Seamless steel-aluminum extruded finned tubes are a precise combination of seamless steel tube bodies and aluminum alloy fins. Through the extrusion process, low resistance and efficient heat transfer are achieved. With a large heat dissipation area, strong temperature uniformity, and the ability to withstand high-temperature, high-pressure, and corrosive environments, they ensure stable and efficient heat exchange in industrial cooling, power equipment, HVAC systems, and other scenarios. They have become a core component driving energy-saving upgrades in the industry.

The base tube is made of seamless steel, whose seamless process ensures uniform tube walls, free from welding defects, and provides excellent mechanical strength and pressure-bearing capacity. When facing high-temperature, high-pressure heat media, it can operate stably, effectively avoiding leakage risks, and ensuring the safety and stability of the heat exchange system. Meanwhile, the good thermal conductivity of the steel tube lays a foundation for the initial heat transfer, ensuring that the heat carried by the heat media can be quickly transferred to the surface of the base tube.

The fins are made of aluminum alloy, which has excellent thermal conductivity, enabling rapid absorption of heat from the base tube and efficient dissipation of heat into the surrounding environment. The extrusion process forms a strong, low-resistance connection between the fins and the base tube, with a smooth heat transfer path and minimal thermal resistance. The fins are regularly arranged and tightly wrapped around the base tube surface, significantly increasing the heat dissipation area. Their shape, spacing, and other parameters are carefully designed to optimize the flow path of air or other media between the fins, promoting convective heat exchange and improving overall heat transfer efficiency.

1. Seamless steel tubes must undergo strict selection and pre-treatment to ensure material purity and smooth tube walls, providing a good foundation for the subsequent extrusion process.
2. The quality of aluminum alloy materials must also be guaranteed, with their composition and properties meeting specific standards.
3. During the extrusion process, precise control of temperature, pressure, speed, and other parameters is required to uniformly extrude the aluminum alloy onto the surface of the seamless steel tube, forming a closely fitting fin structure. This process demands high equipment precision and operational skills. Only by precisely controlling each link can high-quality seamless steel-aluminum extruded finned tubes be produced.

Its strong heat dissipation capability, large fin area, and efficient heat transfer path enable it to quickly dissipate the heat of the heat media and achieve significant temperature changes in a short time, meeting various scenarios that require rapid heat exchange. For example, in industrial cooling systems, it can quickly reduce the temperature of high-temperature media to ensure the normal operation of production equipment.

The regularly arranged fins and stable heat transfer process ensure that heat is evenly dissipated in all directions, avoiding local overheating or underheating, and providing a stable heat exchange environment for processes that require precise temperature control.

In industries with strict requirements for temperature uniformity, such as the heat dissipation process in electronic chip manufacturing, seamless steel-aluminum extruded finned tubes can ensure consistent temperatures across different parts of the chip, improving chip performance and stability. In terms of durability, the high strength of seamless steel combined with the corrosion resistance of aluminum alloy fins enables the finned tubes to adapt to complex and harsh working environments. Whether in high-temperature, high-humidity, or corrosive media environments, they can operate stably over the long term, reducing equipment failures and maintenance frequency, lowering usage costs, and extending equipment life.
