IMK-BMQC SERIES

OCP BMQC SERIES

Main Use: BMQC(Blind Mate Quick Connector)는 OCP(Open Compute Project) 내에서 정의된 액체 냉각 커플링 표준 중 하나입니다. UQDB와 마찬가지로 블라인드 메이트 기능을 제공하지만, 더 높은 수준의 정렬 오차 허용 범위(misalignment tolerance)를 특징으로 합니다

OCP BMQC Coupling Standard Specifications (English)

Application Description

The BMQC (Blind Mate Quick Connector) is an OCP standard designed for use in Open Rack V3 (ORV3) and other high-density liquid cooling applications.

Automated Connection: Enables automatic connection of coolant lines when inserting a server chassis into the rack, ensuring a secure "dry break" interface without manual intervention.
High Misalignment Tolerance: A key feature is its exceptional tolerance for misalignment, allowing up to ±5plus or minus 5
±5
mm radial and
±2.7∘plus or minus 2.7 raised to the composed with power
±2.7∘
angular misalignment, accommodating manufacturing variances in large-scale deployments.
Reliability: Guarantees spill-free operation and is 100% helium-leak tested, crucial for maintaining data center uptime and protecting sensitive IT gear.
