|---|---|---|
| Fin Type | Plate, Corrugated, Louvered, Wavy, Slit | |
| Fin Pitch | 1.2 mm to 5.0 mm | |
| Fin Height | 5 mm to 20 mm | |
| Fin Thickness | 0.1 mm to 0.3 mm | |
| Tube Attachment Method | Mechanical expansion, Soldering, Epoxy bonding |

This component is used in the following industrial products
Heat exchange components within Air Handling Units that transfer thermal energy to or from air streams
A component within the Cooling Zone that facilitates heat transfer between fluids or between a fluid and a surface to remove excess heat.
A heat exchanger component within a lubrication system that removes excess heat from lubricating oil to maintain optimal operating temperatures.

Manufacturer profiles associated with Fins.
Manufacturer listings support early research and capability understanding. They are not certification, ranking, or transaction guarantees.
The primary function is to increase the surface area of the coil, which enhances the rate of heat transfer between the internal fluid (like refrigerant or water) and the external air or gas, making the system more efficient.
A smaller fin pitch increases surface area and heat transfer but also raises air-side pressure drop and risk of fouling. A larger pitch reduces pressure drop and improves cleanability but decreases heat transfer efficiency. Selection balances thermal performance with airflow resistance.
