Intshayelelo: Izisongelo Ezifihlakeleyo Ngaphakathi Kwisijikelezo
Nangona ukupholisa ulwelo kuzisa amandla olawulo lobushushu angazange abonwe ngaphambili kumaziko edatha e-AI axineneyo, kukwazisa neseti yeengozi ezingazange zijongane neenkqubo zokupholisa umoya zemveli. Uxinzelelo, ukugqwala, kunye nongcoliseko zithathwa njengezona "zibulali ezingabonakaliyo" ezintathu zemibhobho yokupholisa ulwelo. Ukuba ayijongwanga, iziphumo ziqala ekusebenzeni kakubi kokupholisa ukuya ekungasebenzi kakuhle kweerakhi ezipheleleyo.
Isikhokelo soshishino esivela kwi-ASHRAE sichaza ucoceko lwe-coolant njengemfuneko ephambili yokusebenza ngokuthembekileyo kokupholisa ulwelo oluvela ngqo kwi-chip. Oku kuthetha ukwenza ulondolozo rhoqo kunye nokubeka iliso ukuthintela ukonakala kolwelo kunye nomonakalo kwiiseva kunye neziseko zophuhliso. Ukuba nengqondo "yokuzalisa uze ulibale" malunga nokupholisa ulwelo kunokubangela iingxaki ezinkulu.
Uxinzelelo Olugqithisileyo: Ukusuka Ekudinweni Kancinci ukuya Ekuqhekekeni Ngequbuliso
Isiphumo Sokudibanisa Uxinzelelo-Ubushushu
Uxinzelelo olugqithisileyo lwenkqubo lubangela uthotho lweempazamo. Isikhokelo sobugcisa se-ASHRAE TC 9.9 sigxininisa ukuba uhlalutyo loxinzelelo lwazo zonke izinto zeNkqubo yoKuphola kweTekhnoloji (i-TCS) kufuneka luqondwe njengenxalenye yenkqubo yoyilo. Ukuba uxinzelelo olukwinxalenye nayiphi na yenkqubo ludlula uphononongo lwaloo nxalenye, lunokubangela imeko yokungaphumeleli—ingakumbi kwizixhobo ze-IT, apho umngcipheko ungokusilela okubizayo.
Kucetyiswa imodeli ye-hydraulic ukuqinisekisa ukuba i-cascade yoxinzelelo iyaqondakala kuzo zonke iindawo kwinkqubo. Uhlalutyo loxinzelelo kufuneka luquke iimeko ezingaphandle kokusebenza okuqhelekileyo, okuzinzileyo, kubandakanya uxinzelelo lokufutha nokugcwalisa, ukuphakama okungaguqukiyo kwenkqubo, uxinzelelo oluphezulu olubekwe ziivalvu zokunciphisa uxinzelelo lwenkqubo, uxinzelelo lwangaphambi kokutshaja itanki yokwandisa, kunye nokuhamba koxinzelelo ngexesha loqhagamshelo okanye ukuqhawulwa kwezixhobo.
Ukudibanisa ubushushu noxinzelelo kubaluleke ngokulinganayo. Kwiimeko zokubala ezinoxinano oluphezulu, i-positive feedback loop inokwenziwa: ukunyuka komthwalo → ukunyuka kobushushu → ukunyuka koxinzelelo → ukunyuka koxinzelelo lwenkqubo → ukunyuka komngcipheko wokungaphumeleli.
Iimfuneko zokunciphisa uxinzelelo kunye nokhuseleko
I-IEC 62368-1 (uHlelo lwesi-4) ifuna uvavanyo lokhuseleko loxinzelelo lwe-hydrostatic oluphindwe kayi-1.5 kunoxinzelelo oluphezulu lokusebenza olulinganisiweyo. Ivalvu yokunciphisa uxinzelelo lwenkqubo kufuneka ibekwe ngaphantsi kunoxinzelelo oluphezulu olulinganisiweyo, ekufuneka abavelisi bezixhobo ze-IT bayichaze kwitemplate yobushushu yemveliso yabo. Abavelisi abaninzi be-CDU banikezela ngokwezifiso iivalvu zokunciphisa uxinzelelo, ekufuneka zikhethwe kwaye zihambelane neemfuno zenkqubo.
