High-Efficiency Industrial Cooling: Datang Finned Tube Dry Air Cooler
Product Overview
The Dry Air Cooler (also known as an Air-Cooled Heat Exchanger) manufactured by Datang Finned Tube is a sustainable industrial cooling solution designed to dissipate heat from process fluids into the ambient air. As a high-performance cooler heat exchanger, it offers a closed-loop system that cools water, glycol, or oils without any water consumption, making it the premier choice for eco-conscious and water-scarce environments.
By integrating advanced dry cooler heat exchanger technology, our units serve as a reliable alternative to traditional cooling towers, eliminating the risks of scaling, contamination, and plume.
What is a Dry Cooler?
Working Principle
Our dry air cooler operates on the principle of forced convection. The hot process fluid circulates inside the high-quality tubes of the air cooler exchanger. Simultaneously, large-volume axial fans draw cooler ambient air across the external finned surface. Through the precision-engineered surfaces provided by Datang Finned Tube, heat is transferred efficiently from the fluid to the air, ensuring optimal discharge temperatures.
Dry Air Cooler Core Components and Operation
The system consists of three primary elements: a finned tube heat exchanger, motorized fans, and a supporting structure.
-
Finned Tubes: The hot process fluid (such as water, glycol, or oil) flows through a series of tubes. These tubes are equipped with external “fins” which significantly increase the surface area available for heat transfer.
-
Air Induction: Large axial fans pull or push ambient air across the exterior of the finned tubes.
-
Heat Exchange: Heat is transferred from the fluid inside the tubes, through the tube wall and fins, and into the passing air. The cooled fluid then returns to the process cycle.
Dry Cooler Heat Exchanger Common Configurations
Dry coolers are typically designed in two main orientations depending on space and efficiency requirements:
-
Horizontal / Flatbed: These units lie flat and are common for smaller applications or where roof space is abundant but height is restricted.
-
V-Type: The heat exchanger coils are arranged in a “V” shape. This footprint is more compact and allows for higher airflow and cooling capacity within a smaller ground area.

Dry Air Cooler Key Advantages
-
Zero Water Consumption: Because it is a closed-loop system, there is no water loss through evaporation or drift.
-
Low Maintenance: Without a water circuit, there is no risk of scaling, legionella growth, or the need for complex chemical water treatments.
-
Environmental Impact: They eliminate the need for water disposal and do not create a visible “plume” of steam.
-
Reliability in Cold Climates: Using a water-glycol mix prevents freezing, which is a common issue with traditional open cooling towers.
Dry Cooler Heat Exchanger Typical Applications
Dry air coolers are widely used in industrial and commercial sectors, including:
-
Power Plants: For cooling turbine steam or jacket water in engines.
-
Data Centers: To manage heat from servers via water-cooled racks.
-
Oil & Gas: Cooling crude oil or gas streams during processing.
-
HVAC Systems: Acting as condensers for large-scale refrigeration or air conditioning units.

In the construction of an Air Cooled Heat Exchanger, the tube bundle acts as the core heat transfer unit, while the finned tubes serve as the fundamental heat exchange elements within that bundle.Common Types:Wrap-on L/LL-Fin,G-Fin / Grooved,Extruded Fin,HFW Fin.Material Combinations:Base Tube SA179/SA106,Fin:Aluminum
-
In the design and operation of Air Cooled Heat Exchangers (ACHE),the fan is the power core of an air-cooled system, responsible for forcing ambient air through the tube bundles to achieve thermal exchange for process fluids.Core Components:Blades,Hub and Fan Ring/Shroud. It compensates for the low density of ambient air by forcing convection.

Air Cooled Heat Exchanger (ACHE) Plugs and GasketsIn the structure of an Air Cooled Heat Exchanger (ACHE), the plug is a small but critical pressure-retaining component. It is installed on the plug header, positioned directly opposite the opening of each individual finned tube.Plug materials:Carbon Steel,Stainless Steel and Alloy Steel.Fin Fan Cooler Plugs are often used in conjunction with gaskets.
Dry Air Cooler Water Pressure Test
An dry 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.
Dry Cooler Heat Exchanger Air Pressure Test
An air pressure test on an dry cooler heat exchanger 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 Dry Cooler Heat Exchangers
Nondestructive magnetic particle inspection of dry cooler heat exchangers 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.

Dry Cooler Heat Exchanger 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.
