Muaj ntau txoj hauv kev ua kom sov dissipation
Kev ua haujlwm ntawm cov khoom siv hluav taws xob tau dhau los ua qhov muaj zog, thaum kev sib koom ua ke thiab kev sib dhos ceev tau nce tas li, ua rau muaj kev nce ntxiv hauv lawv cov kev siv hluav taws xob thiab kev siv hluav taws xob. Cov khoom siv tsis ua haujlwm los ntawm cov cua sov hauv cov khoom siv hluav taws xob suav nrog feem ntau ntawm tag nrho cov kev ua tsis tiav, thiab kev tswj xyuas thermal yog qhov tseem ceeb hauv cov khoom siv hluav taws xob. Nws yog ib qho tsim nyog los ntxiv dag zog rau kev tswj xyuas thermal ntawm cov khoom siv hluav taws xob hauv qhov no.
Kev ua kom muaj cua sov zoo ntawm cov khoom siv hluav taws xob yog cuam tshuam los ntawm cov hauv paus ntsiab lus ntawm kev hloov hluav taws xob thiab cov tshuab ua kua dej. Lub tshav kub dissipation ntawm cov khoom siv hluav taws xob yog los tswj kev ua haujlwm kub ntawm cov khoom siv hluav taws xob, yog li ua kom lawv cov kub thiab kev nyab xeeb ua haujlwm, feem ntau cuam tshuam nrog cov khoom sib txawv xws li cov cua kub dissipation thiab cov ntaub ntawv. Tam sim no, cov cua kub dissipation ntawm cov khoom siv hluav taws xob feem ntau suav nrog ntuj, yuam, kua, tub yees, kev hloov pauv, kev cais tawm thermal thiab lwm yam.
Cov tshuab cua txias feem ntau yog hais txog txoj hauv kev, txoj hauv kev, thiab cov txheej txheem ntawm kev tsim thermal sab nraud, uas muaj ntau yam xws li cov cua sov dissipation lossis txias txoj kev, cov ntaub ntawv, thiab lwm yam ntsig txog kev hloov hluav taws xob. Raws li cov txheej txheem sib txawv ntawm kev siv hluav taws xob thiab convection, cov khoom siv hluav taws xob tuaj yeem muab faib ua hom nquag thiab tsis muaj zog.
Kev ua kom txias txias yog ib txoj hauv kev ua kom txias txias, uas siv cov thermal conductivity ntawm cov ntaub ntawv (feem ntau yog profiles) kom tshem tawm cov cua sov thiab dissipate rau hauv huab cua. Thaum tsis muaj qhov tshwj xeeb cua ceev yuav tsum tau, lub ntuj convection cua sov dab siv yog tooj liab aluminium phaj, aluminium extrusion, alloy casting kom ua tiav cov khoom txias. Cov txheej txheem cua txias feem ntau yog siv rau hauv cov khoom siv hluav taws xob uas tsis muaj kev tswj xyuas qhov kub thiab txias, cov cuab yeej siv hluav taws xob tsawg thiab cov khoom siv hluav taws xob tsawg tsawg rau cov cuab yeej cua sov.
Forced cua txias txoj kev yog ib txoj hauv kev kom ceev cov huab cua nyob ib ncig ntawm cov khoom siv hluav taws xob thiab tshem tawm cov cua sov los ntawm cov kiv cua thiab lwm yam. Force Cua txias kuj yog ib qho kev siv hluav taws xob sib xyaw ua ke, uas yog qhov yooj yim rau kev tsim khoom, muaj qhov zoo ntawm tus nqi qis, thiab kev teeb tsa yooj yim. Txoj kev no tuaj yeem siv rau hauv cov khoom siv hluav taws xob yog tias qhov chaw loj txaus rau huab cua txaus lossis yog tias qee qhov chaw tso cua sov tau teeb tsa. Nyob rau hauv kev xyaum, tsim nyog nce tag nrho cheeb tsam ntawm tshav kub dissipation thiab tsim ib tug kuj loj convective tshav kub hloov coefficient nyob rau hauv lub tshav kub dissipation nto yog lub ntsiab txoj hauv kev los txhim kho no convective tshav kub hloov chaw.
