1. Overview of the 301x51mm Aluminum Heatsink(PDF Drawing Download)
The 301x51mm aluminum heatsink is a cutting-edge thermal management solution engineered for industries where operational reliability is non-negotiable. Leveraging precision extrusion technology and 6061-T6 aluminum alloy, this heatsink achieves 35% higher heat dissipation efficiency than conventional stamped designs, even in environments with extreme temperature fluctuations, corrosive agents, or mechanical vibrations. Ideal for offshore energy systems, heavy machinery, and industrial automation, it ensures consistent performance under thermal loads exceeding 450W.
2. Extrusion Technology & Structural Advantages
Why Extrusion Delivers Superior Performance
Extruded aluminum heatsinks eliminate the weaknesses of multi-part assemblies, offering a seamless structure that enhances durability and thermal transfer. Key innovations in the 301x51mm model include:
-
Optimized Base Thickness: A 12mm-thick base plate ensures uniform heat distribution, validated by ASME thermal analysis standards.
-
Corrosion-Resistant Coating: Type III hard anodizing (60μm) protects against saltwater, chemicals, and UV exposure.
-
Modular Design: Pre-drilled mounting slots accommodate custom brackets for irregular surfaces.
