Advanced cooling systems for computers
Climate change is widely regarded as the biggest ongoing issue facing the planet’s inhabitants and many communities are quantifying their “carbon footprint” by calculating the equivalent carbon dioxide emissions of their activities. Reducing energy waste is the first step to reducing carbon emissions. Historically, DUG has pushed the boundaries of energy efficiency by deploying DUG Cool immersion based cooling technology in its data centres worldwide, providing a world-leading efficiency improvement.
Ever decreasing chip lithography, increasing core count, and frequency of operation have pushed the boundaries of energy density in modern logical processor technologies. These advances in processor operation have sparked the need for revolutionary approaches to system support systems, such as cooling, that are both high performance and high efficiency. This presentation outlines some of the various advanced cooling systems being developed for the new generations of computer equipment technologies and their methods of operation, together with impacts on the modern data centre design to enable their implementation in energy dense layouts of the future.
As chief engineer, Lommers leads development of DUG’s High-Performance Computing (HPC) infrastructure and next-generation carbon-free energy resources to commercialise DUG’s global HPCaaS cloud environment, including development of DUG Cool immersion HPC technology, integration of future customer technology needs into the platform, and development and planning of new HPC installations and expansions.
