Aluminium Finned Tube
Fin tubes are the principal components of heat exchange equipment, and their role is to augment the heat dissipation area and enhance the overall heat exchange efficiency. Particularly, the aluminum fin tube technology, in a non-corrosive environment, plays a vital role in waste heat recovery, boiler renovation, and various industrial processes.
Product Introduction
Aluminum fin tube is a highly efficient heat exchange element. It greatly increases the surface area of the tube outside that contacts the fluid by processing a large number of aluminum fins on the surface of the base tube, thereby improving the heat transfer efficiency.
Product Features
Efficient Heat Conduction
The presence of aluminum fins greatly increases the heat exchange surface area, usually 15-20 times the surface area of the bare tube. This design increases the heat exchange efficiency per unit area by about 40-60%.
Light Weight
The density of aluminum is about 2.7 g/cm³, which is only about 30% of copper (8.9 g/cm³) and 65% lighter than stainless steel (7.9 g/cm³). Using aluminum fin tubes in large air-conditioning systems can reduce the weight of the entire system by 20-30% and reduce the load on the building structure.
Corrosion Resistance
A dense oxide film will naturally form on the aluminum surface. This oxide film can effectively prevent the internal metal from being further oxidized and corroded. Therefore, under normal atmospheric conditions, the corrosion rate of aluminum fin tubes is only 0.0001 mm/year, which is much lower than that of steel fin tubes.
