200kW + AI Racks Hloov Cov Khoom Siv Hluav Taws Xob Cov Khoom Siv Hluav Taws Xob
AI Data Center Liquid Cooling: 2025 Kev Lag Luam Status thiab Kev Loj Hlob Outlook
Cov neeg ua haujlwm Hyperscale tab tom kho dua tshiab tag nrho cov neeg rau zaub mov racks nyob ib puag ncig cov kua txias. Kev hloov pauv tsis yog kev sim ua haujlwm ntxiv lawm - nws yog tus qauv kev yuav khoom rau tom ntej - tiam AI infrastructure. Ntawm no yog qhov chaw lag luam sawv hauv 2025.
Vim li cas AI Workloads yuam kev hloov ntawm huab cua mus rau kua
AI kev cob qhia pawg tsim kom muaj cua sov uas cua txias tsis tuaj yeem tshem tawm lub cev. Ib qho NVIDIA GB200 NVL72 khib dissipates txog 132 kW. Txheem huab cua tuav saum toj kawg nkaus nyob ib ncig ntawm 30-40 kW ib lub khib ua ntej yuav tsum muaj ntau qhov chaw hauv pem teb thiab lub zog kiv cua. Cov lej yuam kev sib txawv.
Cov kua txias tshem tawm 3,000 npaug ntawm cov cua sov hauv ib chav tsev ntau dua li cua. Qhov no tsis yog ib qho kev nyiam engineering - nws yog ib qho kev txwv ntawm lub cev. Txhua tus neeg muab kev pabcuam huab loj tau tshaj tawm cov phiaj xwm xa tawm uas xav tias ua kua -cov khib nyiab txias rau AI kev cob qhia pawg los ntawm 2026.
Kev Ua Lag Luam Loj Tshaj Tawm rau AI Ua Kua Dej Txias
Lub lag luam ua kua txias rau cov ntaub ntawv chawyog loj hlob nyob rau hauv ib tug unprecedented tus nqi. Raws li kev lag luam kwv yees tau tshaj tawm los ntawm Grand View Research, lub ntiaj teb cov ntaub ntawv chaw ua kua txias ua lag luam mus txog kwv yees li $ 4.5 nphom hauv xyoo 2024 thiab tau npaj kom nthuav dav ntawm kev loj hlob txhua xyoo ntau tshaj 24% txog 2030.
- 2024 tus nqi lag luam: ~ $ 4.5 billion (cov ntaub ntawv chaw ua kua cua txias ntu)
- Kwv yees 2030 tus nqi: tshaj $ 16 nphom
- CAGR: 24% + (2024-2030)
- AI neeg rau zaub mov sib koom ntawm cov kua txias xav tau: kwv yees 60% + los ntawm 2026
Cov duab no qhia txog cov khoom siv cua txias ncaj qha - cov phaj txias, CDUs, manifolds, thiab cov raj uas txuas rau lawv. Cov khoom siv thermal tswj ntu ntu, uas suav nrog cov kav hlau tsis muaj cua txias, sawv cev kwv yees li 25% ntawm tag nrho.
Direct-rau-Chip vs Immersion Cooling Adoption
Ob lub tshuab ua kua cua txias ua tus thawj lub khw tam sim no. Txhua qhov sib txawv ntawm kev xa tawm scenarios.
| Dimension | Direct-rau-Chip (Cold Phaj) | Dej Txias |
| Hom Coolant | Glycol- dej los yog dej ntshiab | Dielectric kua (synthetic/PAO) |
| Coolant ntim rau ib lub khib | 10-30 liters | 800-1,500 litres |
| Txias efficiency | 40-60% kev txuag hluav taws xob vs huab cua | 50-70% kev txuag hluav taws xob vs huab cua |
| Retrofitting cov chaw uas twb muaj lawm | Ua tau nrog CDU kev koom ua ke | Kev tsim kho lub cev loj yuav tsum tau ua |
| theem kev saws me nyuam | Mainstream - tus qauv hyperscale | Thaum ntxov - niche thiab pilot |
| Tej kev siv | AI kev cob qhia pawg, HPC | Crypto mining, ntug, tshwj xeeb HPC |
Direct-rau-chip dominates vim nws integrates nrog cov neeg rau zaub mov uas twb muaj lawm daim ntawv foos. Immersion yuav tsum tau tsim tshwj xeeb cov servers uas tsis muaj huab cua -cov khoom ua kom txias, uas txwv tsis pub nws cov khoom siv sib raug zoo. Feem ntau qhov kev xa tawm hyperscale nyob rau hauv 2025 siv ncaj qha - mus rau -chip nrog lub coolant faib chav tsev (CDU) regulating ntws thiab kub.
