Txoj kev loj hlob ntawm Thermal Interface Material
Qhov kub thiab txias tuaj yeem ua rau muaj kev phom sij rau kev ruaj ntseg, kev cia siab, thiab lub neej ntev ntawm cov khoom siv hluav taws xob. Feem ntau muaj qhov sib txawv me me ntawm cov khoom siv hluav taws xob thiab cov dab dej kub, uas ua rau thaj chaw sib cuag tsuas yog 10% ntawm lub hauv paus cheeb tsam ntawm lub dab dej kub, uas cuam tshuam rau kev hloov hluav taws xob. Kev siv cov khoom siv thermal interface los sau cov qhov khoob tuaj yeem txo qhov kev sib cuag thermal tiv thaiv, thiab xyuas kom meej tias cov cua sov uas tsim los ntawm cov khoom siv hluav taws xob cua sov tau tawm hauv lub sijhawm.
Nrog rau qhov tshwm sim ntawm lub sijhawm ntawm Internet ntawm Yam, kev koom ua ke ntawm cov khoom siv hluav taws xob txuas ntxiv txhim kho. Tsis tas li ntawd, kev taw qhia ntawm cov teeb liab siab zaus thiab kev kho dua tshiab ntawm cov khoom siv kho vajtse tau ua rau muaj ob npaug ntawm cov khoom siv txuas nrog thiab cov kav hlau txais xov, uas ua rau muaj kev siv hluav taws xob tsis tu ncua thiab kev tsim hluav taws xob sai. Cov khoom siv hluav taws xob sib txuas muaj cov thermal conductivity zoo heev thiab muaj zog ib puag ncig adaptability, uas muab kev pabcuam muaj zog rau kev sib koom ua ke siab thiab cov khoom siv me me, thiab xav tias yuav dhau los ua kev cuam tshuam thiab hloov pauv thermal tswj kev daws teeb meem.
Nyob rau hauv cov nqe lus ntawm kev lag luam, kev lag luam hluav taws xob, uas sawv cev los ntawm peb qhov chaw kub kub, tso rau pem hauv ntej ntau thiab ntau qhov kev thov rau cov txheej txheem thermal tswj siab thiab cov khoom siv thermal interface:
Cov khoom siv hluav taws xob ntse ntse:Cov khoom siv hluav taws xob ntawm cov xov tooj smartphones thiab cov ntsiav tshuaj muaj cov qauv nruj thiab sib xyaw ua ke, thiab kev txhim kho txuas ntxiv ntawm cov cua kub ceev tau ua rau muaj kev xav tau ntau ntxiv rau kev tswj xyuas cua sov.
Cov khoom siv sib txuas lus:Cov khoom siv sib txuas lus tau dhau los ua ntau thiab nyuaj, kev siv hluav taws xob tau nce ntxiv, thiab cov nqi hluav taws xob tau nce sai, uas yuav ua rau muaj kev xav tau ntau ntxiv rau cov khoom siv thermal interface.
Automotive electronics:ntawm ib sab tes, kev ua haujlwm kub ntawm lub cav hluav taws xob tswj module, ignition module, fais fab module thiab ntau yam sensors yog siab heev; ntawm qhov tod tes, lub roj teeb lub zog ntawm lub tsheb tshiab lub zog yog loj, thiab cov tsoos cua txias thiab dej txias tsis txaus los tiv thaiv cov cua kub loj heev. Muaj qhov xav tau ceev thiab tus kheej rau cov khoom siv thermal interface.
Tsis tas li ntawd, cov cuab yeej siv hauv aviation, aerospace, tub rog, thiab lwm yam kev lag luam feem ntau yuav tsum tau ua haujlwm nyob rau hauv ib puag ncig hnyav xws li cov zaus, siab voltage, siab zog, thiab huab cua kub, thiab yuav tsum muaj kev ntseeg siab, ua haujlwm ntev ntev, thiab tsis tshua muaj siab. siab kev ua tau zoo xav tau rau cov ntaub ntawv kub dissipation.
Raws li BCC cov ntaub ntawv tshawb fawb, lub ntiaj teb kev lag luam loj ntawm cov khoom siv thermal interface tau nce los ntawm 716 lab nyiaj hauv 2014 txog 937 lab nyiaj hauv 2018, nrog kev loj hlob txhua xyoo ntawm 7.4%. Nws cia siab tias kev lag luam loj yuav ncav cuag 1.08 billion las hauv 2021. Ntawm lawv, thaj av Asia Pacific yuav tshaj 812 lab US las, Europe kwv yees li 113 lab US dollars, North America kwv yees li 101 lab US dollars, thiab lwm thaj tsam kwv yees li 54 lab. US nyiaj.
Thermal nrog cov pa hluav taws xob polymer raws li qhov zoo, tab sis yooj yim cov khoom siv hluav taws xob cov cua sov raws li cov cua sov raws li cov khoom siv hluav taws xob tsawg yog qhov tsawg. Cov ntaub ntawv inorganic nano xws li txhuas oxide, aluminium nitride, silicon carbide, Boron nitride thiab carbon nanotubes tuaj yeem txhim kho cov thermal conductivity ntawm cov ntaub ntawv polymer, tab sis inorganic fillers yuav ua rau cov ntaub ntawv polymer nkig thiab tawv. Tam sim no, tsis muaj kev daws teeb meem zoo rau qhov teeb meem no, thiab kev lag luam thoob ntiaj teb thiab kev lag luam hauv tsev yog nyob ntawm tib txoj kev.
Cov khoom siv thermal zoo tshaj plaws yuav tsum muaj cov yam ntxwv hauv qab no: siab thermal conductivity, siab yooj, nto wettability, zoo viscosity, siab siab rhiab heev, zoo thermal thiab txias voj voog stability, reusable, thiab lwm yam. Yog li ntawd, cov teeb meem ntxiv yuav tsum tau hais txog:
Ua ntej, hauv kev tsim cov khoom siv polymer raws li kev sib xyaw ua ke, kev tsim kho kom zoo dua yog xav tau los txhim kho thermal conductivity thaum ua kom cov khoom siv dag zog;
Thib ob, nyob rau hauv cov nqe lus ntawm kev npaj cov ntaub ntawv thiab kev ua, nws yog ib qho tsim nyog los txhim kho kev sib txuas ntawm kev sib txuas ntawm cov muab tub lim, cov khoom siv ntxiv, thiab cov matrix kom tau txais cov khoom zoo sib xws;
Thib peb, nyob rau hauv cov nqe lus ntawm kev tshawb fawb theoretical yooj yim, nws yog ib qho tsim nyog yuav tsum tau nkag siab ntxiv txog ntau qhov kev ntsuas phonon thaum tshav kub kub, cov khoom siv hluav taws xob, phonon electron coupling mechanism, complex electron thiab phonon thauj mechanism ntawm lub interface, thiab lwm yam. tsim cov khoom siv thermal interface.
