Vim li cas thiaj nrhiav tau cov khoom siv thermally conductive uas tsis muaj thermal tsis kam?

Qhov chaw sab hauv ntawm cov khoom siv hluav taws xob tau raug kaw, thiab huab cua yog qhov tsis zoo ntawm cov khoom siv hluav taws xob, yog li cov cua sov tsis yooj yim rau dissipate sab nraud hauv cov khoom siv hluav taws xob, ua rau cov khoom siv hluav taws xob hauv cheeb tsam kub dhau, thiab kev laus ntawm cov ntaub ntawv ntawm qhov kub thiab txias yog nrawm. thiab qhov ua tsis tiav ntawm cov khoom siv hluav taws xob tau nce.Yog li ntawd, thermal dissipation yog yuav tsum tau.

Kev siv cov khoom siv hluav taws xob dissipation yog cov txheej txheem hluav taws xob loj.Cov cua sov los ntawm qhov chaw ntawm lub tshav kub yog coj mus rau hauv lub dab dej kub los ntawm kev sib cuag nrog cov khoom siv hluav taws xob, yog li txo qhov kub ntawm lub cuab yeej.Txawm li cas los xij, muaj qhov sib txawv ntawm cov khoom sib txuas thiab cov khoom siv hluav taws xob, thiab muaj huab cua nyob hauv qhov sib txawv, thiab thaum tshav kub kub ua haujlwm ntawm ob, qhov kev sib txuas ceev yuav raug txo los ntawm huab cua, yog li cuam tshuam rau cov cua kub dissipation.

Cov khoom siv thermal conductiveyog ib lub ntsiab lus dav dav rau cov ntaub ntawv uas tau coated ntawm cov khoom siv hluav taws xob thiab cov khoom siv hluav taws xob ua kom sov thiab txo qhov kev sib cuag thermal ntawm ob.Thermally conductive cov ntaub ntawv tuaj yeem sau qhov sib txawv ntawm qhov sib txawv thiab tshem tawm cov huab cua hauv qhov khoob, yog li txo qhov kev sib cuag thermal ntawm ob.Thermal conductivity yog ib qho parameter los ntsuas qhov thermal conductivity ntawm cov khoom.Kev xaiv cov khoom siv thermal conductivity tsis yog tsuas yog ua raws li thermal conductivity, tab sis kuj thermal kuj ntawm thermal conductivity cov ntaub ntawv.

Thermal tiv thaiv ntawm lubCov khoom siv thermal conductiveyuav cuam tshuam nws thermal conductivity.Rau cov khoom siv hluav taws xob uas muaj cov thermal ua haujlwm siab, yog tias muaj ntau qhov ntsuas hauv cov yeeb nkab dej, qhov ceev ntawm cov dej ntws mus rau hauv cov yeeb nkab dej yuav raug thaiv thiab cov dej ntws yuav raug txo.Yog li ntawd, thermal tsis kam ntawm cov khoom siv hluav taws xob yog qhov tseem ceeb heev.Xaiv cov khoom siv thermal tsis tshua muaj thermal conductivity.