Cov Khoom Siv Hluav Taws Xob: Cov Pab Pawg Muag Khoom Yuav Tsum Tau Paub
Lub voj cua txias tsuas yog txhim khu kev qha raws li nws qhov kev sib txuas tsis muaj zog tshaj plaws. Micro-tawm hauv lub raj vuam tuaj yeem kaw lub server khib thiab puas tsuaj ntau txhiab nyiaj hauv GPU kho vajtse. Qhov no yog vim li cas cov ntsiab lus tshwj xeeb tseem ceeb dua li hauv lwm daim ntawv thov txias.
Stainless hlau 316L raws li cov khoom Standard
Hom 316L stainless hlau yog kev lag luam siv rau cov kav dej txias. Cov khoom siv molybdenum cov ntsiab lus (2-3%) muab pitting tsis kam nyob rau hauv ib puag ncig chloride, thiab cov pa roj carbon tsawg (max 0.03%) tiv thaiv rhiab heev thaum vuam.
Rau pab pawg muag khoom, cov ntsiab lus tshwj xeeb uas tseem ceeb yog:
- Internal nto roughness: Ra Tsawg dua lossis sib npaug ntawm 0.4 μm tiv thaiv cov khoom sib xyaw thiab biofilm tsim nyob rau hauv lub voj voog coolant
- Dimension kam rau ua: mating nto ntawm lub raj thiab cov khoom sib txuas yuav tsum tuav kom zoo ib yam rau batch
- Weld zoo: orbital vuam nrog tswj cov cua sov input minimizes weld hlaws protrusion rau hauv txoj kev khiav
- Ntawv pov thawj traceability: cov ntaub ntawv pov thawj zeb (MTC) thiab cov ntaub ntawv pov thawj xau yuav tsum nrog txhua pawg
Regional Demand Trends
North America coj AI kev siv nyiaj txiag hauv tsev, uas tau tsav los ntawm kev siv nyiaj ntau dua. Teb chaws Europe ua raws li cov cai nruj dua kev siv hluav taws xob (EU Energy Efficiency Directive) thawb ua kua dej txias. Asia-Pacific, tshwj xeeb tshaj yog Tuam Tshoj thiab Cov Neeg Esxias Qab Teb Hnub Tuaj, tab tom ntsuas AI cov ntaub ntawv chaw nyob ntawm qhov nrawm uas tam sim no sib tw North America.
Txhua cheeb tsam muaj cov qauv kev muab khoom sib txawv:
- North America: Nyiam cov neeg muag khoom nrog cov chaw khaws khoom hauv zos thiab cov ntaub ntawv ISO-cov ntawv pov thawj zoo. Cov ntaub ntawv ua raws cai (RoHS, REACH) yog qhov yuav tsum tau ua.
- Teb chaws Europe: Yuav tsum muaj tag nrho cov ntaub ntawv traceability thiab CE - cim cov khoom. Cov neeg ua haujlwm German thiab Nordic txheeb xyuas cov chaw muag khoom ntawm -qhov chaw ua ntej tsim nyog.
- Asia -Pacific: Nqe-rhiab heev tab sis zoo dua- tsom raws li AI server ceev nce. Kev xa khoom sai sai yog qhov sib txawv.
2025-2030 Outlook
Kev hloov pauv mus rau cov kua dej txias rau AI infrastructure tsis yog ib qho qauv - nws yog qhov kev hloov pauv ntawm cov ntaub ntawv chaw ua haujlwm li cas. Kev ua lag luam yuav sib sau ua ke nyob ib puag ncig cov neeg muag khoom uas ua kom pom qhov ua tau zoo dua ntawm qhov ntsuas. Cov txheej txheem txheej txheem yuav nce ntxiv, tab sis cov khoom zoo thiab kev tswj xyuas cov txheej txheem yuav nyob twj ywm qhov tseem ceeb sib txawv.
Cov neeg muab khoom siv nrog cov txheej txheem vuam uas tau lees paub (ISO 3834), kev tswj hwm kev huv huv hauv tsev, thiab cov ntaub ntawv khaws tseg tau muab tso rau txhawm rau ntes feem ntau ntawm qhov xav tau hyperscale. Qhov no yog kev ua lag luam kev muaj tiag hauv 2025 thiab txoj hauv kev rau xyoo tas los.
