Finned Aluminum Tubing for Heat Exchanger

What are finned aluminum tubes for heat exchangers?

Finned aluminum tubes for heat exchangers are components that utilize metal fins attached to an aluminum base tube to enhance heat transfer, primarily used to improve heat exchange efficiency.

Structure and Function of Finned Aluminum Tubes for Heat Exchangers

Aluminum finned tubes consist of an aluminum base tube and metal fins, achieving efficient heat transfer by increasing the heat transfer surface area. The fins are typically attached to the outside of the base tube, creating a dense heat dissipation surface suitable for high-temperature, high-pressure, or corrosive environments.

Applications of Finned Aluminum Tubes for Heat Exchangers

Industrial Applications: Used for high-temperature heat transfer in boilers, power equipment, metallurgy, and other applications.

Refrigeration Equipment: Used in air conditioner condensers and evaporators to improve cooling efficiency.

Building Air Conditioning: Used as a heat exchange element to regulate indoor air temperature. ‌

Advantages of Aluminum Fin Tubes for Heat Exchangers

Aluminum offers high thermal conductivity (approximately 0.502 W/(m·K)) and corrosion resistance, reducing thermal resistance and extending service life. New structures, such as split fins and narrow-to-wide variable-width channels, can improve heat transfer efficiency by 20%-40%.
