Descripción del Producto
Aluminum Heat Sinks For Electronic Component Thermal
Precision Extrusion Technology
Our aluminum heat sinks utilize precision extrusion molding technology with specialized custom molds and high-precision extrusion equipment. The core integrates 6061/6063 high-purity aluminum alloy ingots into a single piece, eliminating the need for complex processes like splicing and welding. This approach fundamentally resolves thermal conduction faults and structural looseness 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
  • Fin tooth pitch uniform 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
High-Efficiency Production
Compared to welding and casting processes, our extrusion molding technology enables high-speed, large-scale continuous production with over 50% increased efficiency. Batch production ensures exceptional consistency in product dimensions and thermal performance without individual variations.
  • Ideal for mass production needs in photovoltaic power plants and new energy production lines
  • Effective production cost control
  • Simple process with yield rates exceeding 98%
  • Significantly reduced production losses
  • Enhanced cost-effectiveness for bulk procurement requirements
Precision Surface Treatment
Following extrusion molding, installation surfaces and positioning holes undergo CNC precision milling and grinding to achieve superior surface quality and dimensional accuracy.
  • Installation surface smoothness: Ra0.8μm or better
  • Flatness error: ≤ 0.02mm
  • Seamless fit with equipment core heating elements
  • Significantly reduced contact thermal resistance
  • Prevention of local heat accumulation at heat source points
  • Rapid heat conduction to dissipation fins
  • Precision positioning holes for direct assembly
  • Improved equipment assembly efficiency with reduced errors
Advanced Surface Protection
To address aluminum alloy's susceptibility to oxidation and corrosion, our heat sinks undergo specialized surface treatments including anodizing, sandblasting, or electrophoretic coating after extrusion molding.
  • Dense oxidation protective layer formation
  • Enhanced anti-oxidation and anti-corrosion properties
  • Superior dust-proof and wear-resistant performance
  • Resistance to industrial environment contaminants including dust, moisture, and oil
  • Prevention of surface detachment and thermal conductivity degradation
  • Optimized heat exchange efficiency
  • Reduced obstruction from dust and scaling
  • Long-term stable heat dissipation performance
