Umphumela we-thermoelectric we-sensor

Izinto ze-semicondector zinamandla aphezulu we-thermoelectric futhi angasetshenziswa ngempumelelo ukwenza iziqahishi ezincane ze-thermoelectric. Fig. 1 ikhombisa i-thermocouple refigeration element ehlanganiswe ne-semiconductor ye-n-semiconductor kanye ne-semiconductor ye-p-tex. I-semiconductor ye-n-semiconductor kanye ne-semiconductor ye-P-Tycond ixhumeke kwi-loop ngamapuleti ethusi kanye nezintambo zethusi, kanye namapuleti ethusi kanye nezintambo zethusi kuphela abadlala indima esebenza kuphela. Ngalesi sikhathi, oxhumana naye uba oshisayo futhi oxhumana naye munye ubanda. Uma ukuqondiswa kwamanje kubuyiselwa emuva, isenzo esibandayo nesishisayo endaweni yokuphindisela.

Ukukhishwa kwesiqandisi se-thermoelectric ngokuvamile kuncane kakhulu, ngakho-ke akulungele ukusetshenziswa okukhulu nokusetshenziswa okukhulu. Kodwa-ke, ngenxa yokuguquguquka okuqinile, okulula kanye nokusebenziseka kalula, ilungele kakhulu inkambu yefriji encane noma izindawo ezibandayo ezinezidingo ezikhethekile.

Isisekelo se-theorrical of thermoelectric wumphumela we-thermoelectric oqinile. Lapho kungekho nkabunatiki yangaphandle, ifaka imiphumela emihlanu, okungukuthi ukushiswa kokushisa, ukulahleka kokushisa kwe-jeule, umphumela we-beebeck, umphumela we-pellite kanye nomphumela we-thomson.

Ama-generali air conditioners kanye neziqandisini zisebenzisa i-fluoride chloride njenge-esiqandisini, esenza ungqimba lwe-ozone lubhujiswe. Iziqandisi ezifriga-zamahhala (izicubu zomoya) ngakho-ke ziyisici esibalulekile ekuvikelweni kwemvelo. Usebenzisa umphumela we-thermoelectric of semiconductors, isiqandisi samahhala esiqandisi esiqandisiwe singenziwa.

Le ndlela yesizukulwane samandla iguqula ngokuqondile amandla afudumele ibe amandla kagesi, futhi ukusebenza kwayo kokuguqulwa kukhawulelwe yi-CarloctocFinecín, umthetho wesibili we-thermodynamics. Ngo-1822, i-XIBE yathola lokho, ngakho-ke umphumela we-thermoelectric ubizwa nangokuthi i-betebeckeffect.

Akuhlobene kuphela nokushisa kwezindlela ezimbili, kepha futhi nasezakhiweni zabaqhubi ezisetshenzisiwe. Inzuzo yale ndlela yokuphehla amandla ukuthi ayinazo izingxenye ezijikelezayo zemishini futhi ngeke igqokwe, ngakho-ke ingasetshenziswa isikhathi eside. Kodwa-ke, ukufezekisa ukusebenza okuphezulu, umthombo wokushisa onamazinga okushisa aphezulu uyadingeka, futhi kwesinye isikhathi izingqimba eziningana zezinto ze-thermoelectric zingama-cascoelectric noma ahlelekile ukufezekisa ukusebenza kahle.
