Feem ntau UV LED thermal txias txoj kev
UV-LED yog ib qho khoom siv hluav taws xob tshiab UV lub teeb tom qab ib txwm siv roj UV teeb xws li mercury teeb thiab xenon teeb. Nws muaj qhov zoo ntawm kev ua haujlwm ruaj khov, ib qho hloov kho lub teeb yoj, siab luminous efficiency, qis zog noj, ntsuab ib puag ncig tiv thaiv thiab lwm yam. Nws tau dhau los ua cov khoom hloov pauv zoo tshaj plaws hauv feem ntau daim ntawv thov UV tam sim no. Nyob rau hauv xyoo tas los no, nrog rau kev loj hlob sai ntawm UV-LED thiab kev txhim kho txuas ntxiv ntawm nws lub zog hluav taws xob, cov cua sov dissipation tau dhau los ua qhov tseem ceeb cuam tshuam nws txoj kev loj hlob. Qhov nce ntawm nti hlws ris kub ua rau poob ntawm UV-LED kev ua tau zoo. Yuav kom tswj tau cov yam ntxwv zoo ntawm UV-LED system nyob rau hauv lub zog muaj zog, peb yuav tsum ntxiv dag zog rau lub thermal txias ntawm nti.
UV-LED cua txias heatsink:
UV-LED Cua txias heatsink tuaj yeem muab faib ua hom extrusion thiab kub yeeb nkab hom raws li qeb. Vim yog lub zog loj ntawm array UV-LED chips, ntuj convection tuaj yeem muab cov cua sov me me thiab kev siv cua sov siab, yog li kev quab yuam convection feem ntau yog siv los ntawm ntuj convection.
Lub extrusion cua txias heatsink feem ntau yog siv rau lub hwj chim qis UV-LED txias, thiab nws muaj kev ntseeg siab thiab tus nqi qis dua vim cov qauv yooj yim.
Thaum tshav kub kub yeeb nkab yog ib tug high-efficiency tshav kub conduction ntaus ntawv, uas tsuas yog siv theem hloov tshav kub hloov. Cov yeeb nkab cua sov nws tus kheej tsis muaj qhov ua kom txias, tab sis yog cov khoom siv hluav taws xob zoo. Fins feem ntau yog muab faib rau sab nraum U-zoo li lub tshav kub yeeb nkab, uas ua tau raws li qhov yuav tsum tau ntawm miniaturization thiab yooj yim ntawm UV curing system thiab xyuas kom meej lub uniformity ntawm tshav kub dissipation nto kub.
UV-LED kua txias daws teeb meem
Cov kua cua txias heatsink tsav cov kua ntws los ntawm lub twj tso kua mis kom tshem tawm cov cua sov. Cov kua cua txias radiator feem ntau yog siv dej ua lub coolant. Vim tias cov thermal conductivity ntawm cov dej nyob rau tib qhov kub yog li ntawm 20 npaug ntawm huab cua, nws lub peev xwm hloov hluav taws xob ntau dua li ntawm huab cua, thiab qhov tshwj xeeb kub ntawm cov dej muaj peev xwm loj dua li huab cua, yog li nws tuaj yeem nqus tau zoo. Thaum tshav kub kub tsim los ntawm UV-LED chips. Cov kua cua txias radiator ntawm compact UV-LED ntaus ntawv tuaj yeem ua ke rau hauv daim ntawv thov nrog qhov chaw txwv nyob ib ncig ntawm thaj chaw kho, thiab siv dav hauv ntau zaus.
Txoj kev txias txias tshiab:
Ntxiv nrog rau cov cua txias cua txias cua sov thiab cov kua cua txias cua sov, txhawm rau ua kom sov UV-LED system, qee qhov cua sov tshiab tau tshwm sim, xws li rmoelectric tub yees, kua hlau txias thiab lwm yam.
Nyob rau hauv cov txheej txheem ntawm thermoelectric tub yees thiab cua kub dissipation, semiconductor tub yees daim ntawv (TEC) tsuas yog siv los ua cov khoom siv hluav taws xob. Tec muaj cov qauv compact, thiab cov cua kub flux uas muaj peev xwm dissipate tshav kub feem ntau yog tsawg, thiab nws yog feem ntau yog siv rau tshav kub dissipation ntawm low-power UV systems, thiab ces lub tshav kub yog tawm los ntawm lwm txoj kev txias.
Qhov teeb meem ntawm cov cua kub dissipation tau dhau los ua ib qho kev tsis sib haum xeeb uas txwv kev txhim kho lub zog ntawm UV-LED system. Qhov teeb meem ntawm tshav kub dissipation ntawm high-power UV-LED yuav tsum tau daws los ntawm combining tshav kub hloov lwm lub tsev, cov ntaub ntawv science thiab manufacturing technology. Thaum tshav kub kub hloov pauv muab cov cua kub dissipation txhais tau tias, cov ntaub ntawv tshawb fawb txhim kho cov thermal conductivity ntawm cov ntaub ntawv, thiab kev tsim technology txhim kho cov txheej txheem tsim khoom.
Cua txias thiab kua cua txias heatsinks yog cov cuab yeej siv dav tshaj plaws tam sim no. Tsis tas li ntawd, txoj kev ua kom txias tshiab xws li cov tub yees thermoelectric thiab kua hlau kuj tau tshwm sim. Txawm li cas los xij, hauv kev txhim kho thev naus laus zis thev naus laus zis, tseem muaj ntau qhov chaw tsim nyog tshawb nrhiav, thiab kev tshawb fawb ntawm cov txheej txheem txias tshiab xav tau kev txhim kho ntxiv. Nyob rau hauv cov qauv tsim ntawm cua txias heatsink, kev tshawb fawb kev taw qhia nyob rau hauv xyoo tas los no yog los txhim kho cov qauv uas twb muaj lawm los ntawm optimization txoj kev, xaiv cov khoom siv thiab technology.
