Kev ua tau zoo
Lub TIG-BiTe-P / N-2 thermoelectric ingot yog zus nrog cov alloy ntawm Bi, Sb, Te, Se, tshwj xeeb doping thiab peb cov txheej txheem crystallizing tshwj xeeb.Lub Bi2Te3-raws li thermoelectric ingot yog zus tshwj xeeb thiab optimized rau ua cov thermoelectric modules uas siv los hloov cov cua sov qhov chaw xws li 100 ℃ (373K) mus rau 350 ℃ (623K) rau hauv hluav taws xob.Feem ntau, qhov nruab nrab ntawm qhov zoo ZT ntawm peb cov p-hom thiab n-hom ingots tshaj qhov kub ntawm 300K txog 600K yog loj dua 0.7.Lub module ua nrog xws li ingots tuaj yeem ua tiav 5% kev ua haujlwm nrog 250 ℃ Delta T. Meanwhile, peb ingot yog featured nrog zoo mechanical zog thiab ruaj khov khoom, muab lub pob zeb tseem ceeb rau kev ua tau zoo thiab txhim khu kev qha fais fab modules.
