Graphene tshav kub dissipation txheej
Nrog rau kev tsim hluav taws xob circuits thiab kev sib txuas lus thev naus laus zis, cov khoom siv hluav taws xob thiab cov chips ua haujlwm tau zoo tas li txhim kho nyob rau hauv cov kev taw qhia ntawm miniaturization, lub teeb yuag, thiab kev ua haujlwm siab.
Qhov luaj li cas ntawm cov cuab yeej yog maj mam shrinking, thiab qhov kub siab uas tsim los ntawm cov cua sov dissipation tsis zoo tsuas yog ua rau cov cuab yeej khiav tsis ruaj khov, ua rau lub neej ua haujlwm luv, thiab txawm tias hlawv tawm qee qhov. Yog li ntawd, cov cua kub dissipation yog ib qho kev txwv tsis pub muaj kev txhim kho ntawm cov khoom siv hnyav thiab kev ua haujlwm siab. Kev ua lag luam tam sim no tsuas yog daws qhov teeb meem kub dissipation ntawm cov khoom siv hluav taws xob nrog cov cua kub dissipation. Txawm li cas los xij, cov khoom siv hluav taws xob fin yog txwv los ntawm qhov ntim thiab qhov zoo, thiab cov khoom siv hluav taws xob ua kom sov yog txwv, thiab nws nyuaj rau ua kom tau raws li qhov xav tau ntawm cov hluav taws xob hluav taws xob siab.
Kev tswj cov cua kub yog qhov tseem ceeb ntawm cov khoom siv hluav taws xob hauv hluav taws xob, thiab tau txais kev saib xyuas ntau dua nrog kev txhim kho txuas ntxiv ntawm kev sib dhos ceev thiab kev sib koom ua ke. Muaj ntau qhov kev siv hluav taws xob qis qis, suav nrog cov neeg siv khoom siv hluav taws xob, tsheb, chaw nres tsheb hauv paus, servers, thiab cov chaw khaws ntaub ntawv, nrog rau qhov chaw ua lag luam ntau pua lab. Raws li kev kwv yees ntawm Lub Tsev Haujlwm Saib Xyuas Kev Lag Luam Yav Tom Ntej, qhov sib xyaw ua ke txhua xyoo kev loj hlob ntawm kev lag luam kub dissipation yuav ncav cuag 8% los ntawm 2018 txog 2023, thiab kev lag luam loj yuav tsum loj hlob los ntawm 149.7 billion yuan hauv 2018 txog 219.9 billion yuan hauv 2023. . ,
Txawb xov tooj cua kub dissipation suav txog li 7% ntawm tag nrho cov nplai ntawm kev lag luam kub dissipation. Hauv 2018, nws yog kwv yees li 10 billion yuan. Txawm hais tias qhov kev faib ua feem tsawg, yav tom ntej, uas tau tsav los ntawm kev txhim kho txuas ntxiv ntawm 5G ntse terminals, lub xov tooj cua txias ua lag luam yuav tsum muaj kev loj hlob siab, thiab qhov nruab nrab txhua xyoo kev loj hlob ntawm 2018 txog 2022 yuav tsum ncav cuag 26%. Tsis tas li ntawd, kev tsim kho loj ntawm 5G kev lag luam hauv paus chaw nres tsheb kuj tseem xav tias yuav tsav qhov kev nthuav dav ntawm kev lag luam kub dissipation rau semi-khoom tuag-cam khwb cia vaj tsev thiab cov paib paib. Nyob rau hauv cov nqe lus ntawm kev loj hlob mus sij hawm ntev tiam sis, nrog rau kev nce nyob rau hauv network tsheb coj los ntawm 5G, lub server txias kev lag luam yuav txuas ntxiv mus. Nyob rau hauv qhov kev pom ntawm qhov teeb meem loj ntawm cov cua kub dissipation, cov kws tshawb fawb tau siv cov txheej txheem kub dissipation rau hauv hluav taws xob los daws qhov teeb meem kub dissipation. General tshav kub-dissipating txheej yog raws li nyob rau hauv polymers, thiab ib co hlau fillers nrog zoo thermal conductivity yog ntxiv, feem ntau nrog rau cov tsoos kub, tooj liab, txhuas, thiab ib co non-metallic fillers nrog high thermal conductivity xws li txhuas nitride thiab silicon nitride. , Alumina, Magnesium Oxide, thiab lwm yam.
Vim tias graphene muaj thermal conductivity siab heev thiab muaj zog emissivity, thermal conductivity tuaj yeem ncav cuag 5300 W / m·K, thiab emissivity coefficient yog siab dua 0.95. Yog li ntawd, graphene tshav kub-dissipating xim npaj los ntawm graphene yog pleev xim rau tom qab ntawm lub substrate, lub thermal tawg coefficient ntawm lub substrate nto yuav ua tau zoo heev (txog li 0.9), thiab tshav kub exchanger efficiency ntawm cov khoom nto. tuaj yeem txhim kho tau zoo. Nyob rau tib lub sijhawm, graphene tshav kub dissipation txheej tuaj yeem tshem tawm cov cua sov los ntawm qhov chaw ntawm lub substrate nyob rau hauv daim ntawv ntawm cov hluav taws xob infrared, txhim kho cov nyhuv ntawm cov cua sov, thiab txo qhov kub thiab txias ntawm cov khoom.
Ntxiv rau qhov zoo tshaj plaws hluav taws xob hluav taws xob hluav taws xob hluav taws xob, graphene tshav kub dissipation coatings kuj muaj cov adhesion zoo, huab cua tsis kam thiab ntsev tsuag tsis kam, zoo kub tsis kam, thiab nplua nuj siv scenarios. Lawv tuaj yeem siv dav hauv cov ntawv thov loj. Fais fab LED radiator, CPU radiator, muaj cov khoom cua sov dissipation, nws pib qhov chaw tshav kub dissipation thiab lwm yam teb.
Vim hais tias muab tub lim graphene muaj cov thermal conductivity zoo, tiv thaiv corrosion thiab mechanical zog, peb lub tuam txhab tuaj yeem kho thiab txhim kho cov qauv tsim raws li qhov tshwj xeeb daim ntawv thov scenarios thiab siv cov kev xav tau ntawm cov txheej, thiaj li ua kom nws cov cua kub dissipation, tiv thaiv corrosion thiab tiv thaiv. corrosion kuj muaj nyob rau hauv ntau yam txheej. Kev ua tau zoo heev xws li hnav tsis kam. Cov khoom siv graphene nws tus kheej yog tsis muaj tshuaj lom thiab tsis muaj teeb meem, thiab tuaj yeem txo lossis hloov kev siv cov khoom siv inorganic nyob rau hauv cov txheej txheem ib txwm siv, txhim kho cov nyhuv tshav kub thiab txo cov nqi. Graphene tshav kub dissipation xim yog tsim rau tshuaj tsuag ntawm magnesium alloy thiab aluminium alloy radiators los txhim kho cov cua kub dissipation nyhuv ntawm radiator.
