NVIDIA GB200 Server Copper Brazed Cold Plate Liquid Cooler Thermal Solution

NVIDIA GB200/GB300 Server Copper Brazed Cold Plate Liquid Cooler

• Core Structure: Single-chip independent cold plate (compatible with B300 GPU) + 3D-printed titanium alloy microchannels (channel width < 0.3mm)
• Thermal Interface: Gallium-based liquid metal (thermal conductivity: 73 W/m*K), with thermal resistance as low as 0.02 cm²*K/W
• Cooling Capacity: Single cold plate up to 1400W, complete system (72 GPUs) exceeding 100kW
• Fluid Parameters: Compatible with PG25 coolant / deionized water, flow rate: 2-4 m/s, pressure resistance ≥ 10 bar
• Connectors: NVUQD03 quick-disconnect couplings, only 1/3 the size of previous generation, with 252 pairs installed per system

• AI Data Centers: GB300 NVL72 rack-scale AI servers (supporting large language model inference/training)
• Supercomputing / HPC: Large-scale parallel computing tasks (scientific simulation, quantum computing assistance)
• High-Density Computing: Modular computing units such as Meta Clemente 1U 4-GPU compute sleds

We design internal flow channels based on customer-provided power consumption data and heat distribution patterns to meet specific temperature rise and uniformity requirements while maintaining acceptable fluid flow resistance.

Our design process includes comprehensive simulation analysis of temperature and pressure drop, with iterative adjustments to internal parameters until both thermal and hydraulic performance targets are achieved.

Our manufacturing facility is equipped with state-of-the-art equipment for liquid cold plate production:

Our vacuum brazing process joins aluminum plates using filler metal with lower melting points than the base material, creating extremely strong joints without residual corrosive flux. This high-end technology provides uniform heating, precise temperature control, eliminates post-cleaning requirements, and minimizes part distortion.
