Industrial-Grade Aluminum Heat Sink

This industrial-grade aluminum heat sink is a precision-manufactured component designed for demanding applications that require efficient thermal management. It is typically used to dissipate heat from electronic components, power modules, or mechanical assemblies in industrial equipment. The heat sink features optimized fin geometry and surface treatments to maximize heat transfer from the heat source to the surrounding air. It is engineered for reliability in harsh environments, providing consistent thermal performance under varying load conditions. The product is sold as a standalone component to OEMs and system integrators across multiple industrial sectors.

Key specifications include base dimensions ranging from 200×200 mm to 600×600 mm, fin heights from 20 mm to 80 mm, and fin pitch from 5 mm to 12 mm. The weight ranges from 1.5 kg to 8.0 kg. The surface finish is anodized with a coating thickness of 10–25 μm, conforming to MIL-A-8625. Thermal conductivity is between 150 and 180 W/(m·K) per ASTM E1225, and thermal resistance ranges from 0.05 to 0.15 °C/W. The operating temperature range is -40°C to 150°C; above 150°C, high-temperature alloys may be required. The material grade is 6063-T5 per GB/T 3190, with a minimum tensile strength of 205 MPa. Flatness is ≤0.1 mm per ISO 2768, and surface roughness is Ra 1.6–3.2 μm per ISO 4287. The IP rating is IP54–IP65 per IEC 60529, depending on enclosure and mounting.

All values are reference ranges and must be verified for the specific model and application with the legal manufacturer or supplier. Standards listed are for procurement and verification reference only and do not imply certification or compliance.

The heat sink operates by conducting heat from a heat source through its base into aluminum fins. The heat is then dissipated to the surrounding air via natural or forced convection. The large surface area of the fins enhances heat transfer to the air, while the anodized coating improves emissivity and corrosion resistance. Thermal interface material may be applied between the heat source and the base to minimize contact resistance. The efficiency of heat dissipation depends on factors such as airflow, fin design, and ambient temperature. Proper mounting and thermal interface material application are critical for optimal performance.
