2. Apa itu Spiral Fin Tube Heat Exchanger

Manufacturers build a spiral fin tube heat exchanger using tubes wrapped tightly with continuous helical fins. The spiral fins increase the surface area on the outside, thereby increasing heat transfer between the gas and liquid. This compact exchanger is used when high thermal efficiency and low operating costs are required. Spiral fin tube heat exchangers are used in air-cooled, gas-cooling, and exhaust heat-recovery applications.

3. How Spiral Fin Tubes Improve Heat Transfer

The spiral fins increase the contact surface area and thus the heat exchange. First, the fin forces the air to flow across a longer distance. Next, the increased turbulence improves thermal efficiency. The spiral structure strengthens the mechanical bond between the fin and tube, helping the heat exchanger maintain consistent transfer efficiency even in harsh environments.

4. Main Characteristics of Spiral Fin Tube Heat Exchanger

The spiral fin tube heat exchanger has the following structural characteristics and performance characteristics:

• Continuous helical fin enlarges the heat transfer surface area.
• Robust mechanical lock enhances heat conduction effect.
• Compact structure with a small installation footprint.
• High heat transfer coefficient saves operating power.
• Uniform airflow distribution improves heat transfer performance.
• Anti-vibration design prolongs service life.
• Adjustable fin height and thickness to suit customer needs.

In addition, the heat exchanger also has the characteristics of supporting high-temperature gas media and corrosive media by using different materials and upgrading processes.

5. Spiral Fin Tube Types

Different types of spiral fin tubes support different applications:

5.1 L-Type Spiral Finned Tube

The fin base is wrapped around the tube and takes the form of an “L”. It has the advantages of low price and is used in ordinary cooling.

5.2 LL-Type Spiral Finned Tube

The fin base is wrapped around the tube and overlaps. This design can enhance the corrosion resistance and strength of the fin.

5.3 KL-Type Spiral Finned Tube

The fin base is embedded on the tube surface. The connection is more reliable and can work at a higher temperature.

5.4 G-Type Embedded Spiral Fin Tube

The fin is inserted into the machined groove. It has the most robust mechanical lock and the best thermal performance.

Therefore, different types of spiral fin tubes can be selected according to the temperature of the gas medium, the degree of corrosion, and the thermal performance required by the user.

6. Construction and Materials

Komponen utama dari sebuah spiral fin tube heat exchanger adalah sebagai berikut:

• Base tube (carbon steel, stainless steel, alloy steel)
• Spiral fins (aluminum, copper, stainless steel)
• Tube headers
• Frame and supports
• Air-cooled fans (optional)
• Anti-vibration brackets

The choice of materials is related to temperature, corrosion, and fluid medium conditions. Stainless steel spiral fins have high corrosion resistance, while aluminum spiral fins are lightweight and thermally efficient.

7. Advantages of Spiral Fin Tube Heat Exchangers

The spiral fin tube heat exchanger has the following benefits:

• High heat transfer efficiency due to increased surface area.
• Compact structure, ideal for limited space installation.
• Stable operation in high-temperature gas environments.
