Thermal tsim ntawm tub rog electronic device
Nrog rau txoj kev loj hlob sai ntawm kev tshawb fawb thiab thev naus laus zis, cov cuab yeej siv hluav taws xob koom nrog hauv kev ua haujlwm ntawm kev tiv thaiv lub teb chaws thiab cov cuab yeej ua tub rog tau dhau los ua ntau dua, kev txiav thiab ntse.
Nyob rau tib lub sijhawm, vim cov kev xav tau ntawm kev siv tub rog rau cov khoom lag luam miniaturization, lub teeb yuag, kev hloov kho thiab kev ntseeg siab, engineers tau ntsib nrog cov kev sib tw hauv cov txheej txheem tsim, xws li millimeter yoj electromagnetic compatibility, cua txias thiab cua sov dissipation nyob rau hauv high tshav kub. flux, sealing hauv ib puag ncig hnyav thiab lwm yam.
Complex ua haujlwm ib puag ncig:
Qhov siab, qhov kub thiab txias, tsis kub, av noo, kub poob siab, hnub ci thermal hluav taws xob, poob siab kev co, dej khov, ntau yam hnyav ib puag ncig (fungi, suab puam, plua plav, soot, thiab lwm yam) txhua tus muaj qhov sib txawv ntawm qhov cuam tshuam rau nws cov thermal tsim.
Kev ua cov ntaub ntawv loj thiab cov nqi calorific siab:
Raws li qhov xwm txheej ntawm kev ua tub rog, cov khoom siv hluav taws xob no tau ua txhua yam los ua cov ntaub ntawv ntau. Nyob rau tib lub sijhawm, lawv xav tau cov ntaub ntawv ua haujlwm sai dua, uas yog qhov sib npaug qis, thiab cov khoom siv hluav taws xob siv hluav taws xob yuav nce siab.
Yog li ntawd, kev tswj xyuas thermal ntawm cov khoom siv hluav taws xob hauv kev lag luam tiv thaiv hauv tebchaws tau ntsib cov teeb meem loj vim yog qhov tsis zoo ntawm ib puag ncig thiab kev siv cov chips sai sai.
Lub teeb yuag thiab kev ntseeg siab nce qhov nyuaj:
Qhov sib dua ntawm qhov hnyav, lub sijhawm ua haujlwm txuas ntxiv ntawm cov khoom siv ntev dua thiab tus nqi qis dua. Cov khoom siv hluav taws xob tuaj yeem siv tsis tu ncua thiab ruaj khov nyob rau hauv ib puag ncig hnyav thermal depands ntawm thermal kev ntseeg tau.
Thermal tsim ntawm tub rog ntaus ntawv:
Txij li thaum siv hluav taws xob siab thiab qhov chaw ua haujlwm tsis zoo ntawm cov khoom siv hluav taws xob ua tub rog, cov chips feem ntau qhia cov cua sov ntau dua. Zoo ib yam li lwm yam khoom siv hluav taws xob, lawv yuav tsum muaj qhov cua txias zoo, uas yuav tsum tau xav txog ntawm cov khoom siv ua haujlwm qhov loj me, qhov hnyav, kev siv hluav taws xob, kev tiv thaiv hluav taws xob thiab lwm yam yuav tsum tau txiav txim siab.
Xws li siv cov khoom siv substrate nrog cov thermal conductivity, VC kub sib npaug phaj, cov yeeb nkab kub, TEC embedded hauv nti tuag, dav hlau cua txias lossis ncaj qha immersion kua txias, cov cua sov tuaj yeem xa mus rau cov kua thiab tom qab ntawd mus rau lub tshav kub exchanger ntawm cov kua txias. qhov system.
Nyob rau yav tom ntej, cov khoom siv hluav taws xob ntau dua nrog cov thermal conductivity ntau dua thiab kev ua haujlwm zoo dua yuav tawm los, yog li lawv tuaj yeem tsis tsuas yog ua tau raws li cov khoom siv hluav taws xob hauv tub rog thiab muab kev lees paub thiab kev tiv thaiv rau kev ua haujlwm ntawm tub rog cov khoom siv hluav taws xob, tab sis kuj tau nthuav dav kev lag luam thermal tswj rau pej xeem cov khoom siv high-end thiab txhawb kev koom ua ke ntawm cov tub rog thiab pej xeem technologies.
