數(shù)據(jù)中心浸沒式液冷技術(shù)淺析
數(shù)字化進(jìn)程的加速和“雙碳"承諾都使得綠色數(shù)據(jù)中心建設(shè)成為大勢所趨,浸沒式液冷憑借節(jié)能環(huán)保、安全低耗等核心優(yōu)勢已然具備成為未來重要冷卻技術(shù)的潛質(zhì),但全面推廣仍存較多阻力。
浸沒式液冷技術(shù)作為一種新型制冷方案,相較于空氣冷卻和冷板式間接液冷存在著顯著優(yōu)勢。本文從部署原理、相變機(jī)制、冷卻液類型等維度對當(dāng)下主流的浸沒式液冷技術(shù)展開了詳細(xì)論述,并對其未來發(fā)展提出了推廣建議。
一、 引言
近年來,人工智能、云計算、物聯(lián)網(wǎng)、區(qū)塊鏈等技術(shù)的不斷進(jìn)步,對電子信息設(shè)備的性能和集成度提出了越來越高的要求,隨之而來的高熱密度和巨額能耗等問題對數(shù)據(jù)中心制冷技術(shù)也提出了更高的挑戰(zhàn),具體表現(xiàn)在以下幾個方面:
1.底層基礎(chǔ)設(shè)施性能的不斷提升帶來數(shù)據(jù)中心能耗的顯著增加。目前,高性能計算處理器單機(jī)熱負(fù)荷已達(dá)到一般處理器的2倍以上,單機(jī)柜整體功耗已經(jīng)翻倍,且數(shù)據(jù)中心的體量亦在與日俱增,高能耗已經(jīng)成為一個亟待解決的問題。
2.電子器件功率和封裝密度引發(fā)熱流密度的急劇提升。據(jù)統(tǒng)計,失效的電子器件中有55%是由于溫度過高或不均造成的,面對高功率和高封裝帶來的的冷卻需求。
3.高效制冷成為數(shù)據(jù)中心轉(zhuǎn)型的重要環(huán)節(jié)。冷卻能耗占總能耗的40%左右,且運(yùn)行過程中溫度的不斷升高會造成巨大隱患,因此提高制冷效率是高能效、高密度配置轉(zhuǎn)型的有效手段。
4.國家已經(jīng)頒布了一系列政策,旨在引導(dǎo)數(shù)據(jù)中心向綠色、高效的方向發(fā)展。如2020年國家發(fā)改委頒布的《關(guān)于加快構(gòu)建全國一體化大數(shù)據(jù)中心協(xié)同創(chuàng)新體系的指導(dǎo)意見》中提到,2025年前大型數(shù)據(jù)中心PUE<1.3。這一舉措極大推動了冷卻技術(shù)的升級。
目前,數(shù)據(jù)中心主要制冷技術(shù)包括風(fēng)冷、液冷、蒸發(fā)冷卻和自然冷卻,其中風(fēng)冷技術(shù)雖然憑借其低成本、易維護(hù)等特性成為當(dāng)前主要冷卻方式,但也存在其局限性:
1.采用集中制冷模式冷卻機(jī)架內(nèi)所有的電子器件,加之空氣的換熱系數(shù)較低,導(dǎo)致制冷效率低下、冷卻能耗過高。此外,冷熱空氣換熱不均勻會形成局部熱點(diǎn),而為消除這些熱點(diǎn)又會造成過度冷卻、額外耗能。
2.需要大量的空間來放置空調(diào)、機(jī)架和送風(fēng)通道,導(dǎo)致占用空間大、部署密度低。
3.常年不間斷的運(yùn)行模式,造成天然冷源的浪費(fèi),不利于節(jié)能環(huán)保。
傳統(tǒng)風(fēng)冷模式逐漸遇到瓶頸,數(shù)據(jù)中心制冷技術(shù)向精細(xì)化轉(zhuǎn)變已成必然趨勢,在此背景下,液冷技術(shù)以其高效綠色的特點(diǎn)引起行業(yè)的普遍關(guān)注。
