Izinhlelo zokusebenza zamamojula wokupholisa we-Thermoelectric
Umnyombo womkhiqizo wesicelo sokupholisa se-thermoelectric yimojuli yokupholisa ye-thermoelectric. Ngokuya ngezici, ubuthakathaka nobubanzi bokusetshenziswa kwesitaki se-thermoelectric, izinkinga ezilandelayo kufanele zinqunywe lapho kukhethwa isitaki:
1. Thola isimo sokusebenza sezinto zokupholisa ze-thermoelectric. Ngokuya ngesiqondiso nobukhulu bokusebenza kwamanje, ungakwazi ukunquma ukupholisa, ukushisa kanye nokusebenza okuqhubekayo kwezinga lokushisa kwe-reactor, nakuba okuvame ukusetshenziswa kakhulu kuyindlela yokupholisa, kodwa akufanele ukushaye indiva ukushisa kwayo nokusebenza okuqhubekayo kokushisa.
2, Thola izinga lokushisa langempela lokuphela okushisayo lapho upholisa. Ngenxa yokuthi i-reactor iyidivayisi yomehluko wokushisa, ukuze kuzuzwe umphumela omuhle kakhulu wokupholisa, i-reactor kufanele ifakwe kurediyetha enhle, ngokuya ngezimo ezinhle noma ezimbi zokushisa ukushisa, inqume izinga lokushisa langempela lokuphela okushisayo kwe-reactor lapho ipholisa, kufanele kuqashelwe ukuthi ngenxa yethonya lokushisa kwe-gradient, izinga lokushisa langempela lokuphela kwe-thermal ye-reactor lihlala liphakeme kunamadigri ambalwa, ngokuvamile ngaphansi kwezinga lokushisa elingaphansi kwezingu-10. amadigri ayishumi. Ngokufanayo, ngaphezu kwe-gradient yokukhishwa kokushisa ekugcineni okushisayo, kukhona futhi i-gradient yezinga lokushisa phakathi kwendawo epholile kanye nokuphela okubandayo kwe-reactor.
3, Thola indawo yokusebenza kanye nomoya we-reactor. Lokhu kufaka phakathi ukuthi amamojula we-TEC, amamojula okupholisa ugesi we-thermoelectric azosebenza endaweni engenalutho noma emkhathini ojwayelekile, i-nitrogen eyomile, umoya omile noma onyakazayo kanye nezinga lokushisa elizungezile, okucatshangelwa kulo izinyathelo zokushisa ezishisayo (i-adiabatic) futhi kunqunywa umphumela wokuvuza kokushisa.
4. Thola into esebenzayo yezinto ze-thermoelectric kanye nobukhulu bomthwalo oshisayo. Ngaphezu kwethonya lokushisa kokugcina okushisayo, izinga lokushisa elincane noma umehluko omkhulu wokushisa ongafinyelelwa yizici ze-TEC N,P kunqunywa ngaphansi kwezimo ezimbili zokungalayishwa kanye ne-adiabatic, empeleni, izakhi ze-peltier N,P azikwazi ukuba yi-adiabatic ngempela, kodwa futhi kufanele zibe nomthwalo oshisayo, ngaphandle kwalokho akusho lutho.
5. Thola izinga lemojula ye-thermoelectric, imojula ye-TEC (izakhi ze-peltier). Ukukhethwa kochungechunge lwe-reactor kumele kuhlangabezane nezidingo zomehluko wangempela wokushisa, okungukuthi, umehluko wezinga lokushisa le-reactor kumele ube phezulu kunomehluko wangempela wokushisa odingekayo, ngaphandle kwalokho awukwazi ukuhlangabezana nezidingo, kodwa uchungechunge alukwazi ukuba luningi kakhulu, ngoba intengo ye-reactor ithuthukiswa kakhulu ngokunyuka kochungechunge.
6. Imininingwane yezinto ze-thermoelectric N,P. Ngemuva kokukhethwa kochungechunge lwedivayisi ye-peltier ethi N,P element, imininingwane ye-peltier N,P element ingakhethwa, ikakhulukazi ukusebenza kwamanje kwezinto ezipholile ze-peltier N,P. Ngenxa yokuthi kunezinhlobo ezimbalwa zama-reactor ezingahlangabezana nomehluko wokushisa nokukhiqizwa okubandayo ngesikhathi esisodwa, kodwa ngenxa yezimo zokusebenza ezihlukene, i-reactor enamandla amancane kakhulu okusebenza ngokuvamile iyakhethwa, ngoba izindleko zamandla ezisekelayo zincane ngalesi sikhathi, kodwa amandla aphelele e-reactor iyisici esinqumayo, amandla okufaka afanayo okunciphisa amandla okusebenza kufanele akhulise i-voltage (0.1v per pair of logari tothm), ngakho-ke i-tothm ye-logari iyanda.
7. Thola inani lezinto ze-N,P. Lokhu kusekelwe emandleni okupholisa aphelele e-reactor ukuze kuhlangatshezwane nezidingo zomehluko wezinga lokushisa, kufanele kuqinisekiswe ukuthi isamba somthamo wokupholisa we-reactor kuzinga lokushisa elisebenzayo likhulu kunamandla aphelele omthwalo oshisayo wento esebenzayo, ngaphandle kwalokho ayikwazi ukuhlangabezana nezimfuneko. I-inertia eshisayo yesitaki incane kakhulu, akukho ngaphezu komzuzu owodwa ngaphansi komthwalo, kodwa ngenxa ye-inertia yomthwalo (ikakhulukazi ngenxa yomthamo wokushisa womthwalo), isivinini sangempela sokusebenza sokufinyelela izinga lokushisa elibekiwe likhulu kakhulu kunomzuzu owodwa, futhi uma nje amahora ambalwa. Uma izidingo zesivinini sokusebenza zinkulu, inani lezinqwaba lizoba ngaphezulu, amandla aphelele omthwalo oshisayo akhiwa umthamo ophelele wokushisa kanye nokuvuza kokushisa (lapho izinga lokushisa liphansi, kukhulu ukuvuza kokushisa).
Lezi zici eziyisikhombisa ezingenhla ziyizimiso ezijwayelekile okufanele zicatshangelwe lapho kukhethwa ama-elementi e-thermoelectric module N,P, ngokuya ngokuthi umsebenzisi wangempela kufanele aqale akhethe amamojula okupholisa ashisayo, i-peltier cooler, imojula ye-TEC ngokwezidingo.
(1)Qinisekisa ukusetshenziswa kwezinga lokushisa le-ambient Th ℃
(2) Izinga lokushisa eliphansi Tc ℃ elifinyelelwe yisikhala esipholile noma into
(3) Umthwalo oshisayo owaziwayo Q (amandla ashisayo e-Qp, ukuvuza kokushisa kwe-Qt) W
Njengoba kunikezwe i-Th, Tc ne-Q, ama-elementi adingekayo we-Thermoelectric cooler N,P kanye nenani lama-elementi e-TEC N,P angalinganiselwa ngokuya ngejika lesici lamamojula okupholisa ashisayo, i-peltier cooler, amamojula e-TEC.
