Digitalization means a massive and ongoing escalation in online activity and data flow. Ever-increasing computing power comes with a growing need for data protection and vast storage capacity. The energy involved means liquid cooling is no longer a nice option but a necessity. Non-spill connection technology allows hot swapping (changing blades and racks without stopping the installation), making maintenance easier and protecting IT systems.
Perfectly integrated from the start, Stäubli quick-release couplings guarantee operational continuity and high availability of installations. Completely reliable and non-drip, our connection solutions increase the safety and performance of installations: computer and electronic systems, supercomputers, data-center water cooling, telecommunications, broadcasting and semiconductors.
The high availability of data centers is essential.
How can you guarantee it?
The answer is in our new white paper:
Liquid cooling is now the most adapted solution where the air cooling can be powerful enough. For example, in the case of processors exceeding 250 W, air cooling is no longer enough.
In addition to boosting efficiency, liquid cooling saves space and reduces energy use.
Different technologies are today available to integrate liquid cooling in your systems. Stäubli offers its expertise and its solutions for each of them.
Disover the liquid cooling technologies below.
Cold-plate liquid cooling is currently the most common technology. It removes heat by circulating water in the blades of an electronic rack.
Cold-plate technology comprises the greatest number of quick release couplings. In the case of supercomputers or data centres, for example, a rack can contain up to 48 blades and each blade requires two couplings. The diameter of the couplings is from 3 to 8 mm.
The liquid circulates in the plates to cool the components. Warmer liquid leaves the blade to rejoin the circuit and be cooled. Each blade may comprise several cold plates. 2 quick couplings are required for each blade in this context.
With single-phase immersion technology, the temperature of the electronic components to be cooled is managed by immersing the components in non-conducting fluid inside a tank.
This technology requires few quick release couplings, but the diameters are larger: 20 to 25 mm.
“Cold” coolant enters the tank, the liquid absorbs heat from the components and the liquid leaves the tank to be cooled. Quick couplings are necessary at the ...
Two-phase immersion consists of immersing the components in a non-conducting liquid that evaporates when it comes into contact with the component.
This technology requires two quick release couplings: one on the cold water side, and another on the warm water side.
In this case, 2 sizes of quick couplings must be provided. One on the inlet of cold liquid coolant, and another on the outlet of warm two-phase coolant.
The liquid coolant, heated by the component, evaporates; the boiling of the liquid cools the component. The water in the circuit cools the gas coolant that condenses. The warm water leaves the condenser to evacuate the heat and be cooled.
