Refrigerated cooling of microprocessors with micro-evaporation heat sinks: new developments and energy conservation prospects for green data centers.

Auteurs : THOME J. R., BRUCH A.

Résumé

Cooling of data center servers and blade centers is undergoing a vast technological change away from air-cooling technology with its large refrigeration loads towards more energy efficient means. One of the front-runner replacement technologies under development is the use of micro-evaporator heat sinks placed directly on the microprocessor and memory chips. In such a two-phase cooling system, the refrigerant is circulated in multi-micro-channels either by a liquid pump (which allows free cooling nearly all year at many locations as heat is rejected at 50-65°C) or by a compressor (which rejects the heat at about 90°C). In both cases, the heat can potentially be used for heating of the building, building utilities (hot water) and other nearby process/industrial applications. The key component of all this technology is the micro-evaporator. This paper describes the basic overall design of such systems and provides a specific description of micro-evaporators and the status of their thermal design and simulation for use in "green data centers" with a greatly reduced CO2 footprint.
