Intshayelelo kwimodyuli yokupholisa i-thermoectric
Itekhnoloji ye-Thermoeletric yindlela esebenzayo yolawulo lwe-thermoal esebenzayo kwisiphumo se-pelier. Yafunyanwa nguJca petier ngo-1834, le nto ibandakanya ukufudumeza okanye ukupholisa i-cunction yezixhobo ezimbini ze-thermoelectoect (i-bismuth nakwi-bisther kunye ne-exor. Ngexesha lokusebenza, ukuhamba ngokungqalileyo ngemodyuli ye-TEC ebangela ubushushu buye kwelinye icala ukuya kwelinye. Ukwenza icala elibandayo nelishushu. Ukuba indlela yendlela yangoku ibuyisiwe, amacala abandayo atshintshiwe. Amandla ayo okupholisa anokuhlengahlengiswa ngokutshintsha okwangoku kwangoku. Inqanaba eliqhelekileyo eliyinqanaba. 1) Ineplate ezimbini ze-ceramic kunye ne-P kunye ne-N-CeeOndutor Izinto eziza kuba zizinto (i-bismuth, isixelele) phakathi kweepleyiti ze-cemaramic. Izinto ze-semiconductor kwezixhobo zixhunyiwe ngombane kwingcelele kunye nengqolo ngokuhambelana.
Imodyuli yokupholisa i-thermoectric, isixhobo se-Petlier, iimodyuli zeTec zinokuthathwa njengohlobo lwempompo yamandla e-thermal ye-thermal ye-thermal, kwaye ngenxa yobunzima bayo, ubungakanani kunye nenqanaba lokuphendula Iinkqubo (ngenxa yokuncitshiswa kwendawo). Ngezibonelelo ezifana nokusebenza cwaka, ukungqinelana, ukungcungcutheka kothusayo, ukulungiswa okumnandi, i-tertier yezixhobo, iimodyuli ze-Pecrier, i-Aec, i-Aec, i-Aecpace, iBibmic UKUTHENGA & Ubushushu bokulala i-PAD, njl. Njl.
Namhlanje, ngenxa yobunzima bayo obuphantsi, ubungakanani obuphantsi okanye ubungakanani beendleko eziphantsi, ukulingana kwe-thermoectric kusetyenziswa kakhulu kwizonyango, i-aerospacep, i-aerospace, i-aleds, iifriji zamanzi ezishushu, I-carcooler kwaye kunjalo)

| Iεmax | Iqhotyoshelwe ngoku xa icala elishushu kunye neqondo lokushisa elidala lemodyuli ye-TEC lixabiso elichaziweyo kwaye lifuna ukufumana impumelelo enobuchule (kwi-Ampps) |
Ukwaziswa kwefomula yesicelo kwimodyuli yeTec
Qc= 2n [α (tc+273) -Li²/ 2σS-κs / lx (th- tc)]
△ T = [iα (tc+273)-²2σs] / (κs / l + i α]
U = 2 n [il / σs + α (th- tc)]
= qc/ Ui
Qh= Qc + Iu
△ tmax= Th273 κ / σσσ² x [1-√2σασ / κX (Th+273) + 1]
Imax =I / lαx [√2σα / κX (th+273) + 1-1]
Iεmax =ασs (th- tc) / L (¶1 + 0.5σσ² (546+ th- tc)/ κ-1)
