Nyob rau hauv puas tau - evolving toj roob hauv pes ntawm thermal tswj kev daws teeb meem, graphite thermal sheets tau tshwm sim los ua ib qho kev ua si - hloov. Raws li tus neeg muag khoom ntawm graphite thermal ntawv, kuv zoo siab los qhia txog cov haujlwm thiab kev siv ntawm cov ntaub ntawv zoo kawg li no.
1. Taw qhia rau Graphite Thermal Sheets
Graphite thermal ntawv yog tsim los ntawm siab - purity graphite cov ntaub ntawv. Lawv muaj cov khoom tshwj xeeb ntawm lub cev thiab tshuaj lom neeg uas ua rau lawv zoo tagnrho rau kev tswj xyuas thermal. Graphite muaj qib siab ntawm crystallinity, uas tso cai rau nws ua kom sov tau zoo nyob rau hauv - dav hlau kev taw qhia. Cov nplooj ntawv no feem ntau yog nyias, hloov tau, thiab tuaj yeem txiav tau yooj yim thiab zoo li tus kom haum rau ntau yam khoom siv thiab cov khoom siv.
2. Thaum tshav kub kub ua haujlwm
Ib qho ntawm cov haujlwm tseem ceeb ntawm graphite thermal ntawv yog kev ua kom sov. Hauv cov khoom siv hluav taws xob niaj hnub no, xws li smartphones, laptops, thiab siab - lub zog LED teeb, muaj cua sov ntau thaum ua haujlwm. Yog tias qhov cua sov no tsis zoo, nws tuaj yeem ua rau overheating, uas yuav ua rau kev ua haujlwm tsis zoo, txo lub neej, thiab txawm tias lub cev tsis ua haujlwm.
Graphite thermal ntawv ua raws li cov thermal conductors zoo heev. Lawv tuaj yeem hloov cov cua sov los ntawm qhov cua sov, xws li CPU lossis GPU, mus rau lub dab dej kub lossis lwm yam khoom cua txias. Lub hauv - dav hlau thermal conductivity ntawm graphite thermal ntawv tuaj yeem siab txog li ob peb puas W / (m·K), uas yog siab dua li ntawm ntau cov khoom siv thermal interface xws li thermal greases thiab pads. Piv txwv li, nyob rau hauv ib lub xov tooj smartphone, ib daim ntawv thermal graphite tuaj yeem kis tau cov cua sov uas tsim los ntawm lub processor sib npaug ntawm lub nraub qaum, tiv thaiv cov pob kub thiab txhim kho tag nrho cov thermal ua haujlwm ntawm lub cuab yeej.
3. Thaum tshav kub kub kis ua haujlwm
Ntxiv nrog rau cov khoom siv hluav taws xob, graphite thermal sheets kuj muaj txiaj ntsig zoo thaum tshav kub kis.

4. Hluav taws xob rwb thaiv tsev muaj nuj nqi
Txawm hais tias graphite yog ib tug zoo conductor ntawm hluav taws xob nyob rau hauv nws cov natural form, tshwj xeeb tshaj yog kho graphite thermal nplooj ntawv yuav muaj zoo heev hluav taws xob rwb thaiv tsev zog. Qhov no yog qhov tseem ceeb hauv cov khoom siv hluav taws xob uas yuav tsum tau muaj hluav taws xob cais tawm. Piv txwv li, nyob rau hauv ib tug siab - voltage fais fab mov los yog ib tug Circuit Court board, graphite thermal daim ntawv yuav siv tau los hloov tshav kub yam tsis ua rau hluav taws xob luv luv - circuits.
Cov cuab yeej hluav taws xob rwb thaiv tsev ntawm graphite thermal ntawv yog ua tiav los ntawm kev kho saum npoo thiab ntxiv cov txheej insulating. Cov ntawv kho mob no tuaj yeem tiv taus cov hluav taws xob siab tsis muaj hluav taws xob, ua rau lawv tsim nyog rau ntau yam kev siv hluav taws xob thiab hluav taws xob.
5. Kev vibration thiab suab nrov txo kev ua haujlwm
Graphite thermal ntawv tuaj yeem ua lub luag haujlwm hauv kev txo qis kev co thiab suab nrov hauv qee qhov kev siv. Thaum lub cuab yeej ua haujlwm, cov tshuab kev co tuaj yeem tsim tawm, uas yuav ua rau lub suab nrov thiab cuam tshuam rau kev ruaj ntseg ntawm lub cuab yeej. Qhov yooj thiab damping zog ntawm graphite thermal ntawv tuaj yeem nqus thiab dissipate lub zog ntawm kev co.
Hauv ib qho nyuaj - disk drive, piv txwv li, daim ntawv graphite thermal tuaj yeem siv los txo qhov kev vibration uas tsim los ntawm spinning disk. Qhov no tsis tsuas yog pab tiv thaiv cov khoom sab hauv ntawm lub zog - disk drive tab sis kuj txo cov suab nrov thaum ua haujlwm, muab qhov chaw ua haujlwm ntsiag to.
