Deskripsi Produk
Aluminum Heat Sinks Precision Extrusion Molding
Precision Extrusion Technology
The core of the aluminum radiator utilizes precision extrusion molding technology, employing specialized customized molds and high-precision extrusion equipment to integrate 6061/6063 high-purity aluminum alloy ingots into a single piece. This eliminates the need for subsequent complex processes such as splicing and welding, fundamentally resolving thermal conduction faults and loose structures found in traditional spliced radiators.
This advanced process enables precise control over fin height, density, and thickness, while allowing flexible formation of various structures including dense teeth, wide surfaces, and irregular shapes.
Key Specification: Uniform fin tooth pitch error ≤ 0.1mm
Enhanced Structural Performance
While maximizing heat dissipation area expansion, the extrusion process ensures the overall heat sink structure maintains strong rigidity, excellent deformation resistance, and vibration resistance. This guarantees long-term high-load operation without looseness or structural failure, maintaining stable heat dissipation performance without attenuation.
High-Efficiency Production Advantages
Compared to welding and casting processes, aluminum heat sink extrusion molding enables high-speed, large-scale continuous production with:
- Production efficiency increased by more than 50%
- Exceptional consistency in product dimensions and heat dissipation performance across batch production
- No individual performance variations
- Yield rate exceeding 98%, significantly reducing production losses
This manufacturing approach effectively meets mass production requirements for large-scale procurement in photovoltaic power plants and new energy production lines while maintaining optimal cost control.
Precision Machining & Assembly
Following extrusion molding, installation surfaces and positioning holes undergo CNC precision milling and grinding treatment to achieve:
- Surface smoothness of Ra0.8μm or better
- Flatness error ≤ 0.02mm
This precision ensures seamless fitting with equipment core heating elements, significantly reducing contact thermal resistance and preventing local heat accumulation. The result is rapid heat conduction from equipment to dissipation fins, maximizing aluminum's thermal conductivity advantages.
Precision-formed positioning holes enable direct assembly without secondary processing, effectively improving equipment assembly efficiency while reducing errors and labor costs.
Advanced Surface Protection
To address aluminum alloy's susceptibility to oxidation and corrosion, heat sinks undergo specialized surface treatments including anodizing, sandblasting, or electrophoretic coating after extrusion molding. These processes form a dense oxidation protective layer that provides:
- Enhanced anti-oxidation and anti-corrosion properties
- Superior dust-proof and wear-resistant characteristics
- Resistance to industrial environment hazards including dust, moisture, and oil
This surface protection prevents problems such as surface detachment and decreased thermal conductivity after aluminum oxidation, ensuring long-term stable heat dissipation performance. Additionally, surface treatment optimizes heat exchange efficiency by reducing obstruction from dust and scaling, further improving heat dissipation stability.
