Experimental evaluation of a controlled hybrid two-phase multi-microchannel cooling and heat recovery system driven by liquid pump and vapor compressor / Duan Wu in International journal of refrigeration, Vol. 36 N° 2 (N° spécial) (Mars 2013) 

Public ISBD [article]  in International journal of refrigeration > Vol. 36 N° 2 (N° spécial) (Mars 2013) . - pp. 375–389 Titre : Experimental evaluation of a controlled hybrid two-phase multi-microchannel cooling and heat recovery system driven by liquid pump and vapor compressor Titre original : Evaluation expérimentale d'un système hybride et régulé de refroidissement diphasique à microcanaux et de récupération de chaleur entraîné par une pompe et un compresseur de vapeur Type de document : texte imprimé Auteurs : Duan Wu, Auteur ; Jackson Braz Marcinichen, Auteur ; John Richard Thome, Auteur Année de publication : 2013 Article en page(s) : pp. 375–389 Note générale : Refrigeration Langues : Anglais (eng) Mots-clés : Data  center;  Chip;  Cooling;  Heat  recovery;  Two-phase  flow;  Controller Résumé : The energy use in data centers is on an accelerating rise due to both demand and technological limitations. Today, the most widely used cooling strategy for data centers is refrigerated air-cooling. Unfortunately, air-cooling presents phenomenally low efficiencies. Therefore green computing paradigms are needed to improve energy efficiency by several orders of magnitude and allow a continued chip scaling for tackling the energy crisis in future-generation data centers. A promising solution would be implementing direct on-chip two-phase cooling technology, which not only improves the heat removal efficiency but also permits the reuse of waste heat since the two-phase coolant can cool CPUs effectively at 60 °C. In the present work a specific cooling cycle using micro-evaporation technology has been experimentally evaluated considering different aspects such as cooling cycle and energy recovery efficiencies and controllability. In resume, this novel cycle shows strong competence in energy usage, heat recovery and controllability towards green data center.
