Finned tube product introduction(1)
The finned tube is a highly efficient heat transfer element. Its heat transfer area is several times to several tens of times of the light pipe, which can enhance heat transfer, reduce flow resistance and reduce metal consumption, thereby improving the economic efficiency and operational reliability of the heat exchange equipment. The factory can also process high-frequency welded steel finned tubes and copper-aluminum composite finned tubes according to user needs. The high frequency welded finned tube is a new type of efficient heat exchange element. It is a disadvantage of a heat sink made of string-type and wound fins, and improves a high-efficiency heat-dissipating component using a high-frequency welded finned tube. The finned tube itself is wound around a finned tube. At the same ti...More
Advantages of steel tube aluminum finned radiator
The steel tube aluminum fin type convection radiator has been newly developed in recent years. It combines the mechanisms of metal material conduction, radiation and convection, fully exploits the heat dissipation function of the radiator, and represents the latest achievements in scientific and technological progress. The heat sink adopts new technology and new technology to better solve the problem of tube connection and anti-corrosion inside the tube. The convection heat dissipation can avoid burns and make the indoor temperature uniform and no cold angle. As some industry insiders have said: Radiant radiators bring sunshine-like warmth; convection radiators bring people a true spring-like warmth. Moreover, the convection radiator metal has high heat strength and large pressure, and is ...More
The disadvantages caused by too many fins
Excessive fins can cause the following problems: 1. When the heat transfer area of the fin is doubled, the heat transfer coefficient cannot be doubled, but a discount is required, which is generally (0.9---0.7), and the higher the fin, the discount value. The bigger, even falls below (0.5). This shows that the higher the fins, the lower the fin efficiency and the lower the economics of the fins. 2. If the fins are too high and too dense, it is easy to cause ash accumulation problems, and it is difficult to remove dust. 3. The fins are too high and too dense, which will increase the process difficulty and increase the processing cost. For a 1-meter-long pipe, the total heat transfer area after the fin is increased is A, and when the light pipe area when the fin is not increased is A0, A/A0 ...More
Steel pipe aluminum fin convection radiator (2)
3. Corrosion resistant and long service life. It is not like the all-steel radiator is afraid of oxidative corrosion, and it has strong adaptability and makes users feel at ease. The steel tube aluminum fin convection radiator has the advantages of beautiful appearance, various forms and high overall strength. Aluminum radiator: Aluminum's thermal conductivity is second only to steel, but its weight is much smaller than steel, so aluminum radiators have occupied a large share of new radiators. However, the aluminum radiator cannot be used in an alkaline environment, and the Chinese heating system is required to prevent the boiler and heat exchanger from scaling. The heating medium is required to have a pH between 10 and 12, and an untreated aluminum radiator is used here. In the environmen...More
