High-Precision IGBT Copper Heatsink and Aluminum Profile Fabrication

IGBT heatsink fabrication combining red copper and extruded aluminum is the ultimate thermal management solution for high-power electronic systems, inverters, and EV charging stations. At our direct factory outlet in Bac Ninh, Vietnam, VINACNC provides comprehensive manufacturing services from aluminum profile extrusion to Water Cooling Plate fabrication. Utilizing a copper base for direct contact allows for maximum heat absorption from the IGBT module, while the integrated liquid channels in the aluminum extrusion facilitate rapid heat dissipation, ensuring stable system operation under high-load conditions.

Advanced Cutting, Welding, and Water Cooling Technologies

The manufacturing process at VINACNC is executed in-house with specialized techniques:

Hybrid Cooling Integration: Utilizing C1100 copper plates at concentrated heat sources and 6000 Series aluminum extrusions for the cooling frame. This combination minimizes weight and cost while maintaining superior thermal conductivity.
CNC Water Channel Machining: Liquid circulation channels are precisely CNC milled within the aluminum plate, ensuring optimal flow rates. Controlling ultra-fine surface roughness eliminates thermal contact resistance between the component and the heatsink.
Specialized Joining Techniques: Implementing Friction Stir Welding (FSW) or vacuum brazing to join water-cooled aluminum plates, creating high-strength, hermetically sealed solid-state bonds that withstand high pressure without leaking.
Custom Cutting and Finishing: CNC cutting and punching of aluminum profiles according to specific technical drawings, ensuring perfect integration into industrial electrical cabinets and UPS systems.

Professional Export Packaging and Preservation Process

Copper and aluminum heatsink components require strict protection to maintain surface flatness and aesthetics. VINACNC implements a rigorous international standard packaging process for shipping from Vietnam:

Ultrasonic Cleaning: Thoroughly removes aluminum chips, cutting oils, and impurities from water channels using industrial ultrasonic systems before packaging.
Surface Anti-Oxidation: Each product is wrapped in specialized VCI anti-rust paper or protective PE film to prevent salt-air humidity impacts during transit.
Multi-layer Cushioning: Components are placed in shaped foam trays or thick bubble wrap to eliminate vibration and prevent mechanical impact that could deform the fins or precision contact surfaces.
International Standard Crating: Products are packed in fumigated wooden crates (ISPM 15 standard) or high-grammage reinforced cartons with secure strapping.
Traceability Labeling: Clear labeling displaying part codes, specifications, and barcodes for efficient destination logistics control.
