Thermal rwb thaiv tsev Elastic Rubber

Lub thermal rwb thaiv tsev elastic roj hmab siv silicon roj hmab substrate, boron nitride, aluminium oxide thiab lwm yam ceramic particles li muab tub lim, thiab thermal conductivity nyhuv yog zoo heev. Nyob rau tib lub sijhawm, cov thermal impedance yog me dua li ntawm lwm cov khoom siv thermal conductive. Nws yog mos, huv si, tsis muaj kuab paug thiab hluav taws xob, thiab muaj kev rwb thaiv tsev siab. Cov iav fiber reinforcement muab cov khoom siv zoo, tuaj yeem tiv thaiv kev sib tsoo, shear thiab tsim kua muag, thiab tuaj yeem nruab nrog thermal conductive siab-rhiab nplaum nplaum. Lub thermal conductivity ntawm thermal conductive roj hmab tsis yog tsuas yog cuam tshuam nrog lub thickness ntawm thermal conductive cov ntaub ntawv, tab sis kuj muaj feem xyuam rau cov cheeb tsam ntawm thermal conductive khoom. Vim muaj kev sib raug zoo ntawm cov khoom siv thermal conductive, feem ntau, cov ntaub ntawv thermal conductive kuj muaj feem xyuam rau lub siab. Thaum lub siab yog siab, lub thermal conductivity yuav muaj zog. Feem ntau, qhov siab ntawm cov khoom siv hluav taws xob yog 5-100psi, thiab qhov siab ntawm lub tshuab hluav taws xob feem ntau yuav tsis tshaj 250psi.
Alumina thermal conductive roj hmab: nrog zoo thermal conductivity thiab zoo nkauj tsos, nws yog dav siv rau tshav kub dissipation ntawm kev sib txuas lus thiab lwm yam khoom.
Boron nitride thermal conductive roj hmab: Nws muaj cov thermal conductivity zoo heev thiab tsim nyog rau cov cua kub dissipation ntawm cov khoom siv hluav taws xob siab. Raws li cov xwm txheej zoo ib yam, piv nrog cov khoom siv hluav taws xob zoo tib yam, nws tuaj yeem ua rau cov cuab yeej kub qis dua li 20 degree.
Kev ceev faj rau kev siv:
Cov ntaub ntawv thermal rwb thaiv tsev saum toj no yog ua los ntawm silicone roj hmab. Lub tshav kub dissipation nto yuav tsum du, huv si thiab tsis muaj burrs thaum siv kom tsis txhob punncturing daim ntawv roj hmab thiab ua puas lub rwb thaiv tsev. Qhov me me ntawm cov thermal tsis kam ntawm cov khoom siv hluav taws xob, lub sij hawm luv dua rau kev nkag mus rau qhov ruaj khov, thiab qhov kub ntawm qhov stabilization qis dua. Kev siv cov ntawv thermal rwb thaiv tsev tsis tas yuav tsum tau ntxiv los ntawm lwm cov ntaub ntawv.
