Kwicandelo lobuchwepheshe beemoto obuphambili, ukudityaniswa kwezinto ezine-voltage ephezulu kudlala indima ebalulekileyo ekusebenzeni kakuhle nangokusebenza kakuhle. I-PTC (Positive Temperature Coefficient) coolant heater yenye yezinto ezitsala ingqalelo enkulu. Olu tshintsho lumangalisayo lutshintshe indlela izithuthi ezisebenzisa ngayo amandla, luqinisekisa amava okuqhuba ngokukhululekileyo nakwiimeko zemozulu ezimbi kakhulu. Kule blog, siza kuhlola amandla e-PTC coolant heaters kwaye sigqamise iingenelo ezizisayo, sigxile kwi-high voltage counterparts zazo, ezaziwa ngokuba zii-high voltage coolant heaters (HV).
Funda malungaIzifudumezi zePTC Coolant:
Izifudumezi ze-PTC coolant zizixhobo ezenzelwe ukufudumeza isifudumezi senjini kusetyenziswa umgaqo wokufudumeza ukumelana nombane. I-Positive temperature coefficient ibhekisa kwipropati yezinto ezithile apho ukumelana nombane kuyanda khona njengoko ubushushu busanda. Olu phawu luvumela isifudumezi se-PTC ukuba sizivumelanise neemfuno zobushushu ezahlukeneyo kwaye sizinzise ubushushu baso, ngelixa siqinisekisa ukuphuma kobushushu okuguquguqukayo nokuhlengahlengiswayo.
Yamkela iTekhnoloji yeVoltage ephezulu:
Izifudumezi ze-coolant ezine-voltage ephezulu, ezaziwa ngokuba zizifudumezi ze-coolant ezine-voltage ephezulu, zisebenzisa amandla enkqubo yoxinzelelo oluphezulu ukubonelela ngokusebenza okuphezulu kunye nokusebenza kakuhle kwamandla kunezinye zemveli ezisebenzisa umbane ophantsi. Izifudumezi ze-coolant ezine-voltage ephezulu ziyakwazi ukusebenza ngaphezulu kwe-300 volts, zibonelela ngombane ophezulu kunye namaxesha okuphendula aphuculweyo, nto leyo ezenza zilungele izithuthi zanamhlanje ezineemfuno zamandla ezandayo.
Ukusebenza kakuhle kwamandla kunye neenzuzo zokusingqongileyo:
Iisifudumezi sokupholisa esine-voltage ephezuluYenzelwe ukwandisa ukonga amandla nokunciphisa ukusetyenziswa kwamandla kwesithuthi ngokubanzi. Ngokudlulisela ubushushu ngokukhawuleza nangokufanelekileyo, zinceda ukunciphisa amaxesha okufudumeza injini, ukunciphisa ukusetyenziswa kwepetroli nokunciphisa ukukhutshwa komoya okuyingozi. Ukongeza, ezi zifudumezi zivumela ukusasazwa kobushushu ngokufanelekileyo kuyo yonke ikhabhinethi, ziqinisekisa intuthuzelo yabakhweli ngelixa zinciphisa inkunkuma yamandla.
Imisebenzi eguquguqukayo:
Enye yezona zinto zibalaseleyo zezifudumezi ze-PTC ezipholileyo, kuqukaIzifudumezi ze-HV coolant, kukukwazi kwazo ukubonelela ngemisebenzi eyahlukeneyo yokusebenza. Ezi heater zinokudityaniswa neendlela ezahlukeneyo zokucwangcisa amandla, kubandakanya iinjini zombane, ezixutyiweyo neziqhelekileyo, kwiintlobo ngeentlobo zezithuthi kunye neemodeli. Ukuguquguquka kweheater yokupholisa ene-voltage ephezulu kufikelela ekuhambelaneni nemithombo yamandla eyahlukeneyo, kubandakanya amandla ebhetri, iijenereyitha ezikwibhodi, kunye neenkqubo zamandla avuselelekayo, nto leyo ephucula ngakumbi amandla ayo kwiintlobo ngeentlobo zezicelo.
Ukuthembeka noKhuseleko:
Ukhuseleko lolona phawu luphambili kuzo zonke izinto zeemoto, kwaye ii-PTC coolant heaters ziyabalasela kule nkalo. Ngeenkqubo zolawulo ezidibeneyo kunye neendlela zokubeka esweni eziphambili, ziqinisekisa ukusebenza ngokukhuselekileyo nangokufanelekileyo. Ukongeza, i-high-voltage coolant heater ixhotyiswe ngamanyathelo okukhusela afana nolawulo lwamandla ombane, i-voltage kunye nobushushu ukuthintela ukugqithisa okanye ukungaphumeleli okunokwenzeka. Ezi mpawu zokhuseleko zinceda ukuphucula ukuthembeka kunye nobomi be-heater ngelixa zibonelela ngoxolo lwengqondo kubanini bezithuthi kunye nabavelisi.
Indima yezifudumezi ze-PTC ezipholileyo ekufakeni umbane:
Njengoko kukho utshintsho olukhulu ekufakeni umbane kwishishini leemoto, ii-PTC coolant heaters, ingakumbi ii-high voltage coolant heaters, ziyinxalenye ebalulekileyo. Zidlala indima ebalulekileyo ekuxhaseni utshintsho oluvela kwiinjini eziqhelekileyo zokutsha zangaphakathi ukuya kwiimoto zombane neze-hybrid, zibonelela ngokufudumeza okufunekayo ngaphandle kokuphazamisa ukusebenza kakuhle kwamandla. Ngokudibanisa ii-PTC coolant heaters kumaqonga ombane okanye e-hybrid, abavelisi banokuphucula ukusetyenziswa kwamandla kwaye baphucule amava okuqhuba ngokubanzi.
ukuququmbela:
Ukuqaliswa kwezifudumezi ze-PTC ezipholileyo, ingakumbi izifudumezi ze-HV ezipholileyo, kuye kwaguqula indlela izithuthi ezilawula ngayo ubushushu, kuqinisekisa ukusebenza kakuhle kwamandla kunye nokuphucula intuthuzelo yabakhweli. Ngenxa yamandla azo amangalisayo, ukuguquguquka kunye neempawu zokhuseleko, izifudumezi ze-high voltage ezipholileyo zikamva leenkqubo zokufudumeza iimoto. Njengoko ishishini liqhubeka likhula, ukwamkelwa kwetekhnoloji ye-high voltage akuyomfuneko nje kuphela, kodwa kukwayinyathelo eliya ekuhambeleni phambili okuzinzileyo nokusingqongileyo.
