"Zopha Zosaoneka" za Mapaipi Oziziritsira Madzi——Kupewa Kuopsa kwa Kupanikizika, Kudzimbiri, ndi Ukhondo

Chiyambi: Ziwopsezo Zobisika Mkati mwa Chizunguliro

Ngakhale kuziziritsa madzi kumabweretsa mphamvu yosayerekezeka yosamalira kutentha ku malo osungira deta a AI okhala ndi anthu ambiri, kumabweretsanso zoopsa zomwe makina oziziritsira mpweya wamba sanakumanepo nazo. Kuyenda kwa mpweya wozizira, dzimbiri, ndi kuipitsidwa zimaonedwa ngati "zakupha zosaoneka" zitatu za mapaipi oziziritsira madzi. Ngati sizikutsatiridwa, zotsatira zake zimayambira pa kulephera kwa kuziziritsa bwino mpaka kulephera kwathunthu kwa ma racks onse.

Malangizo ochokera ku ASHRAE akuwonetsa kuti ukhondo wa zoziziritsira ndi chinthu chofunikira kwambiri kuti madzi aziziritsa mwachindunji. Izi zikutanthauza kusamalira ndi kuyang'anira nthawi zonse kuti madzi aziziritsa komanso kuwononga ma seva ndi zomangamanga. Kukhala ndi malingaliro akuti "mudzaze ndi kuiwala" za kuziziritsa madzi kungayambitse mavuto akulu.

Kupanikizika Kwambiri: Kuyambira Kutopa Pang'onopang'ono Mpaka Kupasuka Mwadzidzidzi

Zotsatira za Kupanikizika ndi Kutentha

Kupanikizika kwambiri kwa dongosolo kumayambitsa kulephera kwakukulu. Malangizo aukadaulo a ASHRAE TC 9.9 akugogomezera kuti kupanikizika kwa zigawo zonse za Technology Cooling System (TCS) kuyenera kumvedwa ngati gawo la njira yopangira. Ngati kupanikizika kulikonse kwa gawo lililonse la dongosolo kupitirira kukakamizidwa kwa gawo limenelo, kungayambitse vuto la kulephera—makamaka makamaka zida za IT, komwe chiopsezo chake ndi kulephera kokwera mtengo.

Chitsanzo cha hydraulic chikulimbikitsidwa kuti chitsimikizire kuti kuthamanga kwa mpweya kukumveka bwino nthawi zonse mu dongosolo. Kusanthula kuthamanga kwa mpweya kuyenera kuphatikizapo zinthu zomwe sizikugwira ntchito bwino, kuphatikizapo kuthamanga kwa mpweya ndi kudzaza, kutalika kwa mpweya, kuthamanga kwakukulu komwe kumayikidwa ndi ma valve ochepetsa kuthamanga kwa mpweya mu dongosolo, kuthamanga kwa mpweya musanayambe kudzaza thanki yowonjezera, ndi kuthamanga kwa mpweya panthawi yolumikizira kapena kutseka zida.

Kulumikizana kwa kutentha ndi kupanikizika n'kofunika kwambiri. Mu zochitika za makompyuta okhala ndi kuchuluka kwakukulu, njira yabwino yolumikizirana ingapangidwe: kukwera kwa katundu → kukwera kwa kutentha → kukwera kwa kupanikizika → kupsinjika kwa dongosolo kumawonjezeka → kulephera kumawonjezeka.

Zofunikira pa Kuchepetsa Kupanikizika ndi Chitetezo

IEC 62368-1 (Kope Lachinayi) imafuna mayeso a chitetezo cha kuthamanga kwa madzi ndi 1.5x kuposa kuthamanga kwakukulu kogwira ntchito. Valavu yochepetsera kuthamanga kwa makina iyenera kuyikidwa pansi kuposa kuthamanga kwakukulu kovomerezeka, komwe opanga zida za IT ayenera kufotokoza mu template ya kutentha kwa malonda awo. Opanga ambiri a CDU amapereka mavavu ochepetsera kuthamanga, omwe ayenera kusankhidwa ndikugwirizana ndi zofunikira za makinawo.

