1. Overview of steel aluminum composite Finned Tube:

The processing technology of steel aluminum composite finned tube is to first process the double metal composite tube on the aluminum tube and copper tube, and then, after mechanical cold rolling, make use of the physical characteristics of aluminum tube, and use the tube centered on the steel tube and the Fin Tube closely combined with the aluminum needle made by cold rolling. When the steel aluminum composite fin tube radiator is wet cooled in the heating and air-conditioning project, it is easy to remove the condensation water on the external surface of the fin, and it is not easy to produce dust and dirt in the drying heating and other heat exchanges.

2. Characteristics of steel aluminum composite finned tube:

1. Solid combination, small thermal resistance and good heat transfer performance.

High strength and small flow loss.

3. It has strong anti-corrosion performance, is not easy to deform under long-term cold and hot conditions, and has a long service life.

Finned tube radiator (radiator, also known as heat discharge, air heater and air Heat Exchanger) is the main equipment of heat exchanger, including cooling air with refrigerant, heating air with heat medium or recovering air waste heat with cold water. Access

Warm water, steam or high-temperature heat transfer oil can heat the air, and salt water or low-temperature water can be used to cool the air.

Fin Tube

Finned tube radiator can be widely used in light industry, construction, machinery, fiber, printing and dyeing, electronics, food, starch, medicine, metallurgy, coating and other industries, including hot air heating, air conditioning, cooling, condensation, dehumidification, drying, etc.

Heating radiator: one of radiator applications, including heating fan and heater.

Finned tube radiator structure: heat dissipation, access browser, frame.

The radiating exhaust pipe is composed of a heating pipe, which is composed of a base and a pin. The quality of the heat pipe determines the heat transfer effect, the arrangement of the heat pipe affects the air resistance, and the installation method of the heat pipe determines the resistance to temperature difference (thermal expansion and contraction).

Common installation methods of finned tube radiator: frame fixing (SRZ, SRL, S), frame support (GL, U).

The frame is fixed, and the heating tube is directly welded to the frame box. The structure is simple, and it is generally used for fruit bodies or refrigerants below 180. Frame support, heat pipe is welded with connected pipe (or elbow) through frame perforated plate, usually used for 180C.
