Iiyunithi Zokuhambisa I-Coolant (CDUs): Isizathu Sokuba Uyilo Lwemibhobho Lubaluleke Kakhulu Kwi-liquid Cooling Yeziko Leddatha

Uchaza inkqubo yokupholisa isizinda sedatha, kwaye iyunithi yokusasaza isipholisi (CDU) isoloko itsala umdla. Kodwa nantsi inyaniso engakhululekanga abachazi abaninzi bayifunda kade kakhulu: I-CDU ithembekile kuphela njengokuba zithembekile iipayipi ozibholithayo kuyo. Kwesi sikhokelo sichaza lonke unxulumano lwempahla — ukusukela ekunyukeni kwe-AI ukuya kwityhubhu yentsimbi engatyiwayo ekwiraq yakho — kwaye sikubonisa kanye ukuba kutheni uyilo lweepayipi lugqiba ukuba ingaba ufakelo lwakho lwenkqubo yokupholisa ngolwelo luya kuthunyelwa ngexesha okanye luyakuphunga ngosuku lokuqala.

Uthotho lweemfuno zemarike olusemva kweepayipi ze-CDU

Phambi kokuba ukhethe ubungakanani betyhubhu, kufuneka uqonde. kutheni Imarike itsala kule nxalenye ngamandla kakhulu. Uchungechunge lujongeka ngolu hlobo:

1. I-AI kunye nemithwalo yomsebenzi ekwinqanaba eliphezulu kakhulu zityhalela ubuninzi bamandla kwiiraki ngaphaya kwe-50–100 kW, apho ukupholisa ngomoya kungakwaziyo ukulandela.
2. Oko kunyanzela abaqhubi ukuba bajikele kwii-liquid cooling systems ezakhelwe kwi-direct-to-chip kunye nee-rear-door loops.
3. Umlingo ngamnye olulwelo udinga Iyunithi yokusasaza isipholisi (CDU) Ukucinezela, ukuhluza, nokudibanisa ngobushushu amanzi eziko kunesipholisi.
4. Kwaye i-CDU nganye idinga Imibhobho engavuzi kwaye engatyiwa — iiphaneli zokupompa, iimanifoldi, kunye nemijikelo yokupholisa — ukuhambisa ulwelo ngokukhuselekileyo.

Kuwe njengomthengi we-B2B, umyalezo ocacileyo ngulo: Umthamo we-CDU ngowona mqondiso uphambili wemfuno yemibhobho yokupholisa yentsimbi engatyiwayo. Xa ii-hyperscalers zibhengeza iikampasi ezintsha, uluhlu lwakho lwee-RFQ zemibhobho lulandela kwikota ezizayo.

Into Eyenzwa yi-CDU Ngokwenene (ngemizuzwana engama-30)

I-CDU yintliziyo ye-hydraulic yenkqubo yokupholisa ulwelo. Ithatha amanzi ashushu eziko kwelinye icala, iwatyhutyha kwisiguquli sobushushu sepleyiti, ize ityhalele ulwelo olupholisayo olulawulwa ubushushu kuyo. Ipayipi yentsimbi engatyiwayo i-304L xa ithelekiswa ne-316L Inethiwekhi kwelinye icala. Ilawula intloko yepompo, ukuhluza, ukulungelelanisa ukuhamba, nokufumana ukuvuza. Ukuba wenze impazamo kuyo nayiphi na kwezi zinto, imibhobho — hayi iseva — iyasilela kuqala.

Isizathu Sokuba Uyilo Lweepayipi Libe Ngumqhina Obalulekileyo

Ungathenga eyona CDU igqwesileyo kwimarike kodwa usalahlekelwa kukusebenza kwayo ngenxa yemibhobho embi. Kulapho uyilo lwenzi lapha umahluko:

1. Ukuhla koxinzelelo kumisela uhlahlo-lwabiwo-mali lwakho lwempompo

Iipayipi ezinkulu kakhulu okanye ezihanjiswe kakubi zibangela ukuhla koxinzelelo, nto leyo enyanzela iimpompo ezinkulu, amandla amaninzi, kunye neekhabhathi ezinengxolo engaphezulu. Ubungakanani obufanelekileyo ipayipi yentsimbi engatyiwayo ye-duplex Igcina isantya kwindawo efanelekileyo eyi-1.5–3 m/s.

2. Ingozi Yokuvuza Yingxaki Yenkqubo

Ukuphuma kwe-oyile kwindawo enye yokudibanisa i-manifold kunokukhupha umqolo weeraki ekusebenzeni. Imibhobho yentsimbi engatyiwayo egudileyo ngaphakathi, ethatyathelwe ngokujikelezayo kwaye inenkqubo eqinisekisiweyo yokuyikhusela, isoloko igqwesa iindawo zokudibanisa ezinemisonto.

3. Ikhemistri yeCoolant ifuna i-Alloy efanelekileyo

Amanzi angena-ion kunye nemixube ye-glycol ziyabola iintsimbi ezingafanelekanga. I-304L ne-316L ezingagqwali, kunye needigri ze-duplex zoxinzelelo oluphezulu, zikunika umda wokuhambelana owufunayo.

4. I-Manifold kunye ne-Loop Topology zilawula ukukwazi kwakho ukwanda

Eyilwe kakuhle Umphakathi wokupholisa Ikunika ithuba lokongeza iiraki ngaphandle kokufaka izibhobho ezintsha kwiloop yonke. I-topology embi yenza ukuba yonke intlalo-nkqubo ibe kukuvala.

