MQDB is NVIDIA's second generation liquid cooling quick disconnect coupling standard for the Vera Rubin architecture. As the blind mate variant of the MQD series, it is engineered for cabinet level liquid cooling systems in high density AI data centers, addressing O&M efficiency challenges in large scale deployments.
Compliant with NVIDIA's latest specifications, Netonx MQDB supports blind mating under pressure with tolerance for misalignment, enabling drip free connection/disconnection of node level manifolds. Its planar sealing design ensures low leakage per cycle, while optimized flow dynamics deliver higher flow rates and lower pressure drop.
