1. Precision shovel tooth forming process: laying the foundation for efficient heat dissipation core

Integrated CNC gear hobbing: Using a CNC gear hobbing machine, the entire aluminum/copper profile (6063 aluminum alloy, etc.) is cut into continuous and uniform heat dissipation fins in one go using a dedicated gear hobbing tool. The fins are integrated with the substrate structure, without splicing or welding, eliminating contact thermal resistance from the root, and improving thermal conductivity efficiency by more than 30% compared to riveting/inserting.

2. Efficient assembly and composite process: Strengthen thermal conductivity and structural stability

Stress free assembly process: The tooth forming process of the shovel is cold cutting, with no high-temperature thermal deformation. The internal stress of the substrate and fins is extremely small, and it has strong resistance to vibration and impact. It is suitable for long-term high-speed operation and harsh working conditions; At the same time, the integrated structure has no looseness or detachment, and its service life is extended by more than 50% compared to assembled heat sinks.

3. Surface optimization process: improve durability and heat dissipation efficiency

Hard anodizing process: The aluminum alloy shovel tooth heat sink is treated with hard anodizing, which increases its corrosion resistance and wear resistance by 6 times. At the same time, the oxide film is a porous structure, which can increase the contact area between air and fins, strengthen convective heat dissipation, and improve heat dissipation efficiency by more than 12%.

Passivation/nickel plating process: The copper shovel tooth heat sink is passivated to remove the surface oxide layer and form a dense protective film, avoiding the decrease in thermal conductivity caused by copper oxidation and blackening; The high-end scene adopts nickel plating technology, which has stronger resistance to salt spray and moisture. It can pass salt spray testing and is suitable for outdoor and high humidity environments.

Sandblasting/wire drawing process: By sandblasting/wire drawing the surface of the heat sink, the surface roughness is increased, further expanding the heat transfer area. At the same time, customized matte, wire drawing and other appearance effects can be achieved, balancing practicality and aesthetics, suitable for scenarios with appearance requirements such as consumer electronics and high-end equipment.

4. Full process precision control technology: ensuring batch consistency

Establish a full process quality inspection system from initial inspection to final inspection, and cooperate with equipment such as coordinate measuring instruments, thermal resistance testers, and airflow analyzers to conduct 100% full inspection of the tooth profile accuracy, spacing uniformity, substrate flatness, contact thermal resistance, and heat dissipation efficiency of the heat sink, ensuring small dimensional consistency errors and small fluctuations in heat dissipation efficiency for batch products, and ensuring that each product can stably perform.