二、液冷技術(shù)簡介及對比
液冷是指使用液體取代空氣作為冷媒,直接導(dǎo)向熱源帶走熱量的制冷技術(shù)。相較于傳統(tǒng)風(fēng)冷,液冷具有顯著的優(yōu)勢:
1.液體的比熱容遠(yuǎn)高于空氣,可以吸收大量熱而保持溫度在較小范圍內(nèi)波動,有效抑制溫度驟升,在一定程度上允許超頻工作,提升了集成度。
2.風(fēng)冷制冷方式被取代,能耗迅速降低、電費(fèi)支出減少,且?guī)缀趺獬凉穸取⒒覊m和振動影響,設(shè)備可靠性提升,硬件維護(hù)支出減少,同時減少了風(fēng)扇的振動和噪音,基本可達(dá)到“靜音機(jī)房"效果。
根據(jù)冷卻液是否與IT設(shè)備直接接觸,可將液冷技術(shù)分為間接液冷和直接液冷。間接液冷是指發(fā)熱器件與液體冷媒之間沒有直接接觸的制冷方式,冷板式液冷是間接液冷的典型部署方式。而直接液冷采用冷卻液,通過冷卻液與發(fā)熱元件直接接觸將熱量循環(huán)帶走,其中代表性的就是浸沒式液冷。本文從支持性能和綜合性能兩個方面進(jìn)行了空氣冷卻、冷板式間接液冷和浸沒式直接液冷的對比,詳見表1、表2。

冷板間接也冷與浸沒式直接液冷的性能綜合對比
可以看出,冷板式液冷只有大功耗發(fā)熱元件CPU)采用液冷散熱,仍需保留部分風(fēng)冷裝置,且冷卻液沒有與電子元件直接接觸,散熱性能、空間利用率和節(jié)能降噪效果都不及浸沒式液冷,故本文接下來針對浸沒式液冷技術(shù)進(jìn)行闡述。
三、浸沒式液冷解決方案
浸沒式液冷以液體作為傳熱介質(zhì),將發(fā)熱電子元件直接浸沒于冷卻液中,通過冷卻液與電子元件直接接觸進(jìn)行熱交換帶走熱量,是一種新型高效、綠色節(jié)能的數(shù)據(jù)中心制冷解決方案。
根據(jù)冷卻液是否發(fā)生相變,浸沒式液冷分為相變浸沒式液冷和單相浸沒式液冷。相變浸沒式液冷利用冷卻液沸點(diǎn)低可發(fā)生沸騰相變的特性,在沸騰過程中利用潛熱吸收熱量來達(dá)到散熱的效果。而單相浸沒式液冷技術(shù)是指將電子設(shè)備浸沒在冷卻液中進(jìn)行直接冷卻,形成封閉的導(dǎo)熱回路。相變浸沒式液冷主要由冷卻液、密封腔體、芯片散熱膜模塊、冷卻模塊和室外冷源組成,包括服務(wù)器冷卻回路和冷凝冷卻回路兩個循環(huán)回路。
如圖1所示,液冷機(jī)箱內(nèi)裝有低沸點(diǎn)的冷卻介質(zhì),電子設(shè)備浸泡在密封的柜體中,電子元件工作時產(chǎn)生的熱量會使得冷卻液溫度升高,當(dāng)溫度超過飽和溫度時,冷卻液受熱沸騰形成蒸汽泡逃逸至機(jī)柜頂部的蒸汽區(qū),即在罐內(nèi)形成氣相區(qū)域,形成的蒸汽被外循環(huán)回路的冷凝管換熱器再次冷凝成液體滴落到機(jī)柜中,冷凝管中的水等其他冷卻介質(zhì)與冷卻液換熱后,由泵輸入干燥塔,與空氣進(jìn)行冷卻換熱,通過循環(huán)流動將熱量傳遞出去。中科曙光硅立方液冷相變冷卻計算機(jī)采用的就是浸沒相變液冷技術(shù),以氟化液作為冷媒,實(shí)現(xiàn)能效比PUE突破性降至1.04,節(jié)能,此外還將CPU主頻提高15-20%,單機(jī)柜功率密度提升至160kW,部署密度也達(dá)到水平。
