Thermal ntaub yog cov tseem ceeb tiv thaiv ntawm cov khoom siv hluav taws xob uas xav tau thermal dissipation. Cov ntaub qhwv no feem ntau ua haujlwm tshem tawm thaum tshav kub kub los ntawm kev sib txawv ntawm cov hluav taws xob hluav taws xob thiab hloov mus rau ib puag ncig cua sov lossis ib puag ncig hluav taws xob.
Hauv tsab xov xwm no, peb yuav coj koj ntawm cov thermal ncoo, lawv cov kev paub kev lag luam, thiab yuav ua li cas lawv ua haujlwm. Peb tseem yuav tshawb nrhiav sib txawv ntawm cov thermal ncoo, lawv cov kev zoo, thiab tsis zoo, thiab qhov tseeb uas koj yuav tsum xav txog ib qho rau koj daim ntawv thov tshwj xeeb.
Thermal ntaub yog tiaj, hloov tau, thiab cov khoom me me ntawm cov khoom ua los ntawm silicone, lossis thermal adhesive. Lawv muaj cov khoom thermal zoo heev uas muaj zog, uas ua rau lawv hloov cua sov kom sov los ntawm cov khoom txias kom txias lossis cov chaw ib puag ncig.
Thermal ntaub yog qhov tseem ceeb hauv cov ntawv thov hluav taws xob xws li khoos phis tawj, cov khoom siv sib txuas, thiab lwm yam khoom siv uas tsim kom muaj cua sov ntau. Tsis muaj thermal ntaub, cov khoom siv hluav taws xob yuav raug kev puas tsuaj rau kev puas tsuaj los ntawm overheating, uas tuaj yeem ua rau raug nqi kho lossis hloov.
Muaj ntau hom ntawm thermal pads muaj nyob hauv kev ua lag luam, uas txawv nyob rau hauv cov nqe lus ntawm lawv muaj pes tsawg leeg, tuab, thiab thermal conductivity. Nov yog qee qhov ntawm lawv:
1. Silicone {- bas based thermal bads- Cov pads yog tsim los ntawm silicone elastomer uas yog qhov ntsuas cua sov. Lawv hloov tau yooj yim, yooj yim thov, thiab zoo tagnrho rau sau gaps ntawm lub dab dej sov, lub zog modules, thiab lwm yam hluav taws xob.
2. fiberglass - bas based thermal based- Cov ntaub fiberglass cov khoom siv nrog ib qho kev coj ua silicone txheej. Lawv yog cov muaj zog heev thiab nthuav tawm cov khoom siv hluav taws xob zoo heev, ua rau lawv haum rau qhov siab- qhov kev siv kub.
3. Cov nplaum {- bas based thermal tov uas tso cai rau lawv lo ruaj nrees rau cov hluav taws xob thiab lub dab dej kub. Lawv yooj yim rau nruab, muab kev ua tau zoo heev thermal, thiab tawm tsis muaj qhov seem ntawm kev tshem tawm.
Thaum xaiv lub ncoo thermal rau koj daim ntawv thov, muaj ntau yam uas koj xav tau xav txog. Nov yog qee qhov ntawm lawv:
1. Thermal conductivity - Qhov no yog lub peev xwm ntawm cov thermal pad hloov kom sov tawm ntawm cov hluav taws xob hluav taws xob. Ib lub thermal ncoo nrog siab thermal conductivity yuav nqa kom sov sai dua ib qho uas muaj thermal conductivity.
2. Thickness - Qhov tuab ntawm lub tshuab thermness cuam tshuam qhov ntau ntawm cov cua sov -} ge} tsim tawm tivthaiv. Ib lub ncoo tuab yuav siv tau ntau dua, yog li nce nws lub peev xwm los hloov cua sov.
3. Nto ua tiav - Qhov saum npoo ua tiav ntawm daim ntaub qhwv hluav taws xob tuaj yeem cuam tshuam nws qhov kev ua haujlwm thermal. Qhov chaw ntxhib yuav txo tus nqi ntawm kev sib cuag ntawm ncoo thiab hluav taws xob sib xyaw, ua rau hauv qhov hloov cua txias.
Hauv kev xaus,Thermal padsyog ib qho tseem ceeb ntawm cov khoom siv hluav taws xob uas xav tau thermal dissipation. Lawv ua ib lub luag haujlwm tseem ceeb hauv kev tiv thaiv cov hluav taws xob hluav taws xob rhiab los ntawm kev kub ntxhov, uas tuaj yeem ua rau puas tsuaj. Thaum xaiv lub ncoo thermal, nws yog qhov tseem ceeb heev los txiav txim siab yam xws li thermal conductivity, tuab, thiab nto kom ntseeg tau tias kev ua tau zoo tshaj plaws. Peb cia siab tias tsab xov xwm no tau muab rau koj muaj txiaj ntsig zoo rau hauv lub ntiaj teb ntawm thermal ntaub thiab lawv qhov tseem ceeb hauv kev lag luam hluav taws xob.
