Cov khoom siv thermal rau 5G
Cov ntaub ntawv thermal hauv 5G era tau txais ntau dua thiab tseem ceeb, ib qho ntawm cov yam ntxwv tseem ceeb ntawm 5G era yog qhov tseem ceeb ntawm cov cua sov. Raws li kev siv hluav taws xob ntawm cov khoom siv hluav taws xob nce ntxiv, cov kev xav tau rau cov cua sov dissipation yog nruj dua, thiab kev siv cov khoom siv thermal kuj yog dav dua.
Cov kev daws teeb meem ntawm cov khoom siv hluav taws xob yog cov khoom siv hluav taws xob feem ntau yog cov cua sov dissipation thiab natural heat dissipation.
Active heat dissipation yog qhov yuav tsum tau ua kom sov dissipation nrog dynamic Cheebtsam, xws li cua yuam kom txias, indirect kua txias thiab ncaj qha kua txias. Nws feem ntau yog siv nyob rau hauv high-power thiab kuj loj hluav taws xob khoom.
Ntuj tshav kub dissipation yog ib txoj kev tshav kub dissipation yam tsis muaj hwj chim hais. Nws tsuas yog tso siab rau cov khoom siv tsis muaj zog thiab cov khoom siv rau kev hloov hluav taws xob. Nws yog dav siv nyob rau hauv lub xov tooj ntawm tes, ntsiav tshuaj, smart watches, sab nraum zoov chaw nres tsheb, thiab lwm yam. Natural heat dissipation yog lub ntsiab cua sov dissipation txoj kev ntawm cov khoom siv hluav taws xob. Thaum tshav kub kub dissipation cov ntaub ntawv siv mas muaj xws li kub-conductive interface cov ntaub ntawv, graphite pieces, kub yeeb nkab / VC, thiab lwm yam.
1. Cov khoom siv thermal interface
Cov khoom siv hluav taws xob sib txuas yog qhov tseem ceeb ntawm kev ua haujlwm siab thermal conductivity ntawm cov khoom siv thermal thiab lub radiator. Nws yog tsuas yog siv los ntawm qhov system thermal interface. Los ntawm kev sau cov ntxhib ua ke saum npoo, cov cua sov coefficient yog siab dua li cov khoom siv hluav taws xob sib txuas uas siab dua li huab cua. Lub tshav kub dissipation efficiency. Cov khoom siv thermal conductivity feem ntau muaj xws li kub-ua silicon roj, thermal conductivity, thermal conductivity hloov khoom, thermal conductivity (dej), thermal daim kab xev, thermal gel, thiab lwm yam.
2. Graphite
Multi-layer graphite yog tam sim no mainstream tshav kub dissipation txoj kev. Graphite yog ib qho zoo thermal conductivity, uas tshaj ntau yam khoom siv hlau xws li hlau, hlau, thiab txhuas. Lub hauv paus ntsiab lus ntawm kev ua haujlwm ntawm graphite ntsiav tshuaj yog siv nws cov yam ntxwv ntawm thermal conductivity zoo nyob rau hauv kab rov tav (kev ua haujlwm zoo graphite ntawv thermal conductivity tuaj yeem ncav cuag 1500-1800W / m · k, thiab cov ntshiab tooj liab thermal conductivity yog 380W / m. · K, qhov siab conduction coefficient yog conducive rau diffusion ntawm tshav kub), uas yuav sai sai txo qhov kub ntawm lub cua sov caij nyob rau hauv kev ua hauj lwm ntawm cov khoom siv hluav taws xob, ua kom kub ntawm cov khoom siv hluav taws xob txawm uniformly, thiab txhim kho kev ruaj ntseg thiab kev pab cuam. lub neej ntawm cov khoom siv hluav taws xob. Graphite pieces yog siv dav hauv cov neeg siv khoom siv hluav taws xob hluav taws xob kub dissipation.
Graphene yog ib tug ob-dimensional siv lead ua uas yog tev los ntawm graphite cov ntaub ntawv thiab muaj xws li carbon atoms nrog tsuas yog ib txheej ntawm atomic thickness. Graphene cov ntaub ntawv kuj suav hais tias yog cov khoom cua txias uas muaj zog cua sov-ua cov yam ntxwv, ceev cov cua kub dissipation yam ntxwv (nrog cua convection), thiab lub teeb thiab yooj. Vim tus nqi siab, graphene tseem tsis tau siv rau hauv qhov loj.
3. Thaum tshav kub kub yeeb nkab thiab Vapor chamber
Cov yeeb nkab cua sov thiab Vapor Chamber yog cov khoom siv hluav taws xob uas siv los ntawm cov khoom siv hluav taws xob. Lub thermal coefficient yog siab heev thiab dav siv nyob rau hauv high-power lossis high-integrated electronic khoom.
Lub hauv paus ntsiab lus ntawm kev ua haujlwm ntawm cov yeeb nkab cua sov thiab VC yog raws li cov theem hloov. Ob lub kav dej kub thiab VC yog lub tshuab nqus tsev, thiab qhov nruab nrab nruab nrab (xws li dej) tau ntim. Cov khoom siv hloov pauv theem hauv cov kab noj hniav hloov ntawm cov kua mus rau cov pa nqus cua sov. Thaum cov roj kov cov cheeb tsam nrog qhov kub thiab txias, cov kua yog condensed kom tso cua sov, Cov kua los ntawm cov qauv capillary ntws rov qab mus rau qhov chaw cua sov, circulating thiab tshem tawm cov cua sov. Cov yeeb nkab cua sov tsuas yog ib qho kev taw qhia "linear" zoo thermal conductivity, thiab VC yog sib npaug rau kev hloov kho los ntawm "kab" mus rau "nto", uas tuaj yeem kis tau cov cua sov mus rau ib puag ncig, thiab VC muaj thaj tsam loj ntawm cov phaj kub, uas tuaj yeem npog ntau qhov chaw sov. Yog li ntawd, VC muaj cov cua kub dissipation ntau dua li cov kav dej kub.
Sinda Thermal yog cov kws tshaj lij thermal, peb tab tom muab ntau cov kev daws teeb meem thermal thiab cov dab dej kub rau cov neeg siv khoom thoob ntiaj teb, peb tuaj yeem tsim qhov kev ua tau zoo ntawm cov dab dej kub thiab tsim khoom hauv tsev, peb lub Hoobkas muaj ntau tshaj 100 tus neeg ua haujlwm thiab ntau yam khoom siv thiab cov khoom siv. Thov hu rau peb dawb yog tias koj muaj kev xav tau thermal.
