Selelekela sa Mojule oa ho pholisa Thermoelectric
Theknoloji ea thermoelectric ke mokhoa o sebetsang oa tsamaiso ea mocheso o thehiloeng ho phello ea Peltier. E ile ea sibolloa ke JCA Peltier ka 1834, ketsahalo ena e kenyelletsa ho futhumatsa kapa ho pholisa ha mateano a lisebelisoa tse peli tsa thermoelectric (bismuth le telluride) ka ho feta hona joale mateanong. Nakong ea ts'ebetso, motlakase o tobileng o phalla ka har'a mochine oa TEC o etsang hore mocheso o fetisetsoe ho tloha ka lehlakoreng le leng ho ea ho le leng. Ho theha lehlakore le batang le le chesang. Haeba tataiso ea hona joale e khutlisetsoa morao, mahlakore a batang le a chesang a fetoha. Matla a eona a ho pholisa le ona a ka fetoloa ka ho fetola hajoale ts'ebetso ea ona. Setsi se pholileng sa sethala se le seng (setšoantšo sa 1) se na le lipoleiti tse peli tsa ceramic tse nang le p le mofuta oa n-mofuta oa semiconductor (bismuth,telluride) pakeng tsa lipoleiti tsa ceramic. Likarolo tsa thepa ea semiconductor li hokahantsoe ka motlakase ka tatellano le ka thermally ka ho bapa.
Thermoelectric cooling module, Peltier device, li-module tsa TEC li ka nkoa e le mofuta oa pompo ea matla a mocheso oa boemo bo tiileng, 'me ka lebaka la boima ba eona ba sebele, boholo le sekhahla sa karabelo, e loketse haholo ho sebelisoa e le karolo ea mekhoa ea ho futhumatsa e hahiloeng (ka lebaka la moeli oa sebaka). Ka melemo e kang ts'ebetso e khutsitseng, bopaki ba ho senya, ho hanyetsa ts'oaetso, bophelo bo bolelele bo sebetsang le tlhokomelo e bonolo, mochine oa sejoale-joale oa thermoelectric cooling module, sesebelisoa sa peltier, li-module tsa TEC li na le ts'ebeliso e fapaneng libakeng tsa lisebelisoa tsa sesole, sefofane, sefofane, kalafo ea bongaka, thibelo ea seoa, lisebelisoa tsa liteko, lihlahisoa tsa bareki (metsi a pholileng, pholileng ea koloi, sehatsetsi se pholileng, mocheso oa veine, jj.
Kajeno, ka lebaka la boima ba eona bo tlase, boholo bo nyane kapa bokhoni le theko e tlase, pholiso ea thermoelectric e sebelisoa haholo ho tsa bongaka, lisebelisoa tsa meriana, lifofane, sefofane, sesole, lits'ebetso tsa spectrocopy, le lihlahisoa tsa khoebo (tse kang mochini oa metsi a chesang le a batang, lihatsetsi tse nkehang, carcooler joalo-joalo)

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/UI
Qh= Qc + IU
△Tmax= Th+ 273 + κ/σα² x [ 1-√2σα²/κx (Th+273) + 1]
Iboholo =κS/ Lαx [√2σα²/κx (Th+273) + 1-1]
Iεboholo =αS (Th- Tc) / L (√1+0.5σα²(546+ Th- Tc)/ κ-1)
