"The speed of laser welding is very high - up to 9 meters per minute, so the heat input to the metal is very small, which means the metal is heated at high power, but the speed is very high, and during the passage of the beam it has time to melt, and flow to the pipe And adhere, while the pipes don't have time to heat and deform, which cannot be achieved by condenser welding. Our products are 1.5 times cheaper than similar products, but the welding quality is better, and the heat dissipation efficiency is increased by 15%.
Finned Tube Laser Welded Finned Tube.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.
Since Finned Tubes are not used, the outer surface area is not significantly larger than the inner surface area. Therefore, the fluid with the lowest heat transfer coefficient will determine the overall heat transfer rate. When the heat transfer coefficient of the fluid inside the tube is several times larger than that of the fluid outside the tube, the overall heat transfer rate can be greatly improved by increasing the external surface area of the tube.
product description
Finned Tubes, also known as heat sinks, are divided into single-metal Finned Tubes and bimetallic Finned Tubes.
Single metal finned tube is rolled from aluminum tube as a whole, called aluminum rolled finned tube, has no contact thermal resistance, high strength, heat resistance and mechanical vibration, good thermal expansion performance, and has 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.
Bimetal composite finned tubes are divided into steel-aluminum composite Finned Tubes and copper-aluminum composite finned tubes. Steel-aluminum composite finned tubes are made of (steel tubes, aluminum tubes; or stainless steel tubes, aluminum tubes) and then rolled out of fins, copper-aluminum composite finned tubes are made of (copper tubes, aluminum tubes) and then rolled The fins produced have the advantages of tight combination, small thermal resistance, good heat transfer performance, high strength, small flow loss, strong anti-corrosion performance, not easy to deform under long-term cold and hot conditions, and long working life.
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 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 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. 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.
Advantages of Laser Welded Finned Tubes
1. The laser welding 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
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 (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 of the parent metal.
