Lingaliro loyambirira la zowumitsira tsitsi ndilosavuta, koma kupanga imodzi kuti idye kwambiri kumafuna kulingalira mozama zachitetezo.Chowumitsira tsitsi mopangaamayenera kuneneratu momwe chowumitsira tsitsi chawo chingagwiritsidwe ntchito molakwika.Kenako amayesa kupanga chinthu chomwe chizikhala chotetezeka m'malo osiyanasiyana. apa pali zina mwachitetezo zowumitsa tsitsi zomwe nthawi zambiri zimakhala:
Chosinthira chitetezo chodula- Khungu lanu limatha kuwotchedwa ndi kutentha kopitilira 140 degrees Fahrenheit (pafupifupi madigiri 60 Celsius).Kuonetsetsa kuti mpweya wotuluka mu mbiya suyandikire kutentha kumeneku, zowumitsira tsitsi zimakhala ndi mtundu wina wa sensa ya kutentha yomwe imayenda mozungulira ndikuzimitsa galimoto pamene kutentha kwakwera kwambiri.Chowumitsira tsitsi ichi ndi ena ambiri amadalira mzere wosavuta wa bimetallic ngati chosinthira chodulidwa.
Mzere wa Bimetallic- Zopangidwa ndi mapepala azitsulo ziwiri, zonse zimakula zikatenthedwa koma pamitengo yosiyana.Kutentha kukakwera mkati mwa chowumitsira tsitsi, mzerewo umatenthedwa ndikupindika chifukwa chitsulo chimodzi chakula kuposa china.Ikafika pamalo enaake, imayendetsa chosinthira chomwe chimadula mphamvu kupita ku chowumitsira tsitsi.
Thermal fuse- Kuti mutetezedwenso kuti musatenthedwe ndi kutenthedwa ndi moto, nthawi zambiri pamakhala fuse yotentha yomwe imaphatikizidwa mugawo lotenthetsera.Fuse iyi imawomba ndikuphwanya dera ngati kutentha ndi komweko kuli kokwera kwambiri.
Insulation- Popanda kutchinjiriza koyenera, kunja kwa chowumitsira tsitsi kumatentha kwambiri mpaka kukhudza.Mukachigwira ndi mbiya mutachigwiritsa ntchito, chikhoza kutentha dzanja lanu kwambiri.Pofuna kupewa izi, zowumitsira tsitsi zimakhala ndi chishango cha kutentha cha zinthu zotetezera zomwe zimayika mbiya yapulasitiki.
Mawonekedwe achitetezo- Mpweya ukakokedwa mu chowumitsira tsitsi pomwe masamba amakupiza amatembenuka, zinthu zina kunja kwa chowumitsira tsitsi zimakokeranso komwe kumalowera.Ichi ndichifukwa chake mupeza chophimba chawaya chomwe chikuphimba mabowo a mpweya mbali zonse za chowumitsira.Mutagwiritsa ntchito chowumitsira tsitsi kwakanthawi, mupeza zomangira zambiri kunja kwa chinsalu.Izi zikadachulukana mkati mwa chowumitsira tsitsi, zitha kupsa ndi chotenthetsera kapena kutsekereza injini yokha.Lint yochuluka imatha kulepheretsa mpweya kulowa mu chowumitsira, ndipo chowumitsira tsitsi chimatenthedwa ndi mpweya wochepa wochotsa kutentha kopangidwa ndi koyilo ya nichrome kapena chinthu china chotenthetsera.Zoumitsira tsitsi zatsopano zaphatikizanso ukadaulo wina wochokera ku chowumitsira zovala: chophimba chochotsamo chosavuta kuyeretsa.
Grill kutsogolo- Mapeto a mbiya ya chowumitsira tsitsi amakutidwa ndi grill yopangidwa ndi zinthu zomwe zimatha kupirira kutentha kochokera ku chowumitsira.Chotchinga ichi chimapangitsa kuti zikhale zovuta kwa ana ang'onoang'ono (kapena anthu ena okonda kufunsa) kuyika zala zawo kapena zinthu zina pansi pa mbiya ya chowumitsira, pomwe amatha kuwotchedwa pokhudzana ndi chotenthetsera.