Enyanisweni, iinkqubo zemibhobho yangaphakathi ye-CDU zihlala zivavanywa uxinzelelo kuxinzelelo olusebenzayo lwe-1.5x. Umzekelo, iVesfil iqinisekisa ubukhulu bodonga kwaye yenza uhlalutyo loxinzelelo ngokwe-ASME B31.3, ikhusela ukusebenza phantsi koxinzelelo oluphezulu olufikelela kwi-25 bar (360 psi).

Ukubola: Ukubola Okungapheliyo Kweempendulo Ze-Electrochemical
Ukuhambelana kwezinto ezibonakalayo njengoMgca wokuQala woKhuselo
Ukugqwala sesona sisongelo siqhubekayo kwiipayipi zesinyithi. Kwi-CDU, ukuthontsiza kube kanye kunokubangela ukuvalwa okukhulu. Ukukhethwa kwezinto kubalulekile: Intsimbi engagqwaliyo engama-316L isetyenziswa njengesixhobo esiqhelekileyo kwiintlobo ezininzi zezicelo eziqhelekileyo, ehambelana kakuhle namanzi acocekileyo kunye nemixube yamanzi-glycol.
Kwiindawo eziqulethe i-chloride okanye i-fluorinated fluid/mineral oil media, kufuneka i-316L okanye ii-grades eziphezulu. Ukuba usebenza ngamanzi olwandle okanye ezinye ii-chloride ezirhabaxa, i-SMO254 ima apho intsimbi engagqwaliyo eqhelekileyo inokuqala ukuqhekeka; i-titanium ilukhetho olufanelekileyo kwiimeko ezirhabaxa kakhulu.
Uyilo lomgangatho we-T/CAEE (征求意见稿) icacisa ukuba kwii-coolants zamanzi (amanzi, izisombululo ze-glycol), i-06Cr19Ni10 (304) iyacetyiswa, ngelixa iindawo eziqulethe i-chloride okanye i-fluorinated fluid/mineral oil media zifuna i-022Cr17Ni12Mo2 (316L) okanye amanqanaba aphezulu..
Ukunyamezela: Ukulungiswa Komphezulu Obalulekileyo
Ukuhambisa umoya ngokufanelekileyo kubalulekile ekumelaneni nokugqwala. Isikhokelo se-ASHRAE TC 9.9 sigxininisa ukuba icandelo lenkqubo yemibhobho ENGAPHUMELELIYO linokulimaza ukusebenza kwenkqubo yonke. Ukuhambisa umoya kungenziwa kwiimeko zasefektri/evenkileni (ukucoca okulawulwayo, ukuhambisa umoya ngeekhemikhali nge-nitric okanye i-citric formulations, ukuhlamba ngokucokisekileyo, ukomisa, kunye nokupakishwa) okanye ebaleni (ukucoca okulawulwayo, ukuhambisa umoya ngeekhemikhali, ukuthomalalisa, ukuhlamba ngokucokisekileyo).
Ukuqinisekiswa kokudlula kufuneka kuqinisekise ukususwa kwesinyithi esikhululekileyo kunye nemeko yomphezulu eyamkelekileyo kusetyenziswa iindlela ezamkelekileyo ezifana nesikhokelo se-ASTM A380/A967. Kwimibhobho yentsimbi engagqwaliyo, iindawo zangaphakathi ezipholishwe ngombane ukuya kwi-Ra ≤0.6 μm (okanye ukuya kuthi ga kwi-0.2 μm) zibonelela ngokutywinwa okungcono kunye nokumelana okunamandla kuhlaselo lweekhemikhali.
Ukuhambelana kwezinto zokutywina
Iiseal kunye neegaskets zihlala zingajongwanga iingozi zokugqwala. Umgangatho wedrafti ufuna ukuba izixhobo zokutywina (ii-O-rings, iigaskets) zihambelane nendawo yokusebenza. Emva kokuntywiliselwa kwindawo epholisayo echaziweyo (ubushushu × ixesha), utshintsho lomthamo kufuneka lube phakathi kwe--5% kunye ne-+10%, kwaye utshintsho lobunzima lungadluli kwi-±5 Shore A.

Ucoceko: Umngeni wobomi bonke ukusuka ekufakweni ukuya ekusebenzeni
Usongelo lweeNgxenye
Iinkqubo zokupholisa ulwelo azinawo amandla okunyamezela ungcoliseko kuneenkqubo zokupholisa umoya. Iitshaneli ezincinci zepleyiti ebandayo zincinci kakhulu kwaye zinobuthathaka; amasuntswana amancinci anokuvala la matshaneli aze aphazamise ukusebenza kokupholisa, okanye okubi ngakumbi, onakalise iitships okanye abangele ixesha lokungasebenzi.
