Product Advantage
High Thermal Efficiency Backed by Material & Design: The 6063-T5 aluminum alloy’s thermal conductivity (165-185W/(m·K)) ensures fast heat absorption, while louvered fins (density 30-45 fins per linear inch) create turbulent airflow—boosting dissipation efficiency by 35% vs. flat aluminum plates. For 150W LED high bay lights, it keeps LED junction temperatures below 60℃, avoiding light decay and extending lifespan to 80,000 hours.
Durable Corrosion Resistance for Long-Term Use: The surface undergoes 12-22μm thick anodizing treatment, forming a non-porous oxide layer that resists 1200 hours of neutral salt spray testing (ASTM B117). This makes it suitable for coastal outdoor lighting or humid industrial workshops, with a service life of 7-9 years—twice that of uncoated aluminum heat sinks.
Customizable to Fit Diverse Heat Needs: Supports full customization of fin type and dimensions: straight fins for slim consumer electronics (e.g., 8mm height for smartphone chargers), pin fins for high-power industrial drives (e.g., 300mm height for frequency converters), and louvered fins for low-noise HVAC systems. CNC machining ensures ±0.04mm tolerance, enabling tight fits with non-standard component sizes.
Lightweight & Cost-Effective for Mass Applications: With a density of 2.7g/cm³, it is 65% lighter than copper heat sinks—reducing equipment weight by 25% for portable devices (e.g., IoT sensors). Extrusion production (output up to 900m/h) lowers costs by 22% vs. machined alternatives, supporting MOQ 30 pieces for small batches and 1000+ pieces for large-scale orders.

Product Uses
1. Consumer Electronics Cooling: Used for USB chargers, laptop CPUs, and smart router chips. The straight fin design (8-15mm height) fits slim device casings, absorbing heat from 10-30W components and reducing temperatures by 20℃—preventing charger overheating or router signal drops.
2. LED Lighting Systems: Ideal for 50-200W LED streetlights, floodlights, and indoor downlights. The louvered fins enhance airflow, dissipating heat from LED chips to maintain brightness at 92% of initial levels after 6000 hours. The anodized surface resists rain and dust, ensuring reliable use in outdoor gardens or parking lots.
3. Automotive Electronics: Applied to EV battery management systems (BMS) and LED headlights. The pin fin structure handles 100-300W heat loads during EV fast charging, keeping battery temperatures below 45℃ to avoid thermal runaway. The material’s shock resistance (impact strength ≥9kJ/m²) withstands vehicle vibrations.
4. Industrial Automation: Cools 200-500W motor drives, PLCs, and sensor modules in factories. The high-height pin fins (200-320mm) dissipate heat in enclosed control cabinets, reducing component temperatures by 28℃ and lowering maintenance frequency by 45%—critical for 24/7 production lines.
Product Operate Guide
Pre-Installation Preparation: Confirm the heat sink’s fin type and dimensions match the component’s heat output (e.g., pin fins for ≥100W devices) and installation space (reserve 3-5mm for airflow). Clean the heat sink’s contact surface and component with isopropyl alcohol to remove oil—ensuring no barriers to heat transfer.
Installation Steps: Apply a thin layer of thermal grease (thickness 0.15-0.2mm, thermal conductivity ≥3.2W/(m·K)) to the heat sink’s base. Use M2-M6 screws to fasten it to the component, tightening to 3-7N·m (avoid over-tightening to prevent base deformation). For vibration-prone scenarios (e.g., automotive), add spring washers.
Post-Installation Verification: Use an infrared thermometer to check the heat sink’s surface temperature—should be ≤65℃ for electronics, ≤90℃ for industrial drives. Ensure fins are not bent (bent fins reduce dissipation efficiency by 15-20%).
Maintenance Tips: Clean fin gaps monthly with compressed air (pressure ≤0.5MPa) to remove dust. For outdoor use, inspect the anodized surface every 6 months; touch up scratches with anti-rust aluminum paint.
FAQ
1. Q: What if the component’s heat output exceeds the heat sink’s standard capacity?
A: We can customize with embedded copper heat pipes (thermal conductivity 385W/(m·K)) to boost capacity by 60%—suitable for 500-800W devices. Lead time for this customization is 8-10 working days.
2. Q: Can the heat sink be used in dust-heavy industrial environments?
A: Yes, choose the sandblasted surface (creates a rough texture that resists dust buildup) and add a dust cover. We also offer monthly maintenance kits for heavy-dust settings.
3. Q: What’s the difference between louvered and pin fins in terms of function?
A: Louvered fins are quieter (ideal for indoor lighting) and excel in low-airflow environments; pin fins have larger surface area (better for high-power industrial devices) but generate slightly more airflow noise.
