Data Center Liquid Cooling: Phau Ntawv Qhia Txog Kev Ua Haujlwm rau Siab -Density Computing
Raws li AI xam, siab - cov servers ua haujlwm tau zoo, thiab cov chaw khaws ntaub ntawv hyperscale txuas ntxiv nthuav dav, cov cua txias ib txwm tau mus txog nws qhov kev txwv lub cev thiab kev lag luam.
Cov kua ua kua txias tsis yog qhov kev sib tw yav tom ntej - nws tau dhau los ua qhov kev daws teeb meem tsim nyog rau kev txhim kho thermal efficiency, txo kev siv hluav taws xob, thiab txhawb nqa cov khib nyiab siab.
Hauv phau ntawv qhia no, koj yuav kawm:
Cov cuab yeej tseem ceeb ua kua txias siv hauv cov chaw khaws ntaub ntawv niaj hnub
Qhov sib txawv ntawm ncaj qha - mus rau -chip thiab immersion txias
Vim li cas cov kua fluorinated tau dav siv
Yuav ua li cas xaiv cov kua txias txias rau koj lub cev
Nrhiav cov kua dej txias? Saib cov khoom pom zoo hauv qab no.
Cov kua txias siv cov kua tshwj xeeb kom tshem tawm cov cua sov kom zoo dua li cua.
Piv nrog cua txias, kua-raws li cov tshuab muaj:
Kev hloov hluav taws xob ntau dua
Tsawg zog noj (txo PUE)
Support for high-density racks (>30 kWm)
Ua haujlwm ruaj khov dua kub
Qhov no ua rau cov kua txias tshwj xeeb yog tsim rau:
AI thiab GPU pawg
Edge data centers
High -ntaus enterprise servers

Liquid Cooling vs Cua Txias
| Qhov xwm txheej | Cua txias | Ua kua txias |
|---|---|---|
| Kub Hloov | Tsawg | Siab |
| Zog Efficiency | Nruab nrab | Siab |
| Rack Ceev | txwv | Siab heev |
| Suab nrov | Siab | Tsawg |
| Ntev - Tus Nqi Sij Hawm | Kev nce ntxiv | Ua kom zoo |
👉 Rau siab - suav suav, kua txias yog qhov kev xaiv.
Vim li cas Fluorinated Fluids siv nyob rau hauv cov kua txias
Fluorinated kua yog siv dav hauv immersion thiab precision txias tshuab vim lawv cov khoom tshwj xeeb:
Hluav taws xob tsis yog -conductive
Chemically ruaj khov
Tsawg nto nro
Kev ua haujlwm thermal zoo heev
Cov yam ntxwv no xyuas kom meej tias:
Kev nyab xeeb ua haujlwm ntawm cov khoom siv hluav taws xob
Lub neej ua haujlwm ntev
Txo kev pheej hmoo ntawm corrosion los yog residue
PFPE vs HFE: Yam dej txias twg koj yuav tsum xaiv?
PFPE (Perfluoropoyether)
Qhov zoo tshaj plaws rau:
Immersion txias tshuab
High -kub stability ib puag ncig
Qhov zoo:
ruaj khov heev
Tsis yog -flammable
Lub neej ntev
HFE (Hydrofluoroether)
Qhov zoo tshaj plaws rau:
Precision tu + txias
Kev siv hluav taws xob thiab semiconductor
Qhov zoo:
Ceev ceev evaporation
Cov khoom zoo sib xws
Tsawg viscosity
Kev sib piv ceev
| Khoom | PFPE | HFE |
|---|---|---|
| Kev ruaj ntseg | Siab heev | Siab |
| Volatility | Tsawg | Nruab nrab |
| Daim ntawv thov | immersion txias | Ntxuav & txias |
| Nqi | Siab dua | Nruab nrab |
👉 Xaiv cov kua dej zoo yog nyob ntawm koj qhov kev tsim qauv, qhov kub thiab txias, thiab kev txiav txim siab nqi.
Yuav ua li cas xaiv cov kua txias txias
Thaum xaiv cov kua dej txias, xav txog:
1. Cov kev xav tau cua sov
Thaum tshav kub kub load (kW ib rack)
Kev khiav hauj lwm qhov kub thiab txias
2. Qhov System Hom
Direct txias vs immersion
Qhib vs kaw - voj system
3. Kev sib haum xeeb
Khoom siv (plastics, seals, hlau)
Electronics kev nyab xeeb
4. Tag nrho cov nqi ntawm cov tswv cuab
