In order to improve the heat exchange efficiency, fins are usually added to the surface of the heat exchange tube to increase the outer surface area (or inner surface area) of the heat exchange tube, so as to achieve the purpose of improving heat exchange efficiency. Such heat exchange tubes are called fins. Sheet tube. What are the classifications of Finned Tubes ? Let's find out together.
Finned Tubes are divided into square Finned Tubes, spiral finned tubes, longitudinally finned tubes, spiral serrated finned tubes, and inner Finned Tubes according to shape and structure;
Finned Tubes are divided into: single metal Finned Tubes, bimetallic composite Finned Tubes;
Finned Tubes are classified according to different processing techniques: rolled Finned Tubes, welded finned tubes, rolled formed Finned Tubes, and suit formed Finned Tubes.
Single metal Finned Tube and double metal composite finned tube
The single-metal finned tube is integrally rolled from an aluminum tube, has no contact thermal resistance, high strength, heat resistance and mechanical vibration, good thermal expansion performance, and has a considerable expanded heat transfer surface. The Heat Exchanger made of this finned tube is a kind of heat exchanger with a wide range of uses. Bimetal composite Finned tubes are made of copper-aluminum tubes (or steel tubes, aluminum tubes; or Stainless steel tubes, aluminum tubes) and then rolled fins, which have tight combination, small thermal resistance, good heat transfer performance, and high strength. , small flow loss, strong anti-corrosion performance, not easy to deform under long-term cold and hot conditions, and long service life. The overall rolled fin has no burrs, no wrinkles, and is Easy To Clean . It is easy to remove the condensed water on the outer surface of the fin when the heating and air conditioning project is wet and cold. It is Not Easy To Accumulate Dust and scale when using heat such as dry heating and AC occasions. The aluminum rolled finned tubes and bimetal composite finned tubes produced by our factory. The surface is treated with anodic oxidation, the color is beautiful and generous, which can effectively prevent surface corrosion.
Laser Welded Finned Tubes have a certain ability to prevent dust accumulation. In the concept of treating more, the use of finned tubes is a fusion of moods, which effectively carries many different skills in use. It is also an effective way of using it.
The application of Finned Tubes is now very extensive. Its main purpose is to perform heat exchange, so it is mainly installed on the surface of the heat exchange Tube to improve heat exchange efficiency. For the Finned Tube, its performance has certain requirements, mainly including wear resistance, stability, etc., especially when it is used in a harsh environment, its performance is required to be good. In addition to low contact thermal resistance and has good dustproof ability.

Finned Tubes are fins added to the surface of heat exchange Tubes and are a type of heat exchange elements. The heat exchange element has increased fins, which increases the surface area, so that better heat exchange can be achieved. Since finned tubes are installed on equipment like boilers, they must stand the test of high temperature. Therefore, when purchasing finned tubes, you must choose the following finned tubes with outstanding capabilities.
First of all, the selected finned tubes must have Strong Corrosion Resistance
If the selected finned tube is not strong in corrosion resistance, it is easy to be corroded in a high temperature environment
Second. Finned tubes must have strong wear resistance
If the Finned Tube is worn, the heat transfer efficiency will also be affected to a certain extent, so it is necessary to choose a finned tube with strong wear resistance.
Third. Finned Tubes should be selected with low contact thermal resistance
Only by choosing finned tubes with low thermal contact resistance can the performance of finned tubes be guaranteed in high temperature environments
Fourth. Finned Tubes should be selected with strong stability
Only by choosing Finned Tubes with strong stability can the heat transfer performance not be affected in high temperature environment
Fifth. Finned Tubes must have good dust resistance
Finned Tubes are not easy to replace because they work in a high-temperature environment, so it may cause dust accumulation in the long run. Therefore, when purchasing finned tubes, you should choose finned tubes with good dust resistance.
product introduction
Single metal Finned Tube and bimetallic composite Finned Tube
The single-metal finned tube is rolled from an aluminum tube as a whole, has no contact thermal resistance, high strength, heat resistance and mechanical vibration, good thermal expansion performance, and has a considerable extended heat transfer surface. The heat exchanger made of this kind of finned tube is a kind of heat exchanger with wide application. Bimetal composite finned tubes are made of copper and aluminum tubes (or steel tubes, aluminum tubes; or stainless steel tubes, aluminum tubes) after compounding and then rolling out fins, which have tight combination, small thermal resistance, good heat transfer performance, and high strength. , small flow loss, strong anti-corrosion performance, not easy to deform under long-term cold and hot conditions, and long working life. The overall rolled fin has no burr, no wrinkle, easy to clean, easy to remove condensed water on the outer surface of the fin during wet cooling in heating and air conditioning engineering, and not easy to dust and scale in drying heating and other heat exchange occasions. The aluminum rolled Finned Tubes and bimetallic composite Finned Tubes produced by our factory. The surface is anodized, the color is beautiful and generous, and it can effectively prevent surface corrosion.
Specializing in the production of single and double-metal steel-aluminum composite Finned Tubes, welcome to customize the detailed description:
Single and double-metal steel-aluminum composite Finned Tubes Aluminum rolled finned tubes are rolled from aluminum Tubes as a whole, with no contact thermal resistance, high strength, thermal shock and mechanical shock resistance, good thermal expansion performance, and considerable expansion exchange The hot surface, the heat exchanger made of this kind of finned Tube, is more effective than the serial or wound fin heat exchanger. Copper-aluminum composite finned tubes are copper and aluminum tubes that are laminated and then rolled out of fins. They have the advantages of tight combination, small thermal resistance, good heat transfer performance, high strength, small flow loss, and strong corrosion resistance. It is not easy to deform under working conditions and has a long working life. The overall rolled fins are smooth and free of burrs, no wrinkles, easy to clean, easy to remove condensed water on the outer surface of the fins during wet cooling in heating and air conditioning projects, and not easy to dust and scale in drying heating and other heat exchange occasions.
