Precision Machined Liquid Cold Plates

Applications & Functions

Our precision machined liquid cold plates (high-efficiency water-cooling heat sinks and internal micro-channel assemblies) are engineered specifically to capture, transfer, and dissipate extreme localized heat flux from modern high-power electronics. Manufactured using multi-axis CNC milling on high-conductivity aluminum or copper stock, these cold plates feature dense internal flow channels or integrated fin structures designed to maximize liquid-to-metal heat exchange. They ensure consistent operational temperatures, prevent thermal throttling, and protect sensitive components in liquid-cooled systems.

They are extensively utilized across high-density electronic, automotive, and industrial thermal management sectors:

• High-Performance Computing & Data Centers: Serves as the primary direct-to-chip liquid cooling block for enterprise CPUs, GPUs, AI acceleration blades, and high-density server racks.

• Electric Vehicles & Automotive Technology: Ideal for cooling EV traction battery packs, main inverter units, motor drive controllers, and fast-charging power electronics.

• Industrial Power Electronics & Inverters: Functions as high-capacity thermal management bases for Variable Frequency Drives (VFDs), solar power inverters, and high-voltage IGBT modules.

• Medical, Defense & Laser Equipment: Highly suited for medical imaging equipment, high-power surgical lasers, military radar transceivers, and aerospace power supplies.

Outstanding Product Features

• High-Precision CNC Micro-Channel Milling: Executed with precision multi-axis toolpaths to form optimized internal channels and dense fin matrices, dramatically expanding fluid contact area for superior thermal transfer.

• Ultra-Flat Surface Finish for Direct Contact: CNC-milled baseplate contact surfaces achieve micron-level flatness (+/-0.005 mm) and low surface roughness (Ra 0.8 or better) to guarantee zero-gap contact with high-power chips.

• Leak-Proof Structural Integrity: Precision machined for seamless integration with friction stir welding (FSW), vacuum brazing, or O-ring sealing channels, enduring high fluid loop operating pressure without dynamic leaks.

• High Thermal Conductivity Alloys: Machined from high-grade aluminum alloys (such as 6061-T6/6063) or high-purity C1100 copper, balancing lightweight structural strength with exceptional heat conductivity.

• Protective Anti-Oxidization Surface Finishes: Available with clear or black anodizing, electroless nickel plating, or passivated surface treatments to resist corrosion, chemical erosion, and fluid degradation.
