Custom Copper Heat Dissipation Coil precision CNC Machining china cnc machining copper alloy parts heat sink coil

The copper heat dissipation coil is a high-efficiency thermal management component designed for applications requiring superior thermal conductivity and stability. Made from high-purity copper (e.g., T2 copper with 99.99% purity), it is formed through precision CNC machining to ensure a compact structure and smooth surface free of text or marks. Its core function is to transfer heat from liquids or steam to air via convective heat dissipation, making it ideal for industrial equipment, electronics, and HVAC systems. The coil is integrated with fins through hydraulic expansion, creating an even heat exchange surface.

1. High Thermal Conductivity and Corrosion Resistance: Copper material offers excellent thermal conductivity (approx. 400 W/m·K) and natural corrosion resistance, extending service life. Tin alloy plating can be added for enhanced protection.
2. Precision Structural Design: CNC machining controls coil spacing and bend angles (e.g., S-type layout) to optimize airflow and prevent heat accumulation. Fins are tightly bonded to tubes via expansion processes, reducing thermal resistance.
3. Lightweight and High Strength: Composite supports (e.g., carbon fiber) reduce weight while maintaining structural integrity under high pressure (up to 25 kg/cm²).
4. Customization Flexibility: Parameters like tube length, diameter (e.g., 6-division or 10-division), and fin spacing can be tailored to spatial and thermal requirements.
5. Clean Surface Treatment: A controlled machining environment ensures no text, logos, or scratches, meeting high-definition imaging standards with a pure white background.

• Electronics Cooling: Servers, power modules, and high-frequency components to prevent overheating.
• HVAC Systems: Fan coil units, air heaters for commercial buildings (hotels, malls).
• Industrial Machinery: Cooling units for injection molding machines and laser cutters to ensure stability.
• New Energy: Battery cooling in electric vehicles, solar thermal collectors for improved efficiency.
