Finned heat sink tubes and steel aluminum composite rolled spiral finned heat sink tubes are more common heat sink tubes currently used in industrial drying systems and various special drying equipment. Set the fin height of each heat sink tube and the distance between the fins, cooperate with the air flow application of the convection fan, and fully ensure that more heat dissipation effects are achieved in the practical application of the heat sink tubes. Whether the steel Finned Tube radiator and the steel aluminum composite Finned Tube Heat Exchanger in the industrial drying equipment can play a better role in heat dissipation, it is necessary to consider the key factors in all aspects in combination with various factors. The Spiral Finned Tube used in the steel finned tube radiator was earlier treated by winding production, and the more Stable and reliable processing technology is high-frequency welding.

Finned tube radiator can be divided into four modes: air cooling, air cooling, water cooling and heat pipe cooling. The following four modes are introduced in detail. Finned tube radiator is air cooling. Finned tube radiator air cooling is also called natural cooling. Generally, it contacts the heating core of electronic components with the profile radiator and transmits according to the natural convection mode of air. Its main advantages are simple structure, convenient installation and low cost. Finned tube radiator air cooling heat dissipation, finned tube air cooling heat dissipation is currently a more common way of heat dissipation.

The oxygen corrosion problem of finned tube radiator has always been the main problem to be solved in the industry. If we want to solve the Fin Tube corrosion problem in the medium containing oxygen, it is very important for the existing technology development. However, with the current management level and capital standards, internal corrosion of Finned Tubes can be prevented first. At present, the finned tube radiator is widely used as the steel aluminum finned tube (wound steel aluminum composite finned tube, rolled steel aluminum composite finned tube), which uses the pressure resistance of steel tubes and the thermal conductivity of aluminum, and is compounded on a special machine tool. The contact thermal resistance is almost zero at 210 ℃. Steel aluminum composite tube radiator has irreplaceable advantages over other types of finned tube radiator. Finned tube radiator is generally used for heating or cooling air, which is characterized by compact structure and large unit heat exchange area.
