What Is G-type fin Tube?
G-type fin tube is a type of wrapped finned tube. At the same time, it is a type of heat exchange element. In order to improve heat exchange efficiency, fins are added to the outer surface of the heat exchange tube, thereby increasing the outer surface area of the heat exchange tube and achieving the goal of improving heat exchange efficiency. The maximum working temperature reaches 400 degrees Celsius.
Manufacturing Process:
On the basis of slotting the outer surface of the heat exchange tube, tightly embed the fins into the slotted outer surface of the heat exchange tube.
Materials:The base tube material of G-type fin tube includes carbon steel, alloy steel, stainless steel, duplex steel, and copper tube. Fin material: aluminum, copper, etc.
Advantages Of L/LL/KL/G fin tubes
Compared with the light tube, L/LL/KL/G fin tubes has a larger outer surface area, higher heat transfer performance, a tight fit between the fins and the base tube, and lower contact thermal resistance. Cufin Tube’s L/LL/KL/G fin tubes has high production efficiency and excellent cost-effectiveness.
How do L/LL/KL/G Fin Tubes work?
Increased Surface Area:
- The embedded fins extend outwards from the base tube, creating a much larger surface area in contact with the surrounding fluid (like air or water).
- This increased surface area allows for more efficient heat exchange between the fluid inside the tube and the fluid outside.
Heat Conduction:
- Heat from the fluid inside the tube is transferred to the tube wall.
- The fins, being in direct contact with the tube wall, efficiently conduct this heat to their outer surfaces.
Heat Transfer to Surrounding Fluid:
- The heat conducted through the fins is then transferred to the surrounding fluid, effectively cooling or heating the fluid depending on the application. In addition, they can also be used for boiler finned tubes
Applications Of L/LL/KL/G Fin Tubes
