Customized Aluminum Liquid Cold Plate Machining for CPU and GPU

Aluminum Liquid Cold Plate machining is the ultimate thermal management solution for high-performance computing systems, data servers, and professional graphics or mining GPUs. At our precision engineering hubs in Bac Ninh, Vietnam, the application of 6000 Series aluminum alloys combined with multi-axis CNC milling technology enables the fabrication of cooling plates with complex internal micro-channel systems. VINACNC's workflow ensures absolute surface flatness and instantaneous thermal conductivity, helping CPUs and GPUs maintain safe temperature thresholds even under full load operations.

Machining Expertise for CPU/GPU Aluminum Cold Plates at VINACNC

The sophistication of subtractive machining directly determines the cooling efficiency of a liquid cooling system:

Internal Micro-channel Milling: Utilizing micro-endmills to create internal circulation systems within the aluminum plate. This design maximizes the contact area between the coolant and the aluminum, accelerating heat absorption from the processor chips.
Flatness and Surface Roughness Control: The contact surface between the Cold Plate and the CPU/GPU die is machined to micron-level flatness and ultra-fine surface roughness. This allows thermal paste to be spread as evenly and thinly as possible, eliminating thermal contact resistance (Rth).
Premium 6061/6063 Aluminum Materials: High-purity aluminum grades are selected to ensure the best thermal conductivity while maintaining structural stability, preventing warping under flow pressure and temperature fluctuations.
Absolute Sealing Technology: Implementing groove machining for gaskets or surface preparation for Friction Stir Welding (FSW), ensuring the system remains leak-proof throughout its lifespan.

Professional Export Packaging and Preservation Process

CPU/GPU Cold Plates require absolute protection of the contact surfaces and the cleanliness of the channels. VINACNC implements a rigorous international standard packaging process for shipping from Vietnam:

Ultrasonic Cleaning: Thoroughly removes machining oils, residual chips, and impurities from the micro-channels using industrial ultrasonic systems.
Surface Anti-Oxidation: Utilizing specialized VCI anti-rust paper or PE protective film to prevent salt-air humidity impacts.
Multi-layer Cushioning: Each cooling plate is placed in shaped foam trays or thick bubble wrap to eliminate mechanical vibration and impact that could scratch the precision contact surface.
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.
