PŘEHLED PRODUKTU

Přehled produktu

Product Overview

Engineered specifically for next-generation 1000W+ AI accelerators, GPU clusters, and high-heat-flux ASIC processors, the Custom Skived Fin Microchannel Pure Copper Liquid Cold Plate (Model: LC-CU-01) sets the benchmark for extreme thermal dissipation. Utilizing monolithic skived fin machining from ultra-pure oxygen-free copper (C11000 / Cu-ETP), this cold plate eliminates interface thermal resistance between fins and baseplate. Coupled with hermetic vacuum brazing and mirror-polished chip contact zones, it delivers industry-leading low thermal impedance (< 0.008 °C/W) while maintaining zero leakage under rigorous operating pressures.

Core Engineering & Manufacturing Advantages

  • Monolithic Integral Skived Structure: Skived directly from continuous copper billets, achieving 100% metallurgical continuity without thermal bonding pastes or solder joints, maximizing conductive heat transfer into fluid streams.
  • Ultra-Dense Microchannel Geometry: Enables fin pitches as tight as 0.2mm with aspect ratios exceeding 15:1, yielding up to 600% more active wetted surface area compared to conventional CNC-slotted plates.
  • Flux-Free Vacuum Brazed Enclosure: High-vacuum brazing at 10⁻⁴ Pa ensures ultra-clean internal fluid circuits without chemical flux residue, preventing coolant fouling and galvanic corrosion in closed-loop server racks.
  • Direct Die Mirror Finishing: Multi-axis ultra-precision fly-cutting achieves Ra ≤ 0.2 μm surface roughness and 0.015 mm flatness, dramatically reducing thermal grease/TIM bond line thickness.
  • Agile Fast-Turn Prototyping: Dedicated prototype engineering cells provide full DFM thermal simulations within 24 hours and custom physical prototypes in 7 to 10 working days.

Frequently Asked Questions (FAQs)

Q1: Can Altus Precision customize microchannel copper cold plates for proprietary GPU/ASIC footprints?

A: Yes. More than 85% of our liquid cooling production is customized build-to-print. Customers provide 3D CAD models (STEP/IGES) and thermal boundary requirements; our engineering team conducts CFD flow and thermal simulations to optimize channel layout and inlet/outlet port locations.

Q2: How do you guarantee zero leakage in high-density server rack environments?

A: 100% of manufactured cold plates undergo helium mass spectrometer leak testing with a rejection threshold of ≤ 1×10−9 mbar·L/s, followed by hydrostatic proof pressure testing up to 3.5 MPa. Full FAI inspection reports and leak test certificates are included with each lot.

Q3: What coolants and quick disconnect fittings are supported?

A: With electroless nickel plating, the cold plate is fully compatible with deionized water, ethylene/propylene glycol-water solutions (EGW/PGW), and synthetic dielectric liquids. Fittings support standard G1/4", G3/8", NPT threads, quick-disconnect couplers (QDC), or custom stainless steel brazed barb tubes.
