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.

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.
Laser Welding Of Spiral Finned Tube
Finned Tube radiator can be widely used in light industry, construction, machinery, fiber, printing and dyeing, electronics, food, starch, medicine, metallurgy, painting and other industries, including hot air heating, air conditioning, refrigeration, condensation, dehumidification, drying, etc.
Heating radiator: one of the radiator applications, including heaters and fan heaters.
Finned Tube radiator structure: heat dissipation, access browser, frame.
The radiating exhaust pipe is made up of a heating pipe, and the heating pipe is made up of a base and a bolt.
The quality of the heat pipe determines the heat transfer effect, the arrangement of the heat pipe affects the wind resistance, and the installation method of the heat pipe determines the resistance to the temperature difference (thermal expansion and contraction).
Common installation methods of finned tube radiators: frame fixing (SRZ, SRL, S), frame support (GL, U).
The frame is fixed, and the heating pipe is directly welded on the frame box. Simple structure, generally used for fruiting bodies or refrigerants below 180. The frame bracket, the heat pipe is welded with the connecting pipe (or elbow) through the frame perforated plate, usually for 180C.
Waste heat recovery includes waste water waste heat recovery and exhaust gas waste heat recovery, and flue gas waste heat occupies a considerable proportion in waste gas waste heat recovery. Today, the editor will tell you what waste heat recovery devices are.
1. Flue gas waste heat recovery device
Also known as flue gas heat exchanger, air preheater, etc., it is popularly explained as: recovering the heat in the flue gas for heating and preheating process production.

1. Flue gas waste heat recovery device
Also known as flue gas heat exchanger, air preheater, etc., it is popularly explained as: recovering the heat in the flue gas for heating and preheating process production.
Generally, waste heat recovery devices mainly include plate heat exchangers and tube heat exchangers.
During years of production, installation, and transformation, we have concluded that for the waste heat recovery of flue gas, the plate structure is more conducive to the full utilization of waste heat of flue gas.

Plate heat exchangers mainly include: high heat transfer efficiency, high waste heat recovery rate; small footprint; low cost; small footprint, etc. These are the advantages of tube heat exchangers.
Heat exchanger manufacturers mainly use the heat energy that will and may be wasted in industrial production for recycling and reuse. In this regard, manufacturers are constantly innovating and improving. The flue gas waste heat recovery device is based on the ordinary heat exchanger, combined with the current situation of energy shortage in the market and environmental protection considerations, how to recycle and purify waste water and waste gas, including flue gas waste heat and flue gas, are the prerequisites for the waste heat recovery device.
2. Waste heat recovery device
Many users call it: wide channel sewage heat exchanger, wide channel heat exchanger.
Due to the large amount of impurities in the waste water, according to the chemical properties and impurity content of the heat exchange medium, a plate heat exchanger or a shell and tube heat exchanger is selected for waste heat recovery.

Finned Tube Heat Exchanger adopts the method of adding finned tube heat exchanger, which greatly improves the heat emission of radiator fins and further improves the role of heat emission of radiator fins. The finned tube heat exchanger is welded with low-carbon environment-friendly steel pipes, which is durable and emits heat for a long time. Our inspection and maintenance during use are still helpful to the service life of radiator fins.
There are many kinds of Laser Welded Finned Tubes in use. In operation, high-frequency welded Finned Tubes are mainly used. Although it is more advanced in product quality and production automation compared with inlay and brazing methods, it is difficult to weld the root of high-frequency welded finned tubes and there are wrinkles at the root, resulting in many shortcomings in heat exchange efficiency and convenient ash deposition prevention. In view of the above reasons and in response to the guidelines and policies on energy conservation and emission reduction.
Technology of laser welding finned tube
1. The thickness of the base tube of the laser welded fin tube can be 0.8-1.5 mm, and the thickness of the fin can be 0.3-1 mm, which greatly saves the material cost compared with other processes.
2. High Penetration Rate can prevent gap corrosion, prolong service life and reduce heat transfer resistance.
3. Break through the material limit and use different materials for processing.
4. It is easy for secondary processing and can be directly used for coil and elbow.
5. The welding heat affected zone is small and the metallographic change is small, which makes the processing of small diameter Finned Tube possible.
