Precision CNC Machined Battery Cooling Cold Plate Milling Parts

Syris Precision CNC Machined Battery Cooling Cold Plate

Syris precision-manufactures this large-format aluminum cold plate using advanced multi-axis CNC milling, featuring complex serpentine coolant channels engineered for uniform, high-efficiency thermal management across a large surface area.

Key Features:

• Repeating Serpentine Channel Modules: Multiple identical zig-zag coolant flow cells milled across the plate, providing consistent, repeatable thermal performance across each module while maximizing coolant-to-surface contact area.
• Precision-Milled Flow Geometry: Smooth, consistently radiused channel turns and uniform channel depth/width, minimizing pressure drop and ensuring even flow distribution across all cooling zones.
• Dense Perimeter Hole Pattern: Extensive array of precisely drilled and located mounting/sealing holes bordering the entire plate, supporting a bolted cover plate for a fully sealed, pressure-tight coolant circuit.
• Cross-Zone Flow Connectors: Integrated bridging channels linking adjacent cooling modules, enabling a continuous flow path across the full plate for efficient single-pass or multi-pass cooling.
• Multiple Access Cutouts: Precisely milled rectangular openings positioned across the plate for component pass-through, sensor access, or mounting interface with an adjacent battery module or busbar assembly.
• Fine Machined Surface Finish: Bright, smooth finish on channel walls and sealing surfaces, critical for consistent gasket sealing and low-turbulence coolant flow.

Manufacturing Capabilities Demonstrated:

• Large-format multi-axis CNC milling of complex serpentine channels
• Repeatable, high-precision modular channel geometry
• Dense, accurately located hole drilling for sealed assembly
• Multi-cutout machining for system integration
• Tight-tolerance surface finishing for pressure-sealed applications

Applications:
Ideal for EV battery pack cold plates, energy storage system thermal management, power electronics cooling, or other large-area liquid-cooled systems requiring uniform, high-performance heat dissipation.
