Muukadaulo wamakono wowunikira magalimoto, nyali za halogen, HID (nyali zotulutsa mpweya wochuluka kwambiri) ndi nyali za LED (light-emitting diode) ndi mitundu itatu yodziwika bwino. Nyali iliyonse ili ndi ubwino wake ndi zovuta zake, koma pansi pa mphamvu zofanana, kutentha kopangidwa ndi nyali zosiyana kumakhala ndi kusiyana kwakukulu.
Nyali za halogen
Nyali za halogen ndi mtundu wakale wa nyali zamagalimoto. Mfundo yake yogwirira ntchito ndi yofanana ndi ya nyali wamba wamba, ndipo ulusi wa tungsten umatenthedwa ndi mphamvu yamagetsi kuti ukhale wowala. Chigoba chagalasi cha nyali ya halogen chimadzazidwa ndi mpweya wa halogen (monga ayodini kapena bromine), yomwe imatha kukulitsa moyo wa filament ndikuwonjezera kuwala.
Kuphatikiza apo, nyali za halogen zimapanga kutentha kwambiri, zimadya mphamvu zambiri, ndipo kutentha kumatha kufika madigiri 200 Celsius pogwira ntchito.
Nyali za HID, zomwe zimadziwikanso kuti nyali zotulutsa mpweya wothamanga kwambiri, zimatulutsa kuwala podzaza babu ndi mpweya wa inert monga xenon ndikupanga arc pansi pamagetsi apamwamba.
Kutentha kwa nyali za HID kumatha kufika madigiri 300-400 Celsius mukamagwira ntchito kuposa mphindi khumi mutayatsa, pomwe kutentha kunja kwa babu kumatsika pang'ono kuposa kutentha kwapakati, ndipo kuzirala kwachilengedwe kumagwiritsidwa ntchito nthawi zambiri.
Magetsi a LED ndi mtundu wa nyali zamagalimoto zomwe zadziwika kwambiri m'zaka zaposachedwa. Imatulutsa kuwala kupyolera mu kuwala kotulutsa diode pansi pa zochitika zamakono, ndipo imakhala ndi makhalidwe apamwamba kwambiri komanso kupulumutsa mphamvu.
Kutentha kopangidwa ndi nyali za LED kumakhala kochepa, nthawi zambiri kumakhala pafupifupi 80 digiri Celsius. Izi zili choncho chifukwa mphamvu ya electro-optical conversion ya magetsi a LED ndi apamwamba, ndipo mphamvu zambiri zimasinthidwa kukhala mphamvu yowunikira osati mphamvu ya kutentha.
Chifukwa chiyani LEDmutumagetsi amatulutsa kutentha kochepa?
Kutembenuka kwa electro-optical
Kuwongolera kwa electro-optical kutembenuka kwa magetsi a LED ndikokwera kwambiri, ndipo mphamvu zambiri zamagetsi zimatha kusinthidwa kukhala mphamvu zowunikira. Mosiyana ndi izi, nyali za halogen ndi nyali za HID zimapanga kutentha kwakukulu panthawi yotulutsa kuwala.
Kugwiritsa ntchito mphamvu zochepa
Nyali za LED zimakhala ndi mphamvu zochepa, nthawi zambiri zimayambira pa ma watts angapo mpaka makumi a watts, pamene nyali za halogen ndi nyali za HID zimakhala ndi mphamvu zambiri.
Zida za semiconductor
Nyali za LED zimagwiritsa ntchito zida za semiconductor kuti zitulutse kuwala, zomwe sizimapanga kutentha kwakukulu monga tungsten filaments pamene panopa ikudutsa. Njira yopangira kuwala kwa zida za semiconductor ndi yabwino komanso yokhazikika.
Mapangidwe a kutentha kwapakati
Ngakhale nyali za LED zokha zimatulutsa kutentha pang'ono, zimakhudzidwa kwambiri ndi kutentha, kotero nyali za LED zimafunikira ntchito zina kuti zithandizire kuyatsa konseku kuziziritsa kutentha.
Pali njira zambiri zochitirakuwononga kutentha kwa nyali za LED. Njira yotchuka kwambiri yochotsera kutentha ndi radiator + fan.
Nyali ya LED yokhala ndi kutentha koyenera
IziK11 nyali ya nyali ya LEDamapangidwa ndi aluminiyumu ya ndege, yomwe imakhala yolimba kwambiri komanso imataya kutentha. Mkati mwa nyaliyo amagwiritsa ntchito superconducting zinthu zamkuwa zotentha komanso kuzizira kwa fan fan, zomwe sizimangowoneka bwino, komanso zimakhala ndi kutentha kwabwino komanso moyo wautumiki.
Nyali iyi imatha kupirira kutentha kwambiri komanso kutsika kwa kutentha, ndipo imakhala ndi chowotcha chopanda madzi, chomwe chingakupatseni zowunikira zomveka ngakhale m'malo ovuta kwambiri.
Ngati mukufuna kudziwa zambiri kapena kugula nyali zamagalimoto, chonde lemberani akuluakulu a WWSBIU mwachindunji:
