Umphumela we-Thermoelectric wenzwa

Izinto zokwakha ze-semiconductor zinamandla aphezulu we-thermoelectric futhi zingasetshenziswa ngempumelelo ukwenza iziqandisi ezincane ze-thermoelectric.Umdwebo 1 ubonisa isici sesiqandisi se-thermocouple esakhiwe i-semiconductor yohlobo lwe-n kanye ne-semiconductor yohlobo lwe-p.I-semiconductor yohlobo lwe-N kanye ne-semiconductor yohlobo lwe-P ixhunywe ku-loop ngamapuleti ethusi nezintambo zethusi, futhi amapuleti ethusi nezintambo zethusi zidlala indima yokuqhuba kuphela.Kuleli qophelo, oyedwa othintana naye uyashisa futhi oyedwa othintana naye uyabanda.Uma isiqondiso samanje sihlehliswa, isenzo esibandayo nesishisayo ku-node siyahambisana.

Okukhiphayo kwesiqandisi se-thermoelectric ngokuvamile kuncane kakhulu, ngakho-ke akufanelekile ukusetshenziswa okukhulu nokukhulu.Kodwa-ke, ngenxa yokuguquguquka okuqinile, ukulula nokulula, ifaneleka kakhulu insimu yefriji encane noma izindawo ezibandayo ezinezidingo ezikhethekile.

Isisekelo sethiyori sesiqandisi se-thermoelectric umphumela we-thermoelectric wokuqinile.Uma ingekho inkambu kazibuthe yangaphandle, ihlanganisa imiphumela emihlanu, okungukuthi ukuqhutshwa kokushisa, ukulahlekelwa ukushisa kwe-Joule, umphumela we-Seebeck, umphumela we-Peltire kanye nomphumela we-Thomson.

Ama-air conditioner neziqandisi ezivamile zisebenzisa i-fluoride chloride njengesiqandisi, esibangela ukuba ungqimba lwe-ozone lubhujiswe.Ngakho-ke iziqandisi ezingenamakhaza (ama-air conditioner) ziyisici esibalulekile ekuvikelweni kwemvelo.Ngokusebenzisa umphumela we-thermoelectric wama-semiconductors, isiqandisi esingenasiqandisi singenziwa.

Le ndlela yokukhiqiza amandla iguqula ngokuqondile amandla ashisayo abe amandla kagesi, futhi ukusebenza kahle kwawo kokuguqulwa kukhawulelwe yi-Carnotefficiency, umthetho wesibili we-thermodynamics.Emuva ngo-1822, u-Xibe wayithola, ngakho umphumela we-thermoelectric ubizwa nangokuthi i-Seebeckeffect.

Akuhlobene kuphela nokushisa kwezinhlanganisela ezimbili, kodwa futhi nezakhiwo zama-conductor asetshenzisiwe.Inzuzo yale ndlela yokukhiqiza amandla ukuthi ayinazo izingxenye zemishini ezijikelezayo futhi ngeke igqoke, ngakho ingasetshenziswa isikhathi eside.Kodwa-ke, ukuze kuzuzwe ukusebenza kahle okuphezulu, umthombo wokushisa onezinga lokushisa eliphezulu uyadingeka, futhi ngezinye izikhathi izingqimba ezimbalwa zezinto ezisebenza ngogesi ezishisayo ziyancibilika noma zibekwe esiteji ukuze kuzuzwe ukusebenza kahle okuphezulu.
