Tham txog cov txheej txheem kub dissipation twg yog qhov zoo dua rau automotive LED headlights?
Hais txog cov lus nug ntawm" Qhov twg ntawm cov cua sov dissipation yog zoo dua rau tsheb LED teeb?" tib neeg muaj kev xav thiab kev xav sib txawv, tam sim no cia's tham txog cov ncauj lus no.
Tam sim no, muaj peb lub ntsiab thermal txoj kev siv nyob rau hauv automotive LED headlights ntawm lub khw. Txhawm rau kom paub meej tias tus qauv tsim twg yog qhov zoo dua, nws yuav tsum tau txiav txim siab sib cais los ntawm ntau yam xws li siv cov xwm txheej, qhov chaw teeb tsa, thiab siv tus cwj pwm.
Cia kuv ua ntej tham txog muaj pes tsawg txoj hauv kev kom dissipate tshav kub los ntawm automotive LED headlights?
1. Thaum tshav kub kub dab dej (daim ntawv) kub dissipation Qhov no yog ib tug thaum ntxov LED ntau lawm tswvyim. Muaj tsuas yog ib lub dab dej kub rau cov cua sov dissipation, tsis muaj kiv cua, thiab tsis muaj cua sov dissipation tooj liab daim kab xev. Qhov kom zoo dua yog cov qauv yooj yim thiab tus nqi qis, tab sis qhov tsis zoo yog tias cov cua sov dissipation nyhuv tsis zoo thiab kev ua haujlwm tsis ruaj khov. Tam sim no nws tsis tshua siv;
2. Copper daim kab xev thermal txoj kev siv braided tooj liab strips rau txias. Vim hais tias tooj liab strips yuav folded thiab khoov, lub installation yog kuj yooj yim, thiab installation qhov yuav tsum tau tsis siab. Qhov no yog qhov zoo dua; tab sis qhov tsis zoo yog: tsis muaj cua sov dissipation, kev ua haujlwm tsis zoo, thiab lub teeb tawg Zoo sib xws, lub zog tawg sai dua, thiab lub zog tawg, thiab qhov ci ntsa iab. Qhov no yog vim li cas qhov ci ntsa iab ntawm LED teeb lub taub hau uas siv tooj liab kom dissipate lub teeb yuav maj mam txo tom qab 20 mus rau 30 feeb.
3. cua sov dab dej + kiv cua txias cua sov dab dej ntxiv kiv cua, radiator txias yog passive txias, kiv cua txias yog active txias, combining ob ua ke, nyob rau tib lub teeb taws LED, ob chav txias, ntau yam teebmeem, qhov no yog qhov zoo tshaj plaws. Thaum tshav kub kub dissipation txoj kev rau automotive LED headlights kom deb li deb.
