Embedded Finned Tube ASTM A179 with AL1060 Fins For Air Coolers and Condensers
An Embedded Finned Tube ASTM A179 with Aluminum 1060 Fins is a specialized heat exchanger component designed to enhance heat transfer efficiency. It consists of a base tube made of ASTM A179 carbon steel and fins made of Aluminum 1060, which are embedded into the tube's surface. This combination leverages the strengths of both materials to provide high thermal performance, durability, and corrosion resistance.
Key Components:
1. Base Tube (ASTM A179):
Material: Low-carbon steel.
Properties: High thermal conductivity, excellent mechanical strength, and good pressure resistance.
Applications: Suitable for high-temperature and high-pressure environments.
2. Fins (Aluminum 1060):
Material: Pure aluminum alloy (99.6% aluminum).
Properties: High thermal conductivity, lightweight, excellent corrosion resistance, and good formability.
Applications: Ideal for enhancing heat transfer in air or gas environments.
3. Embedded Fin Design:
The fins are mechanically embedded into the outer surface of the tube, creating a strong bond between the tube and fins.
This design ensures efficient heat transfer from the tube to the fins and then to the surrounding medium (e.g., air or gas).
The base tube carries the primary fluid (liquid or gas) that needs to be heated or cooled.
The aluminum fins increase the surface area of the tube, allowing for more effective heat exchange with the secondary medium (usually air or gas).
Heat is transferred from the tube to the fins and then dissipated into the surrounding environment.
Key Features:
- High Thermal Efficiency: The combination of carbon steel and aluminum maximizes heat transfer rates.
- Corrosion Resistance: Aluminum fins provide excellent resistance to corrosion, especially in moist or chemically aggressive environments.
- Lightweight: Aluminum fins reduce the overall weight of the heat exchanger.
- Durable: The embedded fin design ensures a strong mechanical bond, preventing fin loosening over time.
- Cost-Effective: Offers a balance between performance and cost compared to all-aluminum or all-copper finned tubes.
