Finned radiator

Fin radiator is a widely used heat exchange device in gas and liquid heat exchangers. The purpose of enhancing heat transfer is achieved by installing fins on ordinary base pipes. The base pipe can be made of steel pipe; Stainless steel pipe; Copper pipes, etc. Fins can also be made of steel strips; Stainless steel strip, copper strip, aluminum strip, etc.

Fin type radiators are mainly used for air heating in drying systems and are the main equipment in hot air devices. The heat medium used in radiators can be steam or hot water, or thermal oil.

The finned radiator consists of three rows of parallel spiral finned tube bundles in the air flow direction. The processing technology of the SRZ type finned tube bundle is to use a mechanical winding method to wrap a 0.5 * 10mm steel strip around an 18mm seamless steel tube, and then hot-dip galvanized. It can also be made of stainless steel tube and stainless steel strip to achieve full stainless steel heat dissipation. The SRL type radiator is a finned radiator made of rolled steel tube and aluminum strip, with a larger heat dissipation area per unit length than the SRZ type.

SRL frame finned tube radiator is a new type of energy-saving radiator that is enclosed by finned tube bundles or bimetallic composite finned tubes. Tests have shown that it performs better than ordinary L-shaped radiators and has a heat transfer efficiency nearly half that of steel tube and steel plate radiators.

SRL type frame finned tube, all aluminum fins are tightly wound on seamless tube using double LL process, and the composite tube is formed by rolling pure aluminum on seamless tube. Each unit has a thickness of 200mm and is assembled with multiple units to form a closed wind tunnel, resulting in good heat dissipation performance.

The SRL frame finned tube radiator allows for a working pressure of 1.2-0.4MPa and a temperature below 350 degrees Celsius (bimetallic composite finned tube).

The finned heat exchanger adopts mechanical winding, and the contact surface between the heat dissipation fins and the heat dissipation tubes is large and tight, resulting in good and stable heat transfer performance. The resistance of air passing through is small, and steam or hot water flows through the steel tube. The heat is transferred to the air passing between the fins through the fins tightly wound on the steel tube, achieving the effect of heating and cooling the air.
