Cov ntaub ntawv dab tsi nrog kev ua haujlwm thermal zoo dua?

1. Thermal roj

Thermally ua raws silicone grease yog dav siv cov kev coj ua nruab nrab tam sim no. Nws yog tus ester - xws li cov khoom tsim los ntawm cov txheej txheem tshwj xeeb nrog cov roj silicone raws li cov khoom siv raw thiab fillers xws li thickeners. Cov tshuaj muaj qee yam viscosity thiab tsis muaj qhov pom tseeb. Kev ua haujlwm kub ntawm thermal conductive silicone grease feem ntau - 50°C rau 220°C. Nws muaj cov cua sov condal zoo, kev kub siab kuj, kev laus tsis kam thiab cov yam ntxwv tsis muaj dej. Thaum lub sijhawm ua cua sov dissipation txheej txheem ntawm lub cuab yeej, tom qab tau ua kom sov rau qee lub xeev, ua kom muaj cov cua sov ua kom sov, yog li ua kom sov sov.

2. Thermal silica gel

Thermally ua raws li Silica Gel kuj tau ua los ntawm kev ntxiv cov ntaub ntawv raw tshuaj silicone thiab siv tshuaj lom duab. Txawm li cas los xij, tsis zoo li thermal silicone roj, muaj qee cov tshuaj uas muaj kuab tshuaj ntxiv rau nws, yog li cov ua tiav thermal silicone muaj qee yam kev quab yuam. Qhov loj tshaj plaws tseem ceeb ntawm kev coj ua silicone yog tias nws yog qhov nyuaj tom qab solidification yog me ntsis qis dua li ntawm thermally qhuab qhia silicone roj. Ps. Thermally ua raws silicone yog ib qho yooj yim rau "tus ntaus ntawv thiab nws tsis pom zoo kom raug xaiv raws li cov qauv cua sov thiab cov qauv cua sov.

3. Thim Thermally coj Silicone Sheet

Muag silicone thermal rwb thaiv tsev gaskets muaj zoo thermal conductivity thiab siab - rwb thaiv tsev. Lub thermal conductivity ntawm gaskets tsim los ntawm Aochuan ranges los ntawm 1 txog 8W / MK, thiab qhov siab tshaj plaws hluav taws xob puas yog siab dua 10kV. Nws yog ib qho pauv hloov rau thermal kev coj ua silicone cov khoom siv muaj roj. Cov khoom nws tus kheej muaj qee qib ntawm kev yoog tau zoo, uas haum xim zoo ntawm cov ntawv muaj zog lossis ua kom tiav cov cua sov zoo tshaj plaws thiab cua sov dissipation. Nws ua tau raws li cov kev xav tau ntawm kev lag luam hluav taws xob rau tshav kub - Ua cov ntaub ntawv. Nws yog qhov hloov chaw rau tshav kub - Ua si silicon roj thermal yog cov khoom lag luam zoo tshaj plaws rau cov tshuab cua txias. Hom khoom no tuaj yeem txiav ntawm yuav, uas yog qhov tseem ceeb rau kev tsim khoom thiab khoom txij nkawm.

Lub thickness ntawm silicone thermal rwb thaiv tsev ncoo sib txawv los ntawm 0.5 hli txog 10 hli. Nws yog qhov tshwj xeeb tsim tawm rau cov txheej txheem tsim ntawm kev siv cov sib txawv los hloov cua sov. Nws tuaj yeem sau qhov sib txawv, ua kom tiav cov cua sov hloov ntawm cov cua sov feem thiab cov cua sov dissipation feem, thiab tseem ua lub luag haujlwm ntawm kev nqus tawm, rwb thaiv tsev thiab sib khi. , tuaj yeem ua tau raws tus qauv tsim nyog yuav tsum muaj cov miniaturization thiab ultra - thinning ntawm cov khoom siv sib raug zoo. Nws yog cov khoom siv tshiab nrog kev tsim khoom siv tau zoo thiab siv tau. Cov nplaim taws retardant thiab fireproof ua tau zoo raws li qhov yuav tsum tau ntawm U.l 94V - 0, thiab tau raws li EU SGS kev tiv thaiv ib puag ncig.

4. Cov hluavtaws graphite flakes

Qhov no zoo ntawm cov cua sov conduction nruab nrab yog qhov tsawg dua, thiab feem ntau yog siv rau qee yam khoom uas tsim kom muaj cua sov tsawg dua. Nws tau txais graphite Composite cov khoom siv tshuaj, nws muaj cov nyhuv kub heev, thiab haum rau cua sov dissipation system ntawm chips hluav taws xob, CPU thiab lwm yam khoom. Thaum ntxov Intel Boxed P4 cov txheej txheem, cov khoom siv txuas rau hauv qab ntawm lub taub dej sov yog ib graphite thom yog graphite thom dawb hu ua m751. "Uproot" CPU los ntawm nws lub hauv paus. Ntxiv rau cov saum toj no - ua cov tshav kub sib txawv - ua cov xov xwm yooj yim - ua cov gaskets), thiab lwm yam ntxiv rau kev ua si, tab sis cov khoom lag luam no tsis tshua muaj kev lag luam.
