Quick disconnect couplings enable efficient data center liquid cooling

May 8, 2023
Danfoss Power Solutions expands its thermal management portfolio with new universal quick disconnect couplings for efficient data center liquid cooling.

Danfoss Power Solutions has launched a new family of universal quick disconnect couplings for data center liquid cooling applications. The Danfoss Hansen UQD couplings help data center operators meet the thermal management challenges of more powerful chips, denser racks, and heavier workloads through reliable, leak-free, efficient operation.

Engineered for the precision cooling requirements of modern data centers, the company says its UQD couplings are ideal for in-rack liquid cooling applications that use smaller hose lines.

With a 25% higher flow rate than Open Compute Project (OCP) community standards and a low pressure drop, the manufacturer contends the couplings’ best-in-class performance improves system efficiency and reduces in-rack power consumption, enabling data center operators to benefit from long-term cost savings.

The Danfoss UQD couplings also enable strong return on investment through the parts' robust design, long service life, and lower maintenance requirements.

Chinmay Kulkarni, product manager, connectors, Danfoss Power Solutions, commented:

“We’re delighted to launch this great addition to our unparalleled portfolio of thermal management solutions. Based on decades of data center engineering experience, these new UQD couplings complement our broad range of flexible hoses, enabling customers to build reliable and complete thermal management solutions that keep staff and equipment safe, while maximizing computing performance and long-term value.”

Value proposition

Constructed from stainless steel with an EPDM rubber seal, the Danfoss UQD couplings offer high corrosion resistance and broad fluid compatibility.

The couplings are designed to operate at a wider range of temperatures and significantly greater working pressures than the Open Compute Project standard. These capabilities help extend the service life of the couplings and ensure no impact on cooling performance during pressure spikes.

With a flat face dry-break design, the Danfoss UQD couplings are positioned for use with servers and other highly critical applications that demand 100% uptime and leak-free operation.

Even if connections aren’t properly made during assembly or maintenance, the couplings are designed to minimize any risk of leaks that can cause costly damage, downtime, and safety issues. As an additional safety measure, every coupling is helium leak tested.

The Danfoss UQD couplings are available in four sizes, as well as various terminal ends and thread configurations. Two color options are available to minimize the risk of misconnection while reducing assembly and maintenance time.

In addition, the company notes the couplings are engineered to enable quicker and easier maintenance with a push-to-connect design and best-in-class force to connect, both of which allow for convenient, tool-free connection and disconnection with one hand. Learn more about the quick disconnect couplings.

Kulkarni concluded:

“Our new UQD couplings offer a cost-effective and competitive solution for liquid cooling applications. Our thorough validation process, including unique helium leak testing capabilities, gives customers peace of mind when it comes to reliability, consistent cooling, and zero spillage. Compliance with the latest Open Compute Project community standards also means that our couplings are interchangeable with products from other vendors, giving customers the flexibility to select the best solution for their needs.”
