Isingeniso Semojuli yokupholisa ye-Thermoelectric
Ubuchwepheshe be-Thermoelectric buyindlela esebenzayo yokuphatha ukushisa okusekelwe kumphumela we-Peltier. Yatholwa ngu-JCA Peltier ngo-1834, lesi simo sihilela ukushisisa noma ukupholisa ukuhlangana kwezinto ezimbili ze-thermoelectric (i-bismuth ne-teluride) ngokudlula okwamanje endaweni yokuhlangana. Ngesikhathi sokusebenza, okwamanje okuqondile kugeleza kumojula ye-TEC okwenza ukushisa kudluliselwe ukusuka kolunye uhlangothi kuya kolunye. Ukudala uhlangothi olubandayo nolushisayo. Uma isiqondiso samanje siguqulwa, izinhlangothi ezibandayo nezishisayo ziyashintshwa. Amandla ayo okupholisa nawo angalungiswa ngokushintsha ukusebenza kwawo kwamanje. Indawo epholile yesiteji esisodwa (Umfanekiso. 1) iqukethe amapuleti e-ceramic amabili anomsebenzi we-semiconductor ongu-p no-n (bismuth,telluride) phakathi kwamapuleti e-ceramic. Izakhi zezinto ze-semiconductor zixhunywe ngogesi ochungechungeni futhi ngokwe-thermal ngokuhambisana.
Imojula yokupholisa ye-Thermoelectric, idivayisi ye-Peltier, amamojula e-TEC angabhekwa njengohlobo lwephampu yamandla ashisayo esesimweni esiqinile, futhi ngenxa yesisindo sayo sangempela, usayizi kanye nezinga lokusabela, ifaneleka kakhulu ukuthi isetshenziswe njengengxenye yezinhlelo zokupholisa ezakhelwe ngaphakathi (ngenxa yomkhawulo wesikhala). Ngezinzuzo ezinjengokusebenza okuthulile, ukuvikela ubufakazi, ukumelana nokushaqeka, impilo ende ewusizo nokugcinwa kalula, imojula yesimanje yokupholisa i-thermoelectric, idivayisi ye-peltier, amamojula e-TEC anohlelo olubanzi emkhakheni wemishini yezempi, ezondiza, indiza, ukwelashwa, ukuvimbela ubhubhane, izinto zokuhlola, imikhiqizo yabathengi (indawo epholile amanzi, isipholile semoto, isiqandisi esipholile sehhotela, isiqandisi esipholile, isiqandisi somuntu siqu sokulala, isiqandisi esincane sehhotela, isiqandisi sokulala njll).
Namuhla, ngenxa yesisindo sakho esiphansi, usayizi omncane noma umthamo kanye nezindleko eziphansi, ukupholisa ugesi we-thermoelectric kusetshenziswa kakhulu kwezokwelapha, izinto zemithi, izindiza, i-aerospace, amasosha, amasistimu we-spectrocopy, kanye nemikhiqizo yokuthengisa (efana nesikhiphi samanzi ashisayo nabandayo, iziqandisi eziphathwayo, i-carcooler nokunye)

Ukwethulwa kwamaFomula ohlelo lokusebenza kumojula ye-TEC
Qc= 2N[α(Tc+273)-LI²/2σS-κs/Lx(Th-Tc)]
△T= [ Iα(Tc+273)-LI/²2σS] / (κS/L + I α]
U = 2 N [ IL /σS +α(Th-Tc)]
e = Qc/UI
Qh= Qc + IU
△Tubuningi= Th+ 273 + κ/σα² x [1-√2σα²/κx (Th+273) + 1]
Iubuningi =κS/ Lαx [√2σα²/κx (Th+273) + 1-1]
Iεubuningi =ASA (Th-Tc) / L (√1+0.5σα²(546+ Th-Tc)/ κ-1)
