Electrical circuits encased in fluid may reshape data-center design
Researchers at Sandia are testing a new method for cooling computer servers that could almost entirely eliminate the need for the power-hungry fans and chillers used in conventional cooling systems.
By submerging all parts of the computing servers in a liquid coolant that doesn’t conduct electricity, 100% of the generated heat can be captured, almost entirely eliminating the need for the power-hungry fans and chillers used in conventional cooling systems. Sandia’s forward-thinking approach arises from projections that the increasing water and electrical power demands for cooling in high-performance computing eventually will exceed the resources of small towns and become an unsupportable burden. In 2020, Submer, in collaboration with Intel Corp., introduced the idea of a liquid coolant that would bathe all components of a computing system to provide even cooling and allow higher operating temperatures.
