Specifiche tecniche
Progressive Extrusion Technology
The production of high-profile fins from a solid aluminum wall requires a carefully managed multi-stage extrusion process. Nexmek blades are profile-calibrated to distribute rolling forces evenly, preventing material tearing and ensuring a smooth, mirror-like finish on the fin flanks.
- Synchronized multi-blade rolling sequence
- Precision tip shaping for aerodynamic efficiency
- Maintains critical base-wall thickness during extrusion
High-Fin vs. Standard Performance
High-fin aluminum tubes are specifically designed to overcome the low heat transfer coefficients of the air-side in gas-to-liquid exchangers.
| Specification | Standard Low-Fin | Nexmek High-Fin |
|---|---|---|
| Typical Fin Height | 1.5 - 2.5mm | 8.0 - 15.0mm |
| Surface Area Ratio | 3x - 5x | Up to 15x+ |
| Typical Fin Pitch | 26 - 50 FPI | 7 - 12 FPI |
| Cooling Efficiency | Standard | Extra High (Air-Side Focus) |
Maximized Thermal Conductivity
By eliminating the air gap found in wrapped or tension-wound fins, our rolled high-fin technology provides a continuous metallurgical path. This ensures 100% thermal contact throughout the life of the heat exchanger, making it the preferred choice for dry coolers, air-cooled condensers (ACC), and industrial cooling towers.
