Kev Xaiv Khoom Siv Rau Cov Kav Dej Txias Hauv Chaw Khaws Ntaub Ntawv —— Kev Tshawb Fawb Txog Cov Hlau, Elastomers, thiab Polymers Raws Li Qhov Xwm Txheej

Kev Taw Qhia: Qhov Kev Sib Tw Piping hauv AI Era

Kev txias ua kua sai sai no yog txoj hauv kev tseem ceeb los daws qhov teeb meem kev tswj hwm thermal thiab kev txuag hluav taws xob ntawm kev suav AI siab. Lub zog ib-rack tau nce ntxiv los ntawm 10-20 kW ib txwm mus rau ntau dua 50 kW, nrog rau qee qhov xwm txheej ultra-high-density tshaj 100 kW. Hauv cov txheej txheem txias kua txias, cov kav dej nqa lub luag haujlwm tseem ceeb ntawm kev thauj khoom thiab faib cov dej txias, thiab nws cov khoom xaiv cuam tshuam ncaj qha rau kev ntseeg siab ntawm lub kaw lus mus sij hawm ntev, lub sijhawm tsim kho, thiab cov nqi ua haujlwm.

Qhov nyuaj ntawm kev xaiv cov khoom siv tau loj hlob ntau vim tias cov tshuab ua kom txias kua hloov zuj zus los ntawm cov voj voog kaw yooj yim mus rau ntau theem architectures uas muaj ntau yam coolants, qhov kub thiab txias, thiab cov kev xav tau kev ua tau zoo. Cov lus qhia kev lag luam rau cov tshuab ua kom txias kua tam sim no lees paub ntau yam khoom siv siab heev ua cov khoom ntub dej tsim nyog, txhawb kev siv dav dav ntawm cov kev daws teeb meem ua tau zoo hauv cov ntawv thov txias ntawm lub chaw khaws ntaub ntawv tiam tom ntej.

Tsab xov xwm no tshuaj xyuas peb pawg khoom tseem ceeb - hlau, elastomers, thiab engineered polymers - tshuaj xyuas lawv lub zog, kev txwv, thiab cov xwm txheej siv zoo tshaj plaws raws li kev xyaum ua engineering tam sim no thiab cov qauv tshiab.

Hlau Tsis Muaj Hlau: Tus Neeg Ua Haujlwm Ib Txwm Muaj

Vim li cas Stainless tseem yog lub hauv paus

Cov kav dej hlau tsis xeb tau ntev los ua qhov kev xaiv tseem ceeb rau cov chaw khaws ntaub ntawv txias vim nws lub zog siab, tiv taus siab zoo, thiab lub hauv paus thev naus laus zis laus. Hauv CDU cov kav dej sab hauv, 316L yog siv ua cov khoom siv txheem rau feem ntau cov ntawv thov, muaj kev sib raug zoo nrog dej deionized thiab dej-glycol sib xyaw. Lub neej tsim ntawm cov khoom siv ntawm 70-100 xyoo nyob rau hauv cov xwm txheej ua haujlwm ib txwm ua rau nws nyiam rau cov chaw tsim khoom tseem ceeb.

Kev lag luam tau tsim cov qauv thiab kev coj ua dav dav nyob ib puag ncig cov kav dej hlau tsis xeb. ASME B31.3 muab cov qauv tsim, nrog cov txheej txheem vuam tsim nyog rau ASME IX lossis EN ISO 15614. Rau kev xa tawm hyperscale, kwv yees li 90% ntawm cov pob qij txha yog orbital-welded, muab cov welds rov ua dua, tag nrho-nkag mus, roj-purged.

304 vs. 316L: Kev Txiav Txim Siab Txog Khoom Siv

Qhov kev xaiv ntawm 304 thiab 316L yog qhov kev txiav txim siab tseem ceeb hauv kev tsim kho uas muaj feem cuam tshuam mus sij hawm ntev. Rau cov dej txias hauv dej (dej, cov kua glycol), 304 (06Cr19Ni10) feem ntau pom zoo ua qhov pib. Txawm li cas los xij, rau cov chaw muaj chloride lossis cov kua dej / roj av uas muaj fluorinated, 316L (022Cr17Ni12Mo2) lossis cov qib siab dua yog qhov yuav tsum tau ua.

