In order to save energy, reduce consumption and reduce emission, the use of Finned Tubes for air heat exchangers is more energy-saving and environment-friendly through the continuous optimization of laser welding process. Our air Heat Exchanger uses finned tubes with base tube thickness of 0.8-1.5mm and fin thickness range of 0.3-1MM. It breaks through the material limit and can be processed with different materials. This will not cause waste of material costs. High Penetration Rate can prevent gap corrosion, prolong service life and reduce heat transfer resistance. There are mainly carbon steel laser welded spiral finned tubes and Stainless steel laser welded spiral finned tubes to meet the needs of different use environments. The Finned Tube for air heat exchanger is easy to be processed twice. It can be directly coiled or bent, making the processing of small diameter finned tube possible.
Laser Welded Finned Tube is a relatively mature and Stable finned tube product with good advantages:
1. The thickness of base tube can be 0.8-1.mm, and the thickness of fin can be 0.3-1.mm, saving material cost.
2. High permeability can prevent interstitial corrosion, prolong service life and reduce heat transfer resistance.
3. Different materials can be used for processing.
4. It is easy for secondary processing and can directly curl and bend pipes.
5. The welding heat affected zone is small, the metallographic change is small, and the small diameter Fin Tube can be processed.
Finned Tube radiators for boilers are made of seamless steel pipes, and the surface is usually sprayed with anti-rust paint or silver powder for surface treatment, so the radiators are not easy to corrode, and have been widely used in industries such as industry and agriculture. The Finned Tube radiator has the characteristics of wear resistance, corrosion resistance and high pressure, and is not easy to crack during use. High Frequency Welded Finned Tubes are recognized as an excellent heat-dissipating element among the current heat-dissipating elements, and the structure of the heat-dissipating element produced by high-frequency welding process is more compact and the heat dissipation efficiency is higher. Users choose high-frequency welding Fins The use of the tube as a heat dissipation element is also more assured and reliable. The outer wall of the Finned Tube radiator is sprayed with anti-rust paint or silver powder for anti-corrosion, and the inner wall is sprayed with an anti-corrosion layer to prevent water from corroding the inner wall of the radiator. The radiator has extremely high corrosion resistance and durability. It is a safe and energy-saving heat dissipation equipment. With the development of finned tubes, its application range has become more widespread.
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.
