Chiyambi cha Module Yozizira ya Thermoelectric
Tekinoloje ya Thermoelectric ndi njira yogwira ntchito yoyendetsera kutentha kutengera mphamvu ya Peltier.Zinapezeka ndi JCA Peltier mu 1834, chodabwitsachi chimakhudza kutentha kapena kuziziritsa kwapakatikati kwa zida ziwiri za thermoelectric (bismuth ndi telluride) podutsa panopo pamphambano.Panthawi yogwira ntchito, magetsi olunjika akuyenda kudzera mu module ya TEC yomwe imapangitsa kuti kutentha kusamutsidwe kuchokera kumbali imodzi kupita ku imzake.Kupanga mbali yozizira ndi yotentha.Ngati mayendedwe apano asinthidwa, mbali zozizira ndi zotentha zimasinthidwa.Mphamvu yake yozizira imathanso kusinthidwa posintha momwe ikugwirira ntchito.Wozizira wamba wagawo limodzi (Chithunzi. 1) amakhala ndi mbale ziwiri zadothi zokhala ndi p ndi n-mtundu wa semiconductor (bismuth,telluride) pakati pa mbale za ceramic.Zinthu za semiconductor zimalumikizidwa ndimagetsi motsatizana komanso molingana ndi thermally.
Thermoelectric kuzirala gawo, chipangizo Peltier, zigawo TEC akhoza kuonedwa ngati mtundu wa olimba boma matenthedwe mpope mphamvu, ndipo chifukwa cha kulemera kwake kwenikweni, kukula ndi mlingo anachita, ndi abwino kwambiri ntchito ngati mbali ya inbuilt kuzirala. machitidwe (chifukwa cha kuchepa kwa malo).Ndi zabwino monga kugwira ntchito chete, kuphwanya umboni, kukana kugwedezeka, moyo wautali wothandiza komanso kukonza kosavuta, gawo lamakono lozizira la thermoelectric, chipangizo cha peltier, ma module a TEC ali ndi ntchito zosiyanasiyana pazida zankhondo, ndege, ndege, chithandizo chamankhwala, mliri. kupewa, zida zoyesera, zinthu za ogula (zozizira madzi, zoziziritsa kukhosi, firiji ya hotelo, zoziziritsa kukhosi, zoziziritsa kukhosi zamunthu, zoziziritsa kukhosi & kutentha zogona, ndi zina).
Masiku ano, chifukwa cha kulemera kwake kochepa, kakulidwe kakang'ono kapena mphamvu ndi mtengo wotsika, kuzirala kwa thermoelectric kumagwiritsidwa ntchito kwambiri pazachipatala, zipangizo zamagetsi, ndege, ndege, asilikali, machitidwe a spectrocopy, ndi malonda (monga choperekera madzi otentha ndi ozizira, mafiriji onyamula, carcooler ndi zina zotero)
| Parameters | |
| I | Kugwira Ntchito Panopa ku module ya TEC (mu Amps) |
| Imax | Kugwiritsa Ntchito Panopa komwe kumapangitsa kusiyana kwakukulu kwa kutentha △Tmax(mu Amps) |
| Qc | Kuchuluka kwa kutentha komwe kumatha kuyamwa pankhope yozizira ya TEC (mu Watts) |
| Qmax | Zolemba malire kuchuluka kwa kutentha kuti akhoza odzipereka pa ozizira mbali.Izi zimachitika pa I = Imaxndi pamene Delta T = 0. (mu Watts) |
| Totentha | Kutentha kwa nkhope yotentha pamene gawo la TEC likugwira ntchito (mu ° C) |
| Tozizira | Kutentha kwa nkhope yozizira pamene gawo la TEC likugwira ntchito (mu ° C) |
| △T | Kusiyana kwa kutentha pakati pa mbali yotentha (Th) ndi mbali yozizira (Tc).Delta T = Th-Tc(ku °C) |
| △Tmax | Kusiyana kwakukulu kwa kutentha kwa gawo la TEC kumatha kukwaniritsa pakati pa mbali yotentha (Th) ndi mbali yozizira (Tc).Izi zimachitika (Kuchuluka kozizira kwambiri) pa I = Imaxndi Qc= 0. (mu °C) |
| Umax | Mphamvu yamagetsi pa I = Imax(mu Volts) |
| ε | Kuzizira kwa module ya TEC (%) |
| α | Seebeck coefficient of thermoelectric material (V/°C) |
| σ | Mphamvu yamagetsi yamagetsi yamagetsi (1/cm·ohm) |
| κ | Thermo conductivity of thermoelectric material (W/CM·°C) |
| N | Chiwerengero cha thermoelectric element |
| Iεmax | Zomwe zimaphatikizidwa pomwe mbali yotentha ndi kutentha kwa mbali yakale ya gawo la TEC ndi mtengo wodziwika ndipo zimafunikira kuti muzitha kuchita bwino kwambiri (mu Amps) |
Kuyambitsa Mafomu Ogwiritsira Ntchito ku TEC module
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)]
ndi = Qc/UI
Qh= Qc + IU
△Tmax= Th+ 273 + κ/σα² x [1-√2σα²/κx (Th+273 + 1]
Imax =κS/ Lαx [√2σα²/κx (Th+273) + 1-1]
Iεmax =AAS (Th-Tc) / L (√1+0.5σα²(546+ Th-Tc)/k-1)
