Iingenelo zePTC Coolant Heaters kwiiMoto High Voltage Systems

Njengoko iteknoloji yeemoto iqhubeka ihambela phambili, imfuneko yeenkqubo zokufudumeza ezisebenzayo nezithembekileyo kwizithuthi ezine-voltage ephezulu iye yaba yinto ebaluleke ngakumbi. I-PTC (positive temperature coefficient) coolant heater, eyaziwa ngokuba yi-automotive high-voltage coolant heater (I-HVCH), yinto entsha efumana udumo kwishishini leemoto. Kule blog, siza kuhlola iingenelo zezifudumezi ze-PTC ezipholileyo kwiinkqubo zeemoto ezine-voltage ephezulu kunye nesizathu sokuba zilukhetho lokuqala lwabavelisi beemoto.

Ukusebenza kakuhle kokufudumeza

Enye yezona nzuzo ziphambili zeIsifudumezi se-PTC esipholileyos yindlela ezisebenza ngayo kakuhle zokufudumeza. Ezi heater zenzelwe ukufudumeza ngokukhawuleza i-coolant kwiinkqubo zeemoto ezinoxinzelelo oluphezulu, ukuqinisekisa ukuba ingaphakathi lesithuthi kunye nezinto ezibalulekileyo zihlala kumaqondo obushushu afanelekileyo, ingakumbi kwiimeko zemozulu ezibandayo. Itekhnoloji ye-PTC ivumela ukufudumeza okukhawulezayo nokuzinzileyo, inika abantu abakwisithuthi amava okuqhuba akhululekileyo nakhuselekileyo.

Ukuthembeka nokuqina

Izifudumezi zePTC ezipholileyo zaziwa ngokuthembeka kwazo nokuqina kwazo, nto leyo eyenza ukuba zilungele ukusetyenziswa kweemoto ezisebenzisa amandla aphezulu. Ngokungafaniyo neenkqubo zokufudumeza zemveli, izifudumezi zePTC azigugi kakhulu ngenxa yeempawu zazo ezizilawulayo. Oku kuthetha ukuba zinokusebenza ngokufanelekileyo ixesha elide ngaphandle kwesidingo sokugcinwa rhoqo okanye ukutshintshwa, ekugqibeleni kunciphisa iindleko zizonke zobunini bezithuthi.

iingenelo zokhuseleko kunye nokusingqongileyo

Ukongeza kumsebenzi wazo wokufudumeza, ii-PTC coolant heaters zikwabonelela ngezibonelelo zokhuseleko kunye nokusingqongileyo. Ezi heaters zenzelwe ukusebenza kwi-voltage ephezulu ngaphandle komngcipheko wokutshisa kakhulu, nto leyo ezenza zibe lukhetho olukhuselekileyo noluthembekileyo kwiinkqubo zeemoto ezine-voltage ephezulu. Ukongeza, ii-PTC heaters zinobuhlobo nokusingqongileyo njengoko zingaxhomekeki kumafutha efosili ukuze zifudumeze, nto leyo enciphisa umngcipheko wekhabhoni yesithuthi kwaye inceda ekudaleni imeko-bume ecocekileyo neluhlaza.

Ukuguquguquka kunye nokudibanisa

Izifudumezi ze-PTC ezipholileyo zinokusetyenziswa ngeendlela ezahlukeneyo kwaye zinokudityaniswa ngokungenamthungo kwiinkqubo ezahlukeneyo zeemoto ezine-voltage ephezulu. Nokuba sisithuthi esixutyiweyo, sombane okanye se-fuel cell, izifudumezi ze-PTC zinokwenziwa ngokwezifiso ukuze zihlangabezane neemfuno ezithile zokufudumeza zamaqonga ezithuthi ahlukeneyo. Ubungakanani bayo obuncinci kunye neendlela zokufakelwa eziguquguqukayo zenza ukuba ilungele uyilo lweemoto zanamhlanje, ivumela ukuhlanganiswa okungenamthungo ngaphandle kokuphazamisa ukusebenza.

ukusebenza kakuhle kwamandla

Ukusebenza kakuhle kwamandla yinto ephambili kwiinkqubo zeemoto ezine-voltage ephezulu, kwaye ii-heaters ze-PTC coolant ziyabalasela kule nkalo. Ezi heaters zenzelwe ukuguqula umlinganiselo omkhulu wamandla ombane abe bubushushu, ukunciphisa inkunkuma yamandla kunye nokwandisa ukusebenza kakuhle kokufudumeza. Oku akuncedi nje kuphela ekunciphiseni ukusetyenziswa kwamandla ngokubanzi kwesithuthi, kodwa kunceda nokwandisa uluhlu lokuqhuba lwezithuthi zombane, okwenza zifaneleke ngakumbi ukusetyenziswa kwemihla ngemihla.

ukuququmbela

Isishwankathelo,Isifudumezi se-EV esipholileyoIi-s ziye zaba lutshintsho olukhulu kwiinkqubo zeemoto ezine-voltage ephezulu, zibonelela ngeenzuzo ezininzi ezifana nokusebenza kakuhle kokufudumeza, ukuthembeka, ukhuseleko, iingenelo zokusingqongileyo, ukuguquguquka, ukuhlanganiswa kunye nokusebenza kakuhle kwamandla. Njengoko ishishini leemoto liqhubeka nokusebenzisa ubuchwepheshe bokufakelwa kombane kunye ne-voltage ephezulu, ii-PTC coolant heaters ziya kudlala indima ebalulekileyo ekubumbeni ikamva leenkqubo zokufudumeza iimoto. Ngerekhodi yazo eqinisekisiweyo kunye neenzuzo ezininzi, akumangalisi ukuba ii-PTC coolant heaters zilukhetho lokuqala lwabenzi beemoto abafuna ukuphucula ukusebenza kunye nokuzinza kwezithuthi zabo ezine-voltage ephezulu.
