What is an air cooled heat exchanger?
An air cooled heat exchanger, also known as an air cooler,fin fan cooler is a cooling device that uses air to cool process fluids within pipes. It has largely replaced traditional water coolers.
Air cooled heat exchangers are an indispensable component of cooling systems in refineries and petrochemical plants. Their applications range from tower overhead oil and gas condensation to gasoline and diesel cooling. They are also widely used in the chemical, power, metallurgical, and nuclear energy industries.
Basic components of an air cooler:
1. One or more finned tube bundles, through which the fluid to be cooled or condensed passes, while air flows outside the tubes to cool the fluid.
2. One or more axial fans, which drive the air flow.
3. Frame.
4. Accessories, such as louvers, steam coils, ladders, and rooftops.
Tube Bundle
The tube bundle consists of finned tubes, a tube box, and a frame. The ends of the tubes are expansion-jointed to the sides of the tube box. The upper and lower sides of the tubes are connected to the inlet and outlet pipes. The tubes are arranged in a triangular pattern and can be installed horizontally, inclined, or vertically.
Air Cooled Heat Exchanger Material
L type finned tube air cooled heat exchanger uses L type finned tubes, the maximum allowable medium temperature is ≤150℃.
LL type finned tube air coolers use LL type finned tubes, with a maximum allowable medium temperature of 170°C.
G type finned tube air cooled heat exchanger uses G type finned tubes, with a maximum allowable medium temperature of 350°C.
KLM finned tube fan fin coolers use KLM finned tubes, with a maximum allowable medium temperature of 250°C.
Bimetallic finned tube air cooled heat exchanger uses extruded rolled finned tubes, with a maximum medium temperature of 280°C.
Serrated finned tube air cooled heat exchangers use serrated finned tubes,their heat transfer performance is 25% higher than of high frequency welded fin tubes.
Forced draft fin fan cooler tube bundles are placed horizontally.To prevent condensate from accumulating in the tubes, the tubes should be tilted 3° or 1%.
Plug type air cooled heat exchanger can be used for gasoline, kerosene and other light oils and solvents,the pressure form is ≤20MPa.
Air Cooled Heat Exchangers By Industy
Air-cooled heat exchangers are widely used in industries such as chemical, environmental protection, power generation, petroleum, and pharmaceuticals. They cool or condense high-temperature process fluids, conserving water, reducing water pollution, and offering low investment and maintenance costs. Air coolers are particularly suitable for water-scarce regions, effectively alleviating water shortages.
Air-cooled heat exchangers in the chemical industry: Cool reaction products and circulating gases.
Air-cooled heat exchangers in the petroleum and petrochemical industries: Condensate oil and gas and handle high-temperature fluids.
Air-cooled heat exchangers in the power generation industry: Dissipate heat from boilers and mechanical equipment.
Air-cooled heat exchangers for drying industries: Participate in heat exchange processes within the process.
Air Cooled Heat Exchanger Water Pressure Test
An air cooler water pressure test uses water as the medium. Water is injected into the equipment and pressurized to test the equipment’s sealing and pressure-bearing capacity.
Pressure testing is crucial for the safe operation of air coolers. It allows for the timely identification and resolution of equipment problems, such as leaky seals and insufficient pressure-bearing capacity. Failure to identify and address these issues can lead to equipment failures and even accidents. Therefore, pressure testing is not only a test of equipment performance but also a safeguard for industrial safety.
Induced Draft Air Cooler and Forced Draft Air Cooler
Applicable Applications and Features: Suitable for all applications. The tube bundle is placed horizontally, with a 3° or 1% inclination to prevent condensate from accumulating in the tubes.
Advantages: Simple structure, easy installation, and relatively uniform distribution of hot fluid within the tubes and air outside.
Disadvantages: Requires a larger footprint, and greater flow resistance within the tubes than with inclined top tubes.
Air Cooled Heat Exchanger Air Pressure Test
An air pressure test on an air cooler uses gas as the medium. Pressure testing tests equipment performance by applying pressure. Strictly following operating procedures ensures the safety and reliability of the process and results.
Pressure testing is essential after equipment installation or maintenance. It helps verify the equipment’s sealing and pressure-bearing capacity, ensuring that safety incidents such as leaks or ruptures do not occur during operation.
Nondestructive Magnetic Particle Testing of Air Coolers
Nondestructive magnetic particle inspection of air coolers uses magnetic particles as a detection medium to observe defects in air coolers.
Magnetic particle inspection has a sensitivity that can detect discontinuities as narrow as 0.1μm. By combining multiple magnetization methods, magnetic particle inspection is virtually unaffected by workpiece size and geometry, and can detect defects in all directions.

High Frequency Welded Spiral Fin Tube Application
The spiral fin tube radiator for vegetable and flower greenhouse is an efficient and durable heating equipment, especially suitable for greenhouse cultivation in cold seasons.
During the breeding and brooding process, the high-frequency welded fin tube radiator improves the heat exchange efficiency by increasing the heat dissipation area, and can raise the temperature in the brooding house to the required level in a short time. This design enables the farm to quickly reach and maintain a suitable temperature range (15-20 degrees Celsius) when heating in winter.
Hot-dip galvanized spiral wound fin tube for greenhouse heating, as a key component of the heating system, can efficiently and evenly transfer heat to keep the temperature in the greenhouse within a suitable range
As a high-efficiency heat exchange element in modern industrial and civil heating systems, the unique design of the helical tension wound finned tube radiator for steam heating not only significantly improves the heat transfer efficiency, but also optimizes the space utilization rate, becoming an indispensable thermal energy source in many fields. equipment.
The working principle of the crimped fin tube is based on the principles of heat conduction and convection. When the hot water or steam of the heating system flows through the finned tube, the heat is quickly transferred to the heat sink through the fins and then dissipated into the air. This design makes the heat exchange more efficient and is particularly suitable for workshop environments that require a lot of heat dissipation.
