What are elliptical finned tubes?
Elliptical finned tubes are a type of heat exchanger tube bundle structure that is commonly used in various industrial applications and heating or cooling systems. They are designed to have efficient heat transfer capacity and a large heat transfer surface area, suitable for occasions where efficient heat exchange is required.
This tube bundle structure consists of multiple elliptical tube segments that are arranged at intervals and interconnected to form a dense tube bundle. Each elliptical tube segment has a series of fan-shaped fins, which increase the surface area of the tube segment and thus enhance the heat transfer effect. The elliptical design helps to reduce the size of the tube bundle and improve the flow efficiency of the fluid in the tube bundle.
Elliptical finned tube composition:
Tubes: usually made of seamless steel tubes, rectangular tubes, elliptical tubes and other specifications.
Fins: Made of aluminum sheet or aluminum foil, made by die cutting, shearing or processing, then put on the tube and fixed by welding, riveting, etc.
Function of elliptical finned tube:
Under the premise of a certain heat transfer area, the finned tube string can significantly improve the heat transfer coefficient of the fluid in the tube. By expanding the heat transfer area and improving the heat transfer efficiency, the volume and weight of the heat exchanger can be reduced, and energy consumption can be reduced.
Elliptical finned tube is a heat exchange element composed of a base tube elliptical tube and an outer fin, and its outer fin is connected by stringing technology. This design makes the elliptical string finned tube have the characteristics of low wind resistance and high efficiency, and is particularly suitable for use in large and medium-sized air coolers.
Structural characteristics of elliptical finned tube
The outer fin of the elliptical finned tube is prefabricated with oblique folded holes and retracted to achieve gapless combination, thereby improving heat dissipation and thermal efficiency. This design can achieve gapless combination under normal temperature conditions without welding, sticking, or filling any material, thus becoming a high-efficiency heat exchanger.
Due to its high efficiency and low wind resistance, the elliptical finned tube is particularly suitable for use in large and medium-sized air coolers. Its outer tube convection heat transfer coefficient is 10%-20% higher than that of round tubes, while air resistance is reduced by 15%-25%, which not only improves efficiency but also reduces the energy consumption of fans.
Application fields of elliptical finned tubes
Elliptical finned tubes are usually made of metal materials, such as stainless steel, aluminum alloy or copper, to meet the corrosion resistance requirements under different working conditions. This tube bundle structure can be widely used in chemical, petroleum, pharmaceutical, food processing and other fields for heating, cooling, evaporation or condensation.
Application scenarios of elliptical string finned tubes.
Elliptical finned tubes are widely used in boilers, air conditioners, refrigeration, heat exchangers, automobiles and other fields. In the industrial field, finned tube strings can meet the needs of different industrial fields, improve production efficiency and reduce enterprise
