Lub thermal rwb thaiv tsev Performance index ntawm cov khoom siv thermal rwb thaiv tsev yog txiav txim siab los ntawm thermal conductivity ntawm cov khoom.Qhov me me ntawm thermal conductivity, qhov zoo ntawm thermal rwb thaiv tsev kev ua tau zoo.Feem ntau, cov khoom siv thermal conductivity tsawg dua 0.23W / (m·K) yog hu ua cov ntaub ntawv rwb thaiv tsev kub, thiab cov khoom siv thermal conductivity tsawg dua 0.14W / (m·K) yog hu ua thermal rwb thaiv tsev cov ntaub ntawv;Feem ntau cov thermal conductivity tsis ntau tshaj 0.05W / (m · K) cov ntaub ntawv hu ua high-efficiency rwb thaiv tsev cov ntaub ntawv.Cov ntaub ntawv siv rau cov rwb thaiv tsev tsim feem ntau yuav tsum tau ua kom qis dua, kev tsim kho qis dua, kev tsim kho kom yooj yim, thiab tus nqi tsim nyog ib puag ncig, thiab tus nqi tsim nyog ib puag ncig, thiab tus nqi tsim nyog ib puag ncig, thiab tus nqi tsim nyog ib puag ncig, thiab tus nqi tsim nyog.

Cov yam ntxwv cuam tshuam rau thermal conductivity ntawm thermal rwb thaiv tsev cov ntaub ntawv.

1. Qhov xwm ntawm cov khoom.Cov thermal conductivity ntawm cov hlau yog qhov loj tshaj plaws, ua raws li cov hlau tsis yog hlau.Cov kua yog me dua thiab cov pa roj tsawg tshaj plaws.

2. Pom pom qhov ntom ntom thiab qhov pore yam ntxwv.Cov ntaub ntawv uas tsis tshua pom tseeb muaj qhov thermal conductivity tsawg.Thaum lub porosity zoo ib yam, qhov pore loj dua, qhov thermal conductivity ntau dua.

3. Cov av noo.Tom qab cov khoom absorbs noo noo, thermal conductivity yuav nce.Lub thermal conductivity ntawm dej yog 0.5W / (m·K), uas yog 20 npaug loj dua cov thermal conductivity ntawm huab cua, uas yog 0.029W / (m·K).Lub thermal conductivity ntawm cov dej khov yog 2.33W / (m·K), uas ua rau cov thermal conductivity ntau dua ntawm cov khoom.

4. Kub.Qhov kub nce, thermal conductivity ntawm cov khoom nce, tab sis qhov kub tsis tseem ceeb thaum qhov kub ntawm 0-50 ℃.Tsuas yog rau cov khoom ntawm qhov kub thiab qhov tsis zoo, cov nyhuv ntawm qhov kub thiab txias yuav tsum tau txiav txim siab.

5. Thaum tshav kub kub kev taw qhia.Thaum cov cua sov ntws mus rau qhov sib npaug ntawm cov kev taw qhia fiber ntau, cov thermal rwb thaiv tsev ua haujlwm tsis muaj zog;Thaum cov cua sov ntws yog perpendicular mus rau cov kev taw qhia fiber ntau, cov thermal rwb thaiv tsev kev ua tau zoo ntawm cov khoom siv thermal rwb thaiv tsev yog qhov zoo tshaj plaws.
