Thermal ntaub yog pre - tsim duab ntawm cov khoom siv uas ib txwm muab tso rau ntawm cov khoom seem ntawm cov tshuab hluav taws. Lawv pab coj ua kom sov ntawm ib qho kev sib xyaw thiab rau hauv cov cua sov. Qhov no tso cai rau cov khoom sib xyaw ua haujlwm kom ua tau zoo dua thiab txo cov nqi hluav taws xob. Siv thermal ntaub yog ib txoj kev yooj yim los tiv thaiv koj cov cuab yeej los ntawm kev kub siab.
Thermal ncoo yog feem ntau siv nyob rau hauv laptops thiab desktop computers kom ntseeg tau kev ua tau zoo. Feem ntau, lawv tau ua los ntawm silicon lossis lwm cov khoom haum uas tsim nyog.
Thermal ncoo yog qhov yooj yim rau siv thiab nruab dua li thermal muab tshuaj txhuam. Vim tias lawv twb txiav rau qhov loj me, tsis tas yuav muaj kev ntsuas ntau, thiab koj tsis tas yuav txhawj txog kev ntxuav cov tshuaj txhuam. Koj kuj tsis tas yuav txhawj txog cov tshuaj txhuam muab rau ntawm cov cua sov lossis cua sov. Thermal muab tshuaj thermal tseem yog qhov kev xaiv zoo rau cov qauv zoo nkauj lossis cov qauv sib txawv.
Txawm hais tias hom ntawm thermal muab tshuaj txhuam koj xaiv, qhov tseem ceeb tshaj plaws yog tias nws dhau Nasa cov qauv outgassing. Cov pastes thermal yuav tsum qis qis qis los tiv thaiv cov hws hws ntawm cov khoom siv kho qhov muag. Cov thermal muab tshuaj txhuam yuav tsum tau siv tusyees thiab kom tsis txhob muaj cua khoob thiab messes. Ib txheej nyias nyias ntawm thermal muab tshuaj txhuam yog ntau dua ua tau zoo dua li txheej tuab.
Thermal ntaub yog lwm qhov kev xaiv zoo rau cov khoom txias. Lawv siab thermal conductivity tseem ceeb tuaj yeem pab ua kom lub CPU txias yam tsis muaj kev ua tau zoo. Thermal ntaub yog ua los ntawm cov khoom uas tsis yog- pa, tsis yog} corrosive, thiab yooj yim thov. Thermal ntaub ntawv tseem tau tshaj ntau ntau ntawm SMD Cheebtsam.
Thermal ntaub yog muaj nyob rau hauv ntau thicknesses. Cov no feem ntau yog 1.5mm, 2 hli, thiab 3 hli hauv tuab. Lub thermal ncoo muaj 3.0 w / m - k thermal conductivity. Cov ntaub ntawv thermal no yog qhov kev xaiv zoo rau cov pib tshiab. Lawv kuj yooj yim dua los thov dua lwm cov khoom siv thermal interface.
Thermal muab tshuaj txhuam yog cov khoom siv ua kua uas tau thov rau saum npoo ntawm ib qho. Nws puv cov cua txias nruab nrab ntawm cov kub sib tshooj thiab nws cov cua sov. Nws nce thaj tsam thaj tsam ntawm cov khoom sib xyaw, uas txhim kho cov cua sov hloov thiab kev txuag hluav taws xob. Thermal muab tshuaj thermal feem ntau siv nyob rau hauv kev lag luam automotive. Qhov no muab tshuaj txhuam muaj cov txiaj ntsig ntxiv ntawm kev muaj peev xwm tuav tau ntev - siv siv.
Thermal ntaub qhwv tau tuaj yeem yog kev cai - tsim kom haum ntau yam kev siv. Lawv tuaj yeem ua tau los ntawm ntau cov ntaub ntawv suav nrog silicone -} silicone. Lawv kuj tseem muaj nyob hauv kev cai tuag - txiav qhov chaw. Lawv kuj tuaj yeem tsim tawm rau cov thickness tshwj xeeb. Ib qho kev cai tuag - nplej ib qho yuav xav tau cov nqi tuam, uas sib txawv nrog qhov nyuaj ntawm feem.
Thermal padsPuas yog cov tshuaj zoo rau txias siab - fais fab siciconductor pab kiag li lawm. Lawv feem ntau siv nyob rau hauv high-} kawg cov kev daws teeb meem thiab yuav tsum muaj qhov tseeb tuab thiab cov duab kom ntseeg tau tias kub hloov pauv.
Thermal ntaub ntawv pab hloov kom sov ntawm ib lub PCB. Cov pads no feem ntau pom nyob rau hauv qab ntawm watcheinks txhawm rau txhim kho kev ua kom sov. Lawv tseem hu ua cov ntaub qhwv cov ntaub qhwv. Lawv kuj tau siv los pab solder los ntawm - qhov ua rau pab tswj kom muaj cua sov.
