Sezvo kufambira mberi kwekushandiswa kwemafuta matsva emotokari, nzira mbiri huru dzetekinoroji dziri kutonga pamusika:PTC hitas uye mafirita matete/makobvu. Imwe neimwe ine misimboti yakasiyana uye zvakanakira mashandiro ayo. Hebei Nanfeng Automobile Equipment (Group) Co., Ltd, mutengesi anotungamira wekuChina wezvinhu zveEV uye mutengesi akasarudzwa wemotokari dzehondo, inopa mhinduro dzePTC dzemvura dzakakura uye mafirita epamusoro akagadzirwa nefirimu.
HVCHKusiyana Kwekushanda & Kugadzira
Maheater ePTC anovimba ne positive temperature coefficient ceramics. Sezvo tembiricha ichikwira, resistance inowedzera zvakanyanya, zvichiita kuti tembiricha izvidzikire uye dziviriro yekupisa zvakanyanya. Mutemo uyu unopa kuchengetedzeka asi unoderedza kutonga kwakarurama uye kumhanya kwekupindura.
Kusiyana neizvi, ma "thin/gobvu film heaters" anoshandisa foil yesimbi yakachekwa kana ma "good-film circuits" - sisitimu yakachena inoshandura magetsi kuita kupisa nekushanda kwakanyanya. Anobvumira kudzora kunoshanda uye kwakanyatsojeka kuburikidza nePWM, kuvaka kwakasimba (kwakatetepa se 0.3-1.5 mm), uye kugadziriswa kwechisikigo kumapuratifomu e800V - mukana mukuru pane tekinoroji yePTC.

Chinotonhodza cheMagetsi AkawandaMaitiro eHeta
Tekinoroji yePTC inoramba iri sarudzo huru nekuda kwekukura kwayo uye mutengo wayo wakaderera, inoshandiswa zvakanyanya muPTC coolant heater uye cabin heating systems dzeBEVs, HEVs, uye FCEVs.
Mafiramu ekupisa mafirimu anoshanda senzira dzemagetsi dzinotonhodza dzinoshanda zvakanaka, kunyanya pakupisa mabhatiri ane voltage yakawanda (400V/800V). Anovimbisa kuti bhatiri rinodziya nekukurumidza mukupisa kwakaderera, zvichiita kuti bhatiri rishande zvakanaka uye rigare kwenguva refu.
Zvipo Zvakazara zveNanfeng
Ichishandisa mafekitori matanhatu nehunyanzvi hwemakumi emakore, Nanfeng inopa maheater ePTC akavimbika uye maheater epamusoro-soro akatetepa/akakora - kusanganisira heater inotonhorera ine voltage yakawanda uye heater inotonhorera yehv. Kunyangwe iwe uchinyanya kukosha kuri kushanda zvakanaka kana kushanda zvakanaka kwemapuratifomu e800V, Nanfeng inopa mhinduro yakagadzirirwa iwe.
