Dab tsi yog vim li cas rau lub tshav kub dissipation tsis ua hauj lwm ntawm tawg-pov thawj LED teeb?
Yog vim li cas rau lub tshav kub dissipation tsis ua hauj lwm ntawm tawg-pov thawj LED teeb yog soj ntsuam raws li nram no:
1. Lub thermal tsis kam ntawm LED lub teeb qhov chaw yog qhov loj, thiab qhov kub ntawm lub teeb ci tsis tuaj yeem dissipated. Kev siv cov thermal paste yuav ua rau lub tshav kub dissipation txav tsis tau.
2. Siv aluminium substrate li PCB los txuas lub teeb ci. Vim tias aluminium substrate muaj ntau yam thermal resistances, qhov kub ntawm lub teeb tsis tuaj yeem kis tau. Kev siv cov thermal paste yuav ua rau lub tshav kub dissipation txav tsis tau.
3. Tsis muaj qee qhov chaw rau thermal buffering ntawm lub teeb-emitting nto, uas yuav ua rau lub tshav kub dissipation tsis ua hauj lwm ntawm LED teeb qhov chaw thiab lub teeb thaum ntxov. Qhov saum toj no peb hom yog vim li cas lub ntsiab yog vim li cas rau qhov tsis ua hauj lwm ntawm tshav kub dissipation ntawm LED teeb pom kev zoo khoom nyob rau hauv kev lag luam. Tsis muaj kev daws teeb meem tiav. Qee lub tuam txhab loj siv ceramic substrates rau kev ntim khoom ntawm lub teeb hlaws kom dissipate tshav kub, tab sis lawv tsis tuaj yeem siv dav vim cov nqi siab.
Nov yog yuav ua li cas txhim kho nws:
1. Roughening saum npoo ntawm lub radiator ntawm tawg-pov thawj LED teeb yog ib txoj hauv kev los txhim kho lub peev xwm ntawm tshav kub dissipation.
Lub roughening ntawm qhov chaw txhais tau hais tias tus du nto tsis raug xaiv. Nws tuaj yeem ua tiav los ntawm kev siv lub cev thiab tshuaj. Feem ntau, sandblasting thiab oxidation txoj kev yog siv. Xim kuj yog ib txoj kev tshuaj, uas tuaj yeem ua tiav los ntawm oxidation. Ua kom cov cheeb tsam los txhim kho lub tshav kub dissipation muaj peev xwm ntawm tawg-pov thawj LED teeb.
2. Txoj hauv kev zoo tshaj plaws los txhim kho cov hluav taws xob hluav taws xob muaj peev xwm yog siv cov xim dub kho qhov chaw.
