Yog vim li cas rau lub tshav kub dissipation ceev ntawm LED tshav kub dab dej
Jun 18, 2022| Yog vim li cas rau lub tshav kub dissipation ceev ntawm LED tshav kub dab dej
Koj puas paub tias qhov ceev ntawm LED cov dab dej kub yog cuam tshuam li cas? Tsuas yog los ntawm kev qhia meej qhov no peb tuaj yeem paub txiav txim qhov zoo ntawm lub tshuab hluav taws xob. Cia kuv qhia rau koj qee qhov laj thawj uas kuv paub tias cuam tshuam rau lub tshav kub dissipation ceev ntawm lub radiator.
Ua ntej tshaj plaws, cia peb tham txog nws txoj hauv kev ua haujlwm, uas yog siv cov nti LED los ua kom sov thiab dissipate nws mus rau ib puag ncig ib puag ncig thaum nws ua haujlwm, kom qhov kub thiab txias ntawm lub lim tiam yog khaws cia nyob rau hauv qhov ntau uas nws xav tau los xyuas kom meej. lub teeb pom kev zoo ntawm LED teeb. Thiab 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, thiab ntawm qhov tsis sib xws, nws yuav qis. Qhov siab dua qhov sib txuas kub, lub neej luv ntawm lub nti, thiab rov ua dua. Lub thermal tsis kam yog muaj feem xyuam rau ob qhov chaw, thermal conduction thiab tshav kub dissipation thermal kuj.
Tom qab ntawd cia peb tham txog qee yam cuam tshuam ntawm cov cua sov dissipation thermal tsis kam ntawm lub tshuab hluav taws xob, uas yog, thaj chaw tshav kub thiab qhov hluav taws xob coefficient ntawm cov khoom siv ntawm lub tshuab hluav taws xob. Nyob rau hauv txoj kev xav, qhov loj dua qhov kub dissipation cheeb tsam thiab qhov siab dua qhov hluav taws xob coefficient, qhov me me ntawm cov cua sov dissipation thermal kuj yuav, thiab qhov zoo dua qhov kub dissipation ntawm radiator yuav. . Qhov thib ob yog lub thermal tsis kam ntawm thermal conductivity. Thermal conductivity yog tsuas yog txiav txim siab los ntawm thermal conductivity coefficient los txiav txim nws cov thermal conductivity. Qhov loj dua qhov thermal conductivity coefficient, qhov me dua qhov thermal conductivity thermal kuj, qhov thermal conductivity zoo dua thiab zoo dua thermal conductivity nyhuv. Yog li ntawd, thaum xaiv cov khoom, peb kuj tuaj yeem soj ntsuam cov thermal conductivity los ntawm kev lis kev cai los txiav txim qhov kub dissipation ceev ntawm ib yam khoom.