Daim ntawv thov cov kua txias rau cov khoom siv hluav taws xob yog ib txoj kev ua kom txias raws li cov chips thiab cov chips. Kev ua dej txias tuaj yeem muab faib ua ob txoj hauv kev: cua txias ncaj qha thiab tsis ncaj qha cua txias. Txoj kev ua kua txias tsis ncaj yog hais txog kev siv cov kua ua kua uas tsis tuaj yeem nkag mus rau hauv cov khoom siv hluav taws xob ncaj qha, tab sis hloov pauv cov cua sov ntawm cov khoom siv cua sov los ntawm qhov nruab nrab nruab nrab siv cov cuab yeej pab xws li cov khoom siv ua kua, cov khoom siv thermal conductivity, cov tshuaj tsuag kua. modules, thiab kua substrates.
Txoj kev ncaj qha ua kua txias, tseem hu ua immersion txias txoj kev, yog ncaj qha mus cuag cov kua nrog cov khoom siv hluav taws xob, tshem tawm cov cua sov los ntawm lub coolant, thiab feem ntau siv rau cov khoom siv nrog cov khoom siv hluav taws xob siv hluav taws xob tsawg lossis hauv qhov chaw kub kub.
Los ntawm kev siv semiconductor txias kom dissipate tshav kub los yog txias ib co pa hluav taws xob Cheebtsam, kuj hu ua thermoelectric txias, txoj kev no siv Peltier nyhuv ntawm cov khoom semiconductor nws tus kheej kom tso cai tam sim no los ntawm txawv semiconductor cov ntaub ntawv thiab tsim ib tug thermocouple nyob rau hauv series. Thaum lub sijhawm no, cov cua sov tau nqus thiab tso tawm ntawm ob qho kawg ntawm lub thermocouple kom ua tiav cov nyhuv txias. Nws muaj qhov zoo ntawm cov cuab yeej me me, yooj yim installation, zoo zoo, thiab yooj yim disassembly.
Thermal cais yog hais txog kev siv cov cuab yeej rwb thaiv tsev kom dissipate tshav kub thiab txias hluav taws xob. Nws yog feem ntau muab faib ua ob hom: lub tshuab nqus tsev rwb thaiv tsev thiab tsis nqus tsev vacuum. Hauv kev tswj qhov kub thiab txias ntawm cov khoom siv hluav taws xob, tsis siv lub tshuab nqus tsev rwb thaiv tsev yog siv. Txoj kev sib cais thermal feem ntau cuam tshuam rau qhov kub thiab txias ntawm cov khoom hauv zos, ntxiv dag zog rau kev tswj hwm, thiab tiv thaiv cov cua kub los ntawm cov khoom siv kub kub thiab lwm yam khoom, yog li ua kom muaj kev ntseeg siab ntawm tag nrho cov khoom thiab txuas ntxiv lub neej ntawm cov khoom siv. Hauv kev xyaum, vim tias qhov kub thiab txias cuam tshuam ncaj qha rau kev hloov pauv ntawm cov ntaub ntawv rwb thaiv tsev, feem ntau qhov kub thiab txias, cov ntaub ntawv rwb thaiv tsev ntau dua yuav tsum tau.
Nyob rau hauv txoj kev loj hlob ntawm kev sib xyaw ua ke, qhov ceev thiab kub ceev ntawm cov khoom siv hluav taws xob txuas ntxiv mus ntxiv, thiab lawv cov teeb meem thermal tau maj mam dhau los ua qhov tseem ceeb. Cov txheej txheem ua kom txias zoo tuaj yeem ua kom ntseeg tau qhov ntsuas kev ua haujlwm ntawm cov khoom siv hluav taws xob. Hauv kev siv tswv yim, nws yuav tsum ua tib zoo xav txog qhov tshwj xeeb cua sov lub zog thiab nws tus kheej cov yam ntxwv ntawm cov khoom siv hluav taws xob, thiab tsim nyog siv cov txheej txheem txias sib txawv. Nws yog ib qho tsim nyog yuav tsum xaiv cov txheej txheem kev thov thiab txhais tau tias raws li cov xwm txheej tshwj xeeb ntawm daim ntawv thov, thiab yog li qhia txog kev ua tau zoo ntawm cov khoom siv hluav taws xob.
