Finned Tube Heat Exchanger

Finned Tube Heat Exchanger is one of Our Main Products.

Finned tubes consist of thin fins wrapped over the tubes to increase the heat transfer area. Straight tube or finned tube product design can be made according to the purpose of use and ambient conditions. It is wound in a certain thickness, height and pitch according to the tube diameter determined as a result of the necessary calculations according to the process requirement and the heat transfer requirement.

Advantages of Finned Tube Heat Exchanger :

1.Energy Efficiency: 30-50 Percent higher efficiency achieved by optimized tube-to-fin contact maximizes heat transfer.
2.Compact System Design: Small footprint fits tight mechanical spaces and equipment cabinets
3.Stable Thermal Performance: Maintains consistent operation under continuous high load conditions.

4.Custom Dimensions: Coil dimensions fin density and tube layout can be tailored to project needs.

5.Reliable Manufacturing Quality: Precision brazing and strict leak testing ensure long term reliability

Get to Know the Finned Tube Heat Exchanger:

The L/LL/KL configuration refers to the shape of the fins on the tube. L-shaped fins have a flat top and a tapered base, while LL-shaped fins have a double-conical structure with a groove to increase the holding force between the fins and the base tube.KL-shape fins are similar to L-shape fins, but with a serrated body to widen the contacts between the fins and the base tube.

In the G configuration, a finned tube type in which the fin is mechanically embedded in a groove towards the inside of the tube and
that groove is locked in place by forcing rollers at the top of the blade centre.

L/LL/KL finned tubes are widely used in air-cooled heat exchangers such as radiators, evaporators and condensers, as well as in
industrial process heating and cooling applications.

L finned tubes, LL (Double L) finned tubes, KL finned tubes (knurled fin tubes) (with aluminum fins)The aluminum fin strip or the
copper fin strip is folded into an L shape and spirally wound tightly under the action of tension on the outer surface of the base
tube. Tension in the fin strip is wrapped around the tube serves to make the fin foot forcefully on the tube, thus hold the fin
firmly in place.
Superior Heat Transfer Coefficient: Uniquely designed fins continuously disturb the fluid boundary layer, effectively increasing the heat transfer coefficient. This, combined with ultra-thin, high-conductivity fins, ensures the equipment achieves industry-leading high efficiency and significant energy savings.

Space Optimization: Utilizing extended secondary heat transfer surfaces, our tube-fin exchangers achieve an ultra-compact structure. Heat transfer area density can reach up to $1000 m^2$ per cubic meter, ensuring maximum capacity in minimal space.

Significant Weight Advantage: The compact structure and high-strength aluminum alloy construction drastically reduce unit weight,lowering freight costs and simplifying on-site installation. Models in steel, copper, and composite materials are also mass-produced to meet custom material specifications.

Multi-Fluid Adaptability: Easily applies to Gas-Gas, Gas-Liquid, Liquid-Liquid, and Phase-Change heat transfer. Our flow path
design supports complex conditions like Counter Flow, Cross Flow, and Multi-Pass flow.
