Yuav ua li cas LED teeb ua kom sov dissipation?

Thaum tshav kub kub dissipation daws teeb pom kev zoo ntawm LED teeb: los daws qhov kub dissipation ntawm LED teeb lub teeb, feem ntau yog los ntawm ob yam, ua ntej thiab tom qab ntim, tuaj yeem nkag siab tias LED nti kub dissipation thiab LED teeb lub teeb kub dissipation.

LED nti hluav taws xob dissipation feem ntau yog cuam tshuam nrog kev xaiv ntawm substrate thiab Circuit Court thiab txheej txheem, ib qho LED yuav ua rau hauv cov teeb, thiab cov cua sov uas tsim los ntawm LED nti yog ib txwm dispersed rau hauv huab cua los ntawm lub plhaub ntawm lub teeb. Vim tias lub peev xwm kub ntawm LED nti yog me me, qhov sib xyaw ntawm cov cua sov me ntsis yuav ua rau qhov sib txuas ntawm cov nti ntawm qhov kub thiab txias, thiab yog tias nws ua haujlwm ntawm qhov kub siab rau lub sijhawm ntev, nws lub neej yuav luv luv. Txawm li cas los xij, rau qhov cua sov no tuaj yeem coj tawm ntawm cov nti mus rau sab nraud huab cua, muaj ntau txoj hauv kev mus. Tshwj xeeb, cov cua sov tsim los ntawm LED nti, los ntawm nws cov hlau txias thaiv, thawj zaug dhau los ntawm cov solder mus rau PCB ntawm txhuas substrate, thiab tom qab ntawd los ntawm cov kua nplaum thermal mus rau aluminium radiator. Yog li ntawd, lub tshav kub dissipation ntawm LED tsev so engineering teeb yeej muaj ob qhov chaw: tshav kub conduction thiab tshav kub dissipation. Lub tshav kub dissipation ntawm LED teeb lub plhaub tseem yuav muaj kev xaiv sib txawv raws li lub zog loj thiab qhov chaw siv.

Feem ntau yog cov hauv qab no ntawm cov cua kub dissipation:

Aluminium fins: Qhov no yog txoj hauv kev zoo tshaj plaws rau dissipate tshav kub, siv aluminium fins ua ib feem ntawm lub plhaub kom ua rau thaj chaw tshav kub.

Thermal conductive yas plhaub: Thaum lub plhaub yas txhaj tshuaj, cov khoom siv thermal conductive tau muab ntim rau kom muaj peev xwm thermal conductivity thiab kub dissipation peev ntawm lub plhaub yas. Aerohydrodynamic tshav kub dissipation: Aerohydrodynamic siv cov duab ntawm lub teeb plhaub los tsim cov cua convective, uas yog tus nqi qis tshaj plaws los txhim kho cov cua sov.

Ntxuam lub teeb plhaub nrog lub neej ntev thiab cov kiv cua kom muaj zog kom sov dissipation: tus nqi qis, cov nyhuv zoo. Txawm li cas los xij, txhawm rau hloov tus kiv cua yog teeb meem ntau dua, thiab nws tsis haum rau sab nraum zoov, qhov kev tsim no kuj tsis tshua muaj.

Thaum tshav kub kub hloov tube kub dissipation tshuab: Thaum tshav kub kub hloov tube siv cov cua sov hloov tube tshuab los ncaj qha tshav kub los ntawm LED nti mus rau lub plhaub kub dissipation fin. Nyob rau hauv cov teeb loj, xws li txoj kev teeb, qhov no yog ib qho qauv tsim.

Deg hluav taws xob tshav kub dissipation kev kho mob Qhov saum npoo ntawm lub teeb plhaub rau hluav taws xob kub dissipation kev kho mob: yooj yim yog siv cov hluav taws xob hluav taws xob hluav taws xob dissipation txheej, uas tuaj yeem tshem tawm cov cua sov tawm ntawm lub plhaub ntawm lub teeb hauv txoj kev tawg.
