Njengoko ulawulo olutsha lobushushu bebhetri yesithuthi samandla lutshintsha, iindlela ezimbini eziphambili zobuchwepheshe zilawula imarike:Isifudumezi se-PTCIzifudumezi zefilimu ezincinci/ezityebileyo. Nganye inemigaqo eyahlukileyo kunye neenzuzo zokusebenza. I-Hebei Nanfeng Automobile Equipment (Group) Co., Ltd, umthengisi ophambili waseTshayina wezixhobo ze-EV kunye nomthengisi otyunjiweyo wezithuthi zomkhosi, ibonelela ngezisombululo zesifudumezi samanzi se-PTC esivuthiweyo kunye nezifudumezi ezisekelwe kwifilimu eziphambili.
I-HVCHUmahluko kwiMigaqo yokusebenza kunye noYilo
Ii-PTC heaters zixhomekeke kwi-ceramics ezibonisa ubushushu obuhle. Njengoko ubushushu bunyuka, ukumelana kuyanda kakhulu, nto leyo efikelela kubushushu obuzithintelayo kunye nokhuseleko olugqithisileyo. Lo mgaqo ungenamsebenzi ubonelela ngokhuseleko kodwa uthintela ukuchaneka kolawulo kunye nesantya sokuphendula.
Ngokwahlukileyo koko, izifudumezi zefilimu ezibhityileyo/ezityebileyo zisebenzisa ifoyile yesinyithi eqoshiweyo okanye iisekethe zefilimu etyebileyo – inkqubo yokumelana ecocekileyo eguqula umbane ube bubushushu ngokusebenza kakuhle. Zivumela ulawulo olusebenzayo noluchanekileyo nge-PWM, ulwakhiwo oluncinci kakhulu (oluncinci njenge-0.3-1.5 mm), kunye nokuziqhelanisa ngokwendalo namaqonga e-800V – inzuzo ephambili kunetekhnoloji ye-PTC.

| I-Metric | Isifudumezi sePTC | Isifudumezi seFilimu esibhityileyo/esityebileyo |
|---|---|---|
| Ukusebenza kakuhle kwamandla | <90% | 95‑97% |
| Umsinga wangoku | Okwangoku | Akukho nanye |
| Uzinzo lwamandla | Amathontsi anobushushu obupholileyo | Izinzile kuluhlu olupheleleyo |
Isipholisi seVolthi ephezuluIzicelo zeHeater
Itekhnoloji ye-PTC iseyeyona ndlela iphambili yokukhetha ngenxa yokuvuthwa kwayo kunye nexabiso layo eliphantsi, esetyenziswa kakhulu kwiinkqubo zokufudumeza ii-coolant ze-ptc kunye neenkqubo zokufudumeza iikhabhini ze-BEVs, ii-HEVs, kunye nee-FCEVs.
Izifudumezi zefilimu zisebenza njengezisombululo zesifudumezi sombane esisebenza kakuhle kakhulu, ingakumbi ekufudumaleni kwebhetri yeqonga le-voltage ephezulu (400V/800V). Ziqinisekisa ukufudumeza kwebhetri ngokukhawuleza kumaqondo obushushu aphantsi, nto leyo ephucula ukusebenza kokutshaja kunye nobomi bebhetri.
Iminikelo epheleleyo kaNanfeng
Isebenzisa iifektri ezintandathu kunye namava eminyaka emininzi, iNanfeng ibonelela ngee-heater ze-PTC ezithembekileyo kunye nee-heaters zefilimu ezithambileyo/ezingqindilili eziphambili - kubandakanya i-heater ye-coolant ene-voltage ephezulu kunye ne-heater ye-coolant ene-hv. Nokuba eyona nto iphambili kuwe kukusebenza kakuhle kweendleko okanye ukusebenza kakuhle kwamaqonga e-800V, iNanfeng inika isisombululo esilungiselelwe wena.
Isifudumezi seSipholisi soMbaneIsishwankathelo
Khetha i-PTC xa ixabiso libalulekile kwizithuthi zokuqala okanye ezingama-400V. Khetha izifudumezi zefilimu ezincinci/ezityebileyo xa ulandela ukusebenza kakuhle kakhulu, uyilo olukhaphukhaphu, impendulo yokufudumeza ngokukhawuleza, okanye ukulungela i-800V. Ukuze ufumane ulwazi oluthe kratya malunga nepotifoliyo yesifudumezi sokupholisa umbane saseNanfeng, nceda unxibelelane nathi ngokuthe ngqo.
