Product Advantage
Superior Thermal Conductivity: Made from high-grade aluminum alloys (e.g., 6063 with ~160 W/(m·K) thermal conductivity), these heatsinks efficiently transfer heat away from critical components, reducing operating temperatures by 20–30°C compared to standard solutions.
Customizable Fin Design: Offers diverse fin structures (straight, pin, radial) and densities (up to 50 fins per linear inch) to match specific cooling needs—pin fins excel in turbulent airflow environments, while straight fins suit streamlined designs.
Precision Manufacturing: CNC machining ensures a tolerance of ±0.05mm, enabling seamless integration into tight-spaced assemblies (e.g., automotive engine bays or compact electronics enclosures).
Durable Surface Treatments: Anodizing (clear/black/colored) provides corrosion resistance (≥1000 hours salt spray test), while polishing or sandblasting enhances aesthetics or grip for thermal interface materials.
Versatile Application Range: Operates in -40°C to +150°C, making it suitable for outdoor LED lighting, industrial machinery, and automotive under-hood components, with a service life of 6–8 years.

Product Uses
1. Electronics Cooling: Cools LED drivers, power supplies, and CPU/GPU modules in consumer electronics and industrial control systems. The customizable fin density ensures heat dissipation for 10–200W components.
2. Automotive Applications: Used in engine control units (ECUs), LED headlights, and battery management systems (BMS). Corrosion-resistant anodizing withstands under-hood humidity and temperature fluctuations.
3. Industrial Machinery: Integrates into motor drives, frequency converters, and sensor modules. The precision tolerance (±0.05mm) allows installation in compact industrial enclosures.
4. Outdoor Lighting: Cools high-power LED streetlights and floodlights. The -40°C to +150°C operating range and 6–8-year service life reduce maintenance in harsh environments.
Product Operate Guide
1. Pre-Installation: Verify dimensional compatibility and surface treatment (e.g., anodizing for outdoor use). Clean the heatsink and component contact surfaces with isopropyl alcohol.
2. Installation: Apply thermal grease (thickness: 0.1–0.2mm) or thermal pads. Use M2–M6 screws (torque: 3–8N·m) to secure the heatsink, ensuring even pressure to avoid warping.
3. Maintenance: Inspect annually for debris buildup; clean with compressed air (≤0.6MPa). For outdoor applications, check anodized surfaces for wear and reapply protective coating if needed.
FAQ
1. Q: Can you customize the heatsink for a 200W power module?
A: Yes. We recommend a pin-fin structure with 6061 aluminum (thermal conductivity ~180 W/(m·K)) and anodizing, with a lead time of 7–10 working days for custom molds.
2. Q: What’s the minimum order quantity for a custom fin design?
A: MOQ is 50 pieces for standard customizations (e.g., fin density, size). For fully bespoke fin structures, MOQ is 200 pieces.
3. Q: How does machining tolerance (±0.05mm) benefit assembly?
A: It ensures the heatsink fits precisely into enclosures or against components, minimizing gaps that reduce thermal efficiency.
