Our 100W cold forging round pin fin LED aluminum heatsink is a high-efficiency thermal solution for 100W high-power LED and industrial cooling applications. Made from 6063-T6 aluminum with advanced cold forging technology, it delivers high thermal conductivity (220 W/mK) and up to 30% lower thermal resistance than traditional extruded heat sinks.
The unique splayed pin fin structure maximizes heat dissipation area while keeping airflow resistance low. With a black anodized finish, 1000+ hour salt-spray resistance and RoHS compliance, it ensures stable long-term operation in high-temperature and outdoor environments. We offer full customization — fin height, base diameter, thickness, copper plating and graphite coating — with all products 100% QC tested, precise mounting holes and TIM recesses to reduce contact resistance. Widely used in LED street lights, high-bay lights, automotive headlights, power inverters, DC-DC converters, EV battery modules and industrial laser equipment, with OEM/ODM, CFD thermal simulation and on-site project support available.
Advanced cooling design — splayed pin fins (1.5 mm thickness, 3 mm pitch, 15° splay angle) maximize surface area while keeping airflow resistance low; integrated M3/M4 mounting holes (±0.1 mm) and TIM recesses enable direct attachment to PCBs or heat sources and help reduce contact resistance.
Material & process — cold forging increases material density (2.7 g/cm³) and grain alignment, with up to 10% better thermal conductivity than extruded aluminum; black anodizing (12–25 μm, Class II) improves emissivity (0.85) and corrosion resistance, RoHS-compliant for outdoor use.
Customization options — fin height (10–50 mm), base diameter (30–150 mm) and base thickness (2–6 mm) adjustable for 50–200 W applications; copper plating or graphite coating available to further enhance heat transfer.
Performance validation — tested to 100 W power dissipation at 25 °C ambient with a temperature rise below 40 °C, verified by thermocouple testing across the base.
LED lighting — streetlights, high-bay warehouse lights (100–200 W), automotive headlights.
Power electronics — inverters (300–600 V), motor drivers (10–50 A), DC-DC converters.
Automotive — EV battery cooling modules, engine control units (ECUs), turbocharger intercoolers.
Industrial — laser diodes (50–150 W), resistance welding equipment, server rack cooling.
Thermal simulation — free CFD analysis (ANSYS Fluent) to optimize the heatsink design for your airflow, power density and ambient conditions.
Complex geometry solutions — micro-fin machining for compact electronics and integrated heat pipes (copper/water) for high-power applications.
Full compliance — RoHS and REACH certifications, with thermal resistance reports and vibration testing data provided for design verification.
