The working principle of extruded fin tubes is based on its unique structure and manufacturing process, which achieves effective heat transfer by increasing the heat transfer area and improving the heat conduction efficiency. Extruded finned tubes have the advantages of simple structure, easy manufacturing and installation, so they are widely used in industries such as electricity, petrochemicals and refrigeration.
Extruded finned tubes are a high-efficiency heat transfer element, which is widely used in various heat exchange equipment, such as heat exchangers, radiators, condensers, etc.
The characteristics of steel-aluminum extruded finned tubes include excellent corrosion resistance and high mechanical strength, and can withstand high temperature and high pressure working environments. The aluminum fins fit tightly on the surface of the steel tube to form a continuous heat conduction path, while the steel tube is made of high-quality carbon steel material, which has good corrosion resistance and mechanical strength. Aluminum fins are made of lightweight aluminum alloy materials, which have excellent thermal conductivity and processing performance, and can effectively increase the heat exchange area and improve the heat exchange efficiency.

In addition, steel-aluminum extruded fin tubes also have good environmental performance. They use environmentally friendly materials and advanced production processes to reduce the impact on the environment. At the same time, they can effectively reduce energy consumption and waste heat emissions during use, which is of great significance for promoting green development and sustainable development.
In the production process, several key factors need to be controlled to ensure product quality, including material selection, extrusion process control, fin design and optimization, and heat treatment and surface treatment.
Material selection involves the selection of steel and aluminum materials and their surface treatment. Extrusion process control includes the control of extrusion temperature, speed and pressure. Fin design and optimization focuses on the optimization design of fin shape, height, spacing and other parameters. Heat treatment and surface treatment are important links to eliminate internal residual stress of materials and improve mechanical properties.
