Kusamalira Kutentha kwa Magalimoto Amagetsi - Chotenthetsera cha PTC

PTC (Positive Temperature Coefficient) imatanthauza kuti kutentha kukakwera, kukana kumakhala kwakukulu, ndipo pali ubale wabwino. Pakadali pano, magalimoto ambiri omwe ali ndi izi, mutha kugwiritsa ntchito mwachindunji kutentha kwa batri yagalimoto ndikosavuta. Pa magalimoto amagetsi enieni, batri yagalimoto ya mabatire amphamvu kwambiri, zotenthetsera zamagetsi nthawi zambiri zimasankhazotenthetsera zamagetsi zamphamvu, chifukwa mphamvu yamagetsi ndi yokwera, mphamvu yamagetsi yomweyo imatha kusinthidwa kukhala mphamvu ya kutentha kwambiri.
Malingana ndi njira yogwirira ntchitochotenthetsera choziziritsira chamagetsiZingagawidwenso m'magulu monga mpweya wotenthetsera mwachindunji ndi mpweya wotenthetsera wosalunjika potenthetsera madzi. Mfundo yotenthetsera mpweya mwachindunji ndi yofanana ndi choumitsira tsitsi chamagetsi, pomwe mtundu wa madzi otenthetsera uli pafupi ndi mawonekedwe a kutentha. Chifukwa cha mphamvu yochepa yotulutsa batri ikayamba kutentha pang'ono m'nyengo yozizira, ukadaulo wotenthetsera batri umagwiritsidwanso ntchito ndi makampani ambiri amagalimoto. Chomwe chimagwiritsidwa ntchito kwambiri ndi chotenthetsera cha PTC chamadzi otenthetsera, kabati ndi batire motsatizana mu gawo lotenthetsera, kudzera mu chosinthira cha valavu cha njira zitatu chingasankhe ngati chichite kutentha kwa kabati ndi batri limodzi mu gawo lalikulu kapena chimodzi mwa kutentha kwapadera kwa gawo laling'ono. Ndipo imatha kukwaniritsa kutentha kwa kabati ndi batri mu dera lomwelo. Pokhala ndi chotenthetsera chamagetsi, moyo wabatire yagalimoto yamagetsiimakulitsidwa kwambiri.
