHEs) are a type of mechanical unit that rely on ambient air to cool process fluids. Using finned tubes and high-performance fans, these systems dissipate heat from the process fluid into the atmosphere, providing a highly efficient and cost-effective cooling solution. The process fluid flows through tube bundles, while air is drawn over the surface of the tubes, transferring heat from the fluid to the air. This method eliminates the need for water, making it a clean energy solution for industries looking to conserve resources and avoid the additional costs associated with water-cooled systems.
At ICARUS, our Air-Cooled Heat Exchangers are engineered for maximum heat transfer efficiency, ensuring reliable operation in various operating conditions such as high ambient temperatures, fluctuating atmospheric pressures, and high-velocity air flows. These exchangers offer a dependable solution for industries that require efficient cooling for high heat loads and consistent performance in challenging environments.
Applications of air cooled heat exchangers
Air cooled heat exchangers are versatile and used across a broad range of industries. Below are some key applications:
• Power generation: In power plants, air coolers are used to cool turbines, generators, and other high-temperature equipment, helping maintain safe operating conditions and reduce exhaust temperatures. Their ability to handle high rates of air flow makes them ideal for cooling in electric utility applications.
• Chemical processing plants: Used to cool down process fluids, air-cooled heat exchangers help control process outlet temperatures and ensure efficient operation in chemical plants. They are ideal for handling high pressures and maintaining performance in harsh environments, with correction factors applied to optimize performance under varying conditions.

Aftercoolers and jacket water coolers are also integral to this process, maintaining ideal fluid inlet temperatures.
• Refineries and oil coolers: These exchangers are employed in refineries to manage high heat transfer demands, cooling various fluids, including jacket water and lubricating oils, in large-scale industrial systems. Our exchangers handle hot process fluid flows effectively, ensuring reliable operation.
• Industrial cooling: In general industrial applications, these exchangers can be used to cool machinery, electric motors, and other process equipment, making them essential components in industries ranging from natural gas to wind energy. Their adaptability to a wide range of ambient conditions makes them a preferred choice for various cooling needs.
Types of air cooled heat exchangers
ICARUS offers a wide range of Air-Cooled Heat Exchanger designs, each optimized for specific industrial needs:
1. Finned Tube Air-Cooled Heat Exchangers:
These exchangers use finned tubes to maximize the surface area for heat transfer between the process fluid and the air. This design is commonly used in power plants and chemical industries, where efficient cooling is required under high heat loads and demanding conditions. The convection heat transfer coefficient is carefully optimized to ensure predictable and consistent performance.
2. Forced Draft and Induced Draft Air-Cooled Heat Exchangers:
Forced draft systems push air through the finned tubes using high-performance fans, while induced draft systems pull air across the heat exchanger tubes. Each design offers specific advantages depending on the application, with forced draft units often being more efficient in power generation and gas compression.
3. Natural Draft Air-Cooled Heat Exchangers:
Utilizing natural air currents to dissipate heat, these units require no external fan power, making them an energy-efficient option in ambient conditions where natural airflow is sufficient. These systems often serve as part of dry cooling towers in electric utility and industrial cooling applications.
4. Compact Heat Exchangers:
Designed for applications with limited space, our compact heat exchangers offer high thermal performance in a lightweight and small footprint design, ideal for industrial cooling and machinery that operates in confined environments, such as box-type or machinery mount installations.

FAQ about air cooled heat exchangers
What are the key advantages of using finned tube air-cooled heat exchangers?
Finned tube heat exchangers maximize the heat transfer surface by increasing the contact area between the air and the fluid flowing through the tubes. This leads to more efficient actual heat transfer, making them ideal for applications where high performance is critical, such as in natural gas industries and power plants.
How do pressure drop characteristics affect the performance of air-cooled heat exchangers?
Pressure drop characteristics refer to the resistance the air or fluid encounters as it flows through the exchanger. Minimizing the pressure drop is crucial for maintaining efficient air flow and ensuring that the system operates within its designed velocity range, optimizing overall performance.
What are the different types of heat exchangers available for industrial use?
There are various types of heat exchangers, including finned tube exchangers and counter flow heat exchangers. Each is suited to different applications, with air-cooled exchangers being a popular choice for direct cooling and low-maintenance operation in a range of industrial settings.
How does air-side heat transfer coefficient impact heat exchanger efficiency?
The air-side heat transfer coefficient measures the effectiveness of the heat transfer between the air and the finned tubes. A higher coefficient results in more efficient convection heat transfer, leading to faster cooling or heating of the heat transfer fluid and better overall performance of the exchanger.
What are the installation requirements for air-cooled heat exchangers?
Installation of an air-cooled heat exchanger typically involves mounting the unit on pipe racks or other support structures, ensuring proper air distribution and minimizing hot air recirculation. Adequate spacing is needed to allow for fan coverage and airflow, and considerations such as elevation above grade and cross beams should be factored into the design.
How does dry bulb temperature affect the performance of air-cooled heat exchangers?
The dry bulb temperature of the surrounding air is a key factor in the cooling efficiency of an air-cooled unit. The lower the ambient air temperature, the more effective the exchanger will be at cooling the process fluid, as there is a greater temperature difference for the actual heat transfer process to occur.
What is the role of headers in air-cooled heat exchangers?
Headers in air-cooled heat exchangers distribute the process fluid evenly through the tube bundles, ensuring uniform flow through bundles and maintaining predictable heat transfer across the entire exchanger. Proper header configurations can significantly improve the system’s efficiency by reducing flow imbalances.
What industries benefit from air-cooled heat exchangers, and what are typical applications?
Air-cooled heat exchangers are widely used in industries like natural gas processing, power generation, and chemical processing. Common applications include cooling aftercoolers on compressors, jacket water coolers, and glycol coolers, where efficient heat dissipation is critical for maintaining system reliability.
How do fan performance characteristics impact the efficiency of air-cooled heat exchangers?
The fan performance curve shows how fan speed, diameter, and fan tip speed affect airflow and cooling efficiency. Ensuring reasonable fan power consumption and adjusting the pitch or speed reducer can help optimize airflow, reducing energy use while maintaining adequate cooling.
What factors contribute to the total cost of air-cooled heat exchangers?
The costing of heat exchangers is influenced by factors like the raw materials used (e.g., steel fins or aluminum), fan horsepower requirements, and the complexity of the design condition. Additional costs may arise from installation, maintenance, and any necessary adjustments to handle varying ambient conditions and process fluid temperatures.
