Our Round Heatsink Led 100W Cold Forging Splayed Pin Fin Aluminium Heatsink delivers high-performance thermal management for industries requiring efficient heat dissipation in compact spaces. Crafted from 6063-T6 aluminum (optimal thermal conductivity) using cold forging technology (instead of extrusion), these heatsinks combine 220 W/mK thermal conductivity with splayed pin fin design, achieving 30% lower thermal resistance than traditional extruded solutions . Ideal for 100W LED lighting, power electronics, and automotive applications, our solutions ensure long-term reliability (10,000+ hour lifespan) in high-temperature environments (ambient up to 65°C).
Splayed pin fins (1.5mm thickness, 3mm pitch, 15° splay angle) maximize surface area (2500 mm²/cm) while maintaining low airflow resistance (0.5 Pa at 1 m/s), validated via ANSYS Fluent simulation .
Integrated mounting holes (M3/M4 threads, ±0.1 mm position accuracy) with thermal interface material (TIM) recesses enable direct attachment to PCBs or heat sources, reducing thermal resistance by 15%.
Cold forging enhances material density (2.7 g/cm³) and grain structure alignment, improving thermal conductivity by 10% vs. extruded aluminum and ensuring 1000+ hour salt spray resistance (ASTM B117) .
Black anodizing (12–25 μm thickness, Class II) improves emissivity (0.85) and corrosion resistance, with RoHS-compliant sealants for outdoor use.
Adjust fin height (10–50mm), base diameter (30–150mm), and base thickness (2–6mm) to optimize thermal performance for specific power requirements (50W–200W).
Support for copper plating (5μm thickness) on fins or graphite coating (0.5μm) on base to further enhance heat transfer (up to 20% improvement).
Tested to 100W power dissipation at 25°C ambient temperature with <40°C temperature rise (ΔT = 38°C), verified via thermocouple testing at 10 points across the base .
LED Lighting: Streetlights (IP66 rated, 50,000+ hour lifespan), high-bay warehouse lights (100W–200W), and automotive headlights (operating temp -40°C to +125°C).
Power Electronics: Inverters (300V–600V), motor drivers (10A–50A), and DC-DC converters (efficiency ≥95%).
Automotive: EV battery cooling modules (thermal resistance 0.3°C/W), engine control units (ECUs), and turbocharger intercoolers (pressure drop ≤2 kPa).
Industrial: Laser diodes (50W–150W), resistance welding equipment, and server rack cooling fans (airflow 50–200 CFM).
Thermal Simulation: Free CFD analysis (ANSYS Fluent) to optimize heatsink design for your application, including airflow, power density, and ambient conditions.
Complex Geometry Solutions: Expertise in micro-fin machining (fins ≤0.5mm) for compact electronics and integrated heat pipes (copper/water) for high-power applications.
Full Compliance: RoHS and REACH certifications, with thermal resistance reports (per IEC 60584) and vibration testing (10–2000Hz) data provided for design verification.
