Data center liquid cooling
Liquid Cooling Quick Disconnects
Define the interface. Review the complete connection.
Discuss UQD / UQDB and other liquid cooling connection requirements, from plug-and-socket selection to an approved alternative supply route.
UQD means Universal Quick Disconnect for hand-mated connections; UQDB means Universal Quick Disconnect Blind-Mate. Specify the required interface and counterpart. Supply availability and compatibility are confirmed for the selected pair.
Specification review
Define what your system needs.
Share what is known. The remaining details can be confirmed during review.
Compatibility, performance and supply availability are confirmed for the selected connector pair and application. No blanket cross-brand interchangeability is implied.
| Parameter | What to specify |
|---|---|
| Interface & size | Required standard and revision, nominal flow size, plug / socket and mating component part number. |
| Connection style | Hand-mated or blind-mate requirements, available space, alignment and mounting constraints. |
| Flow performance | Target flow, coolant and temperature; available Cv data or pressure-drop curves for the selected connection. |
| Pressure & temperature | Working and connection / disconnection conditions, including any pressure differential and temperature limits. |
| Wetted materials & seals | Body, valve and seal materials reviewed against the exact coolant formulation and concentration. |
| Disconnect performance | Permitted spillage and air inclusion, shut-off requirements and acceptance test method. |
| Connection life | Required mating cycles and the corresponding operating and verification conditions. |
| End termination | Hose attachment or thread standard, size, sealing method, dimensions and orientation. |
| Brand & compatibility | Designated brands and part numbers, mating-pair requirements and evidence needed to approve an alternative. |
Configuration & delivery
Review the conditions that matter.
Match both halves
Review the plug and socket as a pair. Similar appearance or nominal size alone is not sufficient to confirm interchangeability.
Review the fluid path
Consider the required flow and pressure-drop allowance alongside body materials, seals and the coolant formulation.
Qualify an alternative
Send the incumbent part numbers and fixed requirements. Define the compatibility evidence and sample checks needed for an approved second source.
Applications
Designed into the cooling loop.
Serviceable rack connections
Specify accessible, hand-mated connections together with the space needed for connection and disconnection.
Equipment & server interfaces
Match the connector envelope, flow allowance and coolant requirements of the equipment.
Blind-mate requirements
For UQDB or other blind-mate projects, share alignment, mounting, engagement and mating-interface details.
Review your mating parts as a pair.
Share the exact counterpart, applicable interface specification and revision, and your required compatibility evidence.
