Thermoelectric cov nyhuv ntawm sensor

Cov ntaub ntawv semiconductor muaj cov peev xwm siab thermoelectric muaj peev xwm thiab tuaj yeem ua tiav los ua kom ua rau cov tub yees thermoelectric me me. Daim duab 1 qhia txog cov tub yees thermocouple ua ke ntawm ib qho n-hom sliconductor thiab P-hom semiconductor. N-hom semiconductor thiab P-hom semiconductor tau txuas rau hauv lub voj los ntawm tooj liab thiab cov xov tooj liab tsuas yog ua lub luag haujlwm. Txij ntawm no, ib qho kev sib cuag tau kub thiab ib qho sib tiv tauj ua txias. Yog tias cov kev taw qhia tam sim no thim rov qab, tus mob khaub thuas thiab kub ntawm cov ntawm yog reciprocal.

Cov zis ntawm thermoelectric tub yees feem ntau yog me me, yog li nws tsis haum rau loj-teev thiab loj-teev siv. Txawm li cas los xij, vim hais tias ntawm nws muaj zog hloov, yooj yim thiab yooj yim, nws yog qhov haum rau micro-tub yees teb lossis chaw txias nrog cov cai tshwj xeeb.

Theoretical hauv paus ntawm thermoelectric tub yees yog cov nyhuv thermoelectric ntawm cov khoom. Thaum tsis muaj ib qho chaw sib nqus sab nraud, nws suav nrog tsib qhov teebmeem, joule cua sov, cov nyhuv cua sov, peltireks thiab Thomson nyhuv.

Cov tshuab cua txias thiab cov tub yees siv cov tshuaj fluoride ua tub yees, uas ua rau txheej ozone kom raug rhuav tshem. Tub yees txias-dawb (cua txias) yog li ntawd qhov tseem ceeb tshaj plaws hauv kev tiv thaiv ib puag ncig. Kev siv cov nyhuv thermoelectric ntawm semiconductors, lub tub yees txias txias ua tau.

Txoj kev muaj hwj chim no ncaj qha hloov kho hluav taws xob rau hauv hluav taws xob hauv lub zog hluav taws xob, thiab nws qhov kev hloov pauv hloov dua siab tshiab, ntawm txoj cai thib ob ntawm thermodynamics. Thaum ntxov li 1822, xib pom nws, yog li cov nyhuv thermielectric tseem hu ua ShawBeckeDect.

Nws tsis yog tsuas yog hais txog qhov ntsuas kub ntawm ob lub junctions, tab sis kuj rau cov khoom ntawm cov neeg saib xyuas. Qhov zoo dua ntawm txoj kev siv fais fab no yog tias nws tsis muaj kev sib hloov tshuab thiab yuav tsis hnav, yog li nws tuaj yeem siv rau lub sijhawm ntev. Txawm li cas los xij, kom ua tiav cov txiaj ntsig siab, ib qho kev kub kub uas xav tau, thiab qee zaum cov txheej txheem kub ntawm thermade lossis staged kom ua tiav kev ua tiav.
