Lord Fin Tube--Finned tube radiator knowledge

What is finned tube radiator?

Finned tube radiator is the most widely used heat exchanger in gas and liquid heat exchangers. It achieves the purpose of enhancing heat transfer by installing fins on ordinary base tubes. The base pipe can be steel pipe; Stainless steel pipe; Copper pipe, etc. Steel strip can also be used for fins; Stainless steel strip, copper strip, aluminum strip, etc.

Whats the structural principle of finned tube radiator?

All cold and heat exchangers that add fins to the heat exchange tubes to increase the heat dissipation area can be classified as "fin and tube radiator".

Finned tube radiator can be divided into wound type according to the structure of fins; Cascade type; Welding pad type; Plate rolling type. The commonly used material is steel; stainless steel; Copper; Aluminum, etc.

What the usage of finned tube radiator?

The most widely used finned radiator is steel aluminum finned tube (wound steel aluminum composite finned tube, rolled steel aluminum composite finned tube), which uses the pressure resistance of steel pipe and the efficient thermal conductivity of aluminum, and is compounded on a special machine tool. The contact thermal resistance is almost zero at 210 ℃.

The 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. It is widely used in textile, printing and dyeing, petroleum, chemical industry, drying, electric power and other fields.
