Increasing power densities, compact geometries, and stricter environmental regulations are driving the need for efficient, low-GWP cooling solutions. At CERN, boiling carbon dioxide is already well-established for low-temperature detector cooling. However, above its critical temperature (31°C), sCO2 becomes a highly attractive option for electronics operating in the warm regime. This poster presents the newly built test rig to characterize heat transfer with sCO2.