Qhov sib txawv tseem ceeb vim tias txawm tias cov khoom me me tsis sib xws tuaj yeem ua rau kev ua haujlwm poob qis vim yog cov dej nag tsim, cov pa roj hloov pauv, lossis xeb ntawm qhov chaw. Hauv cov voj voog txias ncaj qha mus rau chip, qhov twg microchannels rhiab heev rau cov khoom me me, cov txiaj ntsig ntawm kev puas tsuaj ntawm cov khoom tuaj yeem hnyav heev.

Cov Nqi Zais Cia ntawm Cov Tshuab Hlau

Txawm hais tias nws muaj zog, cov kav dej hlau tsis xeb muaj cov kev txwv uas pom tseeb dua hauv kev siv cov khoom siv ntau:

Elastomers: EPDM thiab PTFE rau Kev Sib Txuas Yooj Yim

EPDM: Elastomer ua haujlwm

Rau cov dej thiab glycol txias-phaj kua txias systems, EPDM (ethylene propylene diene monomer) yog qhov kev xaiv tseem ceeb elastomer. Nws cov txiaj ntsig tseem ceeb suav nrog kev laus zoo heev thiab kev tiv thaiv corrosion, qhov kub ua haujlwm feem ntau ntawm -40 ° C txog + 120 ° C, thiab cov nqi tswj tau.

EPDM siv dav rau kev sib txuas yooj ywm, cov foob, thiab cov kav dej uas xav tau kev pab txav mus los. Kev sim cov khoom siv sib xws tau ua pov thawj tias EPDM ruaj khov nrog cov dej txias uas siv ntau, txo qhov kev pheej hmoo ntawm kev puas tsuaj thiab ua kom muaj kev ruaj khov ntawm cov tshuaj lom neeg rau lub sijhawm ua haujlwm ntev. EPDM uas kho nrog peroxide raug pom zoo tshwj xeeb rau cov tes hauj lwm kua dej hauv chaw khaws ntaub ntawv, muab kev ruaj khov zoo dua piv rau cov hloov pauv uas kho nrog sulfur.

PTFE: Kev daws teeb meem siab

Rau cov dej uas muaj fluorinated immersion, cov kev siv kub siab, thiab cov kev xav tau ntev hauv supercomputing thiab high-density AI compute, PTFE (polytetrafluoroethylene) yog qhov kev xaiv tus qauv hauv kev lag luam. Cov hoses txias corrugated PTFE hloov kho tuaj yeem ua haujlwm ruaj khov thoob plaws ntau qhov kub ntawm -60 ° C txog + 260 ° C, nrog rau kev laus qeeb qeeb thiab lub neej ua haujlwm ntev dua.

FEP (fluorinated ethylene propylene), ib qho fluoropolymer cuam tshuam, muaj cov txiaj ntsig ntxiv: kev ruaj khov tshuaj zoo heev, qhov kub siab melting nrog kev ua haujlwm kub ntawm -85 ° C txog 200 ° C, thiab cov khoom siv hluav taws xob zoo heev. Nws feem ntau siv rau cov kua txias txias RCM-rau-server kev sib txuas.

Qhov zoo tshaj plaws ntawm cov fluoropolymers yog lawv qhov kev ruaj khov tshuaj lom neeg zoo heev. Tsuas yog thaum muaj kev sib xyaw nrog cov khoom fluorine ntawm qhov kub siab, cov hlau alkali uas yaj, thiab chlorine trifluoride, lawv tseem tsis muaj xeb thaum sib cuag nrog lwm cov tshuaj lom neeg. Qhov no ua rau lawv zoo tagnrho rau cov dej txias uas muaj zog thiab xav tau lub neej ntev.

Cov Polymers Tsim Kho: Txoj Kev Thib Peb Tshiab

PVDF: Kev lees paub los ntawm OCP

Ib qho tseem ceeb hauv kev siv polymer tau tshwm sim thaum GF tau txais OCP Inspired ™ kev lees paub rau nws cov PVDF-based in-rack manifold rau kev txias kua ncaj qha-rau-chip - thawj polymer-based manifold kom tau txais qhov kev lees paub no hauv Open Compute Project program.

