  7. 5. Design and Construction of a Sub-Ambient Direct-on-Chip Liquid Cooling System for Data Center Servers

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Författare :Christopher Cavallin; [2022]
    Nyckelord :Sub-Ambient; Liquid Cooling; Data Center; On-Chip; Direct-to-Chip; Servers;

    Sammanfattning : Sub-ambient direct-on-chip liquid cooling is an emerging technology in the data center industry. The risk of an electrically conductive liquid leaking out to the electrical components and damaging the servers has been the major factor in holding back the use of liquid cooling historically. This technology effectively removes that risk. LÄS MER
