The core of the aluminum radiator utilizes precision extrusion molding technology, integrating 6061/6063 high-purity aluminum alloy ingots into a single piece without requiring complex processes like splicing and welding. This eliminates thermal conduction faults and structural weaknesses found in traditional spliced radiators.

• Accurate control of fin height, density, and thickness
• Flexible formation of various structures including dense teeth, wide surfaces, and irregular shapes
• Uniform fin tooth pitch error ≤ 0.1mm
• Maximized heat dissipation area with strong structural rigidity
• Excellent deformation resistance and vibration resistance
• Long-term high load operation without structural failure

Compared to welding and casting processes, aluminum heat sink extrusion molding enables high-speed, large-scale continuous production with significant advantages:

• Production efficiency increased by more than 50%
• Exceptional consistency in product size and heat dissipation performance
• No individual differences in batch production
• Ideal for mass production needs of photovoltaic power plants and new energy production lines
• Yield rate exceeding 98% with minimal production losses
• Effective cost control for bulk procurement requirements

After extrusion molding, installation surfaces and positioning holes undergo CNC precision milling and grinding:

• Installation surface smoothness of Ra0.8μm or better
• Flatness error ≤ 0.02mm
• Seamless fit with core heating elements
• Significant reduction in contact thermal resistance
• Prevention of local heat accumulation
• Precision positioning holes ready for direct assembly
• Improved equipment assembly efficiency and reduced labor costs

To address aluminum alloy's susceptibility to oxidation and corrosion, heat sinks receive comprehensive surface treatments:

• Anodizing, sandblasting, or electrophoretic surface treatments
• Dense oxidation protective layer formation
• Enhanced anti-oxidation and anti-corrosion properties
• Superior dust-proof and wear-resistant characteristics
• Resistance to industrial environment hazards including dust, moisture, and oil
• Prevention of surface detachment and thermal conductivity degradation
• Optimized heat exchange efficiency and improved heat dissipation stability
