Power Suppy adapter thermal tsim
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 cov ntsiav tshuaj computers, game consoles, lus repeaters, Walkman, notebook computers, cellular xov tooj thiab lwm yam khoom siv.
Fais fab adapter feem ntau yog tsim los ntawm lub plhaub, lub hwj chim transformer thiab 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 adapter yog dav siv nyob rau hauv industrial automation tswj, tub rog cov cuab yeej, scientific kev tshawb fawb khoom, LED teeb pom kev zoo, industrial tswj cov cuab yeej, kev sib txuas lus, khoom siv hluav taws xob, twj paj nruag thiab lwm yam kev lag luam.
Vim tias muaj ntau lub zog hluav taws xob semiconductor siv nyob rau hauv lub hwj chim adapter, xws li rectifier choj, high-tam sim no rectifier, high-power triode los yog field effect transistor, lawv yuav ua rau kub heev thaum lawv ua hauj lwm. Thaum lub hwj huam mov kub siab tshaj 75 degree, yog tias cov cua sov no tsis tuaj yeem tawm hauv lub sijhawm thiab khaws cia ntawm qhov tsim nyog, Nws yuav cuam tshuam rau kev ua haujlwm ntawm lub hwj chim adapter thiab ua rau lub hwj chim adapter puas tsuaj.
Thermal conductive potting nplaum:
Lub thermal conductive nplaum potting yog muab faib ua ib nrab potting thiab zuag qhia 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 thermal conductive uas tuaj yeem qhwv lub transformer tag nrho thiab tsis tuaj yeem txav mus los ntawm qhov siab. Ib nrab potting feem ntau yog concentrated nyob rau hauv cov ntaub ntawv ntawm high calorific nqi thiab tsis tuaj yeem hloov los ntawm lwm cov khoom siv hluav taws xob. Kev sib xyaw ua ke yog vim qee qhov khoom siv hluav taws xob yuav tsum ua haujlwm sab nraum zoov ntev. Ntxiv nrog rau kev daws qhov teeb meem ntawm cov cua sov dissipation, peb yuav tsum xav txog cov dej tsis zoo thiab kev sib khi ntawm cov khoom siv hluav taws xob. Yog li ntawd, cov khoom siv hluav taws xob sab nraum zoov pib siv cov khoom siv hluav taws xob rau cov cua sov dissipation.
Thermal PAD:
Rau kev lag luam fais fab, daim ntawv thov feem ntawm thermal conductive PAD feem ntau yog me me, tab sis qee zaum nws yog qhov tseem ceeb. Feem ntau, daim ntawv thov ntawm thermal PAD nyob rau hauv lub hwj chim adapter yog mas concentrated ntawm PCB board. Daim ntawv thov tshwj xeeb thiab kev thov yuav muaj cov khoom tshwj xeeb kom tau raws li nws. Thermal PAD yog siv rau ntawm PCB board, uas muaj cov thermal conductivity efficiency, hluav taws xob rwb thaiv tsev Shockproof, puncture pov thawj thiab lwm yam dej num, uas muaj peev xwm daws tau cov teeb meem thermal.
Thermal roj:
Nws feem ntau yog siv rau hauv lub hwj chim MOS raj ntim. Cov qauv txheej txheem TO-220 thiab rau -3p feem ntau yog coated nrog ib txheej ntawm silicone roj ntawm silicon zaj duab xis thiab MOS raj kom ua rau adhesion thiab txo cov thermal kuj.
Thermal tsim yog ib qho tseem ceeb heev nyob rau hauv txhua qhov kev lag luam, tag nrho cov khoom siv hluav taws xob yuav tsim kom muaj cua sov thaum ua haujlwm, nrog rau kev tsim thermal zoo heev lub tempurature tuaj yeem ua kom txias rau lub sijhawm, uas yuav pab tau zoo kom cov cuab yeej ua haujlwm ruaj khov thiab kev pabcuam ntev. lav. Sinda Thermal yog cov chaw tsim khoom siv thermal, thov ua haujlwm nrog peb yog tias koj muaj teeb meem thermal.
