Air Heater Laser Welded Finned Tube
Single and double-metal steel-aluminum composite finned tubes Aluminum rolled finned tubes are rolled from aluminum tubes as a whole, with no contact thermal resistance, high strength, thermal shock resistance and mechanical vibration resistance, good thermal expansion performance, and considerable expansion change. The hot surface, the Heat Exchanger made of this finned tube, is more effective than the serial fin or wound fin heat exchanger. Copper-aluminum composite finned tubes are copper and aluminum tubes that are laminated and then rolled out of fins. They have the advantages of tight combination, small thermal resistance, good heat transfer performance, high strength, small flow loss, and Strong Corrosion Resistance. Under working conditions, it is not easy to deform and has a long working life. The overall rolled fins are smooth and free of burrs, no wrinkles, easy to clean, easy to remove condensed water on the outer surface of the fins during wet cooling in heating and air-conditioning projects, and Not Easy To Accumulate Dust and scale in drying heating and other heat exchange occasions.
The string type is to string (carbon steel, copper, Stainless steel ) tubes (aluminum, copper, stainless steel) pieces together, generally referring to TLS type high-efficiency heat exchangers (commonly known as surface coolers). It adopts the advanced mechanical expansion tube and bridge-type slit double-turned aluminum fin structure. The mechanical tube expansion makes the copper tube and the aluminum fins in close contact, and the bridge-type slit can promote fluid turbulence, destroy the boundary layer, and improve the heat transfer coefficient. The advanced structural form, coupled with the reasonable design of the waterway stroke, the tube distance and the plate distance, make the heat exchanger have the characteristics of good heat transfer performance, small air resistance, compact structure and light weight.

Benefits of using laser to weld Finned Tubes
1. The thickness of the base tube can be 0.8-1.5mm, and the thickness of the pin in operation can be 0.3-1mm. Compared with other process costs during operation, the material cost can be greatly reduced.
2. The Laser Welded Finned Tube has a high welding joint ratio, which can prevent the corrosion in the working time gap, effectively extend the service life and reduce the heat conduction resistance.
3. When laser welding Fin Tube breaks through the material limit, other materials shall be used for processing.
4. The laser Welded Finned Tube is easy to be processed for the second time, and the coil and elbow can be directly processed.
5. The welding heat affected zone is small and the metallographic change is small, so it is allowed to process small diameter Finned Tubes.
Rematerials of Heat Exchange Tubes and condensation tubes shall have heat transfer performance, corrosion resistance, corrosion resistance, wear resistance, strong strength, strong plasticity and easy processing.
1. Winding Finned Tube
Wound-finned finned tubes are all made of (steel, aluminum, copper, stainless steel, etc.) tape-wound (steel, aluminum, copper, stainless steel, etc.) tubes, which are mechanically wound in a spiral shape and have three different pitches: 3.2mm “R”, 4.2mm “M”, 6.5mm “T”.
R chip pitch, small chip pitch and large cooling area, with large heat dissipation;
M chip distance, the larger the chip distance, the smaller the heat dissipation and air resistance;
T piece spacing, suitable for the situation of high steam pressure and low air temperature rise.
3. Sequential finned tube
The string type is to string (carbon steel, copper, stainless steel) tubes (aluminum, copper, stainless steel) sheets, generally referring to TLS type high-efficiency Heat Exchangers (commonly known as surface coolers). It adopts the advanced mechanical expansion tube and double-pass aluminum Fin structure with bridge-type slits. The mechanical tube expansion makes the copper tube and the aluminum fins in close contact, and the bridge-type slit can promote fluid turbulence, destroy the boundary layer, and improve the heat transfer coefficient. The advanced structural form, coupled with the reasonable design of waterway stroke, tube distance and plate distance, make the heat exchanger have the characteristics of good heat transfer performance, small air resistance, compact structure and light weight. It can be widely used in air conditioning, cooling, dehumidification, heating and other projects. It is an ideal supporting product for fresh air units and air handling units. It can also be connected with air ducts for cooling or heating alone.
Finned tubes, also known as heat sinks, are divided into single-metal finned tubes and bimetallic finned tubes.
Single metal Finned Tubes are rolled from aluminum tubes as a whole, called aluminum rolled Finned Tubes, have no contact thermal resistance, high strength, heat resistance and mechanical vibration, good thermal expansion performance, and have a considerable extended heat transfer surface. The heat exchanger made of this kind of fin tube is more effective than the serial fin or wound fin heat exchanger, and it is a heat exchanger with a wide range of uses. Single metal finned tubes can also be made by direct rolling of steel tubes or copper tubes.
