Daim ntawv thov Thermal Pad hauv LED txias
Raws li peb txhua tus paub, LED teeb ua haujlwm ntev. Yog hais tias cov cua kub dissipation tsis zoo, lub neej kev pab yuav tsis ntev heev! Yuav ua li cas dissipate tshav kub nyob rau hauv LED txoj kev teeb yog ib tug thermal tsim teeb meem uas engineers yuav tsum xav txog. Kev siv cov thermal conductive PAD yog ib qho ntawm cov kev daws teeb meem thermal.
Thermal conductinve PAD nrog cov thermal conductivity thiab kev ua haujlwm siab yog tsuas yog siv ntawm nti thiab lub dab dej kub lossis lub plhaub ntawm cov khoom siv hluav taws xob. Nws yog me ntsis nplaum, mos thiab compressible
, uas yog tsim nyog rau lub tshav kub hloov.
Nyob sab hauv tsev LED teeb feem ntau siv cov khoom siv hluav taws xob uas muaj cov khoom siv hluav taws xob tsis muaj zog, uas tuaj yeem txo tus nqi ntawm cov khoom thiab ua tau raws li qhov xav tau ntawm cov khoom nws tus kheej. Rau qee qhov teeb pom kev zoo sab nraum zoov LED teeb, xws li cov teeb pom kev, lub zog ntawm txoj kev teeb yog ntau dua li lwm cov teeb hauv tsev, kom cov teeb pom kev zoo dua cov cua sov thiab txhim kho cov kev pab cuam lub neej ntawm cov teeb, Feem ntau, thermal conductive cov ntaub ntawv nrog Cov nyhuv thermal conductivity zoo yog siv, xws li theem hloov thermal conductive PAD.
Qhov zoo ntawm thermal PAD:
Nws muaj kev ua haujlwm ruaj khov dua thiab zoo thermal conduction. Nws feem ntau yog siv rau kev siv hluav taws xob ntawm cov khoom siv hluav taws xob siab. Nws muaj micro viscosity thiab ua haujlwm yooj yim. Nws tuaj yeem ncaj qha pasted nruab nrab ntawm aluminium substrate thiab kub dab dej ntawm LED teeb. Nws muaj qib siab ntawm adhesion, kom lub dab dej kub tuaj yeem tiv tauj nrog txhuas substrate, tso pa tawm, thiab zoo dua xa tawm cov cua sov los ntawm lub dab dej kub, uas zoo heev txo cov cua sov ntawm lub teeb nws tus kheej, Yog li, kev pab cuam lub neej teeb yog ntev.
