Hauv cov ntsiab lus ntawm cov khoom siv hluav taws xob niaj hnub ua kom yuag, thiab muaj kev sib koom ua ke, kev sib tw ntawm tshav kub dissipation thiab tshuab txhim kho tau nce zuj zus. Raws li kev ua haujlwm tshiab ua kom zoo nkauj nplaum, thermal ua hauj lwm xev ua ke thiab tsev kawm ntawv conduction thiab tsev neeg ua haujlwm nrog kev daws teeb meem yooj yim thiab muaj txiaj ntsig. Nws tsis yog tsuas yog daim kab xev, tab sis kuj yog ib qho ntawm indispensable thermal interface (sijhawm) hauv precision hauv tshuab txias.
Thermal ua cov kab xev yog daim ntaub nplaum yog daim kab xev {{0} Cov khoom siv sib xyaw ua los ntawm txheej nplaum nrog ob qho khoom siv hluav taws xob ntawm ib substrate.
Cov nqi tseem ceeb:
DUAL lub luag haujlwm nyob rau hauv ib qho: ib txhij ua tiav thermal conduction (sau cov scaps, hloov cov screats), hloov cov screats), hloov cov screat, txo cov khoom siv, thiab txo cov nqi sib dhos.
Hluav taws xob rwb thaiv tsev: feem ntau thermal condes tapes yog cov insulators zoo heev los tiv thaiv cov kab ncig ntawm cov voj voog.
Poob siab nqus thiab buffering: tus nplaum nplaum muaj qee yam elasticity muaj qee yam elasticity thiab tuaj yeem nqus cov kev co thiab kev ntxhov siab.
Cov kev faib tawm siab: Muab cov kev sib koom ua ke ntawm txoj kev sib tiv tauj ntawm tag nrho cov chaw sib cuag tau ua rau kub ua kom sov.
Hnyeeb - dawb / qis voc: feem ntau ib puag ncig phooj ywg.
Ua haujlwm ua haujlwm:
Kev Ua Haujlwm thiab Kho: Cov nplaum nplaum ua kom sib raug zoo rau ob qho chaw sib chwv, khov kho lub tshuab cua kub (inductor kauj) mus rau lub tshuab cua sov (lub tsev sov, hlau nkhaus) lossis PCB.
Rauv kub canuction: lub siab thermal conderivity ntsaws, tusyees dispersed hauv cov nplaum, ua ib txoj kev thermal. Tshav kub yog ua tau zoo los ntawm cov cua sov los ntawm cov npoo cua sov dissipation tivthaiv los ntawm cov thermal conductive muab tub lim network thiab substrate, thiab tom qab ntawd dissipated. Daim kab xev nws tus kheej puv cov ntawv me me ntawm kev tiv tauj saum npoo, tsis suav nrog huab cua, thiab cuam tshuam tiv thaiv thermal tiv thaiv.
MIT thov cov xwm txheej ntawm thermal ua cov kab xev
Cov Neeg Siv Khoom Hluav Taws Xob:
Cov smartphones / ntsiav tshuaj: Tsev kho mob: Kev sib koom ua ke thiab kub dissipation ntawm roj teeb thiab nruab nrab thav ntawv / tom qab npog; Tsau cua sov diss ... cov koob yees duab, cov laug cam me me thiab tsev; Tsau thiab kub -}}} dissipating ntaub npog.
Laptops: Tsevneeg sib khi thiab kub dissipation ntawm cov chips me me, inductors, cov neeg siv hluav taws xob, thiab cov vaj tsev lossis nkhaus; kiv cua txhim kho; ib qho kev txhim kho ntawm qee cov cua sov.
TV / saib xyuas kev ua TV thiab kub conduction ntawm LED lub teeb lub teeb thiab rov qab Panels / tshav kub disps; Hauv zos qis qis - Fais Fab Lub Cev Hluav Taws Kub Dissipation Fixation.
LED teeb pom:
Tsevneeg thiab kub conduction ntawm LED Lub Teeb Strips (xws li lub teeb tej lub teeb, hloov cua sov) thiab cov kua mis hloov tshiab los yog clips).
Ntu kev txhim kho thiab thermal interface ntawm LED cov qauv (xws li COB) thiab kub dissipation substrates.
Automotive Electronics:
Tsevneeg thiab cua sov dissipation ntawm tsheb qhia tawm, Central tswj screen modules, thiab vaj tse / nkhaus.
Kev txhim kho thiab kub dissipation ntawm sensors thiab tswj cov kev ua haujlwm (yuav tsum tau tiv taus ntau qhov kub thiab laus).
Kev kho thiab kub dissipation ntawm cov haiv pov thawj thiab qis - fais fab cuab yeej siv roj teeb tshuab (BMS).
Khoom Sib Txuas Khoom:
Tsevneeg thiab cua sov dissipation ntawm me me modules, tej daim av, thiab cov vaj tsev lossis lub tshuab cua sov sab hauv cov routers thiab pob taws.
Kev txhim kho thiab kev tswj kev tswj thermal ntawm Cheebtsam hauv Optical modules.
Muaj Khoom Siv Hluav Taws Xob:
Tsevneeg thiab cua sov dissipation ntawm me me - Lub raj muaj zog, thiab cov vaj tse ntawm kev lag luam moture.
Ntu kev txhim kho thiab tshav kub txuas ntawm cov khoom sib xyaw sab hauv lub zog.
Lwm tus:
Tsevneeg thiab cua sov dissipation ntawm cua kub cov khoom siv (xws li cov khoom siv tiv thaiv cua sov (xws li cov khoom siv hluav taws xob thiab hloov pauv) uas xav kom muaj rwb thaiv tsev rau qhov chaw mounting.
Hloov cov screws me me lossis buckles kom ua tiav cov seamless thiab ua kom ceev ceev.
Thermal Daim Kab Xev, nrog nws cov cim kev sib xyaw ua ke ntawm thermal conductivity + deling, tau pom muaj zog siv tau tus nqi xws li cov khoom siv hluav taws xob, teeb pom kev zoo, thiab tsheb. Nws muab cov txheej txheem tsim qauv, ua kom ua cov txheej txheem sib dhos, thiab ua kom zoo rau cov teeb meem kub dissipation thiab txhim kho cov hluav taws xob me me thiab nruab nrab hauv nruab nrab. Qhov tseeb xaiv ntawm daim kab xev thermal tsis tuaj yeem txhim kho cov cua sov dissipation efficiency thiab kev ntseeg tau ntawm cov khoom, miniaturization, thiab tus nqi tsim kho ntawm cov khoom.
