Graphite thermal sheets tau dhau los ua qhov tseem ceeb hauv ntau qhov kev lag luam vim lawv cov thermal conductivity zoo thiab lwm yam khoom zoo. Raws li tus neeg xa khoom ntawm Graphite Thermal Sheets, Kuv feem ntau tau txais kev nug txog lawv lub neej. Hauv qhov blog no, kuv yuav delve rau hauv cov xwm txheej uas cuam tshuam ntev npaum li cas graphite thermal nplooj ntawv kawg thiab muab qee qhov kev nkag siab los pab koj ua qhov zoo tshaj plaws ntawm cov khoom no.
Nkag siab Graphite Thermal Sheets
Ua ntej sib tham txog lawv lub neej, nws yog ib qho tseem ceeb kom nkag siab tias graphite thermal ntawv yog dab tsi thiab vim li cas lawv thiaj li nrov. Graphite thermal ntawv yog tsim los ntawm siab - purity graphite cov ntaub ntawv. Lawv paub txog lawv qhov siab hauv - dav hlau thermal conductivity, uas tuaj yeem hloov cov cua sov kom deb ntawm tshav kub - tsim cov khoom. Cov nplooj ntawv no feem ntau siv hauv cov khoom siv hluav taws xob, xws li smartphones, laptops, thiab LED teeb pom kev zoo, nrog rau cov khoom siv hauv kev lag luam thiab kev siv tsheb. Koj tuaj yeem nrhiav cov ncauj lus kom ntxaws ntxiv txog Graphite Thermal Sheet ntawm peb lub vev xaib.
Cov yam ntxwv cuam tshuam rau lub neej ntawm Graphite Thermal Sheets
1. Kev ua haujlwm kub
Ib qho tseem ceeb tshaj plaws uas cuam tshuam rau lub neej ntawm graphite thermal ntawv yog qhov ua haujlwm kub. Graphite muaj cov ntsiab lus melting siab, tab sis tsis tu ncua raug rau qhov kub siab heev tuaj yeem ua rau muaj kev hloov pauv hauv cov graphite. Thaum kub siab, cov graphite yuav pib oxidize, uas tuaj yeem ua rau degradation ntawm nws thermal conductivity thiab txhua yam khoom. Piv txwv li, nyob rau hauv ib lub qhov cub uas muaj qhov kub thiab txias tuaj yeem ncav cuag ntau pua degrees Celsius, graphite thermal ntawv yuav muaj kev cuam tshuam sai dua piv rau qhov chaw txias dua li lub chaw ua haujlwm li niaj zaus - siv lub laptop.
2. Chemical Ib puag ncig
Cov tshuaj ib puag ncig uas cov graphite thermal ntawv ua haujlwm kuj ua lub luag haujlwm tseem ceeb.

Piv txwv li, muaj zog oxidizing tus neeg sawv cev tuaj yeem tawm tsam cov qauv graphite, ua rau nws tawg dhau sijhawm. Nyob rau hauv ib lub chaw ua tshuaj uas muaj corrosive tshuaj nyob rau hauv cov huab cua los yog nyob rau hauv kev sib cuag nrog cov cuab yeej, graphite thermal daim ntawv lub neej yuav txo tau ho.
3. Mechanical Stress
Kev ntxhov siab, xws li khoov, ncab, lossis compression, tuaj yeem cuam tshuam rau kev ncaj ncees ntawm graphite thermal ntawv. Graphite yog cov khoom siv tawv tawv, thiab kev ntxhov siab ntau dhau tuaj yeem ua rau tawg lossis tawg hauv daim ntawv. Thaum cov ntaub ntawv tawg, nws tuaj yeem nthuav tawm nyob rau hauv kev ntxhov siab ntxiv, ua rau tsis ua tiav ntawm daim ntawv thermal. Nyob rau hauv daim ntawv thov uas cov graphite thermal daim ntawv yuav raug kev vibrations los yog txav, xws li nyob rau hauv lub tsheb cav, tsim nyog mounting thiab kev txhawb nqa yog ib qho tseem ceeb kom txo tau cov neeg kho tshuab kev nyuaj siab.
4. Kev siv ntau zaus
Qhov ntau zaus siv cov graphite thermal ntawv, qhov luv nws lub neej yuav zoo li. Kev ua haujlwm tsis tu ncua txhais tau tias kev hloov pauv mus tas li thiab muaj peev xwm raug rau ntau yam kev ntxhov siab. Piv txwv li, chav neeg rau zaub mov nrog siab - kev ua haujlwm servers khiav 24/7 yuav xav tau graphite thermal sheets uas tuaj yeem tiv taus ntev - lub sijhawm, siab - siv. Hauv cov xwm txheej zoo li no, cov ntawv thermal tej zaum yuav tsum tau hloov ntau zaus piv rau cov khoom siv tsawg dua -.
