Intshayelelo yemodyuli yokupholisa iThermoelectric

Itekhnoloji ye-Thermoelectric yindlela yokulawula ukushisa okusebenzayo ngokusekelwe kwimpembelelo yePeltier. Ifunyenwe ngu-JCA Peltier ngo-1834, le nto ibandakanya ukufudumeza okanye ukupholisa kwe-junction yezinto ezimbini ze-thermoelectric (i-bismuth kunye ne-teluride) ngokudlula okwangoku kwi-junction. Ngethuba lokusebenza, ukuhamba ngokuthe ngqo kwimodyuli ye-TEC kubangela ukuba ukushisa kudluliselwe ukusuka kwelinye icala ukuya kwelinye. Ukudala icala elibandayo nelishushu. Ukuba ulwalathiso lwangoku luguqulwa, amacala abandayo kunye ashushu atshintshiwe. Amandla ayo okupholisa nawo anokulungiswa ngokutshintsha ukusebenza kwawo ngoku. Ukupholisa okuqhelekileyo kwenqanaba elinye (Umfanekiso. 1) uqulathe iipleyiti ezimbini zeseramikhi ezinemathiriyeli ye-p kunye nohlobo lwe-n-udidi lwesemiconductor (bismuth,telluride) phakathi kweepleyiti zeseramikhi. Izinto eziphathekayo ze-semiconductor zixhunyiwe ngombane kwi-series kunye ne-thermal ngokufana.

Imodyuli yokupholisa iThermoelectric, isixhobo sePeltier, iimodyuli zeTEC zinokuthathwa njengohlobo lwempompo yamandla obushushu obuqinileyo, kwaye ngenxa yobunzima bayo bokwenyani, ubungakanani kunye nesantya sokuphendula, ifanelekile kakhulu ukuba isetyenziswe njengenxalenye yeenkqubo zokupholisa ezakhelwe ngaphakathi (ngenxa yokunciphisa indawo). Ngezinto eziluncedo ezinjengokusebenza okuthe cwaka, ubungqina bokuqhekeza, ukuxhathisa ukothuka, ubomi obude kunye nokugcinwa lula, imodyuli yokupholisa ye-thermoelectric yanamhlanje, isixhobo se-peltier, iimodyuli zeTEC zinesicelo esibanzi kwimimandla yezixhobo zomkhosi, inqwelomoya, inqwelomoya, inqwelomoya, unyango, uthintelo lobhubhane, izixhobo zovavanyo, iimveliso zabathengi (indawo epholileyo yamanzi, i-cooler yemoto, ifriji epholileyo yehotele, ifriji epholileyo, ubushushu bomntu njl njl.

Namhlanje, ngenxa yobunzima bayo obuphantsi, ubungakanani obuncinci okanye umthamo kunye nexabiso eliphantsi, ukupholisa kwe-thermoelectric kusetyenziswa kakhulu kwezonyango, izixhobo zamayeza, inqwelomoya, i-aerospace, umkhosi, iinkqubo ze-spectrocopy, kunye neemveliso zorhwebo (ezinjengendawo yokukhupha amanzi ashushu nabandayo, iifriji eziphathwayo, i-carcooler njalo njalo)

 

Iiparamitha
I Ukusebenza kwangoku kwimodyuli yeTEC (kwiAmps)
Imax  Ukusebenza kwangoku okwenza owona mahluko aphezulu wobushushu △Tmax(kwiAmps)
Qc  Ubungakanani bobushushu obunokufunxwa kwicala elibandayo lobuso beTEC (ngeWatts)
Qmax  Ubuninzi bobushushu obunokufunxwa kwicala elibandayo. Oku kwenzeka ku-I = Imaxkwaye xa iDelta T = 0. (kwiWatts)
Tshushu  Iqondo lobushushu lobuso becala elishushu xa imodyuli yeTEC isebenza (nge °C)
Tkubanda  Ubushushu becala elibandayo lobuso xa imodyuli yeTEC isebenza (nge °C)
△T  Umahluko kubushushu phakathi kwecala elishushu (Th) kunye necala elibandayo (Tc). I-Delta T = Th-Tc(kwi °C)
△Tmax  Owona mahluko mkhulu kwiqondo lobushushu imodyuli yeTEC inokufikelela phakathi kwecala elishushu (Th) kunye necala elibandayo (Tc). Oku kwenzeka (Ubukhulu bomthamo wokupholisa) e-I = Imaxkunye Qc= 0. (kwi °C)
Umax Ubonelelo lombane kwi-I = Imax(kwiiVolts)
ε Ukupholisa kwemodyuli ye-TEC ngokufanelekileyo (%)
α I-Seebeck coefficient of thermoelectric material (V/°C)
σ Umlinganiso wombane wemathiriyeli ye-thermoelectric (1/cm·ohm)
κ Thermo conductivity of thermoelectric imathiriyeli (W/CM · °C)
N Inani le-thermoelectric element
Iεmax Okwangoku incamathele xa icala elishushu kunye necala elidala lobushushu bemodyuli yeTEC lixabiso elichaziweyo kwaye ibifuna ukufumana Ubuninzi bokusebenza kakuhle (kwiAmps)
 

Ukwaziswa kweeFomula zesicelo kwimodyuli yeTEC

 

Qc= 2N[α(Tc+273)-LI²/2σS-ks/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]

Iubuninzi =κS/ Lαx [√2σα²/κx (Th+273) + 1-1]

Iεubuninzi =aas (Th-Tc) / L (√1+0.5σα²(546+ Th-Tc)/ κ-1)