Lub PVDF manifold tau tsim los txhawb nqa cov chaw tswj hwm thermal uas xav tau qhov twg cov dej txias huv, kev tiv thaiv corrosion, thiab kev ntseeg tau mus sij hawm ntev yog qhov tseem ceeb. Tsis zoo li cov manifolds hlau ib txwm muaj, cov kev daws teeb meem siv cov qauv polymer tsim los txhawb kev faib cov dej ntws sib npaug thoob plaws txhua qhov chaw tawm, pab tswj kev ua haujlwm txias ruaj khov thiab rov ua dua thoob plaws hauv lub khib. Kev tsim kho PVDF sib dua kuj ua rau kev ua haujlwm tsis muaj corrosion thiab kev sib koom ua ke yooj yim los ntawm kev sib txuas yooj yim thiab kev xaiv mounting.

Txhua lub manifold yog tsim tshwj xeeb raws li cov neeg siv khoom lub txee thiab cov kev xav tau txias thiab dhau los ntawm 100% kev sim siab ua ntej xa khoom. Lub tswv yim manifold twb tau lees paub los ntawm ntau qhov pov thawj ntawm lub tswv yim thiab kev teeb tsa chaw khaws ntaub ntawv nyob thoob plaws Asmeskas, Tebchaws Europe, thiab Asia-Pacific.

Vim li cas Polymer Systems thiaj li tau txais kev rub tawm

Cov ntaub ntawv engineering rau polymer piping txuas ntxiv mus dhau qhov kev lees paub OCP:

Cov Ciam Teb ntawm Daim Ntawv Thov

Cov kav dej polymer tsis tau muab tso rau qhov chaw uas yuav hloov cov kav dej hlau tag nrho. Cov ciam teb ntawm kev siv tau yuav tsum txiav txim siab los ntawm cov xwm txheej ua haujlwm:

Lub Ntsiab Cai Sib Piv Cov Khoom Siv Uas Muaj Txheej

Kev coj ua hauv kev lag luam tam sim no ua raws li txoj kev sib phim cov khoom siv sib txawv, lees paub tias cov txheej txheem sib txawv ntawm cov kua txias muaj cov xwm txheej ua haujlwm sib txawv thiab cov kev cai ua haujlwm sib txawv:

Qhov sib txawv ntawm kev siv polymer yog txhawb nqa los ntawm OCP ecosystem txoj kev txhawb nqa rau kev sib koom ua ke thiab ntau tus neeg muag khoom cov kua txias los ntawm kev sib txuas lus txheem thiab cov txheej txheem khoom siv tau lees paub. Cov lus qhia kev lag luam lees paub ntau yam polymers siab heev ua cov ntaub ntawv ntub dej tsim nyog, txhawb kev siv dav dav ntawm cov thev naus laus zis polymer ua tau zoo hauv cov chaw khaws ntaub ntawv tiam tom ntej.

Xaus lus

Kev xaiv cov khoom siv rau cov kav dej txias tsis yog ib qho yooj yim xaiv ntawm cov hlau thiab lwm yam. Cov xim ntawm cov khoom siv uas nthuav dav - los ntawm cov hlau tsis xeb (304, 316L) mus rau elastomers (EPDM, PTFE, FEP) mus rau cov polymers tsim (PVDF, HDPE, PP-H) - muab cov engineers nrog cov kev xaiv kom phim cov kev xav tau kev ua haujlwm thiab cov xwm txheej ua haujlwm.

Qhov tseem ceeb yog kev nkag siab tias tsis muaj ib yam khoom siv twg zoo tshaj plaws rau txhua daim ntawv thov. Kev lees paub OCP-Inspired ntawm PVDF manifolds qhia txog kev pom zoo tseem ceeb ntawm kev lag luam ntawm cov kev daws teeb meem polymer, tab sis cov hlau tseem ceeb rau qhov chaw siab, kub siab, thiab tshuaj lom neeg. Yav tom ntej yuav nyob hauv cov txheej txheem sib xyaw uas sib xyaw cov zog ntawm txhua pawg khoom siv, siv raws li qhov xav tau tshwj xeeb ntawm txhua theem hauv cov qauv txias kua.
