Iimodyuli zokupholisa ze-Thermoelectric Usetyenziso

Iimodyuli zokupholisa ze-Thermoelectric izicelo

Undoqo wemveliso yesicelo sokupholisa i-thermoelectric yimodyuli yokupholisa i-thermoelectric. Ngokweempawu, ubuthathaka kunye noluhlu lwesicelo se-thermoelectric stack, ezi ngxaki zilandelayo kufuneka zimiselwe xa ukhetha isitaki:

1. Ukumisela imeko yokusebenza kwezinto zokupholisa i-thermoelectric. Ngokwesalathiso kunye nobukhulu bomsebenzi wangoku, unokumisela ukupholisa, ukufudumeza kunye nokusebenza rhoqo kweqondo lokushisa kwe-reactor, nangona eyona nto isetyenziswa ngokuqhelekileyo yindlela yokupholisa, kodwa akufanele ingayihoyi ukufudumeza kwayo kunye nokusebenza rhoqo kweqondo lokushisa.

I-2, Misela ubushushu bokwenene besiphelo esishushu xa upholisa. Ngenxa yokuba i-reactor sisixhobo somahluko weqondo lobushushu, ukufezekisa eyona mpembelelo ilungileyo yokupholisa, i-reactor kufuneka ifakwe kwirediyetha elungileyo, ngokweemeko ezilungileyo okanye ezimbi zokuchitha ubushushu, misela ubushushu bokwenyani bokuphela kwe-thermal ye-reactor xa upholisa, kufuneka kuqatshelwe ukuba ngenxa yempembelelo yeqondo lobushushu, ubushushu bokwenyani bokuphela kwe-thermal ye-reactor buhlala bungaphezulu kweqondo le-radiator, ngokuqhelekileyo iqondo lokushisa elingaphantsi kwe-radiator lihlala liphezulu kunomlinganiselo we-radiator. izidanga ezilishumi. Ngokufanayo, ukongeza kwi-gradient yokutshatyalaliswa kobushushu ekupheleni kobushushu, kukho kwakhona i-gradient yeqondo lokushisa phakathi kwendawo epholileyo kunye nesiphelo esibandayo se-reactor.

3, Ukumisela indawo yokusebenza kunye nomoya we-reactor. Oku kubandakanya ukuba iimodyuli ze-TEC, iimodyuli zokupholisa i-thermoelectric ukuba zisebenze kwi-vacuum okanye kwi-atmosfera eqhelekileyo, i-nitrogen eyomileyo, umoya omileyo okanye ohambayo kunye nobushushu be-ambient, apho amanyathelo okufakelwa kwe-thermal (adiabatic) athathelwa ingqalelo kunye nomphumo wokuvuza kokushisa kunqunywe.

4. Ukumisela into esebenzayo yezinto ze-thermoelectric kunye nobukhulu bomthwalo we-thermal. Ukongeza kwimpembelelo yobushushu bokuphela kobushushu, ubuncinci beqondo lobushushu okanye umahluko omkhulu wobushushu onokuthi ufikelele kwi-TEC N, P izinto ezinokuthi zifezekiswe phantsi kweemeko ezimbini zokungabikho komthwalo kunye ne-adiabatic, enyanisweni, i-peltier N, P element ayinakuba yi-adiabatic ngokwenene, kodwa nayo kufuneka ibe nomthwalo oshushu, kungenjalo ayinantsingiselo.

5. Qinisekisa inqanaba lemodyuli ye-thermoelectric, imodyuli ye-TEC (i-peltier elements). Ukukhethwa koluhlu lwe-reactor kufuneka luhlangabezane neemfuno zomahluko wangempela weqondo lokushisa, oko kukuthi, umahluko weqondo lokushisa oqhelekileyo we-reactor kufuneka ube phezulu kunomahluko wokushisa ofunekayo, ngaphandle koko awukwazi ukuhlangabezana neemfuno, kodwa uchungechunge alukwazi ukuba lukhulu, kuba ixabiso le-reactor liphuculwe kakhulu ngokunyuka koluhlu.

6. Iinkcukacha zezinto ze-thermoelectric N,P. Emva koluhlu lwesixhobo se-peltier esikhethiweyo se-N, P element, iinkcukacha zezinto ze-peltier N,P zinokukhethwa, ngakumbi ukusebenza kwangoku kwezinto ezipholileyo ze-peltier N,P. Ngenxa yokuba kukho iintlobo ezininzi ze-reactors ezinokuhlangabezana nomahluko wobushushu kunye nemveliso ebandayo ngaxeshanye, kodwa ngenxa yeemeko ezahlukeneyo zokusebenza, i-reactor eneyona mini incinci yokusebenza idla ngokukhethwa, kuba iindleko zamandla ezixhasayo zincinci ngeli xesha, kodwa amandla ewonke e-reactor ngumba wokugqiba, igalelo elifanayo lamandla okunciphisa ukusebenza ngoku kufuneka linyuse i-voltage (0.1v ngeperi ye-tothm nganye)

7. Qinisekisa inani lezinto ze-N,P. Oku kusekelwe kumandla okupholisa iyonke ye-reactor ukuhlangabezana neemfuno zomahluko weqondo lobushushu, kufuneka iqinisekise ukuba isixa somthamo wokupholisa we-reactor kwiqondo lobushushu bokusebenza likhulu kunomthamo opheleleyo womthwalo we-thermal wento esebenzayo, ngaphandle koko ayikwazi ukuhlangabezana neemfuno. I-inertia ye-thermal ye-stack incinci kakhulu, akukho ngaphezu komzuzu omnye phantsi komthwalo, kodwa ngenxa ye-inertia yomthwalo (ikakhulukazi ngenxa yomthamo wokushisa womthwalo), isantya esisebenzayo sokufikelela kwiqondo lobushushu elimiselweyo likhulu kakhulu kunomzuzu omnye, kwaye ixesha elide kangangeeyure eziliqela. Ukuba iimfuno zesantya sokusebenza zinkulu, inani leemfumba liya kuba likhulu, amandla ewonke omthwalo we-thermal aqulunqwe ngumthamo obushushu opheleleyo kunye nokuvuza kobushushu (ubushushu obuphantsi, ngakumbi ukuvuza kobushushu).

Le miba isixhenxe ingentla yimigaqo jikelele ekufuneka iqwalaselwe xa ukhetha imodyuli ye-thermoelectric i-N, i-P peltier element, ngokutsho apho umsebenzisi wokuqala kufuneka aqale akhethe iimodyuli zokupholisa zombane we-thermoelectric, i-peltier cooler, imodyuli ye-TEC ngokweemfuno.

(1)Qinisekisa ukusetyenziswa kobushushu be-ambient Th ℃

(2) Ubushushu obuphantsi Tc ℃ bufikelelwe sisithuba esipholileyo okanye into

(3) Umthwalo we-thermal owaziwayo Q (amandla e-thermal Qp, ukuvuza kobushushu Qt) W

Ukunikezelwa kwe-Th, Tc kunye ne-Q, izinto ezifunekayo ze-Thermoelectric cooler N,P kunye nenani lezinto ze-TEC N,P zinokuqikelelwa ngokophawu lwemodyuli yokupholisa yombane we-thermoelectric, i-peltier cooler, iimodyuli zeTEC.
