Inkcazo

Njengoko izithuthi zombane (EVs) ziqhubeka nokufumana i-traction kwi-automotive industry, ubuchwepheshe obutsha buphuhliswa ukuze busebenze ngakumbi kwaye buthembeke.Obunye ubuchwephesha obunjalo yi-high-voltage ye-PTC (i-coefficient yobushushu obufanelekileyo) heater, esetyenziswa njengesifudumezi sombane sokupholisa kwizithuthi zombane.Kule bhlog, siza kuxoxa ngeenzuzo zokusebenzisa ii-heaters ze-PTC eziphezulu zombane kwizithuthi zombane.

Okokuqala, i-high-voltage PTC heater iyona nxalenye ephambili kwinkqubo yokulawula i-thermal yezithuthi zombane.Inceda ukugcina amaqondo obushushu afanelekileyo kwibhetri yesithuthi sakho kunye ne-drivetrain, ukuqinisekisa ukusebenza ngokufanelekileyo kunye nokwandisa ubomi bala macandelo abalulekileyo.Ngokungafaniyo neenqwelo zenjini zokutsha zangaphakathi, izithuthi zombane azivelisi ubushushu benkunkuma, ngoko ke enye indlela iyafuneka ukufudumeza ingaphakathi lesithuthi kunye nokugcina ubushushu bebhetri kwiindawo ezibandayo.Izifudumezi zePTC ezinoxinzelelo oluphezulu zisisisombululo esisebenzayo kulo mngeni kuba zinokuvelisa ubushushu ngokukhawuleza ngaphandle kwesidingo seenkqubo zokupholisa ezintsonkothileyo nezininzi.

Ukongeza, izifudumezi zePTC ezinevoltage ephezulu zaziwa ngamandla azo okufudumeza okukhawulezayo, okuzenza zilungele izithuthi zombane.Ezi zifudumezi zisebenzisa izinto ze-ceramic eziqhubayo ezilungelelanisa ngokuzenzekelayo amandla ezidlayo, ezivumela ukukhawuleza kunye nokufudumeza.Oku kubaluleke kakhulu kwizithuthi zombane, apho ukusetyenziswa kwamandla kubaluleke kakhulu.Ngokusebenzisa izifudumezi ze-PTC eziphezulu, abavelisi bezithuthi zombane banokuqinisekisa ukuba ingaphakathi lesithuthi lifudumala ngokukhawuleza nangokufanelekileyo ngaphandle kokukhupha ibhetri ngokungafanelekanga.

Ukongeza kwizakhono zabo zokufudumeza ngokukhawuleza, izifudumezi eziphezulu ze-PTC ziyaziwa ngokuthembeka kunye nokhuseleko lwazo.Ngokungafaniyo nezinto zokufudumeza zemveli, izifudumezi ze-PTC azithembeli kwinzwa yobushushu eyahlukileyo ukulawula ukuphuma kwazo.Endaweni yoko, zilawula ukusetyenziswa kwamandla ngokusekwe kubushushu bendawo ezingqongileyo.Olu phawu oluzilawulayo lubenza bangabikho lula ekushiseni, into ebalulekileyo yokuqwalaselwa kokhuseleko kwizithuthi zombane.Ukongeza, izifudumezi ze-PTC ziyilelwe ukumelana nokothuka kwe-thermal kunye noxinzelelo lomatshini, ngakumbi ukonyusa ukuthembeka kwazo ekufuneni izicelo zemoto.

Olunye uncedo olubalulekileyo lokusebenzisa izifudumezi ze-PTC eziphezulu ze-voltage kwizithuthi zombane bubunzima bazo kunye noyilo oluhlangeneyo.Abavelisi bezithuthi zombane bahlala besebenza ukunciphisa ubunzima kunye nobukhulu bezithuthi zabo ukunyusa uluhlu kunye nokusebenza.Ngokusebenzisaheater PTC high-voltages, abavelisi banokuphelisa imfuno yeenkqubo zokupholisa ezininzi, ukukhulula indawo exabisekileyo kwizithuthi kunye nokunciphisa ubunzima obupheleleyo.Oku akugcini nje ukwandisa ukusebenza kakuhle kwesithuthi, kodwa kwakhona kuvumela ukhetho olungakumbi lokuyila kunye nokuguquguquka koyilo.

Ekugqibeleni, izifudumezi ze-PTC eziphezulu ze-voltage zibonelela ngesisombululo sokufudumeza esizinzileyo kunye nokusingqongileyo kwizithuthi zombane.Ngokungafaniyo nezifudumezi zemveli ezixhomekeke kumafutha efosili okanye kwiinkqubo zokupholisa ezintsonkothileyo, izifudumezi ze-PTC zisebenzisa umbane ukwenza ubushushu, zizenze zibe lukhetho olucocekileyo nolusebenzayo lokufudumeza.Oku kuhambelana nenjongo iyonke yezithuthi zombane zokunciphisa ukukhutshwa kwekhabhoni kunye nokuxhomekeka kwimithombo yamandla engahlaziyekiyo.Ukongeza, indalo yokuzilawula ye-PTC heater iqinisekisa ukuba zisebenzisa kuphela isixa esiyimfuneko sombane, ngaloo ndlela kuncitshiswe inkcitho yamandla.

Isishwankathelo, ukusebenzisa i-high-voltage PTC heaters kwizithuthi zombane kunika iingenelo ezininzi, kubandakanywa amandla okufudumala ngokukhawuleza, ukuthembeka, ukhuseleko, ukuyila okulula, kunye nokuzinza kwendalo.Njengoko imfuno yezithuthi zombane iqhubeka nokukhula, abavelisi kufuneka baphumeze izisombululo zolawulo oluphezulu lwe-thermal, ezifana ne-high-voltage PTC heaters, ukwandisa ukusebenza kakuhle kwesithuthi kunye nokusebenza.Ngokusebenzisa obu buchwephesha obutsha, izithuthi zombane zinokubonelela ngamava okuqhuba akhululekileyo nathembekileyo ngelixa zinciphisa impembelelo yokusingqongileyo.