Uphando malunga nokungcoliswa kwe-heat exchanger lubonise ukwehla kokudluliselwa kobushushu ukuya kuthi ga kwi-14% kunye nokunyuka koxinzelelo ukuya kuthi ga kwi-45% njengoko ukungcola kuqokelelwa. Ngenxa yokuba iiseva ze-AI zanamhlanje zixhomekeke ekuhambeni okuchanekileyo kwe-coolant kunye nokususwa kobushushu, kwaneengxaki ezincinci zomgangatho wolwelo zinokunyusa umngcipheko wokuxinana kobushushu, ukonakala kwezixhobo, kunye nexesha lokungasebenzi elingalindelekanga.
Imigangatho yoCoceko kunye noVavanyo
Idrafti yomgangatho we-T/CAEE ichaza iimfuno zenqanaba lokucoceka ngokwe-ISO 4406 zongcoliseko lwe-particle eqinileyo kulwelo. I-Vesfil isebenzisa uvavanyo lwe-DI water flush kunye ne-particle count ngaphambi kokuba ifike. Indibano nganye ivavanywa nge-helium mass spectrometry (≤1×10⁻⁶ mbar·L/s) kunye novavanyo lwe-hydrostatic kwi-1.5x yoxinzelelo lokusebenza.
Kwimibhobho yentsimbi engagqwaliyo, ukuwelda okuzenzakalelayo kwe-orbital kuvelisa ukuwelda okufanayo, okungenayo ngokupheleleyo, okucociwe ngegesi okunciphisa ukungcoliswa. Kwiinkqubo zepolymer, ukuwelda kwe-infrared (IR) yinkqubo engaqhagamshelwanga edala iibhondi zemolekyuli ezifanayo ngaphandle kwezinto zokuzalisa okanye iigesi zokuwelda, okususa iingozi zokungcoliswa.
Ukubeka iliso kwi-coolant kunye ne-Filtration
Eyona ndlela ilungileyo yokusebenza kweshishini icebisa uvavanyo lwe-coolant ngamaxesha amathathu aphantsi: xa kumiselwa ukusekwa kwesiseko, minyaka le ngexesha lokusebenza okuqhelekileyo, kwaye kabini ngonyaka kwiinkqubo ezixhasa umthwalo womsebenzi we-AI GPU oxineneyo. Uvavanyo lwe-coolant oluqhubekayo lufana kakhulu nomsebenzi wegazi oqhelekileyo ebantwini—lunceda ekuchongeni imiba ekhulayo ngaphambi kokuba ichaphazele ukusebenza okanye ukuthembeka.
Izihluzi zibalulekile ekugcineni ucoceko. Kwindawo yokupholisa ulwelo evaliweyo, izihluzi zifumaneka kwiindawo ezininzi, kuquka iiCDU kunye neeRear Door Heat Exchangers (RDHx). “Izihluzi zesokisi” ezilahlwayo zihlala zisetyenziswa ngexesha lokufakelwa kunye nokucoca/ukuhlamba, ngelixa izihluzi zesinyithi eziphinda zisetyenziswe zisetyenziswa ngexesha lokusebenza okuqhelekileyo kwaye zinokucocwa.

Isiphelo: Indlela yoLawulo lweeNgozi eziBanzi
"Izibulali ezingabonakaliyo ezintathu"—uxinzelelo, ukugqwala, kunye nococeko—zidibene. Iimveliso zokugqwala zinokunyusa ukungcoliswa kweenxalenye ezincinci; ukuhamba koxinzelelo kunokukhawulezisa ukudinwa kunye nokungaphumeleli kwiindawo ezibuthathaka; ukungcoliswa kunokukhawulezisa ukugqwala ngokwenza iiseli ze-galvanic zasekuhlaleni.
Indlela ebanzi ifuna:
Njengoko omnye umthombo weshishini ephawula, inkqubo yokulawula ulwelo olupholisa ulwelo echazwe kakuhle ithintela ezi meko. Utyalo-mali kulawulo olusebenzayo luncinci xa luthelekiswa neendleko ezinokubakho zokungasebenzi kwiindawo ezinoxinano olukhulu lwe-AI.
