“丹佛斯自豪地制定了MQD规范，为人工智能和高性能计算液冷的可靠性和性能树立了基准。随着热量负载的增加，液冷不再是可选的——它变得必不可少，“ 丹佛斯电力解决方案公司数据中心高级产品经理Chinmay Kulkarni表示。 “我们的 MQD和MQDB 联头提供了强大的性能、安全性和兼容性，使其成为下一代计算托盘冷却系统的理想选择。”

Danfoss Hansen MQD 和 MQDB快速接头采用 304 不锈钢结构以增强耐腐蚀性，并采用 EPDM 密封以增强耐用性。接头配备ISO 11926-3 O型圈凸台、BSPP和软管尾端，以实现应用多样性。快速接头的工作温度范围为-40°C至150°C（-40°F至302°F）。

Danfoss Power Solutions launches MQD and MQDB quick-disconnect couplings for electronics and data center liquid cooling applications

NORDBORG, DENMARK — Danfoss Power Solutions today announced the launch of its Danfoss Hansen? MQD and MQDB series of quick-disconnect couplings, engineered for single-phase water/glycol cooling systems in electronics and data center liquid cooling applications. The MQD hand-mate and MQDB blind-mate couplings feature a compact design ideal for high-density server racks. The couplings are fully interchangeable with MQD couplings from other vendors.

Danfoss MQD and MQDB couplings maximize reliability while enabling high flow rates and simplified installation and maintenance. Every MQD and MQDB component Danfoss produces is helium-leak tested for maximum integrity. Color-coded connectors offer simple identification. The couplings are available in size 02, 03, and 04 (3.3, 4.9, and 6.4-millimeter nominal flow diameters, respectively), with flow rates ranging from 2 to 6.8 liters per minute.

“Danfoss is proud to have shaped the MQD specification, setting benchmarks for reliability and performance in liquid cooling for AI and high-performance computing. As heat loads increase, liquid cooling is no longer optional — it's essential,” said Chinmay Kulkarni, Senior Product Manager, Data Center, Danfoss Power Solutions. “Our MQD and MQDB couplings deliver robust performance, safety, and compatibility, making them the ideal choice for next-generation cooling systems for compute trays.”

Danfoss Hansen MQD and MQDB couplings feature 304 stainless steel construction for corrosion resistance plus EPDM seals for durability. The couplings are offered with ISO 11926-3 O-ring boss, BSPP, and hose tail terminal ends for application versatility. The couplings feature an operating temperature range of -40°C to 150°C (-40°F to 302°F).
