Graphite ntawv
Synthetic graphite ntawv, tseem hu ua Artificial Graphite Sheet, yog ib hom tshiab ntawm cov khoom siv thermal interface ua los ntawm polyimide. Nws txais cov qib siab carbonization, graphitization thiab calendering txheej txheem los tsim ibthermally conductive zaj duab xisnrog tshwj xeeb lattice orientation los ntawmhigh-temperature sinteringntawm 3000 ° C. Nrog rau kev kho dua tshiab ntawm cov khoom siv hluav taws xob, cov khoom siv hluav taws xob loj zuj zus tuaj, cov khoom siv hluav taws xob sib xyaw ua ke thiab kev ua haujlwm siab, ua rau muaj ntau qhov kev tswj xyuas cov cua sov dissipation xav tau.Nta ntawm hluavtaws graphite ntawv:
* Zoo heev thermal conductivity * Lub teeb yuag * Yooj yim thiab yooj yim los txiav. (thov rov khoov dua) * Tsawg thermal tsis kam * Tsawg kub tsis kam nrog cov ntawv hloov pauv graphite * Tsawg repulsion thiab yooj yim kom cov khoom zoo tom qab txuasDaim ntawv thov ntawm hluavtaws graphite ntawv:
Cov ntaub ntawv thermal interface yog tsim los siv rau hauv cov ntawv thov uas xav tautxhim khu kev qha kev ua tau zoo, tsis tshua muaj kev tiv thaiv, lub neej ntev, tsis tshua muaj txij nkawm thiabsiab thermal conductivity. Cov ntaub ntawv graphite hloov tau yog tuag-txiav kom paub tseeb tias haum thiab txo qis module-rau-module variation thaum sib dhos. Lub compressibility ntawm cov khoom txhim kho qhov chaw sib cuag, txo cov thermal impedance thiab tuaj yeem them rau 125μ ntawm flatness variation ntawm cov chaw sib cuag thaum lub dav hlau thermal conductivity txo qhov kub. Nrog kev nce ntawm cov tsheb tshiab zog,graphene ntawvyog dav siv nyob rau hauv aluminium ion roj teeb.
