Air Cooler Heat Exchanger API 661 For Power Generation Plants ISO 13706
Industrial air coolers heat exchanger, also known as forced-draft air coolers (FDAC) or evaporative coolers, they are widely used in large-scale projects requiring efficient, cost-effective heat dissipation.
Some Common Key Projects
Industrial air coolers heat exchnager typically occurs in the following types of projects:
Power Generation Plants, Focus: High-temperature resistance, corrosion protection (for coastal plants,ect.)
Thermal Power Plants
1.Direct Air-Cooled Condensers (ACC) ,for steam turbine exhaust cooling (replacing water-cooled condensers).
2.Auxiliary Cooling for pumps, compressors, and transformers.
Gas Turbine Power Plants
1.Inlet Air Cooling, increases efficiency by lowering intake air temperature.
Nuclear & Renewable Energy Plants
1.Waste Heat Rejection, used in dry cooling systems for solar thermal or nuclear plants.
Oil & Gas / Petrochemical Industry, Key Requirements:Explosion-proof design (ATEX certification), chemical-resistant materials (e.g., stainless steel 316L)
Refineries
1.Cooling for distillation columns, reactors, and heat exchangers.
Chemical Plants (Ethylene, Fertilizers, etc.)
1.Process cooling for compressors and reactors.
LNG Terminals
1.Cooling boil-off gas (BOG) recondensation systems.
Metallurgy & Heavy Manufacturing, Key Technical Requirements:Dust-proof filters, high-temperature fan systems (>150°C)
Steel Mills
1.Blast furnace cooling, continuous casting machine cooling.
Aluminum & Copper Smelting
1.Electrolytic cell cooling, flue gas heat recovery.
Cement Plants
1.Rotary kiln and grate cooler cooling.
An air cooler is a euipment that cools air through the evaporation of water. Their advantage is that unlike traditional air conditioners that use refrigerants and compressors, air coolers are more energy-efficient and environmentally friendly. They work best in hot, dry climates where humidity is low.
Key Advantages
Energy Efficiency: fans consume less power than water-cooled systems.
Low Maintenance: unlike cooling towers,no need water treatment.
Dry Operation: ideal for water-scarce regions.
Modular Design: easy to scale for large industrial loads.
Air Cooler Heat Exchanger Works
The core components: finned tubes(embedded G finned tubes or extruded finned tubes,etc.); forced-draft fans; header/manifold; support structure (steel frame to withstand wind or loads).
Note about finned tubes: Aluminum fins for corrosion resistance, stainless steel for harsh chemicals.
Working Principle
1. Hot Process Fluid Enters: The fluid (water, oil, steam, or chemicals,ect.) flows through the tubes.
2. Forced-Draft Fans Blow Air: Fans actively push ambient air across the finned tube.
3. Heat Exchange Occurs: Air absorbs heat from the tubes via conduction/convection.Fins amplify surface area for faster cooling.
4. Cooled Fluid Exits: The process fluid leaves at a lower temperature, ready for reuse.
5. Hot Air Discharged: Warm exhaust air is released to the atmosphere.
