Kwintsimi yetekhnoloji yemoto ephucukileyo, ukudityaniswa kwamacandelo aphezulu ombane kudlala indima ebalulekileyo ekusebenzeni kakuhle kunye nokusebenza kakuhle.Isifudumezi esipholisayo se-PTC (Positive Temperature Coefficient) sesinye samacandelo afumana ingqwalasela enkulu.Olu tshintsho lumangalisayo luye lwayiguqula indlela izithuthi ezisebenzisa ngayo amandla, zaqinisekisa amava okuqhuba kakuhle nakwimozulu embi.Kule bhlog, siza kuphonononga ubunakho bezifudumezi zokupholisa ze-PTC kwaye siqaqambise izibonelelo abazizisayo, sijolise koogxa babo bamandla ombane aphezulu, aziwa ngokuba zizifudumezi zombane ophezulu wombane (HV).
Funda malungaIzifudumezi eziPholisayo zePTC:
Izifudumezi zokupholisa ze-PTC zizixhobo eziyilelwe ukufudumeza isixhasi se-injini kusetyenziswa umthetho-siseko wokuxhathisa umbane.I-coefficient yeqondo lokushisa elihle libhekisela kwipropati yezinto ezithile ukuba ukunyuka kombane kwanda ngokunyuka kweqondo lokushisa.Eli nqaku livumela isifudumezi se-PTC ukuba silungelelanise iimfuno zobushushu ezahlukeneyo kwaye zizinzise ubushushu baso, ngelixa siqinisekisa ubushushu obungaguqukiyo kunye nohlengahlengiso.
Yamkela iTekhnoloji yoMbane oPhezulu:
Izifudumezi zokupholisa ezinevoltage ephezulu, ezikwaziwa ngokuba zizifudumezi ezinevoltage eziphezulu zokupholisa, zisebenzisa amandla enkqubo yoxinzelelo oluphezulu ukuhambisa ukusebenza okuphezulu kunye nokusebenza kakuhle kwamandla kunezinye zazo zemveli ezinombane ophantsi.Izifudumezi ezipholisa amandla ombane aphezulu ziyakwazi ukusebenza ngaphezulu kwe-300 volts, zibonelela ngemveliso yamandla aphezulu kunye namaxesha okuphendula aphuculweyo, zizenza zilungele izithuthi zale mihla ezinemfuno zamandla ezongeziweyo.
Ukusebenza kakuhle kwamandla kunye neenzuzo zokusingqongileyo:
Iisifudumezi sokupholisa esinevoltage ephezuluyenzelwe ukwandisa ukusebenza kakuhle kwamandla kunye nokunciphisa ukusetyenziswa kwamandla ngokubanzi kwesithuthi.Ngokuhambisa ubushushu ngokukhawuleza nangokufanelekileyo, banceda ukunciphisa amaxesha okufudumala kwe-injini, ukunciphisa ukusetyenziswa kwepetroli kunye nokunciphisa ukukhutshwa okuyingozi.Ukongeza, ezi zifudumezi zivumela ukuhanjiswa kobushushu ngendlela eyiyo kuyo yonke i-cabin, iqinisekisa ukukhululeka kwabakhweli ngelixa inciphisa inkcitho yamandla.
Imisebenzi ebhetyebhetye:
Enye yeempawu ezibalaseleyo zePTC zokufudumeza okupholisayo, kubandakanywaIzifudumezi zokupholisa zeHV, kukukwazi kwabo ukubonelela ngemisebenzi eyahlukeneyo yokusebenza.Ezi zifudumezi zinokudibaniswa kunye nokucwangciswa kweendlela ezahlukeneyo zombane, kubandakanywa umbane, i-hybridi kunye neenjini eziqhelekileyo, kwiindidi ezahlukeneyo zezithuthi kunye neemodeli.Ukuguquguquka kwesifudumezi esinevoltage ephezulu kwandisa ukuhambelana nemithombo eyahlukeneyo yamandla, kubandakanywa amandla ebhetri, iijenereyitha ezisebhodini, kunye neenkqubo zamandla ahlaziyekayo, ngakumbi ukunyusa amandla aso kuluhlu olubanzi lwezicelo.
Ukuthembeka kunye noKhuseleko:
Ukhuseleko yeyona nto iqwalaselwayo kuwo onke amacandelo eemoto, kwaye izifudumezi zokupholisa ze-PTC ziyagqwesa kulo mba.Ngeenkqubo ezidibeneyo zokulawula kunye neendlela eziphambili zokubeka iliso, ziqinisekisa ukusebenza okukhuselekileyo nokusebenzayo.Ukongeza, i-heater ye-high-voltage epholileyo ixhotyiswe ngamanyathelo okukhusela njengangoku, i-voltage kunye nokulawula ubushushu ukuthintela ukutshisa okanye ukusilela okunokwenzeka.Ezi mpawu zokhuseleko zinceda ekuphuculeni ukuthembeka okupheleleyo kunye nexesha lokuphila kwesifudumezi ngelixa zibonelela ngoxolo lwengqondo kubanini bezithuthi kunye nabavelisi.
Indima yezifudumezi zokupholisa ze-PTC ekufakeni umbane:
Ngotshintsho olukhulu olubhekiselele ekufakeni umbane kushishino lweemoto, izifudumezi zokupholisa ze-PTC, ingakumbi izifudumezi zamandla ombane aphezulu zokupholisa, ziyinxalenye eyimfuneko.Badlala indima ebalulekileyo ekuxhaseni utshintsho olusuka kwiinjini eziqhelekileyo zokutsha zangaphakathi ukuya kwiimoto zombane kunye ne-hybrid, ukubonelela ngokufudumeza okufunekayo ngaphandle kokuphazamisa ukusebenza kakuhle kwamandla.Ngokudibanisa izifudumezi ezipholisayo ze-PTC kumaqonga ombane okanye axubeneyo, abavelisi banokwandisa ukusetyenziswa kwamandla kwaye baphucule amava okuqhuba ngokubanzi.
ukuququmbela:
Ukuphunyezwa kwezifudumezi zokupholisa ze-PTC, ngakumbi izifudumezi zokupholisa ze-HV, kuyitshintshe indlela izithuthi ezilawula ngayo ubushushu, ukuqinisekisa ukusebenza kakuhle kwamandla kunye nokuphucula ukukhululeka kwabakhweli.Ngobuchule babo bamandla achukumisayo, ukuguquguquka kunye neempawu zokhuseleko, izifudumezi zombane ophakamileyo wokupholisa zilikamva leenkqubo zokufudumeza iimoto.Njengoko ishishini liqhubeka likhula, ukwamkelwa kobuchwephesha be-voltage ephezulu ayimfuneko kuphela, kodwa kunye nenyathelo eliya kuhambo oluzinzileyo kunye nokusingqongileyo.
