Technical Specifications
Maximizing Phase-Change Efficiency
Enhanced surface geometries like T-fins work by creating specialized 'traps' or micro-channels that promote nucleate boiling. Our blades ensure that the geometry of these channels is perfectly consistent, providing the exact hydraulic diameter required for the refrigerant to boil or condense with minimal thermal resistance.
- Significant reduction in LMTD (Log Mean Temperature Difference)
- Enables more compact heat exchanger designs
- Optimized for HFO and natural refrigerants
Surface Geometry Performance Comparison
A technical comparison of how different fin profiles affect the heat transfer coefficient (HTC).
| Profile Type | Surface Area Ratio | Boiling HTC (Relative) | Tooling Complexity |
|---|---|---|---|
| Standard Fin | 2x - 4x | 1.0 | Standard |
| Y-Profile Fin | 6x - 8x | 2.5x | Advanced |
| T-Profile (Turbo) | 10x - 12x | 4.0x+ | Ultra-Precision |
Precision Folding & Undercutting
The challenge in producing T-fins lies in folding the top of the fin without fracturing the copper root. Nexmek's rolling discs use a proprietary 'gentle-deformation' curve that gradually shapes the fin tip into its final enhanced profile, ensuring zero stress-corrosion cracking and long-term tube reliability.
