PTC heater ke mofuta oa lisebelisoa tse futhumatsang tse sebetsang ho latela thepa ea motlakase ea lisebelisoa tse itseng moo ho hanyetsa ha bona ho eketsehang ka mocheso. Lisebelisoa tsena li bonts'a ho eketseha ha khanyetso ka ho phahama ha mocheso, 'me lisebelisoa tse sebelisoang ka tloaelo tsa semiconductor li kenyelletsa li-ceramics tsa zinc oxide (ZnO).
Molao-motheo oa heater ea PTC o ka hlalosoa ka tsela e latelang:
1. Positive Temperature Coefficient (PTC): Ntho ea bohlokoa ea thepa ea PTC ke hore ho hanyetsa ha bona ho eketseha ha mocheso o ntse o phahama. Sena se fapane le lisebelisoa tse nang le mocheso o fokolang oa mocheso (NTC), moo ho hanyetsa ho fokotsehang ka mocheso.
2. Ho Itlhokomela: Lifuthumatsi tsa PTC ke likarolo tse itlhophisang. Ha mocheso oa thepa ea PTC o ntse o eketseha, ho hanyetsa ha oona hoa nyoloha. Sena, le sona, se fokotsa ho feta hona joale ka karolo ea heater. Ka lebaka leo, tekanyo ea ho hlahisa mocheso e fokotseha, e lebisang ho phello e ikemetseng.
3. Tšobotsi ea Tšireletseho: Mokhoa oa ho itlhokomela oa li-heaters tsa PTC ke tšobotsi ea tšireletso. Ha mocheso oa tikoloho o phahama, khanyetso ea thepa ea PTC ea eketseha, e fokotsa boholo ba mocheso o hlahisoang. Sena se thibela mocheso o feteletseng le ho fokotsa kotsi ea mollo.
4. Lisebelisoa: Lifuthumatsi tsa PTC li sebelisoa hangata lits'ebetsong tse fapaneng joalo ka lihitara tsa sebaka, lisebelisoa tsa ho futhumatsa likoloi, le lisebelisoa tsa elektroniki. Ba fana ka mokhoa o ka tšeptjoang le o sebetsang oa ho hlahisa mocheso ntle le tlhokahalo ea lisebelisoa tsa ho laola mocheso ka ntle.
Ka kakaretso, molao-motheo oa mocheso oa PTC o itšetlehile ka mocheso o motle oa mocheso oa thepa e itseng, e leng se ba lumellang hore ba iketsetse ho laola mocheso oa bona. Sena se etsa hore li bolokehe le ho boloka matla a mangata lits'ebetsong tse fapaneng tsa ho futhumatsa.
