Ngokugxila kukhuseleko lokusingqongileyo, uphuhliso lwezithuthi zombane lufumene ingqalelo enkulu kwihlabathi liphela kwaye lungena kwimarike yeemoto. Iimoto ezineenjini zokutsha zangaphakathi zisebenzisa ubushushu obuchithwe yinjini ukufudumeza, zifuna izixhobo ezongezelelweyo njengomthombo wazo ophambili wokufudumeza.Izifudumezi zeHigh Voltage Positive Temperature Coefficient (PTC)Ezikwaziyo ukufikelela kumandla okufudumeza afunekayo, ukusebenza kakuhle, kunye nokuthembeka kuthathwa njengolona khetho lufanelekileyo. Ii-heaters ze-Positive temperature coefficient (PTC) zizisa ukusebenza kakuhle kunye nokhuseleko kwiinkqubo zokufudumeza ze-EV. Into yokufudumeza engaphakathi kwi-aIsifudumezi se-PTCine-coefficient yobushushu obuhle kwaye ukumelana kwayo kuyakhula kunye nobushushu. Xa amandla eqala ukusetyenziswa kwi-PTC heating element ebandayo, inokumelana okuphantsi kwaye itsala inani elikhulu lamandla ombane. Njengoko ishushu, ukumelana kuyanda kwaye ukutsalwa kwamandla ombane kuyancipha. Oku kwenza i-PTC heater ikhuseleke kwaye isebenze kakuhle; i-PTC heater iyayeka ukutsala amandla ombane ukuba ishushu kakhulu kwaye itsala kuphela amandla ombane afunekayo ukugcina ubushushu. I-PTC heater ikwatshisa ngokukhawuleza kune-element yesiqhelo, njengoko itsala amandla ombane aphezulu xa kubanda.
Inxalenye yeheaterIsifudumezi somoya se-PTCIndibano ikwinxalenye esezantsi yeheater, kusetyenziswa iimpawu zephepha le-PTC ukufudumeza. Iheater inikwa amandla yi-voltage ephezulu, iphepha le-PTC livelisa ubushushu, ubushushu budluliselwa kwi-heat sink aluminium strip, kwaye emva koko ifeni ye-airbox ivuthela phezu komphezulu weheater, isusa ubushushu kwaye ikhuphe umoya ofudumeleyo. Isakhiwo esincinci seheater ye-PTC, uyilo olufanelekileyo, ukusetyenziswa kakuhle kwesithuba seheater, kwaye kuyilo lweheater kufuneka kuqwalaselwe inkqubo yokhuseleko, ukungangeni manzi, ukuqinisekisa ukuba iheater isebenza ngokuqhelekileyo.Isifudumezi sombane se-PTCIsetyenziswa kakhulu kwiimoto zombane namhlanje ukunyibilikisa iqhwa nokufudumeza umoya. Xa ithelekiswa neheater yendabuko, ikhuselekile kwaye ithembekile ngakumbi kuba i-PTC element ezilawulayo ayiyi konakala ngaphandle kokuhamba komoya.
Indibano yesifudumezi somoya se-NF PTC isebenzisa isakhiwo esinye, idibanisa isilawuli kunye nesifudumezi se-PTC kwenye, imveliso incinci ngobukhulu, ilula ngobunzima kwaye kulula ukuyifaka.
