mmersion cooling is a base technology which
I fully captures all thermal energy in liquid . The Asperitas innovative concept of Immersed Computing focuses on the integration of IT equipment with immersion cooling . This allows the deployment of immersion cooling with warm water cooling and high reliability of IT equipment because it also includes the optimisation of IT equipment for this type of technology . However , to address global data centre challenges regarding sustainability , efficiency and flexibility , immersion cooling goes far beyond just the technology . It embraces the most efficient model for operating IT equipment , reducing the energy footprint of said equipment by eliminating overhead energy . Moreover , the ability of the liquid to capture all the IT energy combined with warm water cooling enables solutions ready for heat reuse .
Immersion cooling technology actively helps data centre operators fulfil their sustainability goals , as using this approach makes it possible to reduce the energy footprint by up to 50 %. Presently , data centres are consuming around 4 % of the global energy supply , using energy for IT and cooling . Each data centre consistently churns out warm air which is too low in temperature to efficiently distribute and transport . Changing the common cooling medium ( air ) for the much more efficient medium ( liquid ) is changing everything for data centres . It addresses the global challenges , preparing data centres for a future of high density and performance hardware , facility efficiency anywhere and sustainability .
Total immersion cooling ensures no oxygen touches the IT components , thus preventing oxidation . Thermal shock is greatly reduced due to the high heat capacity of liquid . The immersed environment only has minor temperature fluctuations , greatly reducing thermal expansion stress on micro electronics . These factors eliminate the root cause for most of the physical degradation of micro electronics over time . All of the Asperitas data centre immersion cooling solutions are driven by natural convection to circulate the dielectric liquid for heat transfer . Consequently , pumps are not needed for this purpose , resulting in solutions whereby moving mechanical components and energy overheads are not present .
By making the energy available for reuse for heating , Asperitas reduces the footprint of a third-party with the heat demand , enabling the transformation of data centres from heavy energy
TO ADDRESS GLOBAL DATA CENTRE CHALLENGES REGARDING SUSTAINABILITY , EFFICIENCY AND FLEXIBILITY , IMMERSION COOLING GOES FAR BEYOND JUST THE TECHNOLOGY .
consumers into energy suppliers and contributors to the Circular Economy ( 100 % energy reuse ready ).
The key goal for immersion cooling is to enable sustainable and high-performing data centres that facilitate all emerging digital technologies , anywhere and on any scale . The real opportunity is to enable data centres to run with a PUE of 1.04 anywhere and add value by optimal IT performance and heat delivery . Asperitas believes in thinking differently , with responsibility towards the future energy footprint and therefore contributing to a better world . ◊
