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?
液體相較於傳統空氣冷卻熱傳導方面更有效率,故常常使用在一些高速運作發熱量較高的機器上,尤其是資料中心、或是進行大量運算的人工智慧伺服器當中。相較於空冷需要風扇協助散熱,去除風扇模組和省卻熱流設計得到的空間提升,便可大幅度的增加CPU、GPU密度,在有限空間中增加更多的運算效能,降低能耗的同時就表示可以得到更好的PUE值

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.
