Kev tswj cua sov ntawm cov khoom siv hnav xws li VR / AR
Cov khoom siv hluav taws xob siv hluav taws xob xa mus rau cov khoom siv hluav taws xob tsim los ntawm cov neeg siv khoom siv uas cuam tshuam nrog lub neej, kev ua haujlwm, thiab kev lom zem. Kev tshwm sim ntawm cov neeg siv khoom siv hluav taws xob yog qhov hloov pauv loj hauv lub neej niaj hnub, uas txhim kho kev yooj yim thiab kev ua neej zoo ntawm cov neeg siv khoom thiab dhau los ua ib qho tseem ceeb ntawm lawv lub neej niaj hnub.
Raws li txoj kev loj hlob ntawm cov neeg siv khoom siv hluav taws xob tsim khoom siv thev naus laus zis thiab qhov nrov ntawm cov ntawv thov hauv internet, cov neeg siv khoom siv hluav taws xob txuas ntxiv nthuav dav. Tam sim no, txawm hais tias cov khoom siv hluav taws xob ib txwm siv ua lag luam sawv cev los ntawm smartphones, ntsiav tshuaj, thiab laptops tau nce zuj zus thiab loj hlob ntawm qeeb qeeb, raws li cov ceg tshiab ntawm cov neeg siv khoom siv hluav taws xob, cov khoom siv hluav taws xob ntse uas sawv cev los ntawm VR / AR tseem tab tom tsim.
Tag nrho cov qauv kev lag luam ntawm cov khoom siv ntse ntse thiab cov khoom siv hluav taws xob siv tau zoo ib yam: sab saud yog cov khoom siv raw thiab cov khoom siv; Midstream manufacturers; Hauv qab yog cov khoom siv coj los siv. Ntawm lawv, kev tsim khoom ntawm cov khoom siv nruab nrab thiab kev tsim cov khoom siv kho qhov muag downstream yog tus yuam sij rau cov khoom siv ntse ntse, nrog cov ntsiab lus thev naus laus zis siab thiab kev nqis peev tseem ceeb. Tib lub sijhawm, lawv kuj yog qhov sib tw hnyav tshaj plaws thiab muaj kev pheej hmoo siab hauv kev sib tw thoob ntiaj teb. Nyob rau tib lub sijhawm, nrog rau kev txhim kho txuas ntxiv ntawm cov khoom siv ntse ntse, cov kev xav tau siab dua tau muab tso rau pem hauv ntej rau kev ua haujlwm kub dissipation ntawm cov khoom siv.
Raws li kev ua haujlwm sib txawv, cov khoom siv thermal tswj tau muab faib ua ob hom: active (active) thiab passive (passive). Cov khoom siv cua txias feem ntau siv lub hauv paus ntsiab lus ntawm thermal convection kom yuam cov cua sov los ntawm cov khoom siv cua sov, xws li cov kiv cua, liauid twj tso kua mis hauv cov kua txias, thiab compressors hauv theem hloov tub yees. Cov yam ntxwv ntawm cov khoom siv txias txias heatsink yog kev ua haujlwm siab, tab sis nws yuav tsum tau txais kev pab los ntawm lwm lub zog. Passive heat dissipation feem ntau siv lub hauv paus ntsiab lus ntawm kev siv hluav taws xob lossis hluav taws xob, feem ntau yog nyob ntawm cov khoom cua sov lossis cov fins kom txias. Nyias thiab lub teeb yuag cov khoom siv hluav taws xob xws li mobile terminals thiab ntsiav tshuaj feem ntau yog siv vim muaj kev txwv sab hauv spatial. Cov txheej txheem hluav taws xob tsis zoo muaj xws li graphite tshav kub dissipation zaj duab xis, graphene zaj duab xis, cov yeeb nkab kub, thiab cov phaj ntub dej. Txhawm rau ua kom muaj cua sov zoo, kev siv cov khoom siv hluav taws xob sib txuas ntawm cov khoom siv cua sov thiab cua txias feem ntau yuav tsum tau, xws li hlau brazing txheej, thermal conductive silicone, thermal conductive paste, thiab lwm yam.
Hauv kev siv cov xwm txheej, cov ntaub ntawv tswj xyuas thermal thiab cov khoom siv feem ntau yuav tsum tau ua ke rau kev siv. Siv IGBT cov khoom siv hluav taws xob siv dav siv hauv tsheb tshiab lub zog ua piv txwv, txoj kev hloov hluav taws xob ntawm cov nti mus rau sab nraud suav nrog cov txheej txheem vuam txheej (hlau), DCB / AMB ceramic circuit board txheej (xws li ceramic substrate txheej thiab tooj liab txheej txheej) , txheej txheej vuam txheej (hlau), hlau substrate, cov khoom sib txuas (thermal conductive silicone grease), thiab lub dab dej kub. Thaum kawg, lub dab dej kub thiab huab cua ua rau cov hluav taws xob hloov hluav taws xob thiab hluav taws xob hloov hluav taws xob, thiab muaj kev ua haujlwm thermal thoob plaws hauv tag nrho cov txheej txheem kev coj ua, Thermal resistance yog qhov tseem ceeb cuam tshuam rau cov cua kub dissipation ntawm IGBT fais fab modules.
Txhawm rau txhim kho cov nyhuv thermal dissipation, txo cov thermal kuj yog txoj kev tseem ceeb tshaj plaws. Nrog rau kev txhim kho txuas ntxiv ntawm kev ua haujlwm ntawm cov nti, cov cuab yeej siv me me, thiab cov kev xav tau sib sib zog nqus, kev lag luam cov kev xav tau rau kev tswj xyuas thermal kuj tseem nce ntxiv. Cov kws tshawb fawb txog kev tswj cov cua sov yuav tsum tau hloov pauv siv cov txheej txheem kev tswj xyuas kev ua haujlwm zoo, nrog rau kev npaj thiab sib txuas cov substrates, cov dab dej kub, thiab cov khoom siv thermal interface. Piv txwv li, IGBT modules tuaj yeem ua ke nrog cov phaj ntub dej, cov thermoelectric modules, thiab txawm tias cov kua txias txias kom ua tiav cov cua sov zoo dua.
