Thermal Challenge ntawm nti
Lub zog siv los ntawm cov khoom siv hluav taws xob tsim hluav taws xob, uas yuav tsum tau muab tshem tawm ntawm cov khoom siv, tab sis yuav ua li cas kom ua tiav qhov no yog ib txoj haujlwm nyuaj. Raws li qhov ceev ntawm transistors nce, qhov no yuav nyuaj dua.
Cov ntaub ntawv thiab tsim lawv tus kheej muaj peev xwm txhim kho, vim tias lawv tuaj yeem nqa cov cua sov ntau dua los ntawm cov khoom siv hluav taws xob dissipation. Qhov kev sib tw yog tias tshwj tsis yog peb siv cov servers loj, qhov chaw thermal nyob ib puag ncig cov cuab yeej no tsawg heev. Koj yuav tsum xav txog kev txhim kho cov khoom siv, kev siv ntse ntawm qhov chaw thermal nyob ib puag ncig cov chips, ntim, lossis PCBs. Qhov koj xav ua tiag tiag yog txhim kho cov conductivity thiab kub hloov pauv.
Thaum tshav kub kub tuaj yeem khiav los ntawm sab saum toj ntawm lub pob thiab tom qab ntawd nkag mus rau hauv lub dab dej kub, lossis raug xa tawm mus rau hauv qab thiab nws cov PCB txuas. Thaum qhov chaw txwv, tej yam yuav nyuaj dua. Nyob ntawm qhov tsim tshwj xeeb, lub hom phiaj no tuaj yeem ua tiav hauv ntau txoj kev. Piv txwv li, hauv smartphones, kev siv cov yeeb yaj kiab uas muaj suab nrov xws li graphite lossis graphene zaj duab xis yog qhov tshwm sim vim qhov tsawg tshaj plaws ntawm qhov system ntim thiab ua kom muaj cua sov zoo. Nyob rau hauv lub tshav pob ntawm infrastructure, kev siv ntawm active thiab passive 3D soaking daim hlau yuav ua tau hauj lwm nyob rau hauv ib tug ntau ntawm pua pua ntawm watts.
Ntawm ib lub nti, peb ua lub sijhawm thiab lub zog pov thawj ntawm qib netlist. Nyob rau hauv cov ntsiab lus ntawm 3D-IC, qhov no yuav ua tsis tau zoo, yog li cov yam ntxwv ntawm cov chips los ntawm thermal qauv, thiaj li yuav nkag siab txog txhua yam geometric nthuav dav hauv cov nti. Thaum kawg, nws muab cov qauv tsim thiab ntim khoom, thiab qee cov qauv chip yog tsim los ntawm txoj kev no.
Ntau cov chips ntsib cov teeb meem thermal, thiab kev daws qhov teeb meem no tsis yooj yim. Peb tuaj yeem tsim thiab tsim cov chips zoo kawg, tab sis lawv yuav yaj. Qhov no tsis yog kev txwv kev tsim khoom, thiab tsis yog qhov kev txwv tsim. Qhov no yog ib qho kev txwv ntawm lub cev, thiab peb tsis tuaj yeem tawm cua sov ntxiv. Txawm hais tias cov kev daws teeb meem tshwj xeeb tuaj yeem siv rau hauv qee yam kev siv, feem ntau cov khw muag khoom yuav tsum nrhiav txoj hauv kev los ua ntau dua nrog cov peev txheej tsawg, uas txhais tau tias ua haujlwm ntau dua ib watt. Tus nqi cuam tshuam nrog qhov no ntau dua li cov kev daws teeb meem yav dhau los.
