Daim ntawv thov
Bismuth qhia rau (BI2te3)Yog ib cov khoom siv thermoelecric paub rau nws muaj peev xwm hloov lub zog thermal rau hauv lub zog hluav taws xob. Nws yog feem ntau muaj ob hom: P-homBi0.5SB1.5te3thiab n-hom bi2te2.7se0.3. P-hom Bi0.5SB1.5te3 feem ntau yog muaj li ntawm kev ua haujlwm, antesterium, hos n-hom bi2te2.3 muaj bismuth, selenium thiab selenium. Ob hom Bismuth qhia yog muaj nyob hauv cov ntsiav tshuaj lossis hmoov av.
Cov kev siv ntawmBismuth qhiaP-hom Bi0.5SB1.580 thiab n-hom bi2te2.7se0.3 feem ntau yog nyob rau hauv thaj chaw ntawm thermoelectric hloov zog. Cov ntaub ntawv no feem ntau siv hauv cov khoom siv thermoelectric tsim los txhawm rau siv qhov sib txawv los tsim hluav taws xob. P-hom bi0.5sb1.5te3 thiab n-hom bi2te2.7 tau tuaj yeem sib xyaw ua ke cov tshuab rov qab, thiab cov tshuab hluav taws xob ua hluav taws xob. Lawv txoj kev ua tau zoo thiab ua tau zoo ua rau lawv haum rau ntau yam ntawm cov kev siv hluav taws xob.
Ob P-Hom Bi0.5SB1.580 thiab N-hom BI2TE2.7se0.3 Bismuth qhia rau cov ntawv thov hluav taws xob zoo heev. Cov ntaub ntawv no tuaj yeem siv los tsim cov tshuab thermoelectric, tseem hu ua peltier txias, uas tshem cov cua sov los ntawm cov hluav taws xob thiab kev ua siab zoo ua haujlwm kub. Ntxiv rau,Bismuth qhiaP- thiab n-hom khoom siv yog siv rau kev tswj thermal kev tswj hwm hauv cov khoom kho mob, tshuab hluav taws xob aeroser.
Hauv cov ntsiab lus xaus,Bismuth qhiaP-hom Bi0.5SB1.5te3 thiab n-hom bi2te2.7 yog cov khoom siv muaj txiaj ntsig nrog kev hloov pauv dav thiab cua txias. Lawv cov khoom siv thermoelectric ua rau lawv tseem ceeb ntawm ntau lub tshuab thiab cov tshuab, ua rau muaj kev nce qib ntawm lub zog ua haujlwm thiab muaj kev siv zog thev naus laus zis. Raws li thov rau lub zog txuas ntxiv mus txuas ntxiv mus ntxiv, kev siv ntawmBismuth qhiaCov ntaub ntawv yuav tsum nce ntxiv, kev tshawb fawb tsav ntxiv thiab kev loj hlob ntawm thaj chaw no.
