Yog vim li cas rau sai thiab qeeb tshav kub dissipation ntawm LED heatsink

Lub hauv paus ntsiab lus ntawm kev ua haujlwm ntawm LED heatsink yog siv cov nti LED los ua kom muaj cua sov thaum ua haujlwm thiab ua kom nws mus rau qhov chaw ib puag ncig, thiaj li ua kom qhov kub thiab txias nyob ib puag ncig ntawm lawv tus kheej xav tau thiab ua kom lub teeb pom kev zoo ntawm LED teeb. Nws qhov kub dissipation ceev yog txiav txim siab los ntawm nws cov thermal kuj. Yog hais tias lub thermal kuj loj, qhov sib txuas kub yuav siab nyob rau tib lub sijhawm, ntawm qhov tsis sib xws, nws yuav qis. Qhov siab dua qhov sib txuas kub, qhov kev pab cuam lub neej luv ntawm lub nti, ntawm qhov tsis sib xws, lub neej ua haujlwm ntev dua. Lub thermal kuj muaj feem xyuam rau cov thermal tsis kam ntawm cov cua kub conduction thiab kub dissipation.

Qee qhov cuam tshuam ntawm cov cua sov dissipation thermal tsis kam ntawm lub heatsink yog qhov kub dissipation cheeb tsam thiab cov hluav taws xob coefficient ntawm cov khoom siv heatsink. Raws li txoj cai, qhov loj dua qhov kub dissipation cheeb tsam thiab qhov siab dua qhov hluav taws xob coefficient, qhov me dua qhov cua sov dissipation thermal kuj, thiab qhov zoo dua qhov kub dissipation ntawm heatsink. Txwv tsis pub, nws tsis zoo. Yog li ntawd, thaum xaiv lub heatsink, koj tuaj yeem xav txog qhov cuam tshuam ntawm cov cua sov ntawm lub heatsink los ntawm qhov ua tau zoo no. Qhov thib ob yog cov thermal conductivity, uas yog txiav txim siab los ntawm thermal conductivity. Qhov loj dua qhov thermal conductivity, qhov me dua qhov thermal kuj, qhov zoo dua thermal conductivity thiab zoo dua thermal conductivity nyhuv. Yog li ntawd, thaum xaiv cov khoom, peb tuaj yeem soj ntsuam cov thermal conductivity los txiav txim qhov kub dissipation ceev ntawm ib yam khoom.

Yog li ntawd, ib tug zoo coj heatsink xav tau ib tug tej yam tshav kub dissipation cheeb tsam, high radiation coefficient thiab loj thermal conductivity ntawm manufacturing cov ntaub ntawv, thiaj li yuav muaj ib tug zoo tshav kub dissipation nyhuv. Ntxiv mus, cov ntaub ntawv ntau lawm yuav tsum muaj qhov zoo ntawm corrosion kuj, yooj yim plasticity thiab tsawg ntom, thiaj li ua kom cov khoom zoo lawv xav tau. Sinda thermal yog cov kws tshaj lij heatsink tsim khoomr , peb tuaj yeem muab ntau hom heatsinks thiab txias txias uas suav nrog aluminium extruded heatsink, kev ua haujlwm siab heatsink, tooj liab heatsink, skived fin heatsink, kua txias phaj thiab cov yeeb nkab heatsink. thov hu rau peb yog tias koj muaj lus nug txog kev daws teeb meem thermal.
