Liquid Cooling Systems | Reliable Quick Disconnects
Liquid cooling systems depend on reliable quick disconnect connectors to support efficient thermal management in AI data centers, high-performance computing, EV charging infrastructure, and energy storage systems. Amphenol Industrial Operations offers a broad portfolio of liquid cooling quick disconnect connectors engineered to support serviceability, sealing performance, and flexible cooling architecture design.
The portfolio includes the UQD, UQDB, UQD/UQDB Rev 2.0, BMQC, LQC, MQD, and SHQD series. These connector families are designed to support modern cooling loops across server racks, coolant distribution units, source lines, manifolds, blind-mate interfaces, and compact tray-level thermal systems.
As computing densities continue to rise, liquid cooling systems are becoming increasingly important for removing heat from AI servers, high-performance computing platforms, and other advanced power electronics. Quick disconnect liquid cooling connectors support these systems by enabling efficient coolant transfer, streamlined maintenance, and modular system expansion without sacrificing sealing integrity.
Amphenol Industrial Operations supports a wide range of thermal management architectures with connector solutions for compact server trays, blind-mate rack interfaces, high-flow CDU infrastructure, and source-line distribution. Several product families align with Open Compute Project standards, including the OCP UQD listing and the OCP BMQC listing.
UQD Series Quick Disconnect Connectors
The UQD Series provides standardized quick disconnect performance for liquid cooling systems that require fast manual engagement and reliable coolant containment. These connectors are well suited for server-level cooling loops and other modular thermal management applications where service access and connection speed are important. UQD connectors support multiple sizes and configuration options, helping engineers integrate cooling connections across a broad range of data center and industrial thermal architectures.
UQDB Blind Mate Quick Disconnect Connectors
The UQDB Series is designed for blind-mate liquid cooling applications where connectors must align and connect during system insertion. This architecture helps simplify rack-level installation and maintenance in high-density server environments where direct manual connection may be limited. UQDB connectors support improved serviceability while maintaining secure fluid transfer across critical cooling interfaces.
UQD / UQDB Rev 2.0 Liquid Cooling Connectors
The UQD/UQDB Rev 2.0 platform expands the original quick disconnect architecture with updated geometry, improved flow capability, and broader interoperability across modern data center liquid cooling systems. Rev 2.0 helps support evolving OCP-aligned cooling designs where improved performance and more defined interface control are increasingly important. For designers building next-generation rack and manifold systems, Rev 2.0 offers an updated option for scalable and service-friendly cooling infrastructure.
BMQC Blind Mate Quick Connectors
The BMQC Series is engineered for blind-mate rack applications that must tolerate installation misalignment while maintaining reliable coolant transfer. These connectors are especially relevant for Open Rack V3 style architectures and other rack-level cooling systems where fast, repeatable blind-mate performance is critical. BMQC connectors support simplified installation and robust mechanical performance in high-density liquid cooled rack environments.
LQC Large Flow Quick Disconnect Connectors
The LQC Series is designed for liquid cooling systems that require larger flow capacity and secure mechanical engagement. With a large nominal flow path and screw-to-connect coupling style, LQC connectors are well suited for cold plates, manifold interfaces, and other higher-flow thermal management applications. LQC supports reliable connection integrity where vibration resistance and controlled engagement are important design considerations.
MQD Multi Quick Disconnect Connectors
The MQD Series is tailored for compact liquid cooling systems where available space is limited. Its smaller footprint helps support dense server tray layouts and other confined cooling installations without sacrificing reliable fluid connection performance. MQD connectors are a strong fit for designers who need compact geometry, serviceability, and cooling performance in the same connector platform.
SHQD Source-Line Quick Disconnect Connectors
The SHQD Series is designed for source-line liquid cooling connections where higher flow capacity and enhanced safety are critical. These connectors support larger coolant lines and are well suited for CDU infrastructure and facility-level coolant distribution within advanced liquid cooling systems. SHQD helps address demanding source-line applications that require dependable coolant transfer, serviceability, and secure connection performance.