Kawirikawiri, makina opangira mapaipi amkati mwa CDU nthawi zambiri amayesedwa kupanikizika pa kuthamanga kwa 1.5x. Mwachitsanzo, Vesfil imatsimikizira makulidwe a khoma ndipo imachita kusanthula kupsinjika motsatira ASME B31.3, kuteteza ntchito pansi pa kupsinjika kwakukulu mpaka 25 bar (360 psi).

Kudzikundikira: Kudzikundikira kosatha kwa machitidwe amagetsi

Kugwirizana kwa Zinthu Zachilengedwe monga Mzere Woyamba wa Chitetezo

Kudzikundikira ndiye chiwopsezo chachikulu cha mapaipi achitsulo. Mu CDU, kudontha kamodzi kokha kungayambitse kutseka kwakukulu. Kusankha zinthu ndikofunikira kwambiri: Chitsulo chosapanga dzimbiri cha 316L chimagwiritsidwa ntchito ngati chinthu chokhazikika pa ntchito zambiri zokhazikika, zomwe zimagwirizana bwino ndi madzi osasungunuka ndi zosakaniza zamadzi-glycol.

Pa malo okhala ndi chloride kapena mafuta opangidwa ndi fluorinated fluid/mineral, pamafunika ma grade 316L kapena apamwamba. Ngati mukugwiritsa ntchito madzi a m'nyanja kapena ma chloride ena amphamvu, SMO254 imayima pomwe chitsulo chosapanga dzimbiri chimayamba kusweka; titaniyamu ndi chisankho chabwino kwambiri pamavuto oopsa.

Ndondomeko ya muyezo wa T/CAEE (征求意见稿) imati pa zinthu zoziziritsa madzi (madzi, glycol solutions), 06Cr19Ni10 (304) ndi yovomerezeka, pomwe malo okhala ndi chloride kapena fluorinated fluid/mineral oil media amafunika 022Cr17Ni12Mo2 (316L) kapena ma grade apamwamba..

Kusakhazikika: Kukonzekera Kofunika Kwambiri Pamwamba

Kuchepetsa mpweya moyenera ndikofunikira kuti madzi asawonongeke. Malangizo a ASHRAE TC 9.9 akugogomezera kuti gawo la makina opachikira madzi lomwe silinachotsedwe mpweya likhoza kuwononga ntchito yonse ya makinawo. Kuchepetsa mpweya kumatha kuchitika m'malo osungiramo madzi (kuyeretsa kolamulidwa, kuchepetsa mpweya pogwiritsa ntchito mankhwala a nitric kapena citric, kutsuka bwino, kuumitsa, ndi kulongedza) kapena m'munda (kuyeretsa kolamulidwa, kuchepetsa mpweya pogwiritsa ntchito mankhwala, kuletsa mpweya, kutsuka bwino).

Kutsimikizira kuti chitsulo cha passivation chikuyenera kutsimikizira kuchotsa chitsulo chomasuka ndi momwe chilili pamalopo pogwiritsa ntchito njira zovomerezeka monga malangizo a ASTM A380/A967. Pa mapaipi achitsulo chosapanga dzimbiri, malo amkati opukutidwa ndi magetsi kufika pa Ra ≤0.6 μm (kapena mpaka 0.2 μm) amapereka kutseka bwino komanso kukana kwambiri kuukira kwa mankhwala.

Kugwirizana kwa Zinthu Zosindikiza

Zisindikizo ndi ma gasket nthawi zambiri zimanyalanyazidwa ndi zoopsa za dzimbiri. Muyezo woyeserera umafuna kuti zipangizo zosindikizira (ma O-rings, ma gaskets) zigwirizane ndi chogwirira ntchito. Pambuyo poviika mu choziziritsira chomwe chatchulidwa (kutentha × nthawi), kusintha kwa voliyumu kuyenera kukhala pakati pa -5% ndi +10%, ndipo kusintha kwa kuuma sikupitirira ±5 Shore A.

