Ukukhetha iimodyuli zokupholisa ze-thermoelectric ezinezigaba ezininzi (isixhobo se-peltier esinezigaba ezininzi) kunzima kakhulu kunokukhetha iimodyuli ze-thermoelectric eziqhelekileyo ezinezigaba esinye, i-peltier cooler kuba ibandakanya isakhiwo "se-cascade" kwaye ineemfuno eziphezulu zolawulo lobushushu kunye nokuhambelana kweeparamitha zombane.
Inyathelo 1: Chaza iimfuno eziphambili (iimeko zokufaka)
Ngaphambi kokuba ujonge kwiimodeli ezithile, kufuneka kuchongwe ezi “mpawu ziqinileyo” zintathu zilandelayo njengoko zakha isiseko sokhetho:
Ubushushu obujoliswe kuko (Tc) kunye nobushushu obushushu (Th):
Lingakanani ubushushu obufanele bufikelele kwisiphelo sokubanda? (Umzekelo: -40°C)
Ingakanani amandla okuphelisa ubushushu aphezulu kwi-hot end? (Idla ngokuba yi-25°C okanye i-50°C).
Bala umahluko wobushushu (ΔT): ΔT = Th – Tc. Iitships ezinamanqanaba amaninzi zihlala zisetyenziswa kwiimeko apho ΔT > 70°C.
Umthwalo wobushushu (Qc):
Ingakanani i-wattage (W) ekhutshwa yinto eza kupholiswa?
Ukuba awuqinisekanga, kuyimfuneko ukubala ubushushu obupheleleyo obuveliswa yinto leyo, kuquka ubushushu bangaphakathi, ubushushu bokuqhuba, kunye nobushushu bemitha.
Indawo ekhoyo kunye nombane ofumanekayo:
Imida yobungakanani bofakelo (ubude nobubanzi)?
Ingaba i-voltage engaguqukiyo yombane (efana ne-12V, 24V) okanye yi-constant current? Ingakanani i-current esezantsi?
Inyathelo lesi-2: Qonda iiparameter eziphambili (izikhombisi eziphambili)
Iiparameter zeemodyuli ze-peltier ezinamanqanaba amaninzi, izixhobo ze-pletier ezinamanqanaba amaninzi zinobudlelwane obuqinileyo. Gxila kwezi zine zilandelayo:
Inani lamanqanaba (Amanqanaba):
Olu lolona phawu lubalaseleyo lweemodyuli ze-thermoelectric ezinamanqanaba amaninzi, izinto ze-peltier. Ngokwesiqhelo, kukho izigaba ezi-2, izigaba ezi-3, okanye izigaba ezi-6 zemodyuli yokupholisa ye-thermoelectric.
Umthetho oqhelekileyo: Okukhona izigaba zininzi, kokukhona umahluko wobushushu mkhulu onokufikelelwa, kodwa amandla okupholisa (Qc) aya kuba mncinci kwaye ixabiso liya kuba phezulu. Ngokubanzi, umahluko ophezulu wobushushu wesigaba esinye umalunga nama-60-70°C. Ukuba kufuneka ubushushu obuyi--80°C okanye ngaphantsi, kufuneka kukhethwe imodyuli ye-peltier enamanqanaba amaninzi.
Ubuninzi bomthamo wokupholisa (Qmax):
Ibhekisa kumthamo ophezulu wokufunxa ubushushu xa umahluko wobushushu uyi-0.
Ingcebiso yokukhetha: Umthamo wokupholisa (Qc) ngexesha lokusebenza mncinci kakhulu kuneQmax. Ngokuqhelekileyo kucetyiswa ukuba iQmax ifanele ibe ngumthwalo wakho wobushushu ophindwe kayi-1.3 ukuya kwezi-2, nto leyo eshiya umda ukuqinisekisa ukusebenza kakuhle kunye nobomi.
Umahluko omkhulu wobushushu (ΔTmax):
Ibhekisa kumahluko opheleleyo wobushushu onokufikelelwa yimodyuli yokupholisa ye-thermoelectric, into ye-peltier (xa amandla okupholisa eyi-0).
Ingcebiso yokukhetha: I-ΔTmax ekhethiweyo kufuneka ibe phezulu nge-10-20% kunomahluko wokwenyani wobushushu obufunekayo.
I-Voltage kunye nomsinga (i-Vmax / i-Imax):
Ukumelana kwangaphakathi kwemodyuli yokupholisa ye-thermoelectric enamanqanaba amaninzi, imodyuli ye-TEC idla ngokuba nkulu, kwaye i-voltage inokuba phezulu (njenge-24V, 48V, okanye nangaphezulu), ngelixa umbane umncinci. Qinisekisa ukuba umbane wakho unokuwuqhuba.
Inyathelo lesi-3: Sebenzisa i-performance curve (ukufanisa ngokuchanekileyo)
Eli lelona nyathelo libaluleke kakhulu. Musa ukuthembela kuphela kumaxabiso aphezulu achazwe kwiphepha leenkcukacha!
Ukusebenza kwemodyuli yokupholisa ye-thermoelectric enamanqanaba amaninzi akuhambelani nomgca.
Misela indawo yokusebenza: Kumahluko wobushushu obujoliswe kubo (ΔT) kunye nomthamo wokupholisa (Qc), jonga igrafu yejika.
Fumana i-current efanelekileyo (i-Iop): Fumana ixabiso langoku elifanelekileyo.
Bala umlinganiselo wokusebenza kakuhle kwamandla (i-COP): Zama ukwenza imodyuli ye-thermoelectric isebenze kummandla one-COP ephezulu (ngesiqhelo malunga ne-30%-50% yombane ophezulu), endaweni yokusebenza ngamandla apheleleyo. Ukusebenza ngamandla apheleleyo kunokubonelela ngokupholisa ngokukhawuleza, kodwa kuvelisa ubushushu obugqithisileyo kwaye kusebenza kancinci kakhulu.
Inyathelo lesi-4: Ulwakhiwo kunye nofakelo
Iimodyuli zokupholisa ze-thermoelectric ezinezigaba ezininzi (imodyuli ye-TEC enezigaba ezininzi) zibuthathaka ngakumbi kuneemodyuli zokupholisa ze-thermoelectric ezinezigaba esinye (iimodyuli ze-peltier ezinezigaba esinye). Xa ukhetha uhlobo, kufuneka kuthathelwe ingqalelo ulwakhiwo olubonakalayo:
Imida yobukhulu:
Iimodyuli zokupholisa ze-peltier ezineziteji ezininzi azikhuthazwa ukuba zenziwe zibe nkulu kakhulu (ezifana nezinkulu kune-62x62mm), njengoko indawo enkulu kakhulu inokubangela ukuba iipleyiti zeseramikhi zigobe okanye ziqhekeke. Ukupholisa okukhulu, kucetyiswa ukuba kusetyenziswe ii-peltier mdoules ezininzi ezincinci ezidityaniswe ngaxeshanye okanye ngochungechunge.
Indlela yoqhagamshelo:
Uqhagamshelo lothotho: Kucetyiswa. Umsinga uhambelana, kulula ukuwulawula. Ukuba iqhekeza elinye lonakele, linokufunyanwa lula (ngokuqhekeka kwesekethe).
Uqhagamshelo oluhambelanayo: Akukhuthazwa. Ukuba ukumelana kwangaphakathi kwento enye kuyatshintsha, usasazo lwangoku aluyi kulingana, nto leyo ekhokelela kwisiganeko "sokhuphiswano lwangoku", nto leyo ekhawulezisa umonakalo.
