Copper finned tube is a heat transfer element, which is widely used in the industrial field, especially in equipment requiring efficient heat transfer. 

The following is a detailed introduction to the copper finned tube:

Structure: The copper fin tube is usually composed of two parts: the base tube and the fin. The base tube is the main body of the finned tube, which is generally made of copper tube, 

and the fin is a heat transfer element attached to the outer surface of the base tube, which is generally made of materials with good thermal conductivity such as aluminum and copper.

Features: Copper finned tube has the advantages of high thermal conductivity, strong pressure resistance, corrosion resistance, good ductility and so on.

 This allows the copper fin tube to maintain efficient heat transfer performance in the temperature range of -10 degrees to +160 degrees, so it is often used in industrial refrigeration radiators, air coolers, condensers and other equipment.

Manufacturing process: The manufacturing process of copper fin tube includes the steps of material preparation, fin molding and welding of fin and base tube. First of all, 

it is necessary to prepare high-quality metal materials such as copper and aluminum as raw materials, and to ensure that their quality meets manufacturing requirements through inspection. 

Then, the metal sheet is processed into fins with a certain shape and size by mechanical forming, stamping forming, rolling forming and other methods. Finally,

 the formed fin is welded with the base tube. Common welding methods include high-frequency welding, argon arc welding, laser welding and so on.

Technical parameters: The technical parameters of the copper fin tube radiator include the heat dissipation area, fin spacing, fin height, base tube diameter, material, wind resistance and heat transfer coefficient. 

The larger the heat dissipation area, the stronger the heat dissipation capacity of the radiator; Parameters such as fin spacing, fin height and base tube diameter will affect the heat dissipation effect and the resistance of air flow.

 The selection of materials needs to consider factors such as thermal conductivity and corrosion resistance; Wind resistance and heat transfer coefficient are important indexes to measure the performance of heat sinks.

In short, copper finned tube, as a high-efficiency heat transfer element, plays an important role in industrial production. Through reasonable manufacturing process and technical parameter selection, 

the performance and use effect of copper finned tube can be further improved.
