Thermal tswj ntawm fais fab adapter
Fais fab adapter yog cov khoom siv hluav taws xob me me thiab cov khoom siv hluav taws xob hluav taws xob hluav taws xob hloov hluav taws xob, txhawb nqa lub xov tooj me nyuam lub tshuab, tshuab ua si, lus rov hais dua, walkman, phau ntawv computer, xov tooj ntawm tes 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 kev sib txuas hom tuaj yeem muab faib ua phab ntsa hom thiab desktop hom. Fais fab adapter yog dav siv nyob rau hauv industrial automation tswj, tub rog cov cuab yeej, kev tshawb fawb cov cuab yeej, LED teeb pom kev zoo, muaj kev tswj cov cuab yeej, kev sib txuas lus, khoom siv fais fab, instrumentation thiab lwm yam.
Vim lub hwj chim adapter yog siv nyob rau hauv ib tug loj npaum li cas ntawm high-power semiconductor pab kiag li lawm, xws li rectifier choj pawg, loj tam sim no rectifier raj, lub hwj chim transistor los yog field effect tube li, xws li lawv ua hauj lwm yuav ua tau ib tug ntau ntawm tshav kub, lub hwj chim mov kub. ib zaug ntau dua 75 degree, yog tias tsis tuaj yeem tshem tawm cov cua sov kom raws sijhawm thiab nyob rau theem tsim nyog,
Kev ua haujlwm ib txwm ntawm lub hwj chim adapter raug cuam tshuam, thiab hauv qhov xwm txheej hnyav, lub hwj chim adapter puas lawm.
Feem ntau, lub hwj chim adapter manufacturers yuav siv ib co thermal rwb thaiv tsev ntaub ntawv los pab lub hwj chim mov thaum tshav kub kub dissipation nyob rau hauv tsim thiab ntau lawm. Dab tsi yog cov ntaub ntawv thermal rwb thaiv tsev feem ntau siv nyob rau hauv cov txheej txheem kub dissipation ntawm lub hwj chim adapter?
Thaum tshav kub kub conduction potting nplaum
Thermal conductive nplaum potting muab faib ua sub-division 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 tau dawb.
Cov potting hauv zos feem ntau yuav muaj zog hauv cov cua sov, thiab tsis tuaj yeem hloov los ntawm lwm cov khoom siv thermal conductive.
Tag nrho cov potting yog vim hais tias ib feem ntawm lub hwj huam mov yuav tsum ua hauj lwm sab nraum lub sij hawm ntev. Ntxiv nrog rau kev daws qhov teeb meem ntawm cov cua sov, cov khoom siv dej tsis zoo thiab kev sib khi ntawm cov khoom siv hluav taws xob yuav tsum raug coj mus rau hauv tus account, yog li cov khoom siv hluav taws xob sab nraum zoov yeej siv tag nrho cov potting rau cov cua sov dissipation.
Thermal conductive silica gel
Thermal conductive silicone piece rau lub hwj chim kev lag luam, qhov feem ntawm nws daim ntawv thov feem ntau yog tsawg, tab sis tej zaum nws tseem yog ib qho tseem ceeb, lub hwj chim adapter ntawm daim ntawv thov ntawm thermal conductive silicone daim feem ntau tsom rau PCB, yuav muaj ib tug tshwj xeeb daim ntawv thov thiab thov ib tug tshwj xeeb hom. ntawm cov khoom kom tau raws li nws, thermal conductive silicone daim ntawv thov ntawm PCB board,
Nrog kev ua haujlwm siab thermal conductivity, hluav taws xob rwb thaiv tsev, kev poob siab thiab kev tiv thaiv kev sib tsoo thiab lwm yam haujlwm, tuaj yeem daws qhov teeb meem kev nyab xeeb rau cov neeg siv khoom.
Ib feem ntawm silica gel
Ib qho kev tivthaiv silica gel feem ntau yog siv nyob rau hauv lub zos tshav kub conduction ntawm lub hwj chim Cheebtsam, tab sis kuj muaj peev xwm ua si lub luag hauj lwm ntawm taag Cheebtsam, rau hlau thiab non-metals muaj zoo adhesion thiab sealing.
Thermal conductive silicon roj hmab
Feem ntau siv rau hauv cov khoom siv hluav taws xob MOS raj ntim, cov khoom siv sib xyaw ua ke, xws li TO-220 thiab TO-3P, feem ntau yog coated nrog ib txheej ntawm silicone roj rau ntawm daim ntawv silica gel thiab MOS raj los ua kom cov haum thiab txo cov thermal kuj.
Alumina ceramic
Ob leeg thermal conductivity, kub ntau thiab rwb thaiv tsev kev ua tau zoo nyob deb ntawm superconducting kub silicone, uas tuaj yeem siv los hloov txoj haujlwm ntawm silica gel hauv MOS raj. Rau TO-220 thiab rau -3P series, muaj cov qauv txheem, yog li nws yog qhov tsim nyog los ua kom thaj chaw tiv tauj nrog MOS raj los ntawm kev siv cov roj silicone.
Sinda Thermal yog cov chaw tsim khoom siv hluav taws xob ua hluav taws xob hauv hluav taws xob, peb lub Hoobkas yog tsim los ntawm pab pawg kws tshaj lij thermal thiab ntau yam khoom siv presice, peb muab cov nqi sib tw tshaj plaws thiab cov khoom siv hluav taws xob zoo rau cov neeg siv khoom hauv ntiaj teb. Thov hu rau peb dawb yog tias koj muaj kev xav tau thermal.
