Integrated Blind-Mate Connector for Rack-Level Liquid Cooling
Product Detail
The primary engineering hurdle in rack assembly is spatial geometric alignment. In standard 42U racks, cumulative tolerances between compute nodes, rails, and backplanes can exceed ±2.0mm. Yokey’s advanced connector architecture utilizes a "Floating Compensation" design, transitioning from rigid coupling to flexible adaptation. This ensures that even under severe off-center loads, the sealing surfaces maintain constant preload, preventing instantaneous internal leaks or valve jamming.
Key Features
Omni-Directional Radial Compensation (±2.0mm): Integrated floating sleeve mechanisms allow for a radial offset tolerance of up to ±2.0mm. This compensation capability significantly reduces the risk of mechanical jamming during node insertion in high-density rack environments.
"Flat-Face" Zero-Drip Standard (< 0.03 mL): Utilizing flat-face paired valve technology, we eliminate internal "Dead Space." Disconnection leakage is strictly controlled under 0.03 mL, preventing coolant accumulation on sensitive "Golden Fingers" and eliminating electrolytic sediment risks.
CFD-Optimized Flow Efficiency (High Cv): Through advanced Computational Fluid Dynamics (CFD), we’ve engineered streamlined valve flaps and convergent-divergent flow paths. This optimization reduces parasitic pumping power by 10-15%, directly improving rack-level PUE.
Hard-Anodized + Nano-PTFE Infusion Coating: To prevent "Galling" wear in unlubricated environments, our connectors feature a composite PTFE-infused coating. This reduces the friction coefficient by 60%, ensuring stable performance over 5,000 to 10,000+ coupling cycles.
Micron-Scale CNC Precision (±0.015mm): Manufactured to aerospace-grade standards, our precision-machined valve cores and shells ensure perfect interfacial fit and dynamic sealing integrity under high-pressure thermal cycles.
Applications
AI & HPC Rack Architectures: The primary interface for GB200 and high-density liquid-cooled server racks requiring blind-mate node coupling. HPC Compute Nodes & Blade Servers: Providing robust, maintenance-free connectivity for hot-swappable computing units. Manifold Backplane Integration: Ideal for fixed manifold backplanes in 42U racks where physical alignment visibility is restricted. Edge AI Infrastructure: Reliable, spill-free connectivity for compact liquid cooling systems in uncontrolled edge environments.
Technical Capabilities & Engineering Support
Floating Architecture Engineering: We specialize in omni-directional floating mechanics that utilize dynamic elastomer damping to absorb 3D spatial tolerances. Flow-Path Simulation (CFD): Yokey provides custom flow-path modeling to help customers optimize system-level pressure drops and pumping efficiency. Agile Prototyping: Utilizing our precision machining DNA, we offer a 14-day rapid prototyping mechanism for custom UQD or blind-mate interface requirements. TCO & Maintenance-Free Lifecycle: By extending coupling life to 10,000 cycles, we significantly lower the Total Cost of Ownership (TCO) compared to standard commercial-grade connectors.
Conclusion
Transitioning from "Blind Insertion" to "Certain Connection" is the final frontier for rack-level liquid cooling safety. Yokey’s Blind-Mate Connectors serve as the robust fortress for your power and signal integrity, ensuring that every coupling is a zero-failure event in the AI era.
