Dab tsi yog cov ntaub ntawv thermal rwb thaiv tsev rau lub hwj chim adapter?
Fais fab Adapter
Fais fab adapter yog lub zog hloov khoom siv rau cov khoom siv hluav taws xob me me thiab cov khoom siv hluav taws xob. Nws yog dav siv nyob rau hauv lub xov tooj ntawm tes handsets, game consoles, lus repeaters, walkmans, notebook computers, cellular xov tooj thiab lwm yam khoom siv. Lub hwj chim adapter feem ntau yog tsim los ntawm lub plhaub, lub hwj chim transformer thiab lub rectifier circuit. Raws li nws cov zis hom, nws yuav muab faib ua AC tso zis hom thiab DC tso zis hom; raws li hom kev sib txuas, nws tuaj yeem muab faib ua phab ntsa thiab hom duab desktop. Fais fab adapters yog dav siv nyob rau hauv industrial automation tswj, tub rog khoom, scientific kev tshawb fawb cov cuab yeej, LED teeb pom kev zoo, industrial tswj cov cuab yeej, kev sib txuas lus, khoom siv hluav taws xob, instrumentation thiab lwm yam.
Txij li thaum muaj ntau cov khoom siv hluav taws xob semiconductor siv hauv cov khoom siv fais fab, xws li choj rectifiers, high-tam sim no rectifiers, high-power transistors lossis field effect transistors, lawv yuav ua kom muaj cua sov ntau thaum lawv ua haujlwm. Thaum lub tshuab hluav taws xob kub siab tshaj 75 ° C, Yog tias cov cua sov tsis tuaj yeem tawm hauv lub sijhawm thiab khaws cia ntawm qhov tsim nyog, kev ua haujlwm ntawm lub hwj chim adapter yuav raug cuam tshuam, thiab lub hwj chim adapter yuav raug puas tsuaj rau qhov mob hnyav. Feem ntau, fais fab adapter manufacturers siv ib co thermally conductive insulating cov ntaub ntawv los pab lub hwj huam mov dissipate tshav kub thaum tsim thiab ntau lawm. Dab tsi yog cov khoom siv thermally conductive insulating rau lub hwj chim adapter txias daws?
Thermally conductive potting kua nplaum
Thermally conductive kua nplaum potting muab faib ua ib nrab potting thiab tag nrho potting. Sab hauv ntawm lub hwj chim adapter yog tsis sib xws thiab tsis xwm yeem. Dab tsi yog qhov xav tau yog cov khoom siv thermally conductive uas tuaj yeem qhwv lub transformer tag nrho thiab tsis tuaj yeem txav ntawm qhov siab. Hauv zos potting feem ntau yog concentrated thaum tshav kub kub loj thiab tsis tuaj yeem hloov los ntawm lwm cov ntaub ntawv thermally conductive. Tag nrho cov potting yog vim ib feem ntawm cov khoom siv hluav taws xob yuav tsum ua haujlwm sab nraum zoov ntev. Ntxiv nrog rau kev daws qhov teeb meem thaum tshav kub kub dissipation, lub waterproof thiab airtightness ntawm lub hwj huam mov yuav tsum tau txiav txim siab. Yog li ntawd, sab nraum zoov fais fab mov yeej siv tag nrho cov potting kom dissipate cua sov.
Thermal conductive silicone daim ntawv
Rau kev lag luam hluav taws xob, qhov kev faib ua feem ntawm thermal silica gel daim ntaub ntawv feem ntau yog me me, tab sis qee zaum nws yog qhov tseem ceeb. Feem ntau, daim ntawv thov ntawm thermal silica gel films rau lub hwj chim adapters yog mas concentrated nyob rau hauv lub PCB board. Ib daim ntawv thov tshwj xeeb thiab kev thov yuav tsum Muaj cov khoom tshwj xeeb kom tau raws li nws. Cov ntawv thermally conductive silicone yog siv rau PCB board, uas muaj thermal conductivity, hluav taws xob rwb thaiv tsev, poob siab thiab puncture kuj thiab lwm yam dej num, uas muaj peev xwm daws tau qhov teeb meem kev nyab xeeb rau tus neeg siv.
Ib qho khoom siv silicone
Ib qho khoom siv silica gel feem ntau yog siv rau kev siv hluav taws xob hauv zos ntawm cov khoom siv hluav taws xob, thiab tib lub sijhawm nws tuaj yeem ua lub luag haujlwm ntawm kev kho cov khoom. Nws muaj qhov zoo adhesion thiab sealing zoo rau cov hlau thiab tsis yog hlau.
Thermally conductive silicone cloth Feem ntau siv rau hauv lub hwj chim MOS raj ntim, cov qauv txheem qhov chaw TO-220, TO-3P, thiab lwm yam, feem ntau yog siv ib txheej ntawm silicone roj rau ntawm daim ntawv silicone thiab MOS raj kom cov adhesion thiab txo cov thermal kuj.
Alumina ceramics
Txawm hais tias nws yog thermal conductivity, kub tsis kam ntau lossis kev ua haujlwm rwb thaiv tsev, nws deb tshaj qhov thermal conductivity silicone daim ntaub, uas tuaj yeem siv los hloov txoj haujlwm ntawm silica gel hauv MOS raj. Muaj cov txheej txheem rau TO-220 thiab TO-3P series, uas yuav tsum tau nce ntxiv los ntawm kev siv cov roj silicone. Qhov chaw tiv tauj ntawm MOS raj.
