Nhanganyaya yeThermoelectric cooling module
Tekinoroji yeThermoelectric inzira inoshanda yekutonga kupisa yakavakirwa paPeltier effect. Yakawanikwa neJCA Peltier muna 1834, chiitiko ichi chinosanganisira kupisa kana kutonhora kwenzvimbo mbiri dzethermoelectric (bismuth netelluride) nekupfuura nepanoungana magetsi. Munguva yekushanda, direct current inoyerera nepakati peTEC module zvichiita kuti kupisa kutamiswe kubva kune rumwe rutivi kuenda kune rumwe. Kugadzira divi rinotonhora nerinopisa. Kana divi remagetsi rikadzoserwa shure, mativi anotonhora neanopisa anochinjwa. Simba rayo rekutonhora rinogonawo kugadziriswa nekushandura operating current yayo. Chinhu chinotonhorera chechikamu chimwe chete (Mufananidzo 1) chine maplate maviri eceramic ane p ne n-type semiconductor material (bismuth,telluride) pakati pemaplate eceramic. Zvinhu zve semiconductor material zvakabatana nemagetsi zvakatevedzana uye zvinoenderana nekupisa.
Module yekutonhodza yeThermoelectric, mudziyo wePeltier, mamodule eTEC anogona kutorwa semhando yepombi yesimba rekupisa yakasimba, uye nekuda kwehuremu hwayo chaihwo, saizi uye kumhanya kwekuita, yakakodzera kushandiswa sechikamu chemasisitimu ekutonhodza akavakwa mukati (nekuda kwekushomeka kwenzvimbo). Nezvakanakira zvakaita sekushanda kwakanyarara, kuputika, kuramba kuvhunduka, kushanda kwenguva refu uye kugadzirisa kuri nyore, module yemazuva ano yekutonhodza yethermoelectric, mudziyo wepeltier, mamodule eTEC ane mashandisirwo akasiyana-siyana muminda yemidziyo yemauto, ndege, ndege, kurapwa, kudzivirira denda, michina yekuedza, zvigadzirwa zvevatengi (mvura inotonhodza, mota inotonhodza, firiji yehotera, waini inotonhodza, cooler yekurara inotonhorera & kupisa, nezvimwewo).
Nhasi, nekuda kwehuremu hwayo hushoma, saizi diki kana kugona kwayo uye mutengo wakaderera, kutonhora kwethermoelectric kunoshandiswa zvakanyanya mumishonga, mishonga, ndege, ndege, mauto, masisitimu espectrocopy, uye zvigadzirwa zvemabhizinesi (zvakadai semuchina wemvura inopisa neinotonhora, mafiriji anotakurika, muchina wekutonhodza mota nezvimwewo)

Kusumwa kwemafomura ekushandisa kuTEC module
Qc= 2N[α(T)c+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= Mubvunzoc + IU
△Tzvakanyanya= Th+ 273 + κ/σα² x [ 1-√2σα²/κx (Th+273) + 1]
Ihuwandu =κS/ Lax [√2σα²/κx (Th+273) + 1-1]
Iεhuwandu =ασS (T)h- Tc) / L (√1+0.5σα²(546+ T)h- Tc)/ κ-1)
