Kev tswj hwm kub tau dhau los ua ib qho tseem ceeb ntawm kev ruaj khov muaj kev ruaj khov thiab lub neej ntawm cov khoom hluav taws xob uas lawv tau txais me dua thiab muaj zog dua. Vim tias nws cov txiaj ntsig tshwj xeeb, qhov kev xaiv cov ntaub nplaum, muaj cov cua sov zoo heev hloov pauv hauv ntau cov haujlwm sib txawv.
Yuav ua li cas Thermally Mark ua haujlwm
Lub sab hauv thermally ua rau folding ntawm cov kab xev thermally yog qhov tseem ceeb rau nws qhov hloov cua sov. Feem ntau, cov ntsaws no yog tsim los ntawm cov ntaub ntawv zoo li graphene, carbon fiber, thiab hlau oxides uas muaj kub kub conductivity. Cov fillers no yog uniformly faib thoob plaws lub nplaum matrix thoob plaws hauv daim kab xev-}}}}} kev ua kom sov sov.
Cov khoom siv hluav taws xob kub tau tsim los ntawm cov hluav taws xob hluav taws xob tau thauj mus rau sab hauv thermally bitters los ntawm qhov chaw pleev cov kab xev uas tau nkag mus rau cov kab xev. Lub tshav kub kub tuaj yeem nrawm diffuse raws cov kev no los ntawm high- qhov chaw kub kom muaj kev sib tshuam ntawm cov filters. Nws thiaj li, cov cua sov yuav zom rau ntawm ib puag ncig ib puag ncig los ntawm tshav kub dissipation Cheebtsam, txias lub tshuab hluav taws xob. Ntxiv nrog rau kev ua kom ruaj khov ua cov npias, cov nplaum nplaum ntawm cov kab xev thiab cua sov, txo kev sib cuag hluav taws xob thiab kev sib cuag hluav taws xob. Qhov kev tiv tauj no thermal kev tawm tsam ntxiv txhim kho kev hloov kho tshav kub ntxiv thiab txhim kho thermal conductivity.
Cov ntawv thov ntawm Thermally coj cov kab xev
Thermal ua cov kab xev yog siv nyob rau ntau thaj teb thiab yog qhov tseem ceeb rau cov hluav taws xob thiab kev lag luam hluav taws xob. Cov ntu ntawm cov neeg siv khoom lag luam, suav nrog CPU thiab GPU, tsim ntau cov cua sov hauv cov gadget zoo li laptops, ntsiav tshuaj, thiab xov tooj ntawm tes. Cov ntu no tuaj yeem txuas nrog cov kab hlau thiab cua sov siv cov kab xev kub ua kom sov, uas tau lees tias kub thiab lav ua haujlwm.
Raws li lub zog tshiab cov tsheb tau tsim, cov cua sov dissipation uas yuav tsum muaj roj teeb cov tshuab tswj roj teeb thiab cov khoom siv hluav taws xob tau txais ntau yam xav tau. Vim tias nws cov versatility tshwj xeeb thiab kev cia siab, kev siv cov kab xev hluav taws xob tsis txaus ntseeg ntawm cov khoom siv hluav taws xob ua kom muaj kev ua haujlwm nyuaj.
Thaum siv teeb pom kev zoo, kub yog tsim los ntawm cov teeb LED. Qhov kev ua tau ntev thiab luminous efficiency ntawm cov LED yuav cuam tshuam yog tias qhov cua sov no tsis nrawm tso tawm. LED qij 'lifespan tau nce, thiab lawv cov cua sov dissipation efficiency tau nce los ntawm kev sib txuas rau lawv rau cov dej sov uas siv cov kab xev kub.
Cov ntsiab lus tseem ceeb rau kev yuav khoom ntawm cov kab xev
Thawj qhov kev coj mus rau hauv tus account thaum xaiv cov kab xev thermally yog nws cov cua sov. Sib txawv thermal conductivity kev ua tau zoo yog xav tau rau cov ntawv thov sib txawv. Raws li cov khoom siv hluav taws xob cov kev xav tau rau cov khoom siv hluav taws xob thiab kev ploj, koj yuav tsum xaiv cov khoom lag luam nrog txoj cai thermal conductivity. Nyob rau hauv dav dav, thermal conductivity nce li cua kub nce ntxiv.
Thib ob, xav txog lub zog ntawm txoj hlua khi. Lub hauv hluav taws xob thiab cua sov -}}}}}}}}}}}} Cov kab xev khov kho txuas rau qhov ntaub nplaum. Lub haum xoob coj los ntawm kev sib tw sib tw tsis txaus yuav ua rau muaj kev sib cuag thermal tsis kam thiab muaj kev cuam tshuam rau ntawm tshav kub dissipation. Txheeb xyuas qhov sib txuas lus muaj zog thiab sim cov khoom lag luam hauv qhov tseeb- ntiaj teb kev ua haujlwm ua ntej ua kev yuav khoom.
Qhov kub kub kuj yog lwm qhov tseem ceeb me ntsis.Thermally coj cov kab xevYuav tsum tau ua haujlwm txuas ntxiv ua haujlwm nyob rau hauv qhov ntsuas kom haum kom yog tsis tau xoob lossis dhau los ntawm cov khoom siv hluav taws xob yuav raug hloov kom sov thaum siv. Xaiv Thermal daim kab xev uas nws qhov kub tsis kam haum rau qhov ntau ntawm qhov kub uas koj cov khoom siv gadget.
Coj mus rau hauv tus account daim kab xev qhov ntev thiab tuab zoo li. Xaiv cov tuab tuab thiab qhov loj me rau koj cov chaw teeb tsa tau lees tias muaj kev teeb tsa kub tsis muaj kev cuam tshuam vim cov khoom sib txawv muaj qhov chaw muaj txwv.
Kawg tab sis tsis tsawg, xaiv cov chaw tsim khoom siv tau zoo thiab hom yog qhov tseem ceeb. Ruaj khov thiab muaj kev vam khom cov khoom lag luam yog lav los ntawm high- cov txheej txheem tswj hwm zoo thiab cov txheej txheem ntau lawm. Ib qho ntxiv, lawv muaj txhij txhua - Kev muag khoom thiab cov kws pab kev sib txuas lus los pab cov neeg siv daws teeb meem uas yuav tshwm sim thaum siv cov khoom lag luam.
