Liquid Cooling | 液體冷卻

  • 液體冷卻是什麼?
    液冷技術(Liquid Cooling)顧名思義就是以液體作為熱量傳導機制的散熱方式,市場上常見的有沉浸式液冷和直接液冷兩種方式,前者是以不導電的特殊電子工程液最為熱傳導媒介,將機器直接浸泡在液體裡進行散熱;後者則是利用水管輸送冷卻液體在伺服器中走一圈,透過導熱銅片將熱能帶走降溫,變熱的液體循環到外部後再轉換為冷卻液體或是蒸氣繼續循環利用。

  • 為何需要?

  • 技嘉的特色
    技嘉與合作夥伴提出了多樣性的伺服器冷卻解決方案,從單相式油冷到雙相式浸沒式液冷,到直接水冷,針對不同客戶都能夠提供最符合使用者需求的冷卻方案,在太空中心的案例中就使用了DLC(Direct Liquid Cooling)直接水冷的解決方案,運用超融合基礎架構伺服器(HCI)系列中的H261-Z60。該系統中的最大運算量,相較目前市場上其他高密度伺服器產品,多了兩倍效能,可使數據中心的使用面積減少50%,在有限空間內滿足航太中心的高運算及高速儲存需求,並採用 CoolIT水冷設備,為航太中心設計出絕佳的機房冷卻解決方案。

    GIGABYTE Servers Become Part of the German Aerospace Center’s Data Center
    When the German Aerospace Center (Deutsches Zentrum für Luft- und Raumfahrt, abbreviated as DLR) wanted to expand their data center, they searched for servers that could operate smoothly in an ambient temperature of 40°C without the need for air conditioning. GIGABYTE’s server team provided a solution from its High Density Server product line that combined computing, storage, and connectivity in a single system. The High Density Servers are equipped with liquid-cooling technology to run without a hitch in high-temperature environments, enabling the data center to efficiently process an enormous amount of space-related research data in the limited space available.

    GIGABYTE can now offer various server platforms with liquid cooling technology, such as direct-to-chip liquid cooling (liquid to liquid or liquid to air), one-phase oil immersion or two-phase liquid immersion technologies. Liquid cooling systems can support a greater density of CPUs and GPUs, enabling better compute performance in a given amount of space, as well as helping customers to reduce their power consumption for cooling infrastructure, to achieve a better data center PUE.
