The single metal Finned Tube is made of aluminum tube rolled as a whole. Finned Tube has no contact thermal resistance, high strength, heat resistance, mechanical vibration, good thermal expansion performance and considerable expansion heat exchange surface. The Heat Exchanger made of this Fin Tube is a kind of heat exchanger with wide application. Bimetallic composite Finned Tubes are copper and aluminum tubes (or steel and aluminum tubes; or Stainless steel and aluminum tubes) which are combined and then rolled into fins. They have the advantages of tight bonding, small thermal resistance, good heat transfer performance, high strength, small flow loss, Strong Corrosion Resistance, not easy to deform under long-term cold and hot conditions, and long service life. The integrally rolled fins are free of burr and wrinkle, Easy To Clean , easy to remove condensation water on the outer surface of fins during wet cooling in heating and air conditioning projects, and difficult to form dust and scale in drying, heating and other heat exchange occasions. Our factory produces aluminum rolled Fin Tubes and bimetal composite fin tubes. The surface is anodized, with beautiful color and can effectively prevent surface corrosion.
stainless steel laser welded spiral Fin Tubes
At the same time, the Laser Welded Spiral Finned Tube has a fully automatic welding process, which saves labor costs; secondly, the laser welded fins are Firm and strong, and the test of high tensile strength is qualified; the laser welding efficiency is higher, etc.
Laser Welding machine is the most advanced laser welding equipment for spiral Finned Tubes. Since the welding process is fully automatic and mechanical, the technological content and quality of Laser Welded Spiral Fin Tubes are superior to conventional cooling tubes.
Laser Welded Finned Tubes Our company has accumulated many years of experience in High Frequency Welding of Finned Tubes, square Finned Tubes, Inlaid Finned Tubes, and rolled composite steel-aluminum finned tubes. Laser Welding Spiral Finned Tubes are used in civil wall-hung boilers, industrial boilers, etc., using German technology. It has just emerged in China, but it has a history of more than ten years in Europe. The advantage is that the contact thermal resistance is zero. Large conversion ratio, light weight, compact volume of the assembled heat exchanger, more energy-saving and environmental protection, meeting the national emission requirements.
Laser Welded Finned Tube is the most advanced product, which has irreplaceable advantages 1: The thickness of the base tube can be 0.4-0.8 mm, and the thickness of the fin can be 0.3-0.8 mm, which greatly saves the material cost compared with other processes. 2: High Penetration Rate, which can prevent crevice corrosion, prolong service life and reduce heat transfer resistance. 3: Break through the material limitation,

and can use different materials for processing. 4: It is easy for secondary processing, and can be directly used for coiling and bending.
Sequential Finned Tube
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 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 accessory product for fresh air units and air handling units. It can also be connected with air ducts for cooling or heating alone.
Fin thickness
The choice of radiator thickness depends on the corrosion and wear of the fluid gas. Typically, thicker radiators will be used in heavily corrosive locations.
How to improve the production efficiency of laser-welded stainless steel Finned Tubes and reduce production costs: the current production efficiency of finned tubes is still very low, and there is still a lot of room for improvement. As long as the development is good, the production cost will be greatly reduced. There are many factors affecting the production efficiency of finned tubes, including the following factors:
Advantages of Laser Welded Finned Tubes
1. The laser Welded Finned Tube (wing tube) wing plane has a high degree of automation, and the welding of the wing to the tube and the winding of the tube are synchronized
2. The welding rate is 100%, the Finned Tube and Fin Laser Welding is firm, and the welding strength is over 600MPa.
3. The precision of the laser welded pipe finishing machine is 0.05mm
Finned Tubes
4. The contact resistance is 0, and the efficient heat transfer of the Spiral Finned Tube is realized through laser welding.
5. Save production costs. The laser welded finned tube (Finned Tube) is less than 2.5mm. Compared with High Frequency Welded Spiral Finned Tubes, the heat transfer area is increased by about 50%, which reduces material costs and reduces the volume of Heat exchangers.
6. The advantage is decisive compared to traditional MAG/HF welding. The finned tube is completely connected with the base tube, the heat transfer is excellent, and the thermal performance of the finned tube is improved by 2.5 times. The continuous welding prevents the notch effect, thereby avoiding the formation of V-shaped corrosion and cracks when the finned tube is swung. The base metal has low calorific value and travel speed up to 20m/min. The thermal shock area within the base tube is minimized. Therefore, it does not include complete melting of the tube and associated metallurgical transformation
Custom Laser Welded Fin Tubes
Laser Welding Of Stainless Steel finned tubes has strong adaptability and is very suitable for heat transfer between gas, gas, liquid, liquid, liquid, and various fluids, and the phase change heat of the set state will occur during operation. Variety. Through the arrangement and combination of flow channels, it can adapt to different heat transfer conditions, such as counter-flow, cross-flow, multi-flow and multi-channel flow.
0 contact resistance, high-efficiency heat transfer of spiral Finned Tubes is realized by laser welding.
Save production costs. The fin spacing of laser welded Finned Tubes (Finned Tubes) is small, less than 2.5mm. Compared with high-frequency welded spiral (spiral) Finned Tubes, the heat transfer area is increased by about 50%, which reduces the material cost and volume of the Heat Exchanger.
