1. Basic composition of fin tube
Embedded fin tube mainly consists of base tube and fin. Base tube is the channel for heat transfer medium to flow, usually made of high-quality seamless steel tube or stainless steel tube, with good thermal conductivity and corrosion resistance. Fin is a metal sheet embedded on the outer wall of base tube by special process, which is used to increase heat transfer area and improve heat transfer efficiency.
Datang fin tube source factory is one of the earliest enterprises in China to professionally develop and produce air conditioning, HVAC and heat exchanger equipment. After years of development, the company has been growing in scale.
2. Types and characteristics of fins
There are many types of fins, including rectangular fins, trapezoidal fins, serrated fins, etc. Different types of fins have different characteristics and application ranges.
For example, rectangular fins have simple structure and convenient manufacturing, which are suitable for occasions with low heat transfer requirements; trapezoidal fins and serrated fins have higher heat transfer efficiency and lower flow resistance, which are suitable for high-efficiency heat exchangers.
The material selection of fins is also crucial. Commonly used fin materials include aluminum, copper, stainless steel, etc. Aluminum fins have good thermal conductivity and corrosion resistance, and are relatively low in cost; copper fins have better thermal conductivity, but are more expensive; stainless steel fins have excellent corrosion resistance and are suitable for harsh working environments.
3. Inlay process and connection method
In the production process of embedded fin tubes, the inlay process of fins is a key link. Common inlay methods include welding, brazing, and mechanical inlay. The welding method melts the contact part of the fin and the base tube at high temperature to achieve a firm connection between the two; the brazing method uses low-melting-point brazing filler to fill the gap between the fin and the base tube to form a reliable connection; the mechanical inlay method is to press the fin against the outer wall of the base tube by mechanical means to achieve rapid installation.
In terms of connection methods, embedded fin tubes usually use flange connection, welding connection or threaded connection. Flange connection is easy to disassemble and maintain, but the cost is high; welding connection has a simple structure and good sealing, but it is difficult to install; threaded connection is suitable for small-diameter pipes and is easy and quick to install.
4. Overall structural optimization design
In order to further improve the heat transfer efficiency and service life of embedded finned tubes, researchers have optimized the overall structure.
For example, by improving the shape and arrangement of fins, flow resistance is reduced and heat transfer coefficient is improved; advanced manufacturing processes and technologies are used to improve the connection quality between fins and base tubes to ensure long-term stable operation; for different working conditions and requirements, embedded finned tubes with specific performance are developed to meet diverse application needs.
