Impembelelo ye-Thermoelectric yenzwa

Izinto zeSemiconductor zinamandla aphezulu e-thermoelectric kwaye zinokusetyenziswa ngempumelelo ukwenza iifriji ezincinci ze-thermoelectric. Umzobo we-1 ubonisa into yefriji ye-thermocouple eyenziwe yi-n-type semiconductor kunye ne-p-type semiconductor. I-semiconductor yohlobo lwe-N kunye ne-P-type semiconductor idibaniswe kwi-loop ngamacwecwe obhedu kunye neengcingo zethusi, kwaye iiplate zethusi kunye neengcingo zobhedu zidlala indima yomqhubi kuphela. Ngeli xesha, umfowunelwa omnye uba shushu kwaye omnye umfowunelwa uyabanda. Ukuba isalathiso sangoku siguqulwe, isenzo esibandayo kunye nesishushu kwi-node siyahambelana.

Imveliso yefriji ye-thermoelectric incinci kakhulu, ngoko ayifanelekanga ukusetyenziswa kwezinto ezinkulu kunye nezinkulu. Nangona kunjalo, ngenxa yokuguquguquka okunamandla, ukulula kunye nokulula, ifanelekile kakhulu kwintsimi yefriji encinci okanye iindawo ezibandayo ezineemfuno ezizodwa.

Isiseko sethiyori yefriji ye-thermoelectric yimpembelelo ye-thermoelectric yokuqina. Xa kungekho mhlaba wamagnetic wangaphandle, uquka iziphumo ezihlanu, ezizezi ukushisa ukushisa, ukulahleka kobushushu beJoule, umphumo we-Seebeck, umphumo wePeltire kunye ne-Thomson effect.

Ii-air conditioners kunye neefriji eziqhelekileyo zisebenzisa i-fluoride chloride njengefriji, ebangela ukuba i-ozone layer itshatyalaliswe. Iifriji ezingenafriji (ii-air conditioners) ke ziyinto ebalulekileyo ekukhuseleni indalo. Ukusebenzisa i-thermoelectric effect ye-semiconductors, ifriji engenafriji ingenziwa.

Le ndlela yokuvelisa amandla iguqula ngokuthe ngqo amandla e-thermal kumandla ombane, kwaye ukusebenza kwayo kokuguqulwa kulinganiselwe yiCarnotefficiency, umthetho wesibini we-thermodynamics. Kwangoko ngo-1822, uXibe wayifumanisa, ngoko ke isiphumo se-thermoelectric ikwabizwa ngokuba yiSeebeckeffect.

Ayihambelani kuphela nobushushu beendlela ezimbini zokudibanisa, kodwa kunye neempawu zabaqhubi abasetyenzisiweyo. Inzuzo yale ndlela yokuvelisa amandla kukuba ayinazo iindawo zomatshini ezijikelezayo kwaye ayiyi kunxitywa, ngoko ingasetyenziselwa ixesha elide. Nangona kunjalo, ukufezekisa ukusebenza kakuhle okuphezulu, umthombo wobushushu onobushushu obuphezulu uyafuneka, kwaye ngamanye amaxesha iileyiti ezininzi zezinto zombane we-thermoelectric ziyaphoswa okanye zibekwe ngokwenqanaba ukufikelela ukusebenza okuphezulu.
