Emkhakheni wobuchwepheshe bezimoto obuthuthukisiwe, ukuhlanganiswa kwezingxenye ze-high-voltage kudlala indima ebalulekile ekusebenzeni kahle kanye nokusebenza kahle. I-PTC (Positive Temperature Coefficient) coolant heater ingenye yezingxenye ezithola ukunakwa okukhulu. Lokhu kusungulwa okumangalisayo kwaguqula indlela izimoto ezisebenzisa ngayo amandla, kuqinisekisa isipiliyoni sokushayela esikhululekile ngisho nasezimweni zezulu ezimbi kakhulu. Kule bhulogi, sizohlola amakhono ama-PTC coolant heater futhi siqokomise izinzuzo ezilethayo, sigxile kuma-high voltage afana nawo, aziwa kakhulu ngokuthi ama-high voltage coolant heater (HV).
Funda mayelanaIzifudumezi Zokupholisa ze-PTC:
Ama-heater e-PTC coolant amadivayisi aklanyelwe ukufudumeza i-coolant yenjini kusetshenziswa isimiso sokushisa ukumelana nogesi. I-coefficient yokushisa elungile ibhekisela kumpahla yezinto ezithile lapho ukumelana kukagesi kukhuphuka khona ngokushisa okwandayo. Lesi sici sivumela i-heater ye-PTC ukuthi ivumelane nezidingo zokushisa ezahlukahlukene futhi izinzise izinga lokushisa layo, ngenkathi iqinisekisa ukuphuma kokushisa okuhambisanayo nokulungisekayo.
Yamukela Ubuchwepheshe Be-High Voltage:
Ama-heater asebenzisa ukupholisa ane-voltage ephezulu, aziwa nangokuthi ama-heater asebenzisa ukupholisa ane-voltage ephezulu, asebenzisa amandla esistimu enomfutho ophezulu ukuze alethe ukusebenza okuhle kanye nokusebenza kahle kwamandla kunezinye zendabuko zama-heater asebenzisa ugesi ophansi. Ama-heater asebenzisa ukupholisa ane-voltage ephezulu ayakwazi ukusebenza ngama-volts angaphezu kwama-300, ahlinzeka ngokukhipha amandla okuphezulu kanye nezikhathi zokuphendula ezithuthukisiwe, okwenza kube kuhle kakhulu ezimotweni zesimanje ezinezidingo zamandla ezandayo.
Ukusetshenziswa kahle kwamandla kanye nezinzuzo zemvelo:
Iisifudumezi sokupholisa esine-voltage ephezuluiklanyelwe ukwandisa ukusebenza kahle kwamandla nokunciphisa ukusetshenziswa kwamandla kwemoto iyonke. Ngokudlulisa ukushisa ngokushesha nangendlela efanele, kusiza ukunciphisa izikhathi zokufudumeza injini, ukunciphisa ukusetshenziswa kukaphethiloli nokunciphisa ukukhishwa komoya okuyingozi. Ngaphezu kwalokho, lawa ma-heater avumela ukusatshalaliswa kokushisa okuphumelelayo kuyo yonke ikabhini, okuqinisekisa induduzo yabagibeli ngenkathi kunciphisa imfucuza yamandla.
Imisebenzi eguquguqukayo:
Esinye sezici ezivelele zama-heater e-PTC coolant, okuhlanganisaIzifudumezi ze-HV coolant, yikhono lazo lokuhlinzeka ngemisebenzi ehlukahlukene yokusebenza. Lawa ma-heater angahlanganiswa nokulungiselelwa okuhlukahlukene kwe-powertrain, okuhlanganisa izinjini zikagesi, ezihlanganisiwe nezivamile, ngezinhlobo eziningi zezimoto namamodeli. Ukuguquguquka kwe-heater yokupholisa enamandla aphezulu kudlulela ekuvumelaneni nemithombo yamandla ehlukene, okuhlanganisa amandla ebhethri, ama-generator asebhodini, kanye nezinhlelo zamandla avuselelekayo, okuthuthukisa kakhulu amandla ayo ezinhlelo zokusebenza eziningi.
Ukuthembeka Nokuphepha:
Ukuphepha kuyinto ebaluleke kakhulu kuzo zonke izingxenye zezimoto, futhi ama-heater e-PTC coolant ahamba phambili kulokhu. Ngezinhlelo zokulawula ezihlanganisiwe kanye nezindlela zokuqapha ezithuthukisiwe, aqinisekisa ukusebenza okuphephile nokusebenza kahle. Ngaphezu kwalokho, i-heater ye-coolant enamandla aphezulu ifakwe izindlela zokuvikela ezifana nokulawula ugesi, ugesi kanye nokushisa ukuze kuvinjelwe ukushisa ngokweqile noma ukwehluleka okungenzeka. Lezi zici zokuphepha zisiza ekuthuthukiseni ukuthembeka okuphelele kanye nokuphila kwesikhathi se-heater ngenkathi zinikeza ukuthula kwengqondo kubanikazi bezimoto nabakhiqizi.
Indima yama-heater e-PTC coolant ekufakweni kukagesi:
Njengoba sekushintshe kakhulu ekufakweni kukagesi embonini yezimoto, ama-heater e-PTC coolant, ikakhulukazi ama-heater e-high voltage coolant, ayisici esibalulekile. Adlala indima ebalulekile ekusekeleni ukuguquka kusuka ezinjinini ezivamile zokushisa zangaphakathi kuya ezimotweni zikagesi neze-hybrid, enikeza ukushisa okudingekayo ngaphandle kokuphazamisa ukusebenza kahle kwamandla. Ngokuhlanganisa ama-heater e-PTC coolant kumapulatifomu kagesi noma e-hybrid, abakhiqizi bangenza ngcono ukusetshenziswa kwamandla futhi bathuthukise ulwazi lokushayela oluphelele.
Ekuphetheni:
Ukuqaliswa kwezifudumezi ze-PTC ezipholile, ikakhulukazi izifudumezi ze-HV ezipholile, kushintshe indlela izimoto ezilawula ngayo izinga lokushisa, kuqinisekisa ukusebenza kahle kwamandla kanye nokuthuthukisa induduzo yabagibeli. Ngamakhono azo amangalisayo kagesi, ukuzivumelanisa nezimo kanye nezici zokuphepha, izifudumezi ze-high voltage coolant ziyikusasa lezinhlelo zokushisa izimoto. Njengoba imboni iqhubeka nokukhula, ukwamukelwa kobuchwepheshe be-high voltage akudingeki nje kuphela, kodwa futhi kuyisinyathelo esibheke ekuhambeni okusimeme nokunobungani nemvelo.
