Ngokwezidingo zokukhetha amamojula wokupholisa we-thermoelectric, amamojula we-TEC, izakhi ze-peltier

Ngokwezidingo zokukhetha amamojula wokupholisa we-thermoelectric, imojula ye-TEC, izakhi ze-peltier.

Izidingo ezijwayelekile:

①, uma kubhekwa 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

Uma kunikezwe i-Th, Tc kanye ne-Q, inqwaba edingekayo kanye nenani lezinqwaba lingalinganiselwa ngokuya ngejika lesici semojula ye-thermoelectric, idivayisi ye-peltier.

Njengomthombo obandayo okhethekile, imojula yokupholisa ye-thermoelectric(TE cooler) inezinzuzo nezici ezilandelayo ekusetshenzisweni kobuchwepheshe:

1, Awudingi noma yisiphi isiqandisi, singasebenza ngokuqhubekayo, akukho mthombo wokungcola akukho zingxenye ezijikelezayo, ngeke kukhiqize umphumela wokujikeleza, azikho izingxenye ezishelelayo ziyidivayisi eqinile, akukho vibration, umsindo, impilo ende, ukufakwa kalula.

2,

I-5, Ukusetshenziswa okuphambene kwe-Thermoelectric Module, I-Pletier Module, idivayisi ye-Pletier ikhiqiza amandla okushintsha izinga lokushisa, ijeneretha yamandla kagesi we-Thermoelectric, i-thermoelectric generator, i-TEG module ngokuvamile ilungele ukukhiqizwa kwamandla okuphansi kwesifunda.

6, amandla wesici sokupholisa esisodwa semojula ye-thermoelectric yokupholisa i-peltier module TE incane kakhulu, kodwa inhlanganisela ye-thermoelectric semiconductor N,P izakhi, ezinohlobo olufanayo lwezakhi ze-thermoeletric uchungechunge, indlela ehambisanayo ehlanganiswe ohlelweni lokupholisa, amandla angenziwa amakhulu kakhulu, ngakho amandla okupholisa angafinyelelwa kububanzi bezinkulungwane ezimbalwa zama-watts.

I-7, Ububanzi bomehluko wokushisa we-peltier modules thermoelectric modules, ukusuka kumazinga okushisa amahle angu-90 ℃ kuya ekushiseni okungekuhle okungu-130 ℃ kungafinyelelwa.

Imojula yokupholisa ye-thermoelectric Peltier module (Imojula ye-Thermoelectric) iwumsebenzi wokufaka ugesi we-DC, kufanele ifakwe ugesi ozinikele.

1, DC amandla. Inzuzo ye-DC power supply ukuthi ingasetshenziswa ngokuqondile ngaphandle kokuguqulwa, futhi okubi ukuthi i-voltage kanye namanje kufanele kusetshenziswe ku-peltier module.peltier element, i-thermoelectric module, kanti ezinye zingaxazululwa ngochungechunge kanye nemodi ehambisanayo yamamojula we-TEC, izakhi ze-peltier, amamojula we-thermoelectric.

2. Ac current. Lokhu ukunikezwa kwamandla okuvame kakhulu, okumele kulungiswe ku-DC ukuze kusetshenziswe ukupholisa kwe-thermoelectric modlules amamojula we-TEC, amamojula we-peltier. Njengoba i-Pletier module thermoelectric cooling module iyi-voltage ephansi kanye nedivayisi yamanje ephezulu, ukusetshenziswa kwebhakede lokuqala, ukulungiswa, ukuhlunga, okunye ukuze kube lula ukusetshenziswa kokulinganisa izinga lokushisa, ukulawula izinga lokushisa, ukulawula kwamanje nokunye.

3, Ngenxa yokuthi imojuli ye-Thermoelectric ingumthombo wamandla we-DC, i-ripple coefficient yokuphakelwa kwamandla kufanele ibe ngaphansi kuka-10%, ngaphandle kwalokho inomthelela omkhulu kumphumela wokupholisa.

4,I-voltage esebenzayo kanye ne-current yedivayisi ye-peltier kumele ihlangabezane nezidingo zedivayisi esebenzayo, isibonelo: idivayisi engu-12706, i-127 iyimojula ye-thermoelectric imibhangqwana, i-PN ye-logarithm yombhangqwana kagesi, i-voltage yomkhawulo wokusebenza wemojula ye-thermoelectric V= i-logarithm yombhangqwana kagesi × 0.11, 06 inani eliphezulu lamanje elivunyelwe.

I-5, Amandla wemishini yokupholisa ye-thermoelectric ebandayo kanye nokushintshaniswa kokushisa kufanele abuyiselwe ekamelweni lokushisa lapho ukuphela kokubili (ngokuvamile kuthatha imizuzu engaphezu kwe-5 ukufeza), ngaphandle kwalokho kulula ukubangela umonakalo kumjikelezo we-elekthronikhi kanye nokuqhekeka kwamapuleti e-ceramic.

I-6, Isekethe ye-elekthronikhi ye-thermoelectric cooler power supply ivamile.

Imojuli yokupholisa ye-thermoelectric yesiteji esi-3: Ukucaciswa kwe-TES3-20102T125:
