    Location and QD Specification

    Liquid Cooling Quick Disconnects – Which Ones, Where and Why

    Download Tech Guide

    Overview

    Because liquid cooling is now a necessity in a growing range of applications, it is time to overcome the traditional concerns about the proximity of liquid with expensive and sensitive electronics. Quick disconnects (QDs) — in this case, non-spill or “dry break” connectors — are vital in creating reliable cooling systems and supporting the modularity for serviceability that these applications demand. 

    To some degree, it doesn’t matter if a design engineer is specifying QDs for high-performance computing, AI data centers, EV fast-charging stations, medical equipment, telecommunications systems, lasers or green energy equipment. What is important is specifying the right size and style of fluid connector for the liquid cooling system. 

    “Location and QD Specification: Liquid Cooling Quick Disconnects – Which Ones, Where and Why” covers the three main areas of where to site fluid connectors and how the size and style will vary depending upon how close in proximity they are to sensitive electronics. While referring to a compute system, the concepts are applicable to most applications which include manifolds, are space constrained and/or have the need for modularity. 

    The basics of flow coefficients and pressure drop are covered and the challenges of connections in tight spaces is discussed. A reference table lists nominal flow sizes and Cv.  Additionally, this tech guide highlights a few custom engineered solutions that CPC has developed in collaboration with customers in order to address configuration or space challenges.

    Chemical Compatibility in Liquid Cooling Solutions

    Chemical compatibility within a liquid cooling loop helps the system performs to specification. With ongoing advances in fluid options and materials, it is important to think holistically when specifying coolant and components, taking into consideration potential interactions.

    Fluidic Flow Considerations for Liquid Cooling

    Proper flow within a liquid cooling system helps ensure it performs to specification. While flow for liquid cooling thermal management seems simple enough, there is a lot to consider including: cooling load, Cv, specific gravity, and coolant selection.
