Fin Fan Cooler

A Fin Fan Cooler, also known as an Air Cooled Heat Exchanger (ACHE), is a mechanical device used to cool fluids usually oil, gas, water, or chemicals by using ambient air as the cooling medium. It’s essential for industrial cooling systems where water is scarce or restricted due to environmental regulations. The name "Fin Fan Cooler" comes from two key components:

• Fins: Extended surfaces that increase the heat transfer surface area.
• Fans: Large axial or centrifugal fans that blow air over the finned tubes to remove heat.

They are widely used in refineries, petrochemical plants, power generation, fertilizer, and gas processing industries.

Environmental Benefits:

• No water usage = eco-friendly.
• No water treatment or disposal required.

Operational Benefits:

• Low maintenance compared to water-cooled systems.
• Modular design for easy expansion and customization.
• Ideal for remote or desert locations.

1. Hot Fluid Flow: The process fluid enters the cooler through header boxes and flows through a bundle of tubes.
2. Finned Tubes: Tubes with extended fins (usually aluminum or copper) increase heat transfer efficiency.
3. Ambient Air: Fans blow air across the fins to extract heat from the fluid.
4. Cool Fluid Exit: The cooled fluid exits and is returned to the process line.

• Tube Bundle: The heat exchange core, typically made of carbon steel, stainless steel, or copper alloys.
• Fins: Spiral-wound or extruded metal fins bonded to tubes for enhanced heat transfer.
• Fan Assembly: Axial fans powered by electric motors or gearboxes; mounted above or below.
• Plenum Chamber: Distributes air evenly across the tube bundle.
• Header Boxes: Channels fluid into tubes; available in plug, bonnet, or cover plate types.
• Support Structure: Holds the assembly, designed to handle wind, vibration, and dynamic loads.

• Forced Draft: Fans below the tubes push air upward. Ideal for clean environments.
• Induced Draft: Fans above the tubes pull air through, reducing recirculation.
• Natural Draft: No fans; uses chimney effect. Least efficient but most eco-friendly.
