Spherical Alumina: Nqi-zoo Thermal Conductive Powder Khoom

Nrog rau kev loj hlob tawg ntawm lub zog siv zog xws li 5G thiab lub zog tshiab, cov ntaub ntawv thermal conductivity yuav dhau los ua cov ntaub ntawv tseem ceeb.Raws li lub ntsiab muab tub lim,kheej kheej aluminayog suav tias yog tus nqi zoo tshaj plaws thermal hmoov muab tub lim hauv kev lag luam, thiab nws yuav tsum ua raws li kev loj hlob ntawm kev lag luam thermal conductivity thiab thiab qhov kev thov yuav tawg.

Peb feem ntau siv fillers yog hlau muab tub lim, cov ntaub ntawv carbon, thiab cov ntaub ntawv ceramic.Txawm hais tias hlau muab tub lim thiab cov ntaub ntawv carbon lawv tus kheej muaj cov thermal conductivity siab, uas tuaj yeem txhim kho cov thermal conductivity ntawm cov ntaub ntawv polymer, lawv muaj peev xwm ua kom puas lub rwb thaiv tsev ntawm cov ntaub ntawv nyob rau hauv siab load.Thiab cov ntaub ntawv carbon xws li graphene los yog carbon nanotubes tsis yooj yim rau disperse nyob rau hauv lub matrix, uas yog tsis conducive rau tsim ib tug zoo thermal conduction txoj kev.Piv nrog rau ob hom fillers, ceramic fillers tau nyiam ntau thiab ntau xim nyob rau hauv lub tshav pob ntawm kev npaj siab thermal conductivity composites vim lawv zoo heev tshav kub hloov zog thiab siab rwb thaiv tsev zog.Ntawm lawv,Al2O3 fillers tau dav siv thiab tshawb fawb vim lawv cov thermal conductivity, siab tiv taus, tsis tshua muaj dielectric poob, thiab kev ua haujlwm siab.Spherical fillers yog qhov zoo dua rau kev ua haujlwm thermal conduction ntawm thermally conductive fillers, yog li feem ntau siv thermally conductive muab tub lim nyob rau hauv kev ua lag luam feem ntau yog spherical alumina hmoov.

Vim tias nws cov thermal conductivity zoo thiab kev ua haujlwm zoo heev, spherical alumina hmoov yog cov thermal conductivity muab tub lim siv ntau nyob rau hauv kev lag luam tam sim no thermal interface cov ntaub ntawv thiab nyiaj rau cov feem ntau.Cov khoom siv hluav taws xob muaj xws li thermal gasket, thermal silicone roj, thermal sealing kua nplaum thiab thermal gel, thiab lwm yam. Lub davhlau ya nyob twg yog siv rau cov cua sov dissipation ntawm ntau yam khoom siv hluav taws xob sib txuas lus, lub zog tshiab lub tsheb roj teeb, cov khoom siv hluav taws xob, LED teeb, cov khoom siv hluav taws xob sab nraum zoov, transformers, thiab lwm yam, qhov kev thov rau spherical aluminium oxide hmoov rau thermal aluminium puag tooj liab clad phaj, thermal yas sealing khoom, thermal engineering plastics (xws li LED teeb ntxoov ntxoo, cov khoom siv hluav taws xob, cov khoom siv hluav taws xob), thermal txau txheej cov ntaub ntawv, tshwj xeeb ceramics, thiab cov khoom sib tsoo tshwj xeeb kuj tseem maj mam nce.
