Stacked Fin

The stacked fin technology employs micro-scale metal sheet laminating technology (material: 0.05 - 0.2mm thick 6063 aluminum alloy/titanium alloy foil), and through nanoscale gap control (0.3 - 1.2mm), constructs a three-dimensional honeycomb-shaped airflow network to achieve a breakthrough balance between thermal resistance and pressure loss.

● Ultra-thin sheet processing: Laser cutting tolerance ±0.01mm (Surface roughness Ra ≤ 0.8μm)

● Solid-state diffusion welding: Grain interface growth occurs across the interface in a vacuum environment at 580℃ (shear strength > 120 MPa)

● Turbulence generator: Pre-set micro-turbulence structure at the edge of the fins (depth 0.1mm, spacing 2mm)

● Fin density: 80 - 150 fins per inch (4 times higher than traditional process)

● The heat exchange area per unit volume is ≥ 5000㎡/m³ (the measured thermal resistance is < 0.1℃/W)

● Bionic fractal flow channel design reduces wind resistance by 22% (compared to parallel fins)

● The local Reynolds number Re is greater than or equal to 2500, and the forced convective heat transfer coefficient is 510 W/m²K.

● The thermal conductivity of the diffusion welding interface is 220 W/m·K (98% of the base material)

● Thermal cycling test (-55℃ to 150℃) - no layering failure occurred

● Support gradient density stacking (40 fins/inch at the bottom → 120 fins/inch at the top)

● Compatible with micro-liquid cooling integration (integrated Φ0.6mm micro tubes, dual-mode heat dissipation power ≥ 1kW)
