5G telecom ntaus ntawv thermal tsim qauv
Piv nrog 4G, 5G nce los ntawm tsawg kawg yog 9 ~ 10 npaug. Nyob rau hauv lub era ntawm 5G network, tsis muaj teeb meem dab tsi 5G kev daws teeb meem yog inseparable los ntawm 5G kev sib txuas lus li, thiab 5G muaj ntau dua thiab siab dua cov kev cai rau optical li, xws li me me ntim, siab integration, siab npaum thiab tsawg zog noj. Cov khoom siv feem ntau siv rau 5G rau pem hauv ntej, nruab nrab thiab rov qab kis tau tus mob yog 25G, 50G, 100G, 200G thiab 400G optical li, Ntawm lawv, 25G thiab 100G optical li yog cov khoom siv 5G kev sib txuas lus dav tshaj plaws.
Nrog rau qhov siab dua thiab ntim me me, qhov no yog qhov kev zam tsis tau ntawm txoj kev loj hlob ntawm cov khoom siv kho qhov muag. Nyob rau tib lub sijhawm, nws kuj coj cov kev xav tau siab dua rau kev tswj hwm thermal sab hauv ntawm cov khoom siv kho qhov muag. Yuav ua li cas kom sai thiab zoo cua sov dissipation yog ib qho teeb meem uas yuav tsum tau ua tiag tiag.
Vim li cas thiaj xav tau thermal tsim:
Raws li peb txhua tus paub, thaum peb photoelectric nti ua haujlwm, nws yuav tsis hloov 100 feem pua ntawm cov kev txhaj tshuaj tam sim no rau hauv cov zis optoelectronics, thiab ib feem ntawm nws yuav raug siv los ua lub zog poob hauv daim ntawv ntawm tshav kub. Yog tias cov cua kub ntau ntxiv mus ntxiv thiab tsis tuaj yeem tshem tawm hauv lub sijhawm, nws yuav muaj ntau yam tsis zoo rau kev ua haujlwm ntawm cov khoom. Feem ntau hais lus, nrog rau qhov nce ntawm qhov kub thiab txias, qhov kev tiv thaiv tus nqi txo thiab kev pab cuam lub neej ntawm cov khoom siv yuav raug txo, kev ua haujlwm tsis zoo, cov ntaub ntawv laus thiab cov khoom puas; Tsis tas li ntawd, qhov kub thiab txias kuj tseem yuav ua rau muaj kev ntxhov siab thiab deformation ntawm cov khoom, txo qhov kev ntseeg siab thiab ua haujlwm tsis zoo ntawm cov cuab yeej.
Muaj peb txoj hauv kev ntawm kev hloov hluav taws xob: kev siv hluav taws xob, hluav taws xob convection thiab hluav taws xob hluav taws xob.
Thaum tshav kub kub conduction:
Lub nti dissipates cua sov los ntawm lub dab dej kub hauv qab, thiab cov khoom siv kho qhov muag tiv tauj lub plhaub rau cov cua sov dissipation los ntawm tshav kub dissipation silicone roj, tag nrho cov uas yog los ntawm tshav kub conduction.
Thaum tshav kub kub convection:
Ntuj convection tsuas yog siv lub zog buoyancy tshwm sim los ntawm qhov sib txawv ntawm qhov kub thiab txias ntawm cov kua dej sib txawv los pauv cov cua sov. Nws yog ib txoj kev ua kom sov dissipation, uas yog haum rau ib puag ncig uas tsis muaj calorific nqi. Hauv cov xov tooj ntawm tes, kho qhov muag modules thiab lwm yam khoom siv davhlau ya nyob twg, cov khoom siv hluav taws xob hloov hluav taws xob hloov pauv yog siv.
Forced convection heat transfer yog ib txoj hauv kev ua kom cov cua sov ua kom zoo los ntawm kev ua kom cov dej kub hloov pauv los ntawm cov khoom siv hluav taws xob sab nraud xws li cov twj tso kua mis thiab cov kiv cua, uas yuav tsum muaj peev nyiaj txiag ntxiv. Nws yog qhov tsim nyog rau qhov xwm txheej ntawm tus nqi calorific loj thiab qhov chaw tsis zoo ntawm cov cua sov dissipation; Cov kiv cua txias feem ntau yog siv rau cov khoom siv kho qhov muag ua haujlwm hauv cov khoom siv lossis cov keyboards, uas yog qhov raug yuam kom hloov cov cua sov.
Thaum tshav kub kub hluav taws xob:
Cov txheej txheem ntawm kev xa hluav taws xob los ntawm electromagnetic tsis. Thermal hluav taws xob yog cov txheej txheem ntawm emitting electromagnetic vuag thaum qhov kub ntawm ib yam khoom yog siab tshaj li xoom kiag li. Kev hloov cov cua sov ntawm ob yam khoom los ntawm thermal tawg yog hu ua hluav taws xob hloov hluav taws xob. Cov txheej txheem cua sov no yog siv tsawg dua hauv kev tsim thermal vim nws tsis zoo.
