Graphite daim ntawv paub
Graphite ntawv yog ib hom tshiabthermal conductionthiabkub dissipationcov khoom siv, uas tuaj yeem ua cua sov sib npaug hauv ob qho kev qhia, tiv thaiv cov khoom siv hluav taws xob thiab cov khoom siv, thiab txhim kho kev ua haujlwm ntawm cov khoom siv hluav taws xob. Nrog rau kev nrawm ntawm kev kho dua tshiab ntawm cov khoom siv hluav taws xob thiab kev xav tau ntau ntxiv rau kev tswj xyuas hluav taws xob ntawm mini,kev koom ua ke siabthiabkev ua haujlwm siabcov khoom siv hluav taws xob, peb lub tuam txhab tau tsim lub tshuab hluav taws xob tshiab rau cov khoom siv hluav taws xob, uas yog, cov tshuaj tshiab rau graphite heat dissipation. Qhov kev daws teeb meem tshiab graphite no muaj qhov zoo ntawm kev ua haujlwm siab kub dissipation, kev ua haujlwm me me,lub teeb nyhav, cov khoom siv hluav taws xob sib xyaw ua ke raws li ob qho kev qhia, tshem tawm "qhov chaw kub", tiv thaiv cov khoom siv hluav taws xob thiab cov khoom siv, thiab txhim kho kev ua haujlwm ntawm cov khoom siv hluav taws xob. Lub ntsiab siv ntawm graphite ntawv yog raws li nram no: Nws yog siv rau hauv phau ntawv computer, lub zog siab LED teeb pom kev zoo, lub vaj huam sib luag tiaj tiaj, lub koob yees duab digital, xov tooj ntawm tes thiab cov cuab yeej pabcuam tus kheej. Thaum tshav kub kub dissipation txoj cai ntawm graphite fin tshav kub dissipation tshuab yog raws li nram no: Lub luag haujlwm tseem ceeb ntawm daim ntawv graphite yog los tsim kom muaj thaj chaw zoo heev uas cov cua sov hloov mus thiab tshem tawm los ntawm qhov nruab nrab cua txias sab nraud. Graphite heat sink yog los ntawm kev sib faib ntawm cov cua sov hauv ob sab ntawm lub dav hlau, thiaj li hloov tau cov cua sov kom zoo, kom ntseeg tau tias cov khoom ua haujlwm hauv qhov kub thiab txias. Cov yam ntxwv ntawm cov khoom: qhov saum npoo tuaj yeem ua ke nrog hlau, yas, nws tus kheej nplaum thiab lwm yam ntaub ntawv, ntau tus qauv tsim thiab kev xav tau. Zoo heev thermal conductivity: 150-1200w / mk, zoo dua li cov hlau. Lub teeb yuag, lub ntiajteb txawj nqus tsuas yog 1.0-1.3, mos, yooj yim rau kev khiav lag luam. Tsawg thermal tsis kam. Cov xim yog dub. Thickness: 0.012-1.0mm, nplaum: 0.03mm, thermal conductivity: dav hlau conduction: 300-1200w / mk, ntsug conduction: 20-30w / MKkub tsis kamKub: 400 ℃. Tsawg thermal kuj: 40% qis dua txhuas thiab 20% qis dua tooj liab; Lub teeb yuag: 25% sib dua li txhuas thiab 75% sib dua li tooj liab. Thiab raws li qhov xav tau ntawm cov neeg siv khoom los ua txhua hom kev txiav. Volume Resistivity ASTM D257Ω / CM 3.0 ~ 10; Hardness ASTM D2240 ntug A＞80
