Grooved Fin Tube or ‘G’ Finned Tube (Embedded Fin Tube) for Fin Fan Cooler

Grooved fin tube or ‘G’ Finned Tube (Embedded Fin Tube) is a heat exchange element that features grooves cut into the outer surface of a base tube and then embedded with fins. It is primarily used to enhance heat exchange efficiency. The core process involves machining spiral or straight grooves in the outer surface of the base tube, then inserting and securing the fins within the grooves.

Grooved Fin Tube or ‘G’ Finned Tube (Embedded Fin Tube) Process Features

Spiral Grooving: Spiral grooves of a specific width and depth are machined into the base tube surface, ensuring that the fins are not easily removed once inserted.

Embedded Structure: The fins fit tightly against the outer surface of the base tube, increasing the heat transfer area while reducing thermal resistance.

Material Compatibility: The base tube can be made of carbon steel, stainless steel, copper, or aluminum. The fins are typically made of aluminum or copper, with a temperature resistance of up to 400°C.

Grooved Fin Tube or ‘G’ Finned Tube (Embedded Fin Tube) Applications

Industrial Heat Exchange Equipment: Suitable for air coolers, chillers, economizers, and other equipment, particularly in the chemical and petrochemical industries where demand is high.

Innovative Design: Datang has improved installation methods through technology, enhancing maintenance convenience.

The primary purpose of using embedded fin tubes in air coolers is to increase the heat transfer area and improve heat dissipation efficiency.

1. Expanded Heat Transfer Area

Finned tubes significantly increase the surface area of ​​the base tube by adding metal fins (such as spiral or wavy shapes) to the outer wall of the tube. As air flows through the fins, heat is more efficiently transferred from the tube wall to the air. This design can quickly reduce the temperature of the medium, especially in high-temperature industrial applications (such as natural gas compressors and chemical production). ‌

2. Improved Heat Dissipation Efficiency

The fin structure increases the contact area between air and the tube wall, accelerating heat exchange. For example, spiral fin tubes utilize a spiral winding method to further increase the contact area, allowing heat to dissipate more quickly. This design is widely used in the power generation, chemical, and other fields, effectively ensuring stable equipment operation. ‌

3. Adaptable to Industrial Needs

Modern industrial cooling scenarios demand high efficiency. Embedded Fin Tubes utilize embedded technology and alloy materials (such as corrosion-resistant stainless steel and aluminum) to maintain stability under extreme temperatures and pressures, extending equipment life.

Grooved Fin Tube or 'G' Finned Tube Appearance Dimension Inspection

Grooved fin tube or ‘G’ finned tube appearance dimension inspection‌ is one of the important links to ensure the quality and performance of fin tubes.

The inspection items mainly include fin height, fin spacing, fin thickness, base tube wall thickness and outer diameter, etc.

Grooved Fin Tube or 'G' Finned Tube (Embedded Fin Tube) Bending Processing

‌Bending of fin tubes‌ is an important step in the production process of grooved fin tube or ‘g’ finned tube (embedded fin tube). Bending is to bend the embedded fin tube material through specific mechanical equipment to form a suitable curvature to meet different usage requirements.

This step requires strict control of the bending angle and curvature to ensure the fit between the fin and the base tube and the heat dissipation effect‌.

Grooved Fin Tube or 'G' Finned Tube (Embedded Fin Tube) Pull Off Test

Grooved fin tube or ‘g’ finned tube (embedded fin tube) pull-off test ‌ is a test used to detect whether the fin tube will fall off when subjected to tension, mainly used to ensure the quality and reliability of the fin tube.

Datang’s this test is very important in the production process because the g type finned tubes will be subjected to various stresses during operation, such as temperature changes and pipe expansion, which may cause the fin to fall off, thereby affecting the performance and safety of the heat exchanger ‌.
