AI Cov Chaw Cov Ntaub Ntawv Hloov Mus Rau Siab -Tsuas Ua Kua Dej Txias: Vim Li Cas Stainless Hlau Yeeb Nkab Tseem Ceeb hauv 2026

Xyoo 2026, AI cov chaw zov me nyuam hauv Teb Chaws Asmeskas, Lub Tebchaws Yelemees, Nyiv, Kaus Lim Qab Teb thiab Sab Hnub Tuaj Asia tsis muaj kev sib cav ntxiv seb puas yuav siv cov kua ua kom txias dua -lawv tau ua qauv rau nws. Nrog NVIDIA B200/H200 thiab Vera Rubin platforms thawb ib qho -GPU fais fab dhau los 700W thiab khib ceev rau 30-50kW (qee rau 200kW), cua txias yog lub cev tsis siv. Lub hauv paus tshiab yog 45℃mov / 54℃rov qab dej loops khiav ntawm glycol - dej los yog dielectric kua, thiab cov yeeb nkab txuas CDU, manifold thiab txias phaj tau dhau los ua ib qho kev cia siab ntawm lub fwj, tsis yog khoom muag.
Tooj liab oxidizes thiab tso cov khoom hauv dej deionized. EPDM hose hardens, swells thiab xau tom qab 3-5 xyoos. Yas softens saum 50 degree. Tias yog vim li cas hyperscalers xws li Google (Project Deschutes CDU) thiab NVIDIA Rubin architecture tam sim no qhia 316L stainless hlau raws li cov khoom yuav tsum tau rau manifolds, cov kab nruj thiab hose cores. Kev tshawb fawb xyoo 2023 thoob plaws 45 lub chaw cov ntaub ntawv pom 78% ntawm qhov tsis tau npaj ua kom txias txias tau taug qab rov qab mus rau lub raj degradation, tsis yog twj lossis tswj.

Vim li cas 316L yeej nyob rau hauv siab -temp AI loops

316L (nrog 2–3% Mo, ultra- cov pa roj carbon tsawg) muab 3-5 × pitting corrosion kuj ntawm 304 hauv chloride-cov kabmob coolant, muaj sia nyob 10-xyoo kev laus kuaj nrog pitting tus nqi<0.1 mm/year, and keeps inner-wall roughness below 0.8 µm after electrolytic polishing-so no metal ions shed into micro-channels. One Frankfurt operator in March 2024 lost 14 hours of AI compute because a copper-nickel weld joint on a CDU branch leaked; the replacement run was rebuilt with 316L EP pipe and helium leak test <1×10⁻⁹ Pa·m³/s.

304 tseem muaj qhov chaw: nyob rau hauv cov dej ntshiab DI los yog kaw glycol loops nrog tswj pH, Tuam Tshoj Super Tech 304 yeeb nkab muab tus nqi zoo tshaj plaws -kev ua tau zoo thiab muaj nyob rau hauv ntim. Tab sis rau ntug dej hiav txwv Nyij Pooj / Kaus Lim Qab Teb, Cov Neeg Esxias Qab Teb Hnub Tuaj siab -RH Halls, lossis ib qho immersion -CDU uas nyob ib sab, 316L yog qhov kev yuav khoom.
