Fin-tube radiatorA widely used heat exchange equipment in gas and liquid heat exchangers. It achieves enhanced heat transfer by attaching fins to a standard base tube. The base tube can be made of steel pipe, stainless steel pipe, copper pipe, etc. The fins can also be made from steel strip, stainless steel strip, copper strip, aluminum strip, etc.

Any heat exchangers with fins added to the heat exchange tubes to increase the surface area for heat exchange can be categorized as “Finned tubeCooler”。

Finned tube radiators can be categorized according to the fin structure into: spiral finned; shingled finned; brazed finned; and rolled finned. Common materials include steel, stainless steel, copper, and aluminum.

Finned radiators commonly use steel-aluminum fin tubes (wound steel-aluminum composite fin tubes, rolled steel-aluminum composite fin tubes), which leverage the steel tube's pressure resistance and aluminum's thermal conductivity, being compounded on a machine. Their contact thermal resistance is almost zero under 210℃ working conditions.

Steel-aluminum composite tube radiators offer irreplaceable advantages over other types of finned tube radiators.

Fin-tube radiators are commonly used for heating or cooling air, featuring compact structure and a large heat exchange area per unit. They are widely applied in various fields such as textile, dyeing and finishing, petroleum, chemical industry, drying, and electricity.
