Yam khoom zoo li cas rau Cov Hluav Taws Xob Tshav Kub Teeb Ntawm Cov Teeb Liab?
Kub txheej txheem ntawm LED teeb yog ib qho tseem ceeb heev. Zoo li tag nrho cov tshuab hluav taws xob, LED yuav tsim hluav taws xob thiab kub sawv hauv kev siv lossis khiav lag luam. Yog tias cov tshav kub kub tsis muaj kev tu ncua, nws yuav ua rau cov hlawv roj kub vim qhov kub siab. Ces dab tsi zoo ntawm cov khoom siv rau qhov kub dissipation ntawm LED teeb? Nov yog ib qho kev ntsuam xyuas rau koj.
Muaj ntau hom xov tooj hluav taws xob rau cov teeb roj teeb. Los ntawm kev ntsuas, cov thermal conductivity ntawm co yog raws li nram no:
Silver 429, tooj liab 401, kub 317, txhuas 237, hlau 80, hlau 67, lead 34.8
Sib piv nrog cov ntaub ntawv saum toj no, qhov khoom noj khoom haus zoo tshaj plaws yog nyiaj, tab sis xav tias nws cov nqi, nws yog kwv yees tias ob peb lub bosses yuav ua qhov tsis muaj tswv yim xaiv nyiaj raws li cov khoom. Ntshiab dawb kuj siv kuj me ntsis hauv khw.
Tam sim no, yam khoom siv yog dab tsi siv rau cov roj teeb thiab cov tshuab hluav taws xob hauv khw?
Aluminium profiles feem ntau yog siv, uas yog pheej yig hauv cov ntaub ntawv thiab qis rau hauv cov nqi qhib. Lawv muaj cov khoom muag, txawv txav hauv txav thiab nplua hauv cov xov hlau.
Lub teeb uas zoo siv zoo siv tooj hlau thiab txhuas. Sib koom ua ke nrog tooj liab-txhuas ua ke yog ua kom muaj tooj thiab txhuas zoo nrog lub tshuab ua ke, kom tooj tau hloov cua kub mus rau aluminium sai sai, thiab tom qab ntawd ua kom cua sov ntawm cheeb tsam loj ntawm txhuas. Qhov no tsis tsuas yog tsub kom cov thermal conductivity ntawm txhuas, tab sis tseem ua rau cov cua sov dissipation ntawm tooj yog inferior rau cov aluminium, thiaj li mus cuag cov nyhuv kub ceev hloov thiab sai cua dissipation. Qhov nruab nrab ntawm cov hluav taws xob kub nruab nrab yog peb zaug dua.
Yog hais tias txhua tus paub txog lub computer sib dhos, lub tshav kub ntawm cov teeb taws ntawm no yog zoo ib yam li ntawm lub computer cpu; ntau dua qhov kev ua tau zoo ntawm lub computer cpu, ntau dua qhov uas yuav tsum tau rau cua sov dissipation, tib yam muaj tseeb ntawm teeb lub teeb, thiab lub zog loj zog, qhov ntau dua cov khoom siv rau cov cua sov dissipation; lub cua sov dissipation kuj txiav txim siab seb lub neej ntawm lub teeb muaj peev xwm yeej tuaj txog 50,000 xuab moos.
Yam khoom siv yuav tsum tau them sai sai rau lub tshuab hluav taws xob ntawm cov roj teeb?
Thaum nriav khoom qij qis, tshav kub kub kuj pom tias qhov zoo. Thaum nriav hauv lub khw, taws teeb rau 20 feeb thiab npuav nrog koj txhais tes. Yog hais tias qhov kub siab tshaj 60-70 degrees, nws cov khoom siv hluav taws xob yuav tsum yog muaj teeb meem, tsis txhob xaiv cov khoom zoo li no.
