low Fin Tubes
The fins are rolled on the surface of the plain tube, which can be processed into low-Finned Tubes, condenser tubes, and evaporation tubes to increase the heat exchange area and improve the heat exchange efficiency.
The integral low- Finned Tube mainly relies on the outer rib of the tube (the rib coefficient is 2 to 3) to expand the heat transfer area. Compared with the bare tube, the low-finned tube has a larger surface area under the same metal material consumption. Intuitively, Low Finned Tubes first enhance heat transfer, but in essence, the increase in heat transfer area leads to an increase in heat transfer coefficient. The fins can make the heat transfer surface peel off the fluid layer, increase the disturbance of the heat transfer surface, improve the heat transfer effect, and strengthen the heat transfer twice. The main factors affecting the heat transfer enhancement of ribbed surfaces are fin height, fin thickness, fin spacing and thermal conductivity of the fin material. In addition, since one side of the heat transfer wall extends to the fin surface, the convective heat transfer of the smooth surface and the heat conduction of the bottom wall have a certain influence on the overall heat transfer. The size of the fin pitch of the low-finned tube needs to be determined according to the surface tension of the liquid and the shear force of the liquid film produced by the flow.
The Integral Low Finned Tube is usually machined to form a certain height, a certain piece distance and a certain thickness of the fin on the outer surface of the light tube. Low Fin Tube is mainly used as heat exchange element in condenser and evaporator of air conditioner, and low fin tube is often used in condenser.
It is composed of a light tube and a fin "attached" on it, and the structural parameters are mainly the inner diameter and outer diameter of the fin tube, the wall thickness of the fin tube, the pitch of the fin, the thickness of the fin and the height of the fin.
Low finned tubes are mainly used in condensers and evaporators of heat exchangers such as air conditioners and refrigerators, absorption chillers, and oil coolers; condensers and evaporators in coal and nuclear power plants; marine heat exchangers; gas turbines; petroleum Air coolers in industry, diesel coolers, dryers and heaters in the chemical industry.
Compared with transparent tubes, it has larger external surface area and higher heat transfer performance, and is widely used in various heat exchange fields.
Integral finned tubes using the form of the base tube covered with aluminum tube(the base tube can be carbon steel, Stainless steel, copper) through machine extrusion, forming a tube fin, the fin base and the tube outer wall is close fitting, this fin tubing control can make finned tubes with high heat transfer coefficient and heat transfer performance. Extruded Finned Tube can be made of iron, copper or aluminum tube by compound rolling, which has the advantages of tight bonding, small thermal resistance, good heat transfer performance, high strength, small flow loss, strong anti-corrosion performance, not easy to deformation under long-term hot and cold working conditions, long working life and so on.
