Radiators

Finned radiators are a widely used heat exchange equipment in gas and liquid heat exchangers, which enhance heat transfer by adding fins to a standard base tube.

Base pipe can be made of steel pipe; stainless steel pipe; copper pipe, etc.
The fins can also be made of steel strip; stainless steel, copper, aluminum strips, etc.
Finned tubes added to heat exchangers to increase the surface area for heat exchange can all be categorized as "finned tube radiators."

Working Principle

Fin-tube radiatorAccording to the structure of fins, they can be divided into: helical finned; longitudinal finned; welded finned; rolled finned. Common materials include steel, stainless steel, copper, aluminum, and so on.

Finned radiators currently widely used are steel-aluminum finned tubes (wound steel-aluminum composite finned tubes, rolled steel-aluminum composite finned tubes). They leverage the pressure resistance of steel and the thermal conductivity of aluminum, combined on a machine. Their contact thermal resistance is almost zero under working conditions of 210°C.

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.
Widely applied in textile, dyeing, petrochemical, drying, electricity, and other fields.
