Ukukhetha amamojula okupholisa i-thermoelectric anezigaba eziningi (idivayisi ye-peltier enezigaba eziningi) kuyinkimbinkimbi kakhulu kunokukhetha amamojula avamile e-thermoelectric anezigaba eyodwa, i-peltier cooler ngoba ihilela isakhiwo "se-cascade" futhi inezidingo eziphakeme zokuphathwa kokushisa kanye nokuqhathaniswa kwamapharamitha kagesi.
Isinyathelo 1: Chaza izidingo eziyinhloko (izimo zokufaka)
Ngaphambi kokubheka amamodeli athile, "izinkomba eziqinile" ezintathu ezilandelayo kumele zinqunywe njengoba zakha isisekelo sokukhetha:
Izinga lokushisa eliqondiwe (Tc) kanye nezinga lokushisa lokushisa elishisayo (Th):
Kufanele kufinyelelwe izinga lokushisa elingakanani ekugcineni kokubanda? (Isibonelo: -40°C)
Uyini umthamo omkhulu wokushisa we-hot end? (Ngokuvamile yakhelwe njengo-25°C noma 50°C).
Bala umehluko wokushisa (ΔT): ΔT = Th – Tc. Ama-chip anezigaba eziningi avame ukusetshenziswa ezimweni lapho i-ΔT > 70°C.
Umthwalo wokushisa (Qc):
Ingakanani amandla (W) into ezopholiswa ekhipha?
Uma ungaqiniseki, kuyadingeka ukubala ukushisa okuphelele okukhiqizwe yinto, okuhlanganisa ukushisa kwangaphakathi, ukushisa komoya, kanye nokushisa kwemisebe.
Isikhala esitholakalayo kanye nokunikezwa kwamandla:
Imikhawulo yosayizi wokufakwa (ubude nobubanzi)?
Ingabe i-voltage engaguquki yokunikezwa kwamandla (njenge-12V, 24V) noma i-current engaguquki? Uyini umkhawulo wamandla aphezulu?
Isinyathelo 2: Qonda amapharamitha ayisihluthulelo (izinkomba eziyinhloko)
Amapharamitha amamojula e-peltier anezigaba eziningi, amadivayisi e-pletier anezigaba eziningi anobudlelwano obuqinile. Gxila kulezi ezine ezilandelayo:
Inani lezigaba (Izigaba):
Lesi yisici esivelele kakhulu samamojula e-thermoelectric anezigaba eziningi, izakhi ze-peltier. Ngokuvamile, kunezigaba ezimbili, izigaba ezintathu, noma ngisho nezigaba eziyisithupha zemojula yokupholisa ye-thermoelectric.
Umthetho oyisisekelo: Uma izigaba eziningi, umehluko wokushisa ongatholakala ukhulu, kodwa amandla okupholisa (Qc) azoba mancane futhi intengo izoba phezulu. Ngokuvamile, umehluko wokushisa ophezulu wesigaba esisodwa cishe u-60-70°C. Uma kudingeka izinga lokushisa elingu--80°C noma ngaphansi, imodyuli ye-peltier enezigaba eziningi kumele ikhethwe.
Umthamo wokupholisa ophezulu (Qmax):
Kubhekisela kumthamo omkhulu wokumunca ukushisa lapho umehluko wokushisa ungu-0.
Isiphakamiso sokukhetha: Amandla okupholisa angempela (Qc) ngesikhathi sokusebenza mancane kakhulu kune-Qmax. Ngokuvamile kunconywa ukuthi i-Qmax kufanele ibe ngumthwalo wakho wokushisa ophindwe ka-1.3 kuya ku-2, okushiya umkhawulo ukuqinisekisa ukusebenza kahle kanye nesikhathi sokuphila.
Umehluko omkhulu wokushisa (ΔTmax):
Kubhekisele kumehluko omkhulu wokushisa ongafinyelelwa yi-thermoelectric cooling module, i-peltier element (lapho umthamo wokupholisa u-0).
Isiphakamiso sokukhetha: I-ΔTmax ekhethiwe kufanele ibe phezulu ngo-10-20% kunomehluko wangempela wokushisa owudingayo.
I-voltage kanye nogesi (i-Vmax / i-Imax):
Ukumelana kwangaphakathi kwemodyuli yokupholisa ye-thermoelectric enezigaba eziningi, imodyuli ye-TEC ivame ukuba nkulu, futhi i-voltage ingaba phezulu (njenge-24V, 48V, noma ngaphezulu), kuyilapho amandla kagesi emancane kakhulu. Qiniseka ukuthi ugesi wakho ungawushayela.
Isinyathelo 3: Sebenzisa ijika lokusebenza (ukufanisa okunembile)
Lesi yisinyathelo esibaluleke kakhulu. Ungathembeli nje kuphela kumanani aphezulu ashiwo eshidini lemininingwane!
Ukusebenza kwemodyuli yokupholisa ye-thermoelectric enezigaba eziningi akuqondile.
Nquma indawo yokusebenza: Ngokuphathelene nomehluko wokushisa okuqondiwe (ΔT) kanye nomthamo wokupholisa okuqondiwe (Qc), bheka igrafu yejika.
Thola i-current efanele (i-Iop): Thola inani lamanje elihambisanayo.
Bala isilinganiso sokusebenza kahle kwamandla (i-COP): Zama ukwenza i-thermoelectric module isebenze esifundeni esine-COP ephezulu (ngokuvamile cishe u-30%-50% wamandla aphezulu), kunokuba isebenze ngomthamo ogcwele. Ukusebenza ngomthamo ogcwele kunganikeza ukupholisa okusheshayo, kodwa kukhiqiza ukushisa okweqile futhi kusebenza kahle kakhulu.
Isinyathelo 4: Isakhiwo Nokufakwa
Amamojula okupholisa e-thermoelectric asezingeni eliningi (imojula ye-TEC enezigaba eziningi) abuthakathaka kakhulu kunamamojula okupholisa e-thermoelectric asezingeni elilodwa (amamojula e-peltier asezingeni elilodwa). Lapho ukhetha uhlobo, isakhiwo esibonakalayo kumele sicatshangelwe:
Ukulinganiselwa Kosayizi:
Amamojula okupholisa e-peltier eziteji eziningi ngokuvamile awanconywa ukuthi enziwe abe makhulu kakhulu (njengamakhulu kuno-62x62mm), njengoba indawo enkulu kakhulu ingabangela kalula ukuthi amapuleti e-ceramic agobe noma aqhekeke. Ukuze kuphole endaweni enkulu, kunconywa ukusebenzisa ama-peltier mdoules amaningi amancane axhunywe ngokulingana noma ngochungechunge.
Indlela yokuxhuma:
Ukuxhumeka kochungechunge: Kunconywa. Ugesi uhambisana, kulula ukuwulawula. Uma ingxenye eyodwa yonakele, ingatholakala kalula (ngokuphuka kwesekethe).
Ukuxhumeka okuhambisanayo: Akukhuthazwa. Uma ukumelana kwangaphakathi kwengxenye eyodwa kushintsha, ukusatshalaliswa kwamanje ngeke kungalingani, okuholela esimeni "sokuncintisana kwamanje", okusheshisa umonakalo.
