Isingeniso Semodyuli Yokupholisa Ye-Thermoelectric
Ubuchwepheshe be-Thermoelectric buyindlela yokuphatha ukushisa esebenzayo esekelwe kumphumela we-Peltier. Yatholakala yi-JCA Peltier ngo-1834, lesi simo sihilela ukushisa noma ukupholisa indawo yokuhlangana kwezinto ezimbili ze-thermoelectric (i-bismuth ne-telluride) ngokudlulisa ugesi endaweni yokuhlangana. Ngesikhathi sokusebenza, ugesi oqondile ugeleza nge-module ye-TEC okwenza ukushisa kudluliselwe kusuka kolunye uhlangothi kuye kolunye. Ukudala uhlangothi olubandayo nolushisayo. Uma isiqondiso sogesi siguqulwa, izinhlangothi ezibandayo nezishisayo ziyashintshwa. Amandla ayo okupholisa angalungiswa ngokushintsha ugesi wawo osebenzayo. I-cooler ejwayelekile yesigaba esisodwa (Isithombe 1) iqukethe amapuleti amabili e-ceramic ane-p kanye ne-n-type semiconductor material (bismuth,telluride) phakathi kwamapuleti e-ceramic. Izinto zezinto ze-semiconductor zixhunywe ngogesi ngokulandelana futhi zihambisana ngokushisa.
Imojula yokupholisa ye-thermoelectric, idivayisi ye-Peltier, amamojula e-TEC angabhekwa njengohlobo lwepompo yamandla okushisa eqinile, futhi ngenxa yesisindo sayo sangempela, usayizi kanye nesivinini sokusabela, ifaneleka kakhulu ukusetshenziswa njengengxenye yezinhlelo zokupholisa ezakhelwe ngaphakathi (ngenxa yokulinganiselwa kwesikhala). Ngezinzuzo ezifana nokusebenza okuthule, ukuvikela ukuphahlazeka, ukumelana nokushaqeka, impilo ende ewusizo kanye nokugcinwa okulula, imojula yokupholisa ye-thermoelectric yesimanje, idivayisi ye-peltier, amamojula e-TEC anohlelo olubanzi lokusetshenziswa emikhakheni yemishini yezempi, izindiza, izindiza, ukwelashwa kwezokwelapha, ukuvimbela ubhubhane, imishini yokuhlola, imikhiqizo yabathengi (i-water cooler, i-car cooler, i-hotel refrigerant, i-wine cooler, i-cooler encane yomuntu siqu, i-cool & heat sleep pad, njll.).
Namuhla, ngenxa yesisindo sayo esiphansi, usayizi omncane noma umthamo kanye nezindleko eziphansi, ukupholisa kwe-thermoelectric kusetshenziswa kabanzi kwezokwelapha, imishini yezokwelapha, izindiza, izindiza, ezempi, izinhlelo ze-spectrocopy, kanye nemikhiqizo yezentengiselwano (njenge-dispenser yamanzi ashisayo nabandayo, iziqandisi eziphathwayo, i-carcooler njalo njalo)

Ukwethulwa kwamafomula ohlelo lokusebenza kumojuli we-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)]
ε = Qc/I-UI
Qh= Qc + I-IU
△Tubuningi= Th+ 273 + κ/σα² x [1-√2σα²/κx (Th+273) + 1]
Iubuningi =κS/ Lax [√2σα²/κx (Th+273) + 1-1]
Iεubuningi =ασS (Th- Tc) / L (√1+0.5σα²(546+ Th- Tc)/ κ-1)
