Leading-Edge Thermal Solutions: MANHICOOL Vacuum Brazed Cold Plates
Specialized in custom AI server liquid cooling​ solutions for high-density GPU clusters including NVIDIA H100/A100. Our HPC thermal management​ systems deliver stable performance under extreme workloads

Solving Thermal Bottlenecks in High-Power Systems

In the era of AI and high-speed computing, standard cooling is no longer enough. Manhang Machinery provides industrial-grade Liquid Cold Plates engineered to handle extreme thermal loads.
By utilizing aerospace-grade Vacuum Brazing, we ensure your equipment operates at peak efficiency with zero risk of leaks.

The MANHICOOL Engineering Difference:

• Maximum Thermal Flux: Using C1100 high-purity red copper, our cold plates deliver thermal conductivity exceeding 390 W/m·K—pulling heat away from critical chips 50% more effectively than traditional soldering methods.
• Precision CNC Micro-channels: We don't just make blocks; we engineer internal flow paths. Our high-density micro-channel designs maximize surface area for heat exchange while maintaining optimal pressure drop.
• Mission-Critical Reliability: Every cold plate undergoes a rigorous 10 Bar pressure test and 100% airtightness inspection. We guarantee zero leakage for sensitive medical and server environments.

• Fast Prototyping: We move from design to physical prototype in days, not weeks.
• Quality-Assured Delivery: Worldwide shipping with robust packaging.

• Q1: Why is Vacuum Brazing superior to traditional soldering or epoxy bonding?
• A: Vacuum brazing occurs in a high-temperature, oxygen-free environment. This creates a 100% metallurgical bond where the filler metal diffuses into the base material. Unlike soldering, it leaves zero flux residue or oxidation, ensuring a cleaner internal channel and a joint that is as strong as the parent metal itself, capable of withstanding extreme pressure and thermal cycling.
• Q2: What materials do you offer for custom cold plates?
  A: We primarily work with C1100 high-purity red copper for maximum thermal flux and 6061/6063 aluminum alloys for lightweight or cost-effective solutions. We also provide surface treatments such as nickel plating (for copper) or chromate conversion and anodizing (for aluminum) to enhance corrosion resistance.
• Q3: Can Manhang help with the thermal design if I only have a heat source layout?
  A: Absolutely. We are your R&D partner. If you provide your heat load, flow rate requirements, and spatial constraints, our engineering team can design the internal CNC micro-channel flow paths and perform thermal simulations to ensure the final product meets your target junction temperatures.
• Q4: How do you ensure the cold plates will not leak in high-value server or medical environments?
  A: Reliability is our baseline. Every unit undergoes a rigorous 10 Bar (145 PSI) pressure test and a 100% airtightness inspection. For mission-critical applications, we also offer Helium Leak Detection (standard sensitivity up to $5\times {10}^{-8}$ mbar·l/s) to guarantee long-term integrity in sensitive environments.
• Q5: What is the typical lead time for a custom prototype?
  A: We pride ourselves on speed. Once the DFM (Design for Manufacturing) is finalized and approved, we can typically deliver a physical prototype within 10 to 15 business days, depending on the complexity of the internal channels and required surface finishes.
• Q6: Are Manhang cold plates compatible with different coolants?
  A: Yes. Our metallurgical joints are highly resistant to chemical degradation. Our cold plates are compatible with Deionized (DI) Water, Ethylene Glycol/Water mixtures (EGW), Propylene Glycol/Water (PGW), and specialized dielectric fluids used in immersion or direct-to-chip cooling.
