Njengoba ukuphathwa kokushisa kwamabhethri ezimoto zamandla amasha kuthuthuka, izindlela ezimbili ezinkulu zobuchwepheshe zibusa imakethe:Isifudumezi se-PTCama-heater efilimu amancane/aqinile. Ngayinye inikeza izimiso ezihlukile kanye nezinzuzo zokusebenza. I-Hebei Nanfeng Automobile Equipment (Group) Co., Ltd, umhlinzeki ohamba phambili waseShayina wezingxenye ze-EV kanye nomhlinzeki oqokiwe wezimoto zempi, inikeza izixazululo ze-PTC water heater ezivuthiwe kanye nama-heater asezingeni eliphezulu asekelwe kufilimu.
I-HVCHUmehluko Wezimiso Zokusebenza Nokuklama
Ama-heater e-PTC athembele kuma-ceramics okushisa amahle. Njengoba izinga lokushisa likhuphuka, ukumelana kuyanda kakhulu, kufinyelela izinga lokushisa elizikhawulelayo kanye nokuvikelwa kokushisa ngokweqile. Lo mthethonqubo ongenzi lutho unikeza ukuphepha kodwa ukhawulela ukulawula ngokunemba kanye nesivinini sokuphendula.
Ngokuphambene nalokho, ama-heater efilimu amancane/aqinile asebenzisa i-foil yensimbi eqoshiwe noma amasekethe efilimu amakhulu – uhlelo oluhlanzekile lokumelana oluguqula ugesi ube ukushisa ngokusebenza kahle kakhulu. Avumela ukulawula okusebenzayo nokunembile nge-PWM, ukwakhiwa okuqinile kakhulu (okuncane njengo-0.3-1.5 mm), kanye nokuzivumelanisa kwemvelo namapulatifomu angu-800V – inzuzo eyinhloko ngaphezu kobuchwepheshe be-PTC.
Isifudumezi Sokupholisa Se-HVUkuqhathaniswa Kokusebenza
| I-Metric | Isifudumezi se-PTC | Isifudumezi Sefilimu Esincane/Esiqinile |
|---|---|---|
| Ukusebenza kahle kwamandla | <90% | 95‑97% |
| I-Inrush yamanje | Yethula | Akukho |
| Ukuqina kwamandla | Ukwehla ngokushisa kwe-coolant | Izinzile kulo lonke uhla |
Isipholisi Se-Voltage EphakemeIzicelo Ze-Heater
Ubuchwepheshe be-PTC buhlala buyindlela ethandwayo ngenxa yokuvuthwa kwayo kanye nezindleko eziphansi, ezisetshenziswa kabanzi ezinhlelweni zokushisa ze-PTC coolant kanye ne-cabin ze-BEVs, HEVs, kanye ne-FCEVs.
Ama-heater efilimu asebenza njengezixazululo ze-heater kagesi esebenza kahle kakhulu, ikakhulukazi ekushiseni kwebhethri lepulatifomu enamandla aphezulu (400V/800V). Aqinisekisa ukufudumala kwebhethri ngokushesha emazingeni okushisa aphansi, okwenza kube ngcono ukusebenza kokushaja kanye nokuphila kwebhethri.
Iminikelo Ephelele KaNanfeng
Isebenzisa amafektri ayisithupha kanye nobuchwepheshe beminyaka eminingi, i-Nanfeng inikeza kokubili ama-heater e-PTC athembekile kanye nama-heater efilimu amancane/aqinile athuthukisiwe - kufaka phakathi i-heater epholile ene-voltage ephezulu kanye ne-heater epholile ye-hv. Kungakhathaliseki ukuthi okubaluleke kakhulu kuwe ukusebenza kahle kwezindleko noma ukusebenza kahle kwamapulatifomu angu-800V, i-Nanfeng inikeza ikhambi elilungiselelwe wena.
Isifudumezi Sokupholisa SikagesiIsifinyezo
Khetha i-PTC uma izindleko zibalulekile ezimotweni zokuqala noma ezingama-400V. Khetha ama-heater efilimu amancane/aqinile uma uphishekela ukusebenza kahle kakhulu, ukwakheka okulula, impendulo yokushisa okusheshayo, noma ukulungela i-800V. Ukuze uthole ulwazi olwengeziwe ngephothifoliyo ye-heater yokupholisa kagesi yaseNanfeng, sicela usithinte ngqo.
