Finned tube product introduction(2)


2. Aluminum rolled finned tubes and copper-aluminum and steel-aluminum bimetallic composite finned tubes produced by our factory Finned radiators are the most widely used heat exchange equipment in gas and liquid heat exchangers. It achieves the purpose of enhancing heat transfer by adding fins to a common base pipe. The base pipe can be made of a steel pipe; a stainless steel pipe; a copper pipe or the like. It utilizes the pressure resistance of steel pipes and the high-efficiency thermal conductivity of aluminum, and is compounded on a dedicated machine tool. Its contact thermal resistance is almost zero at 210 °C. Radiators made of steel-aluminum composite tubes have an irreplaceable cost-effective advantage over other types of finned tube heat sinks. The aluminum rolled finned tube is...


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...


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 ...


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 ...
