Extruded Embedded Finned Tube Spiral G/L/Ll/Kl Type Aluminum Fin Tube Copper Heat Exchanger Tube for Boiler
Extruded Embedded Finned Tube Spiral G/L/Ll/Kl Type ,Aluminum Fin Tube Copper Heat Exchanger Tube
DESCRIPTION
Application: Mainly used in petrochemical, electric power, paper, tobacco, buildingheating and other industries such as air cooler, air heater and food industry plant proteinpowder, starch and other spray drying system of air heaters.
Working temperature: 230C, using the most advanced CNC L finned pipe throughdigital control to keep segment binding force in the best condition, rolling forming of thetrapezoidal cross section and the heat flux density distribution in size, on the basis ofmaterial saving, greatly improving the thermal efficiency, put an end to the string typefinned tube for segment gap cannot eliminate the contact thermal resistance.
Features
the winding process, high production efficiency, is apart from the uniform,pod heat transfer, wing than high, base tube can be protected from air erosion.
Manufacturing Process
Fin strips (usually aluminum and copper) are folded into an L shape and wound under tension on the surface of the base tube. The feet of the fins are connected together and cover the surface of the fins.
