Thaum tshav kub kub dissipation cov ntaub ntawv: nkag siab cov thermal conductive graphite cua sov dab dej
Nrog rau txoj kev loj hlob ntawm cov neeg siv khoom siv hluav taws xob mus rau ultra-nyias, ntse thiab multifunctional, cov khoom siv hluav taws xob ntau ntxiv thiab cov khoom nyias nyias tau nthuav tawm qhov teeb meem ntawm cov cua sov li cas. Vim tias nws cov khoom muaj txiaj ntsig zoo hauv thermal conductivity, thermally conductive graphite nplooj tau txais ntau thiab ntau cov xim thiab tau siv dav hauv cov xov tooj ntse, ultra-thin PCs thiab LED TVs.
Vim nws qhov tshwj xeeb crystal grain orientation, cov thermally conductive graphite daim ntawv ua cua sov uniformly nyob rau hauv ob txoj kev (XY axis thiab Z-axis). Cov txheej txheej txheej tuaj yeem hloov kho kom zoo rau qhov kev hloov pauv ntawm cov cuab yeej tom qab ua tiav. Cov qauv siv lead ua tshwj xeeb thiab cov txheej txheem ua kom nws tuaj yeem muab cov thermal rho tawm thiab tiv thaiv cov khoom siv hluav taws xob thiab cov khoom siv thaum ua cov khoom siv hluav taws xob zoo sib xws, uas ua rau muaj txiaj ntsig zoo ntawm cov khoom siv hluav taws xob.
Dab tsi yog thermal graphite ntawv?
Thermally conductive graphite sheet yog cov khoom siv hluav taws xob tshiab thiab cov khoom siv hluav taws xob cua sov uas ua rau cov cua sov sib xws hauv ob qho kev qhia, tiv thaiv cov cua sov thiab cov khoom siv, thiab txhim kho kev ua haujlwm ntawm cov khoom siv hluav taws xob. Nrog rau kev kho dua tshiab ntawm cov khoom siv hluav taws xob, kev ua kom nrawm, mini, kev sib koom ua ke, thiab cov khoom siv hluav taws xob ua tau zoo yog qhov xav tau kev tswj xyuas qhov kub thiab txias.
Cov tshuaj graphite tshiab no muaj qhov ua kom sov siab ua haujlwm, hneev taw me me thiab lub teeb yuag. Cov xim feem ntau yog xim dub, thiab cov khoom siv yog ntuj graphite tom qab kev ua haujlwm zoo, thiab cov thermal conductivity siab li 1500W / MK nyob rau hauv txoj kab rov tav. Feem ntau siv nyob rau hauv IC, CPU, MOS, LED, lub dab dej kub, LCD-TV, laptop computers, khoom siv sib txuas lus, wireless keyboards, DVDs, handheld pab kiag li lawm, thiab lwm yam.
Kev faib tawm ntawm thermal conductive graphite ntawv:
Graphite flakes muab faib ua ntuj graphite flakes thiab dag graphite flakes!
Ntuj graphite tshav kub dissipation zaj duab xis muaj siab thermal conductivity, yooj yim tsim, yooj, tsis muaj roj thiab kua permeability, graphite chips tsis laus thiab embrittlement, haum rau feem ntau cov tshuaj, thiab cov thermal conductivity yog 700 ~ 1200W / mk Qhov tsis zoo ntawm ntuj graphite daim ntawv yog tias nws tsis tuaj yeem nyias dhau. Feem ntau, cov khoom tiav thinnest yog 0.1 hli tuab. Yog li ntawd, kev lag luam sib faib ntawm ntuj graphite tau qis dua thiab qis dua. Nyob rau tib lub sij hawm, vim cov yam ntxwv ntawm tej yam ntuj tso graphite nws tus kheej, lub tshav kub dissipation nyhuv ntawm ntuj graphite kuj tsis muaj zog.
Artificial graphite tuaj yeem ua kom nyias nyias, thiab cov nyhuv tshav kub yog qhov zoo heev. Lub thermal conductivity yog 1000 ~ 1500W / mk, uas yog feem ntau xav txog nyob rau hauv lub ceev kub dissipation ceev, tab sis tus nqi ntawm cov khoom graphite kuj yog siab. Raws li kev lag luam xov tooj ntawm tes tau nce mus nrhiav qhov zoo, cov nplooj ntawv hluavtaws graphite kuj nrov.
Lub hauv paus ntsiab lus ntawm Graphite Sheet Thaum tshav kub kub Dissipation:
Ib qho kev tswj xyuas thermal yog tsim los ntawm cov khoom siv cua txias sab nraud, lub tshuab hluav taws xob thiab cov seem thermal. Siv cov khoom siv xov tooj ntse ua piv txwv:
1. Thaum tshav kub kub hloov mus rau hauv lub casing thiab thav duab los ntawm lub dav hlau ntawm thermally conductive graphite ntawv;
2. Qhov saum npoo ntawm cov ntawv thermally conductive graphite txhim khu cov nyhuv infrared;
3. Cov ntawv thermal conductive graphite nthuav dav lub dav hlau tshav kub dissipation cheeb tsam thiab sai sai dissipates lub tshav kub dissipation point.
Kev ua thiab tsim cov ntawv thermal conductive graphite: Yuav kom ua tau zoo dua rau qhov chaw undulating ntawm cov khoom siv hluav taws xob thiab cov khoom siv hluav taws xob, nws yog ib qho tsim nyog yuav tau ua qee yam ntawm cov ntawv thermally conductive graphite. Cov txheej txheem tseem ceeb ntawm kev ua haujlwm yog:
1. Adhesive: Rau lub hom phiaj kom zoo dua adhesion rau IC thiab Circuit Court boards, cov nplaum yog ua tiav nyob rau saum npoo ntawm thermal conductive graphite ntawv;
2. Rov qab zaj duab xis: Hauv qee qhov kev tsim hluav taws xob uas xav tau kev rwb thaiv tsev lossis hluav taws kub, txhawm rau txhim kho kev ua haujlwm zoo dua, cov yeeb yaj kiab rov qab tau ua tiav ntawm cov ntawv graphite.
Peb tuaj yeem xaiv cov txheej txheem tsim nyog raws li qhov xav tau tiag tiag ntawm cov khoom.
