Danfoss Hansen® Universal Quick Disconnect Blind-Mate (UQDB)
UQDB and OCP (Open Compute Project) jointly established industry standards for liquid cooling thermal management, focusing on blind-mate scenarios.
OCP UQDB Standard Self-alignment（Radial compensation 1 mm） Push-to-connect Flat-face dry break
100% helium-leak testing Terminal ends are ORB
100% helium-leak testing Terminal ends are ORB
Blind-connection Automatic alignment
“Blind-connection” thanks to self- alignment feature with radial compensation of 1 mm
High flow rate, no overflow
Improve system efficiency, reduce pressure drop losses, and be more friendly to data center thermal management.
Surface separation reduces spillage
The flat surface disconnects the street, reducing the risk of exposure when connecting/disconnecting.
Product Overview
Danfoss Hansen UQDB（Blind-Mate）Provide the same size range as UQD (-02 / -04 / -06 / -08),but for connections within cabinets that are invisible and intangible, incorporate self-alignment to enhance operability and success rate.
