Ma Module a Thermoelectric ndi Kugwiritsa Ntchito Kwawo

Posankha zinthu za thermoelectric semiconductor N,P, choyamba muyenera kudziwa zinthu zotsatirazi:

1. Dziwani momwe zinthu za semiconductor ya thermoelectric N,P zimagwirira ntchito. Malinga ndi malangizo ndi kukula kwa mphamvu yogwirira ntchito, mutha kudziwa momwe kuziziritsira, kutentha ndi kutentha kumagwirira ntchito nthawi zonse kwa reactor, ngakhale njira yodziwika kwambiri ndiyo njira yoziziritsira, koma simuyenera kunyalanyaza momwe kutentha kwake kumagwirira ntchito komanso momwe kutentha kumagwirira ntchito nthawi zonse.

2, Dziwani kutentha kwenikweni kwa kutentha kotentha mukazizira. Popeza zinthu za thermoelectric semiconductor N,P ndi chipangizo chosiyana ndi kutentha, kuti zitheke bwino kwambiri kuziziritsa, zinthu za thermoelectric semiconductor N,P ziyenera kuyikidwa pa radiator yabwino, malinga ndi momwe kutentha kumakhalira koipa kapena koipa, kudziwa kutentha kwenikweni kwa kutentha kotentha kwa zinthu za thermoelectric semiconductor N,P zikazizira, ziyenera kudziwika kuti chifukwa cha mphamvu ya kutentha, kutentha kwenikweni kwa kutentha kotentha kwa zinthu za thermoelectric semiconductor N,P nthawi zonse kumakhala kokwera kuposa kutentha kwa pamwamba pa radiator, nthawi zambiri kumakhala kochepera magawo khumi a digiri, kuposa madigiri ochepa, madigiri khumi. Mofananamo, kuwonjezera pa kutentha kotentha kotentha, palinso kutentha kosiyanasiyana pakati pa malo ozizira ndi ozizira a zinthu za thermoelectric semiconductor N,P.

3, Dziwani malo ogwirira ntchito ndi mlengalenga wa zinthu za thermoelectric semiconductor N,P. Izi zikuphatikizapo ngati zigwire ntchito mu vacuum kapena mumlengalenga wamba, nayitrogeni youma, mpweya wosasuntha kapena woyenda komanso kutentha kwa mlengalenga, komwe kuyeza kutentha (adiabatic) kumaganiziridwa ndipo zotsatira za kutuluka kwa kutentha zimatsimikiziridwa.

4. Dziwani chinthu chogwirira ntchito cha zinthu za semiconductor ya thermoelectric N,P ndi kukula kwa katundu wotentha. Kuwonjezera pa mphamvu ya kutentha kwa mbali yotentha, kusiyana kochepa kwa kutentha kapena kutentha kwakukulu komwe stack ingapeze kumatsimikiziridwa pansi pa mikhalidwe iwiri ya no-load ndi adiabatic, kwenikweni, zinthu za semiconductor ya thermoelectric N,P sizingakhale adiabatic kwenikweni, komanso ziyenera kukhala ndi katundu wotentha, apo ayi sizingakhale ndi tanthauzo.

Dziwani kuchuluka kwa zinthu za semiconductor ya thermoelectric N,P. Izi zimachokera ku mphamvu yonse yoziziritsira ya zinthu za semiconductor ya thermoelectric N,P kuti zikwaniritse zofunikira za kusiyana kwa kutentha, ziyenera kuwonetsetsa kuti kuchuluka kwa mphamvu yoziziritsira ya zinthu za semiconductor ya thermoelectric pa kutentha kogwira ntchito kuli kwakukulu kuposa mphamvu yonse ya katundu wotentha wa chinthu chogwira ntchito, apo ayi sizingakwaniritse zofunikira. Kuchuluka kwa kutentha kwa zinthu za thermoelectric ndi kochepa kwambiri, osapitirira mphindi imodzi pansi pa katundu wopanda katundu, koma chifukwa cha kuchepa kwa katundu (makamaka chifukwa cha mphamvu ya kutentha ya katundu), liwiro lenileni logwira ntchito kuti lifike kutentha komwe kwayikidwa ndi lalikulu kwambiri kuposa mphindi imodzi, ndipo limatalika ngati maola angapo. Ngati zofunikira pa liwiro logwira ntchito ndi zazikulu, chiwerengero cha milu chidzakhala chochulukirapo, mphamvu yonse ya katundu wotentha imapangidwa ndi mphamvu yonse ya kutentha kuphatikiza kutayikira kwa kutentha (kutentha kotsika, kutentha kumatayikira kwambiri).
