Idivaysi ye-thermoelectric iguqula amandla esebenzisa i-voltage ekhiqizwa umehluko wokushisa phakathi kwamaphethelo amabili wezinto ezibonakalayo - uyakwazi ukuguqula amandla kagesi, angasetshenziswa empilweni yansuku zonke. Amadivayisi akhona we-thermoelectric aqinile, ngoba aqukethe ama-electrodes asuselwa kwizinsimbi eziqinile kanye nama-semiconductors, avimbela ukumuncwa ngokugcwele kwemithombo yokushisa evela ezindaweni ezingalingani. Ngakho-ke, ukucwaninga okusanda kwenzeka kuqhutshwa ngenkuthalo ekuthuthukisweni kwamadivayisi we-thermoelectric aguqukayo angakhiqiza amandla asondelene nemithombo ehlukahlukene yokushisa, kufaka phakathi lezo zikhumba zabantu.
Ososayensi abavela eKorea Institute of Science and Technologies (Kist) bathuthukise amadivaysi afihle futhi aguquguqukayo ama-thermoelectric anezimpawu eziphakeme zamandla ngenxa yokuguquguquka okuphezulu nokusebenza kokudlulisa okushisayo. Abathuthukisi baphinde baveza uhlelo lokukhiqiza ngobuningi besebenzisa ukuhamba komsebenzi okuzenzakalelayo okubandakanya inqubo ephrintiwe.
Ngokusho kososayensi baseKorea,
Lezi zifundo zikhombisile ukuthi ngosizo lwemithombo yokushisa yangaphandle, ungasebenza ngogqoke olukhona, njengamagilavu angashisa aphezulu. Esikhathini esizayo, sizothuthukisa ipulatifomu ye-thermoelectric eguquguqukayo ezokwazi ukusebenza ngamadivayisi we-cagase, ukuthola amandla kuphela ngenxa yokushisa komzimba.
Izinto ezihlanganisiwe ezisebenzayo, ipulatifomu yedivaysi ye-thermoelectric kanye nenqubo esebenza ngokuzenzakalela eyenziwe nge-automated eyenziwe ngaphansi kwalolu cwaningo izokwazi ukukhuthaza ukuthengiswa kwamadivayisi agqokekayo angadingi amabhethri ngokuzayo.
Ngokuqondene nezindawo ezikhona ezikhona ezisetshenziselwa izifundo zamadivayisi we-thermoelectric aguqukayo, ukusebenza kwawo kwamandla okushisa kuphansi ngenxa yokuvuselelwa okuphansi kakhulu. Ukusebenza kwabo ukumuncwa kokushisa nakho kuphansi ngenxa yokuntuleka kwezimo eziguqukayo okwakha ungqimba lokufakwa kokushisa ngokuxhumana nomthombo wokushisa ohlanganisa umoya. Ukuxazulula le nkinga, amadivaysi e-thermoelectric asuselwa ezintweni eziphilayo ezinokuguquguquka okuphezulu athuthukiswa, noma kunjalo, ukusetshenziswa kwazo kumadivayisi agqokekayo akuphumeleli ngenxa yezimpawu ezimbi kakhulu ze-thermoelectric ezikhona ngokuhambisana nezinto ezisetshenziswayo ze-inorganeelyric ezisuselwa ezintweni ezingaphezulu.
Abacwaningi baseKorea bahlanganisa ukukhuphuka kwezinguquko ngenkathi benciphisa ukumelana nohlelo ngokuxhuma idivaysi esebenza kahle kakhulu ye-thermoelectric ngokususelwa ezintweni ezingaphansi kwe-noropod kuya engxenyeni yesiliva. Idivaysi entsha ikhombisile ukuguquguquka okuhle kakhulu, ngaleyo ndlela enikezela ngokuhlinzwa okuzinzile ngisho nangokugoba noma ukwelula. Ngaphezu kwalokho, izinhlayiya zensimbi ezinokuphakelayo okuphezulu zafakwa ngaphakathi kwe-tensile substrate, okwenza ukuthi kungakhuphule ukudluliswa kokushisa ngo-800% (1.4 w / mk) kanye nezizukulwane zikagesi kunezikhathi ezintathu.