Ukukhethwa Kwezinto: Isizathu Sokuba Imibhobho Yentsimbi Engatyiwayo Ibengcono Kwi-CDU

Xa uchaza umjikelo wokupholisa, isinyithi esingatyiwayo sisetyenziswa ngesiqhelo ngesizathu:

Udinga uncedo ekukhetheni i-grade? Isikhokelo sethu sepayipi yentsimbi engatyiwayo i-304L vs 316L sichaza umahluko ngokwe-chemistry ye-coolant kunye nedidi loxinzelelo.

Uthungelwano lweMfuno loMthengi we-B2B: Indawo oKuyo

Ukuqonda ikhonkco kukuxelela ongubani ukuthengisela yintoni kwisitokhwe. Ukuhamba kukuthi:

1. Abakhi abangaphezu komlinganiselo kunye nabaqhubi bokwabelana ngeziko ledatha Imizila yophuhliso enomthamo omiselweyo.
2. Ii-OEMs nee-ODMs ze-CDU Yila iiyunithi kwaye ukhuphe iinkcukacha zemibhobho.
3. Abadibanisi beenkqubo zolwelo Yakha iimanifold kunye neelophu zokupholisa.
4. Abaxhasi beepayipi nezixhobo zazo — njengeKaixin — zizalisekisa uLuhlu lwezixhobo.

Ukuba ungumthengisi, umdibanisi, okanye i-OEM, umyalezo ucacile: Fumana isiqinisekiso somthombo wakho wentsimbi engatyiwayo ngoku. Amaxesha okulinda kwiipayipi ezingqinisisiweyo ezidityaniswe nge-orbital-welding ngumqobo omtsha. Hlola iyethu Izisombululo zeetiyubhu ziziko ledatha ukubona ukuba zinjani iilenga needigri ezilungele i-BOM.

Uluhlu lokujonga lweemfuno zokufakwa kweepayipi ze-CDU

Sebenzisa olu luhlu lokujonga olukhawulezayo phambi kokuba ukhuphe umzobo wemibhobho ye-CDU. (Inguqulelo enokuprintwa iyafumaneka xa iceliwe.)

Imibuzo Ebuzwa Rhoqo

Umjikelo wemibhobho we-CDU kufuneka uyilelwe yeyiphi ireyithi yokuhamba kunye noxinzelelo?

Iilooops ze-CDU eziqhelekileyo zihamba nge-10–40 L/min kwisebe ngalinye leraki kwi-1–4 bar, kodwa amanani achanekileyo avela kwiinkcukacha zobugcisa ze-cold-plate yeseva yakho kunye nenani lilonke leraki. Yila ngokusekelwe kwelona sebe liza kusebenza phantsi koxinzelelo olukhulu, uze wongeze umda wentloko yepompo ongange-20% wokulayisha isihluzo.

Uyalulinganisa njani ityhubhu yentsimbi engatyiwayo kumjikelo wokupholisa we-CDU?

Qala ngomlinganiselo wokuqhubeka ofunekayo kunye nesantya esijolisweyo (1.5–3 m/s), uze emva koko ufumane i-diameter yangaphakathi. Isahluli esiyi-10 L/min esisebenza nge-2 m/s sidinga malunga ne-ID eyi-9–10 mm. Hlala uqinisekisa ukuhla koxinzelelo kuyo yonke i-loop, kuquka i-manifold kunye nezixhobo zokudibanisa.

Yintoni umahluko phakathi kwe-CDU ne-chiller?

A Isipholisi ivelisa amanzi abandayo eziko; a I-CDU Ihleli kufutshane nee-racks kwaye isebenzisa i-heat exchanger ukwahlula loo loop yesakhiwo kwi-loop ye-coolant ebhidanisayo. Iipayipi ze-CDU zezona zichukumisa ngokwenene ulwelo olukwicala le-server.

Ngaba kufuneka usebenzise imibhobho eqinileyo okanye imibhobho egobekayo kuxhumano lwe-CDU?

I-stainless steel e-weldwe ngokuqinileyo kwi-orbital ilungele kakhulu imibhobho esisigxina kunye nokuqinisekisa ukungavuzi. Sebenzisa umbhobho ogobekayo kuphela kwiindawo zokwahlula ingxolo (kwiindawo apho kuphuma khona ipompo, kwizinto ezihambayo), kwaye ukhethe umbhobho olungiselelwe ikhemikhali kunye nobushushu be-coolant yakho.

Zeziphi iziqinisekiso ezisebenzayo kwimibhobho ye-CDU coolant?

Izalathiso eziqhelekileyo ziquka i-ASTM A312/A789 yee-tubing, i-ASME BPE yee-loops ezicocekileyo kakhulu, kunye ne-SEMI F57 yeemfuno zokucoca ukhuko. Chaza igrade echanekileyo, inombolo yobushushu, kunye nekhilasi yokucoca kwi-odolo yakho yokuthenga.

Imibhobho ye-CDU kufuneka ihlolwe okanye ihlanjwe kangaphi?

Hlola amadibaniselwano neetepu ezivuzayo xa kuqaliswa ukusebenza, uze uphinde wenze oko rhoqo kwikota yonyaka emva koko. Khupha amanzi uze uphinde wenze i-passivation ukuba umlinganiselo wokuhambisa umbane okanye wezinto ezingamathontsi awungena kwimigangatho — ngesiqhelo kube kanye ngonyaka kwinkonzo yamanzi e-DI, kwaye kwangoko ukuba ubona ukurusa.
