LED teeb pom kev zoo teeb meem kub dissipation: Tsib hom kev sib piv ntawm cov dab dej kub

May 21, 2024|

Tam sim no, ib qho ntawm cov teeb meem loj tshaj plaws ntawm LED teeb pom kev zoo yog qhov teeb meem kub dissipation, tsis zoo cua sov dissipation ua rau LED tsav fais fab mov, electrolytic capacitors tau dhau los ua qhov tsis muaj zog txuas rau kev txhim kho ntxiv ntawm LED teeb pom kev zoo, LED teeb pom kev tsis ua haujlwm ntxov. .

Tsuas yog xa tawm sai sai yuav pab tau kom txo tau cov kab noj hniav kub nyob rau hauv lub LED teeb thiab lanterns, muaj peev xwm tuav lub hwj chim mov tsis nyob rau hauv lub check kub kub ib puag ncig, thiaj li yuav tiv thaiv lub LED teeb qhov chaw vim lub sij hawm ntev kub kub ua hauj lwm thiab ntxov ntxov ua tsis tiav.

Vim hais tias lub teeb ci LED nws tus kheej tsis muaj infrared, ultraviolet, yog li LED lub teeb qhov chaw nws tus kheej tsis muaj hluav taws xob ua kom txias, LED teeb pom kev zoo cua sov dissipation txoj kev tsuas yog los ntawm kev sib xyaw ua ke ntawm LED teeb hlaws phaj kub dab dej rau xa tawm cov cua sov. . Thaum tshav kub kub dab dej yuav tsum muaj cua sov conduction, cua sov convection, tshav kub tawg.

Txhua lub dab dej kub, ntxiv rau kom muaj peev xwm ua kom muaj cua sov sai sai ntawm qhov chaw sov mus rau lub dab dej kub sab nrauv, qhov tseem ceeb yog tseem cia siab rau convection thiab hluav taws xob kom tawm cua sov mus rau saum huab cua. Thermal conduction tsuas yog cuam tshuam nrog txoj kev hloov mus rau cov cua sov, thaum thermal convection yog lub luag haujlwm tseem ceeb ntawm lub dab dej kub, qhov kev ua haujlwm ntawm cov cua sov yog feem ntau cuam tshuam los ntawm lub peev xwm ntawm tshav kub dissipation cheeb tsam, zoo li, thiab ntuj convection lub zog, thiab thermal tawg. tsuas yog lub luag haujlwm pab. Feem ntau hais lus, yog tias cov cua sov los ntawm lub tshav kub mus rau sab nrauv ntawm lub dab dej kub yog tsawg dua 5 millimeters, ces tsuas yog thaum cov khoom siv thermal conductivity ntau dua 5, lub tshav kub tuaj yeem raug xa tawm, lwm qhov kub dissipation yuav tsum tau dominated. thermal convection.

Feem ntau ntawm LED teeb pom kev zoo tseem siv hluav taws xob tsawg (VF=3.2V), siab tam sim no (IF=200-700mA) LED teeb hlaws, vim tias muaj cua sov thaum ua haujlwm, nws yuav tsum tau siv nrog siab. thermal conductivity ntawm aluminium alloy. Muaj feem ntau tuag-cam khwb cia txhuas cua sov dab dej, extruded aluminium kub dab dej, stamped aluminium kub dab dej. Tuag casting aluminium kub dab dej yog ib hom kev siab casting qhov chaw txawj, cov kua zinc tooj liab aluminium alloy pouring rau hauv tuag casting tshuab inlet, los ntawm tuag casting tshuab tuag casting, casting ua ntej npaj pwm txwv cov duab tshav kub dab dej.


Cov hauv qab no yog ib qho kev sib piv ntawm tsib hom cua sov dab dej.

Tuag-casting aluminium kub dab dej
Tus nqi tsim khoom tuaj yeem tswj tau, lub dab dej kub hauv lub dab dej tsis tuaj yeem ua kom nyias nyias, nws yog qhov nyuaj rau kev ua kom cov cua sov ua kom sov.
