What is an Aluminum Bi-metallic Finned Tube?

Aluminum Bi-metallic Finned Tube is a heat exchange element made by combining two different metal materials through rolling technology. It is primarily used to enhance heat transfer efficiency and adapt to complex industrial environments.

Aluminum Bi-metallic Finned Tube Structure

It consists of a base tube (such as alloy steel or stainless steel) and fins (such as aluminum or copper). The fins are rolled out using a fin tube extrusion machine to ensure thermal conductivity and structural strength. The base tube transports the heat medium (such as steam or hot water), while the fins increase the heat dissipation area.

Steel-aluminum bimetallic finned tubes are finned tubes made by combining steel and aluminum through precision processing. They are typically cold-rolled to tightly fit the aluminum tube (base tube) onto the steel tube, and then fine-roll the fins onto the aluminum tube surface, creating a tightly bonded composite structure. This design not only combines the high strength of steel with the excellent thermal conductivity of aluminum, but also significantly improves heat exchange efficiency.

Bi-metallic aluminum finned tubes increase surface area through the fins, while aluminum enhances heat transfer efficiency, resulting in heat transfer efficiency more than ten times that of standard steel or stainless steel finned tubes. Furthermore, due to the compressive strength of steel and the excellent heat transfer properties of aluminum, these steel-aluminum composite finned tubes are highly sought after.

Features of Aluminum Bi-metallic Finned Tubes:

-Excellent Thermal Conductivity: Aluminum’s high thermal conductivity enables bi-metallic aluminum finned tubes to quickly and efficiently transfer heat during heat exchange, improving heat exchange efficiency.

-Strong Corrosion Resistance: Aluminum easily forms a dense oxide film on its surface, effectively resisting corrosion and extending its service life.

-High Pressure Capacity: The high strength of steel provides the finned tubes with excellent pressure bearing capacity, enabling them to withstand high operating pressures.

-Large Heat Dissipation Area: The fin structure significantly increases the heat dissipation area and improves heat dissipation efficiency, making them suitable for a variety of heat exchange equipment.

-Long Service Life: The tight connection and corrosion resistance ensure that bi-metallic aluminum finned tubes maintain stable performance over long periods of use, reducing maintenance costs.

Advantages of Aluminum Bi-metallic Finned Tube

High-Efficiency Heat Dissipation: The large-diameter design and fin structure improve heat transfer efficiency, making it suitable for heat exchange systems in industrial equipment.

Corrosion Resistance: The bimetallic combination withstands high temperatures, high pressures, and corrosive environments, extending service life.

Multi-Heat Media Compatibility: It supports high-temperature steam, hot water, or special heat transfer media, making it suitable for applications in the chemical, power, and metallurgical industries.

Applications of Aluminum Bi-metallic Finned Tube

It is widely used in heating systems, industrial cooling equipment, and waste heat recovery systems, particularly in applications requiring high heat dissipation efficiency and structural stability.

Steel-aluminum bi-metallic finned tubes are widely used in workshops, factories, greenhouses, and industrial plants, as well as in residential heating systems. They play a key role in heat exchange equipment such as air coolers, condensers, evaporators, and heaters, providing efficient and reliable heat exchange solutions for industrial production.
