High Density Fin Array Precision CNC Machined High Density Heat Sink Plate

Syris Precision CNC Machined High-Density Heat Sink Plate

Syris precision-manufactures this large-format aluminum heat sink using multi-axis CNC machining, featuring a dense array of fine-pitch fins engineered to maximize surface area and passive/active thermal dissipation for high-power electronics.

Key Features:

• High-Density Fin Array: Precisely milled parallel fins with consistent thickness, height, and spacing across the majority of the plate, dramatically increasing convective surface area for efficient heat transfer.
• Fine-Pitch Fin Machining: Tight fin-to-fin spacing achieved through precision milling, demonstrating capability for high thermal-density applications where compact heat dissipation is critical.
• Reinforced Frame Border: Solid, flat perimeter frame surrounding the fin field, providing structural rigidity and a stable mounting surface separate from the thermal fin zone.
• Precision Perimeter Hole Pattern: Accurately drilled and countersunk mounting holes along the frame border, enabling secure, flush attachment to an enclosure or adjoining thermal interface.
• Lower Access Cutouts: Multiple precisely milled notches and window openings along the base edge, providing clearance for cable routing, connectors, or adjacent component mounting.
• Fine Machined Surface Finish: Bright, consistent surface finish across fins and frame, ensuring optimal thermal contact and dimensional accuracy across the full plate length.

Manufacturing Capabilities Demonstrated:

• Large-format multi-axis CNC milling of fine-pitch fin arrays
• Precision fin height/thickness control for thermal performance
• Reinforced frame machining for structural stability
• Accurate perimeter hole drilling and countersinking
• Multi-notch clearance cutout machining

Applications:
Ideal for power electronics heat sinks, inverter/converter cooling plates, LED lighting thermal management, or high-power amplifier chassis requiring maximum passive heat dissipation in a compact footprint.
