Qhov teeb meem ntawm tshav kub dissipation ntawm lub pob tshab LED npo yog tus yuam sij rau kev ua haujlwm thiab lub neej ntawm LED npo. Cov khoom siv sab hauv ntawm lub vijtsam pob tshab yog cov khoom siv hluav taws xob uas tsim kom muaj cua sov tshaj plaws, xws li LED teeb hlaws, tsav ICs, thiab cov khoom siv hluav taws xob. Nyob rau hauv cov huab cua kub tshwj xeeb, yog hais tias lub tshav kub dissipation sib txawv tsis raws sij hawm, lub screen lub cev yuav tshwm xim cam khwb cia. Yog tias qhov kub thiab txias dhau lawm, cov cua sov tsis tuaj yeem tawg, uas yuav ua rau cov khoom siv sab hauv ntawm lub vijtsam pob tshab thiab ua rau lub vijtsam ua haujlwm tsis zoo.
coj pob tshab npo
Los ntawm kev siv lub cev cua sov dissipation, huab cua convection tshav kub dissipation, cua txias tub yees thaum tshav kub kub dissipation, duct hom cua sov dissipation thiab kub conduction cov ntaub ntawv nyob rau hauv cov khoom tsim, ntau lawm ua thiab engineering tsim, lub tshav kub dissipation teeb meem ntawm pob tshab LED cov ntxaij vab tshaus yog daws. Nyob rau hauv cov khoom tsim, lub teeb bar hom qauv tsim, muaj qhov sib txawv ntawm lub teeb tuav, cov cua sov ntawm lub teeb hlaws tuaj yeem tawm sai sai, thiab cov cua kub dissipation ua tau zoo.
Xaiv cov khoom siv hluav taws xob zoo thiab ruaj khov dua. Piv txwv li, rau cov khoom siv hauv lub thawv, Winbond xaiv cov aluminium zoo nrog cov cua kub zoo thiab oxidation tsis kam, thiab optimizes cov qauv ntawm PCB board hluav taws xob cov khoom kom yooj yim thiab rationally npaj. Ntxiv mus, ntau txheej txheej tsim tsim nyob rau hauv lub thawv tsim ib tug tag nrho pob tshab convective tshav kub dissipation qauv, uas ua rau tag nrho cov kev siv ntawm tej yam ntuj tso cua rau convection tshav kub dissipation, uas tsis tsuas yog yuav siv sij hawm mus rau hauv tus account thaum tshav kub kub dissipation thiab sealing, tab sis kuj txhim kho kev ntseeg tau thiab kev pab lub neej. . Tsis tas li ntawd, hais txog cov khoom siv kho vajtse, xws li kev siv TG170 rau lub rooj tsavxwm PCB, uas tuaj yeem tiv taus qhov kub thiab txias ntawm 170 degree, nws kuj tseem tiv thaiv qhov tsis zoo ntawm cov cua sov thiab ua kom lub cev ua haujlwm ntawm lub vijtsam.
Nyob rau hauv ib txwm muaj, qhov nruab nrab lub zog noj ntawm cov pa LED npo yog 350W / square, thiab lub zog siab tshaj plaws yog kwv yees li 900W / square; Thaum qhov nruab nrab lub zog noj ntawm pob tshab LED zaub yog li 250W / square, qhov siab tshaj plaws siv hluav taws xob yog li 700W / square; Qhov piv ntawm pob tshab LED zaub nyob rau hauv chav tsev square Pas duab cov ntxaij vab tshaus tuaj yeem txuag hluav taws xob los ntawm 100W txog 200W, uas tuaj yeem txuag tau ntau cov nqi hluav taws xob tom qab siv mus ntev. Kev siv hluav taws xob tsawg, lub zog hluav taws xob tsawg, lub vijtsam lub cev yuav tsis siab dhau, thiab lub vijtsam zaub tuaj yeem ua haujlwm ib txwm nyob hauv ib puag ncig kub.
Cov zaub hom yog qhov sib txawv loj ntawm lub pob tshab LED npo thiab cov lus pom zoo. Thaum cov pa LED zaub screen ua haujlwm, qhov pib tag nrho cov ntsiab lus yog ci thiab cua sov; Thaum lub pob tshab LED npo ua haujlwm, tsuas yog qhov chaw tso tawm yuav ci thiab cua sov, thiab lwm qhov chaw yuav tsis tawm lub teeb. Qhov ntsuas kub ntawm qhov screen yog qis dua li ntawm cov pa screen.
Hauv cov ntsiab lus, cov qauv tsim tsim nyog thiab lub thawv qauv ua kom ntseeg tau tias cov pob tshab LED zaub muaj qhov ua tau zoo ntawm cov cua sov dissipation thiab kev siv hluav taws xob tsawg. Nws yog lub cim tshiab ntawm cov khoom lag luam ntsuab, thiab nws cov permeability siab, ntsuab txuag hluav taws xob thiab lwm yam zoo heev uas tsis yog nws tsuas yog ua kom zoo nkauj ntawm lub tsev, thiab tseem txhim kho cov duab thiab kev lag luam muaj txiaj ntsig hauv thaj chaw ntawm architectural iav kab hlau rhuav phab ntsa.
