Yuav ua li cas yog pob zeb diamond ua cua sov?

Nrog kev txhim kho cov cuab yeej thev naus laus zis, ntau dua thiab cov hluav taws xob hluav taws xob ntau dua thiab cov neeg siv hluav taws xob tau nce ntxiv, thiab cov neeg siv hluav taws xob ntau dua, thiab cov pa hluav taws kub tsis sib haum xeeb yuav tsis muaj teeb meem cua sov dissipate tshav kub thiab txias cov khoom tau dhau los ua thawj cov kev sib tw {}}

 

• Yog li yuav ua li cas xaiv cov ntaub ntawv hauv teb thermal conductivity thiab cua sov dissipation?

Tam sim no, cov nrov nrov tshav kub dissmation cov tshuaj feem ntau suav nrog cov ntaub ntawv tawg, thiab hom kev sib cav kub thiab muaj cov cua sov {}} tib lub sijhawm, Lawv kuj tsis tau raws li cov neeg yuav tsum tau ua zoo xws li cov ntaub ntawv nthuav dav, thiab lub teeb ci tshiab {} txig {. Lawv muaj cov khoom siv thermal yog chav kawm muaj peev xwm ua kom pom tseeb cov tib neeg lub siab.

 

• Cov kev ua haujlwm zoo tshaj plaws thermal thiab cua sov dissipation ntawm pob zeb diamond

Ntsib nrog ntau qhov kev txwv ntawm cov khoom ntim ntim ib txwm muaj, yog cov khoom siv hluav taws xob ntau tshaj, muaj ntau yam ntawm cov pob zeb diamond, muaj ntau yam pob zeb diamond, xws li hom Ia, IB, Iia, IIB, thiab lwm yam kev nqus cov khoom nqus dej I6 4} ntawm pob zeb diamond tej zaum yuav tsis yog tib lub. thermal conductivity ntawm tib hom kub, raws li qhia hauv qab no:

The thermal conductivity of diamond is not fixed and has a range of variation. The main materials used as diamond heat sinks are Type IIa single crystal diamond and polycrystalline diamond with required thermal conductivity, with a thermal expansion coefficient of about 0.8 × 10-6/K and insulation at room temperature.

 

• Lub hauv paus ntsiab lus ntawm pob zeb diamond thermal conductivity

Pob zeb diamond muaj cov qauv siv leadic crystal, qhov chaw uas muaj cov hluav taws xob sib txuas lus nrog plaub yam khoom siv dawb, pob zeb diamond tsis sib xws yog cuam tshuam nrog kev siv hluav taws xob siab conductivity {{4 4}} tsis zoo li cov pa hluav taws xob uas siv hluav taws xob ntawm cov pa hluav taws xob (i}} Phonons) {}.

 

Txoj kev ua tsis yog cov suab phonons yog txiav txim siab los ntawm kev sib tsoo ntawm cov khib nyiab, nrog rau cov suab paj nruag, yog li txwv tsis pub muaj suab paj nruag ntawm cov suab nkauj thiab txo thermal conductivity .

 

Thaum cov khoom siv tau yooj yim dua, tus qauv yooj yim dua, thiab kev cuam tshuam nrog kev sib cav sib ceg, thiab cov kev hloov pauv kub sai dua, thiab cov kev sib hloov kub dua ntawm cov suab nrov ntawm cov suab phonons lossis Lub tshuab hluav taws xob . Cov lej muaj pes tsawg leeg yog ib qho uas muaj pob zeb diamond ia, thiab IIA, IIA

 

Yav dhau los, thaum yuav cov pob zeb diamond, qee tus neeg yuav yaim lawv nrog cov nplaig ntawm lawv tus nplaig} Yog tias lawv muaj lub hau ntawm lawv tus nplaig txias, nws yog pob zeb diamond tiag tiag; Yog tias nws sov, nws tsuas yog iav . Tus lej ntawm lub gemal conductivity yog ntau dua li qhov sib txawv ntawm ob .

 

Ntxiv rau, pob zeb diamond kuj muaj cov yam ntxwv ntawm kev ua kom muaj zog, uas tsis tshua muaj zog rau kev siv hluav taws xob, thiab tsis muaj peev xwm ua tau zoo rau hauv tshav kub kub dissipation .
