Umehluko phakathi kwamamojula okupholisa e-thermoelectric anezigaba eziningi (amadivayisi e-peltier anezigaba eziningi) kanye namamojula okupholisa e-thermoelectric anezigaba eyodwa (izinto ze-peltier)

Umehluko phakathi kwamamojula okupholisa e-thermoelectric anezigaba eziningi (amadivayisi e-peltier anezigaba eziningi) kanye namamojula okupholisa e-thermoelectric anezigaba eyodwa (izinto ze-peltier)

Umehluko oyinhloko phakathiizakhi ze-peltier ezinezigaba eziningi, amadivayisi e-peltier kanye nezakhi ze-peltier zesigaba esisodwa , ama-cooler esigaba se-singel asesimeni sawo sangaphakathi, izinga lokushisa eliphansi kakhulu angalifinyelela, kanye nezimo zokusetshenziswa kwawo. Kalula nje, amadivayisi e-peltier esigaba esiningi aklanyelwe ukufeza umphumela wokupholisa ojulile amamojula esigaba esisodwa angenakukwazi.

Isakhiwo kanye nesimiso sokusebenza

Amamojula e-TEC esigaba esisodwa, amamojula okupholisa e-thermoelectric: Lena yindlela eyisisekelo kakhulu, equkethe ungqimba olulodwa lwezinto ze-semiconductor zohlobo lwe-P kanye nohlobo lwe-N. Uma ivuliwe, isebenzisa umphumela we-Peltier ukudlulisa ukushisa kusuka ohlangothini olulodwa (ekugcineni okubandayo) kuya kolunye uhlangothi (ekugcineni okushisayo), okufeza ukupholisa.

Amamojula okupholisa e-thermoelectric anezigaba eziningi, ama-peltier ezigaba eziningi: Angaqondwa njengamamojula amaningi e-TEC anesigaba esisodwa ahlanganiswe ngendlela "yochungechunge lokushisa", ngokuvamile ngesimo sephiramidi. Ukuphela okubandayo kwesigaba esiphezulu kusebenza njengomthombo wokushisa kokuphela okushisayo kwesigaba esingezansi. Ngale ndlela "yokupholisa ngokudlulisela", isigaba ngasinye siyaphola ngokwesisekelo sesigaba sangaphambilini, ngaleyo ndlela kufezwe ukupholisa okujulile.

Umehluko wokusebenza

Umehluko omkhulu wokushisa: Lona umehluko obaluleke kakhulu phakathi kwalokhu okubili.

Imojula yokupholisa ye-thermoelectric yesigaba esisodwa, i-peltier cooler: Umehluko omkhulu wokushisa uvame ukuba cishe ku-60-70℃.

Imojula yokupholisa ye-thermoelectric enezigaba eziningi, idivayisi ye-peltier: Ngokufaka phansi nangokubeka, umehluko wokushisa ongaphezu kuka-100℃ ungafinyelelwa. Amanye amamodeli angafinyelela ngisho namazinga okushisa aphansi kakhulu angaphansi kuka-100℃.

Umthamo wesiqandisi:

I-single-stage peltier cooler: Amandla okuqandisa (i-Qmax) makhulu kakhulu, okwenza ifaneleke ukuphatha imithwalo emikhulu yokushisa.

Isici se-peltier esinezigaba eziningi: Ngenxa yesakhiwo sayo esiyinkimbinkimbi kanye nokulahlekelwa amandla, amandla ayo okuqandisa ancipha kakhulu njengoba inani lezigaba landa. Ngakho-ke, amamojula e-thermoelectric anezigaba eziningi afanelekela izimo "zokushisa okuphansi, ukupholisa okujulile".

Isimo sohlelo lokusebenza

Imodyuli ye-thermoelectric yesigaba esisodwa(I-Peltier cooler): Ifanelekela ukushabalalisa ukushisa okuvamile noma ukupholisa ngezidingo zokushisa eziphansi, njengeziqandisi ezincane, ama-CPU cooler, amabhokisi abandayo newashisayo ezimoto, njll.

Imodyuli ye-thermoelectric enezigaba eziningi (imodyuli ye-TEC): Yakhelwe ngqo amasimu akhethekile adinga amazinga okushisa aphansi kakhulu, njenge:

Insimu yezindiza: Ukupholisa ama-infrared detectors, ama-radiation spectrometer, njll., ukuze akwazi ukusebenza emazingeni okushisa aphansi kakhulu ukuze anciphise umsindo.

Insimu yezokwelapha: Isebenza njengesibuko sokupholisa esisizayo semishini ye-nuclear magnetic resonance (MRI) ukunciphisa ukusetshenziswa kwe-helium ewuketshezi.

Amathuluzi esayensi: Asetshenziselwa izinzwa zasemanzini ajulile, imishini yelebhu ephezulu, njll.
