I-PTCuhlelo lokushisa i-air heaterkuyindlela evamile yokushisa ezimotweni ezintsha zamandla, ikakhulukazi ezimotweni zikagesi ezihlanzekile. Njengoba izimoto zikagesi zingenawo ugesi ongcolile okhiqizwa yizinjini zokushisa zangaphakathi, zidinga ugesi ozimeleizixazululo zokushisaI-PTC yisifinyezo se-"Positive Temperature Coefficient", esibhekisela ku-positive temperature coefficient. Ukumelana kwale nto kuyanda ngokwanda kwezinga lokushisa.
Umgomo wokusebenza weIsifudumezi somoya se-PTCukusebenzisa lesi sici sezinto ze-PTC ukukhiqiza ukushisa ngokudlulisa ugesi nge-PTC element. Lapho i-PTC element ishiswa, inani layo lokumelana lizokhula ngokukhuphuka kokushisa, ngaleyo ndlela kuncishiswe ukwanda okuqhubekayo kogesi, kufezwe umphumela ozilawulayo futhi kugcinwe umphumela wokushisa oqhubekayo. Le heater inezici zokonga amandla, izinga lokushisa eliqhubekayo, ukuphepha kanye nokuphila isikhathi eside kwenkonzo.
Ezimotweni ezintsha zamandla, ama-air heater e-PTC avame ukwakhiwa yizinto ze-PTC, ama-heat sink kanye nama-housings.Isici se-PTCiyisakhi esiyinhloko esibangela ukushisa; isinki yokushisa isetshenziselwa ukuqeda ukushisa; indlu ivikela isifudumezi ukuvimbela izingozi ezifana nokushaqeka kukagesi. Isifudumezi somoya se-PTC singafudumeza umoya ngqo noma ngokungaqondile ngokushisa isifudumezi. Indlela yokushisa umoya ngqo inesakhiwo esilula, kodwa kungase kube nezingozi zokuphepha; indlela yokushisa umoya engaqondile isebenzisa iphampu yesifudumezi ukupompa isifudumezi ku-radiator emotweni, futhi isebenzisa ukushisa okuvela kusifudumezi ukufudumeza umoya. Le ndlela igwema ukufakwa kwemisinga emikhulu nama-voltage aphezulu emotweni futhi inokuphepha okuphezulu, kodwa uhlelo luyinkimbinkimbi futhi izindleko nazo ziphezulu.
Izinzuzo zama-air heater e-PTC zifaka phakathi ukumelana nokushisa okuphansi, ukushisa okusheshayo, i-voltage yokusebenza ebanzi, amandla azikhawulela wona, impilo ende, kanye nokuvuthwa okuphezulu komkhiqizo. Kodwa-ke, ukubi kwawo nakho kusobala, ikakhulukazi ukusetshenziswa kwamandla aphezulu, okunganciphisa ububanzi bezimoto zikagesi. Ngaphezu kwalokho, izinga lokushisa lobuso lama-air heater e-PTC liphezulu, okungafudumeza amapulasitiki azungezile futhi kukhiphe iphunga, ngakho-ke kufanele kuqashelwe ngokukhethekile lapho kuklanywa indawo yokufaka i-heater.
Ezinhlelweni zangempela, uhlelo lokulawula lwesifudumezi somoya se-PTC luzolungisa amandla esifudumezi ngokolwazi lwenzwa yokushisa emotweni ukuze kuhlangatshezwane nezidingo zenduduzo zabagibeli ngenkathi kunciphisa ukusetshenziswa kwamandla. Lolu hlobo lwesifudumezi lusetshenziswa kakhulu ezimotweni ezintsha zamandla, ikakhulukazi ezimweni lapho kudingeka khona ukushisa okusheshayo nokuphepha okuphezulu.
