I-heater ye-PTC iwuhlobo lwesici sokushisa esisebenza ngokusekelwe endaweni kagesi yezinto ezithile lapho ukumelana kwazo kukhula khona ngokushisa. Lezi zinto zikhombisa ukwanda kokumelana nokukhuphuka kwezinga lokushisa, futhi izinto ezisetshenziswa kakhulu ze-semiconductor zifaka i-zinc oxide (ZnO) ceramics.
Umgomo we-heater ye-PTC ungachazwa kanje:
1. I-Positive Temperature Coefficient (PTC): Isici esibalulekile sezinto ze-PTC ukuthi ukumelana kwazo kuyanda njengoba izinga lokushisa likhuphuka. Lokhu kuphambene nezinto ezinezinga lokushisa elibi (NTC), lapho ukumelana kuncipha nezinga lokushisa.
2. Ukuzilawula: Izishisi ze-PTC ziyizinto ezizilawulayo. Njengoba izinga lokushisa lezinto ze-PTC likhula, ukumelana kwayo kukhuphuka. Lokhu, futhi, kunciphisa ukudlula kwamanje entweni ye-heater. Ngenxa yalokho, izinga lokukhiqiza ukushisa liyancipha, okuholela kumphumela wokuzilawula.
3. Isici Sokuphepha: Imvelo yokuzilawula yama-heaters e-PTC isici sokuphepha. Lapho izinga lokushisa le-ambient likhuphuka, ukumelana kwezinto ze-PTC kuyanda, kukhawulela inani lokushisa elikhiqizwayo. Lokhu kuvimbela ukushisa ngokweqile futhi kunciphisa ingozi yomlilo.
4. Izinhlelo zokusebenza: Izifudumezi ze-PTC zivame ukusetshenziswa ezinhlelweni ezahlukene ezifana nezifudumezi zasemkhathini, amasistimu okushisa ezimoto, nezinto zikagesi. Banikeza indlela ethembekile nephumelelayo yokukhiqiza ukushisa ngaphandle kwesidingo samadivayisi okulawula izinga lokushisa angaphandle.
Kafushane, isimiso se-heater ye-PTC sisekelwe ku-coefficient yokushisa enhle yezinto ezithile, ezivumela ukuthi zizilawule ngokwazo ukuphuma kwazo kokushisa. Lokhu kuzenza ziphephe futhi zonge amandla ezinhlelweni zokufudumeza ezahlukahlukene.
