Ngezimoto zikagesi ezimsulwa, Uvelaphi Umthombo Wokushisa Wohlelo Lokushisisa?

Isistimu yokushisa imoto yamafutha

Okokuqala, ake sibuyekeze umthombo wokushisa wesistimu yokushisisa yemoto kaphethiloli.

Ukusebenza kahle okushisayo kwenjini yemoto kuphansi kakhulu, cishe kuphela u-30% -40% wamandla akhiqizwa ukusha aguqulwa abe amandla omshini wemoto, kanti amanye athathwa yigesi epholile kanye ne-exhaust.Amandla okushisa athathwa yi-coolant abala cishe u-25-30% wokushisa kokuvutha.
Isistimu yokushisisa yemoto kaphethiloli yendabuko iwukuqondisa isipholile esisesistimu yokupholisa injini ukuya endaweni yokushisa komoya/yamanzi kukhebhu.Lapho umoya ugeleza kurediyetha, amanzi asezingeni eliphezulu angadlulisela kalula ukushisa emoyeni, ngaleyo ndlela aphephule Umoya ongena eklabishi umoya ofudumele.

Isistimu yokushisisa yamandla entsha

Uma ucabanga ngezimoto zikagesi, kungase kube lula ngawo wonke umuntu ukuthi acabange ukuthi uhlelo lwe-heater olusebenzisa ngokuqondile intambo yokumelana nokushisa umoya alwanele.Ngokombono, kungenzeka ngokuphelele, kodwa cishe awekho amasistimu okushisa okushisa ezimoto zikagesi.Isizathu siwukuthi i-resistance wire idla ugesi omningi..

Njengamanje, izigaba ezintshaamasistimu okushisa amandlaikakhulukazi izigaba ezimbili, eyodwa i-PTC yokufudumeza, enye ubuchwepheshe bepompo yokushisa, futhi ukushisa kwe-PTC kuhlukanisweI-PTC yomoya kanye ne-PTC epholile.

I-heater ye-PTC

Umgomo wokushisisa wesistimu yokushisa yohlobo lwe-PTC ilula futhi kulula ukuyiqonda.Kufana nesistimu yokushisa yocingo yokumelana, ethembele kumanje ukukhiqiza ukushisa ngokusebenzisa ukumelana.Umehluko kuphela yizinto ezibonakalayo zokumelana.Intambo yokumelana iwucingo lwensimbi olujwayelekile olungamelana kakhulu, kanti i-PTC esetshenziswa ezimotweni zikagesi ezihlanzekile iyi-semiconductor thermistor.I-PTC isifinyezo se-Positive Temperature Coefficient.Inani lokumelana nalo lizokhula.Lesi sici sinquma ukuthi ngaphansi kwesimo se-voltage eqhubekayo, i-heater ye-PTC ishisa ngokushesha lapho izinga lokushisa liphansi, futhi lapho izinga lokushisa likhuphuka, inani lokumelana liba likhulu, lamanje liba lincane, futhi i-PTC idla amandla amancane.Ukugcina izinga lokushisa lingashintshi kuzokonga ugesi uma kuqhathaniswa nokushisisa kwezintambo eziqinile.

Yilezi zinzuzo ze-PTC eziye zamukelwa kabanzi yizimoto zikagesi ezihlanzekile (ikakhulukazi amamodeli aphansi).

Ukushisa kwe-PTC kuhlukanisweI-heater epholile ye-PTC kanye ne-air heater.

I-heater yamanzi ye-PTCkuvame ukuhlanganiswa namanzi okupholisa imoto.Lapho izimoto zikagesi zigijima nge-motor egijima, injini nayo izoshisa.Ngale ndlela, uhlelo lokushisisa lungasebenzisa ingxenye yenjini ukuze lushise ngaphambili ngesikhathi sokushayela, futhi lungonga nogesi.I-EV high voltage coolant heater.