Ukhondo: Vuto la Moyo Wonse Kuyambira Kukhazikitsa Mpaka Kugwira Ntchito

Chiwopsezo cha Tinthu Tating'onoting'ono

Makina oziziritsira madzi amakhala ndi kulekerera kochepa kwambiri kuipitsidwa kuposa makina oziziritsira mpweya. Ma microchannels a plate ozizira ndi ang'onoang'ono kwambiri komanso osavuta kuwazindikira; tinthu tating'onoting'ono tomwe timakhala ndi tinthu tating'onoting'ono tingatseke njirazi ndikusokoneza magwiridwe antchito ozizira, kapena choipa kwambiri, kuwononga ma chips kapena kuyambitsa nthawi yogwira ntchito.

Kafukufuku wokhudza kuipitsidwa kwa kutentha kwa makina osinthira kutentha wasonyeza kuti kutentha kumachepa ndi 14% ndipo kutsika kwa mphamvu kumawonjezeka ndi 45% pamene zinthu zodetsa zikuchulukana. Popeza ma seva amakono a AI amadalira kuyenda kwabwino kwa choziziritsira komanso kuchotsa kutentha, ngakhale mavuto ang'onoang'ono okhudza ubwino wa madzi amatha kuwonjezera chiopsezo cha kutentha, kuwonongeka kwa zida, komanso nthawi yopuma yosakonzekera.

Miyezo ndi Mayeso a Ukhondo

Muyeso wa T/CAEE woyambirira umalongosola zofunikira pamlingo wa ukhondo malinga ndi ISO 4406 pa kuipitsidwa kwa tinthu tolimba m'madzi. Vesfil imagwiritsa ntchito mayeso a DI water flush ndi kuchuluka kwa tinthu asanaperekedwe. Gulu lililonse limayesedwa ndi helium mass spectrometry (≤1×10⁻⁶ mbar·L/s) ndi mayeso a hydrostatic pa 1.5x operating pressure.

Pa mapaipi osapanga dzimbiri, kuwotcherera kwa orbital kokha kumapanga ma weld ofanana, olowa mokwanira, otsukidwa ndi gasi omwe amachepetsa kuipitsidwa. Pa makina a polima, kuwotcherera kwa infrared (IR) ndi njira yosakhudzana yomwe imapanga ma molecular bond ofanana popanda zinthu zodzaza kapena mpweya wowotcherera, kuchotsa zoopsa za kuipitsidwa.

Kuwunika ndi Kusefa Zoziziritsa

Mabizinesi abwino kwambiri amalimbikitsa kuyesa zoziziritsa pazigawo zitatu: poyambitsa kukhazikitsa maziko, chaka chilichonse panthawi yogwira ntchito, komanso kawiri pachaka pamakina omwe amathandizira ntchito za AI GPU zolemera kwambiri. Kuyesa zoziziritsa nthawi ndi nthawi kuli ngati kufufuza magazi kwa anthu nthawi zonse—kumathandiza kuzindikira mavuto omwe akubuka asanayambe kugwira ntchito kapena kudalirika.

Mafyuluta ndi ofunikira kwambiri kuti zinthu zikhale zaukhondo. Mu kuziziritsa madzi kotsekedwa, mafyuluta amapezeka m'malo osiyanasiyana, kuphatikizapo ma CDU ndi ma Rear Door Heat Exchangers (RDHx). Mafyuluta a "masokisi" otayidwa nthawi zambiri amagwiritsidwa ntchito poika ndi kutsuka, pomwe mafyuluta achitsulo ogwiritsidwanso ntchito amagwiritsidwa ntchito nthawi zonse ndipo amatha kutsukidwa.

Mapeto: Njira Yoyang'anira Zoopsa Zonse

"Zinthu zitatu zosaoneka zakupha" — kupanikizika, dzimbiri, ndi ukhondo — zimalumikizana. Zinthu zopanga dzimbiri zimatha kuwonjezera kuipitsidwa kwa tinthu tating'onoting'ono; kuthamanga kwa kupanikizika kumatha kufulumizitsa kutopa ndi kulephera pamalo omwe dzimbiri lafooka; kuipitsidwa kumatha kufulumizitsa dzimbiri popanga maselo a galvanic omwe ali m'deralo.

Njira yogwirira ntchito yonse imafuna:
