The driving force behind Sandia’s adoption of this liquid cooling technology is the projected increase in water and electrical power demands for cooling high-performance computing systems. As computing power continues to grow, the resources required to maintain traditional cooling methods may eventually exceed the capabilities of small towns, posing an unsustainable burden.
Recognizing these challenges, Sandia has partnered with Submer Technologies, a Barcelona-based company specializing in non-conductive liquid cooling solutions, to conduct a comprehensive technical evaluation of their single-phase immersion cooling system. This collaboration aims to assess the reliability of the hardware, as well as the infrastructure support cost and effort, to determine the viability of this revolutionary approach.
The Benefits of Liquid Immersion Cooling
The potential benefits of liquid immersion cooling are numerous and far-reaching. Beyond the significant energy savings, this technology also offers the added advantage of allowing the recovery and utilization of the waste heat generated by the computing systems.
Dave Martinez, the engineering program project lead, envisions building the most energy-efficient data center in the world, where the warmer temperature of the returning liquid can be used to heat adjacent buildings during the winter months and even pre-heat lab water in the summer through heat-exchange processes. This holistic approach to energy management aligns with the growing emphasis on sustainable and eco-friendly practices in the IT industry.
Moreover, the elimination of water-based chilling systems reduces the burden on precious water resources, a crucial consideration in regions where water scarcity is a pressing concern. By adopting this liquid cooling technology, data centers can significantly contribute to the overall conservation of water, a vital resource for many communities.
