Base Tube Material: ASTM A179 Carbon Steel
ASTM A179 is a seamless carbon steel tube known for its excellent mechanical properties and heat transfer capabilities. It is commonly used in heat exchangers, air coolers, and condensers where durability and effective heat transfer are critical. The carbon steel provides strength and is ideal for industrial applications under moderate to high-temperature conditions.
Fin Material: Aluminum Strip
Aluminum is an ideal fin material due to its excellent thermal conductivity, corrosion resistance, and light weight. The aluminum strip used for the fins increases the surface area for heat exchange, improving the overall efficiency of heat transfer in air cooler systems. Additionally, aluminum provides long-lasting performance even in harsh environmental conditions.
Fin Type: Spiral Embedded Fin
The spiral embedded fin design involves winding the aluminum strip in a spiral around the base tube. This design significantly enhances the heat transfer area while creating turbulence in the fluid flow, improving heat exchange efficiency. The embedded design ensures a strong, secure bond between the tube and the fins, preventing fin detachment over time.
Application: Designed for air cooler systems, this fin tube is ideal for applications that require efficient heat dissipation, such as cooling fluid or air in industrial processes, HVAC systems, and power plants.

Enhanced Heat Transfer: The spiral embedded fin design significantly increases the surface area, improving the heat transfer performance. The spiral winding also generates turbulence, which reduces the boundary layer and boosts the thermal efficiency of the air cooler system.
Corrosion Resistance: The aluminum fins are resistant to oxidation, ensuring long-lasting performance even in humid or corrosive environments typically found in air cooler applications.
Durability: ASTM A179 Carbon Steel provides the necessary strength to withstand mechanical stresses and high pressure in industrial cooling systems. The embedded fins provide strong mechanical bonding, reducing the risk of fin detachment over time.
Cost-Effective: The combination of carbon steel for the base tube and aluminum for the fins offers a cost-effective solution while still maintaining excellent heat transfer and corrosion resistance.
Versatile Design: The spiral embedded fin design is highly customizable in terms of fin height, thickness, and the number of fins per inch, enabling optimization for various cooling requirements.
