I-China PTC Coolant Heater Factory NF-Best EV PTC Coolant Heater

Phakathi kophuhliso lwamva nje kubuchwepheshe beemoto, kukho inkqubela phambili enkulu eyenziweyo kwicandelo leenkqubo zokufudumeza izithuthi zombane (i-EV). Ukufudumeza yinxalenye ebalulekileyo yayo nayiphi na imoto njengoko kuqinisekisa intuthuzelo nokhuseleko lomqhubi kunye nabakhweli, ingakumbi kwiimeko zemozulu ebandayo. Njengoko izithuthi zombane zithandwa ngakumbi, abavelisi bebesebenza ukuphuhlisa izisombululo zokufudumeza ezifanelekileyo ukuhlangabezana neemfuno ezizodwa zezithuthi zombane.

Enye yetekhnoloji yamva nje kweli candelo yii-heater ye-PTC yombane(I-Positive Temperature Coefficient). Ii-PTC heaters zenzelwe ukubonelela ngokufudumeza okukhawulezayo nokusebenzayo kwizithuthi zombane, ukuqinisekisa ukuba ikhabhathi yesithuthi ihlala ikwiqondo lobushushu elithozamisayo nokuba imozulu imbi kakhulu. Ezi heaters zisebenza ngombane kwaye zibonelela ngeenzuzo ezininzi kuneenkqubo zokufudumeza zemveli.

Olunye uphuhliso olutsha kwicandelo leenkqubo zokufudumeza iimoto ngombaneIsifudumezi se-HV esipholileyoLe nkqubo isebenzisa umatshini wamandla ombane ophezulu wesithuthi sombane ukubonelela ngokufudumeza ikhabhathi kunye nebhetri. Izifudumezi zokupholisa ezinombane ophezulu zisebenza kakuhle kwaye zinokunceda ukwandisa uluhlu lokuqhuba lwezithuthi zombane ngokunciphisa ukusetyenziswa kwamandla kwinkqubo yokufudumeza. Ezi zifudumezi zenzelwe ukusebenza nenkqubo yokuphola yebhetri yesithuthi sakho, ukuqinisekisa ukusebenza kakuhle nokusebenza kakuhle.

Kwizithuthi zombane, inkqubo yokufudumeza idlala indima ebalulekileyo ekusebenzeni kakuhle nasekusebenzeni kakuhle kwesithuthi. Iimoto zemveli zenjini yokutsha ngaphakathi zixhomekeke kubushushu obungafunwayo obuveliswa yinjini ukufudumeza ikhabhine. Nangona kunjalo, kwiimoto zombane, izisombululo zokufudumeza ezizezinye ziyafuneka ukuqinisekisa ukuba ikhabhine ihlala kubushushu obufanelekileyo ngaphandle kokuchaphazela uluhlu lwesithuthi.

Izifudumezi ze-PTC zombane zenzelwe ukuhlangabezana nalo mceli mngeni ngokubonelela ngokufudumeza okusebenzayo ngaphandle kokubeka uxinzelelo olongezelelweyo kwibhetri yesithuthi. Ezi zifudumezi zisebenzisa izinto ze-PTC ukuvelisa ubushushu, zivumela ulawulo oluchanekileyo lwenkqubo yokufudumeza. Oku kunciphisa amaxesha okufudumeza kwaye kunciphisa ukusetyenziswa kwamandla, okwenza kube sisisombululo esifanelekileyo kwizithuthi zombane.

Ngokufanayo, ii-heaters ze-coolant ezine-voltage ephezulu zenzelwe ukusebenza ngokungenamthungo nge-powertrain ye-high-voltage yezithuthi zombane. Ezi heaters zisebenzisa inkqubo yokupholisa yesithuthi ukudlulisa ubushushu kwikhabhini nakwibhetri, ukuqinisekisa ukuba inkqubo yokufudumeza isebenza kakuhle kwaye ayiphazamisi ukusebenza kwesithuthi iyonke. Ngokusebenzisa i-powertrain ye-high-voltage, ii-heaters ze-coolant ezine-voltage ephezulu zinokubonelela ngokufudumeza okukhawulezayo nokufanelekileyo ngelixa zinciphisa impembelelo kwi-mileage yesithuthi.

Njengoko imfuno yezithuthi zombane iqhubeka ikhula, abavelisi batyala imali ekuphuhliseni iinkqubo zokufudumeza eziphambili ukuhlangabezana neemfuno ezizodwa zezithuthi zombane. Ezi zinto zintsha zibonisa ukugxila okukhulayo kwishishini leemoto ekuzinzeni nasekusebenzeni kakuhle. Ngezifudumezi ze-PTC zombane kunyei-heater ye-PTC ene-voltage ephezulus, izithuthi zombane zinokubonelela ngamava okuqhuba akhululekileyo nasebenzayo, nto leyo eqhuba ngakumbi ukwamkelwa kwezithuthi zombane.

Ukudibanisa iinkqubo zokufudumeza eziphambili kwizithuthi zombane linyathelo elibalulekileyo ekuphuculeni ukusebenza ngokubanzi kunye nomtsalane wezithuthi zombane. Ngokusombulula imingeni yokufudumeza yezithuthi zombane, abavelisi benza inkqubela phambili enkulu ekwenzeni izithuthi zombane zibe yindlela efanelekileyo nenomtsalane kunezithuthi zemveli zokutsha ngaphakathi. Ngezi zinto zintsha, ikamva lezithuthi zombane libonakala liqaqambile kunangaphambili, libonelela ngezisombululo ezinomtsalane zothutho oluzinzileyo nolusebenzayo.
