Iyo PTCsisitimu yekudziyisa yemhepo inodziyainzira yakajairika yekudziisa mumotokari itsva dzinoshandisa simba, kunyanya mumotokari dzemagetsi chete. Sezvo mota dzemagetsi dzisina kupisa kwakashata kunogadzirwa neinjini dzinoshandisa simba remagetsi, dzinoda imwe nzira yakazvimirira yekudziyisa.mhinduro dzekupisaPTC ipfupiso ye "Positive Temperature Coefficient", iyo inoreva positive temperature coefficient. Kuramba kwechinhu ichi kunowedzera nekuwedzera kwetembiricha.
Nheyo yekushanda yePTC mhepo inodziyakushandisa hunhu uhwu hwezvinhu zvePTC kugadzira kupisa nekupfuudza magetsi kuburikidza nePTC element. Kana chinhu chePTC chapiswa, kukosha kwacho kwekudzivirira kuchawedzera nekuwedzera kwekupisa, nokudaro zvichideredza kuwedzera kwemagetsi, zvichiita kuti azvidzore uye kuchengetedza tembiricha inobuda nguva dzose. Chitofu ichi chine hunhu hwekuchengetedza simba, tembiricha isingachinji, kuchengetedzeka uye hupenyu hurefu hwebasa.
Mumotokari itsva dzinoshandisa simba, maPTC air heaters anowanzo kuve nezvinhu zvePTC, ma heat sinks uye ma housings.Chinhu chePTCndiyo chinhu chikuru chinobatsira pakudziisa; sinki yekupisa inoshandiswa kubvisa kupisa; imba yacho inodzivirira hita kudzivirira njodzi dzakadai sekuvhunduka kwemagetsi. PTC air heater inogona kudziisa mhepo zvakananga kana zvisina kunanga nekudziisa coolant. Nzira yekudziisa mhepo zvakananga ine chimiro chakareruka, asi panogona kunge paine njodzi dzekuchengetedza; nzira yekudziisa mhepo isina kunanga inoshandisa pombi yekudziisa coolant kupomba coolant ku radiator iri mumotokari, uye inoshandisa kupisa kubva ku coolant kudziisa mhepo. Nzira iyi inodzivirira kuunzwa kwema currents makuru uye ma voltages akakwira mumotokari uye ine kuchengetedzeka kwakanyanya, asi sisitimu yacho yakaoma uye mutengo wayo wakakwirawo.
Zvakanakira zvePTC air heater zvinosanganisira kusapisa zvakanyanya, kupisa nekukurumidza, voltage inoshanda zvakanyanya, simba rinozviganhurira, hupenyu hurefu, uye kukura kwechigadzirwa. Zvisinei, zvakaipa zvayo zviri pachenawo, kunyanya kushandiswa kwesimba rakawanda, izvo zvinogona kupfupisa huwandu hwemotokari dzemagetsi. Pamusoro pezvo, tembiricha yepamusoro yePTC heaters yakakwira, iyo inogona kupisa mapurasitiki akapoteredza uye kuburitsa hwema, saka kutarisisa kwakakosha kunofanirwa kupihwa pakugadzira nzvimbo yekuisa heater.
Mukushandiswa chaiko, sisitimu yekudzora yePTC air heater inogadzirisa simba reheater zvichienderana neruzivo rwesensor yekupisa mumotokari kuti igutse zvinodiwa nevafambi uku ichideredza kushandiswa kwesimba. Rudzi urwu rweheater ruri kushandiswa zvakanyanya mumotokari itsva dzine simba, kunyanya mumamiriro ezvinhu apo kupisa nekukurumidza uye kuchengetedzeka kwakanyanya kunodiwa.
