Njengoko ihlabathi lisiya kwikamva elizinzileyo, ishishini leemoto litshintsha kakhulu liye kwizithuthi zombane (ii-EV). Ngolu tshintsho, imfuneko yetekhnoloji yokuphola nokufudumeza esebenzayo iye yaba yinto ebalulekileyo ekusebenzeni kakuhle kwezithuthi zombane. Kweli nqaku, sihlola ukubalulekaIsipholisi se-EV, inkqubela phambili kubuchwepheshe be-EV coolant, kunye nendima ebalulekileyo ye-positive temperature coefficient (PTC) heaters ekuqinisekiseni intuthuzelo kunye nokusebenza kwe-EV.
Izipholisi zezithuthi zombane: Isitshixo solawulo lobushushu
Ulawulo lobushushu lubalulekile ekusebenzeni, ekuthembekeni nasekuhlaleni ixesha elide kwezithuthi zombane. Izinto zokupholisa izithuthi zombane zidlala indima ebalulekileyo ekugcineni ubushushu obufanelekileyo kwiindawo ezahlukeneyo ezifana neebhetri, iimoto zombane, izixhobo zombane kunye neenkqubo zokutshaja. Ezi zinto zokupholisa azithinteli nje kuphela ubushushu obugqithisileyo kodwa zikwanceda ukugcina ubushushu obufunekayo ngexesha lemozulu embi.
Inkqubela phambili yakutshanje kubuchwepheshe be-coolant yezithuthi zombane ikhuthaze uphuhliso lwezisombululo zokupholisa eziphambili, ezifana ne-coolant ezihlala ixesha elide ezinozinzo oluphuculweyo lobushushu kunye neempawu eziphuculweyo zokudlulisa ubushushu. Ezi coolant zenzelwe ukumelana nobushushu obuphezulu bokusebenza kwe-powertrains zombane, ukuqinisekisa ukuchithwa kobushushu ngokufanelekileyo kunye negalelo ekuthembekeni ngokubanzi kwezithuthi zombane.
Izinto zokupholisa izithuthi zombane: iiparameter ezibalulekileyo kunye neemfuno
Xa ukhetha i-coolant yesithuthi sombane, kukho izinto ezininzi ekufuneka ziqwalaselwe. Okokuqala, i-coolant kufuneka ibe ne-thermal conductivity egqwesileyo ukuze isuse ubushushu kwiindawo ezibalulekileyo. Okwesibini, kufuneka ibe nendawo yokubila ephezulu ukuze ithintele ukufuma phantsi kweemeko ezinzima. Ukongeza, i-coolant kufuneka ibe nokumelana okuhle nokugqwala ukuqinisekisa ukuba inkqubo yokupholisa ihlala ixesha elide.
Ukongeza, uzinzo lokusingqongileyo luyinto exhalabisayo. Ii-coolers zezithuthi zombane ezibolayo nezinobuhlobo nokusingqongileyo ziya zithandwa kakhulu ngabenzi beemoto, ngokuhambelana nokuzibophelela kweshishini ekunciphiseni umngcipheko wekhabhoni kulo lonke ixesha lomjikelo wobomi bezithuthi.
Isifudumezi se-PTC: ukuqinisekisa intuthuzelo kunye nokusebenza kakuhle kwamandla
Ukongeza ekupholiseni, ukufudumeza kudlala indima ebalulekileyo kwintuthuzelo nokusebenza kakuhle kwesithuthi sombane. Ii-PTC heaters ziitekhnoloji zokufudumeza ezikhethwayo kwishishini leemoto ngenxa yokusebenza kakuhle kwamandla kunye nokusebenza okuthembekileyo. Ezi heaters zisebenzisa i-coefficient yobushushu efanelekileyo yezixhobo ezithile ukuze zizilawulele ngokwazo ukuveliswa kobushushu, ukuqinisekisa ukufudumeza okuhlala kuhleli nokulawulwayo.
Isifudumezi se-PTC sibonelela ngokufudumeza ngokukhawuleza, sivumela abakhweli ukuba bonwabele ubushushu obukhululekileyo bekhabhini kwiimeko zemozulu ebandayo ngelixa sinciphisa ukusetyenziswa kwamandla. Ukongeza, ezi zifudumezi ziyakwazi ukuzilawula ngokwazo ubushushu, zibonelela ngolawulo oluchanekileyo lobushushu, zisusa imfuneko yeendlela ezongezelelweyo zolawulo.
Ukudibanisa ii-PTC heaters kwizithuthi zombane kunciphisa kakhulu ukuxhomekeka kwiindlela zokufudumeza zemveli ezifana nee-resistive heaters, ezingasebenzi kakuhle kumbane kwaye zihlala zifuna amandla ebhetri amaninzi, nto leyo echaphazela kakubi umgama wokuqhuba kwesithuthi.
Uphuhliso kunye nefuthe lexesha elizayo
Njengoko imfuno yezithuthi zombane iqhubeka ikhula, kulindeleke ukuba iteknoloji ye-coolant kunye ne-PTC heater ihambe phambili. Abaphandi kunye nabavelisi basebenza ukuphuhlisa ii-coolant eziphambili ezisebenza kakuhle kakhulu kubushushu kunye nolwakhiwo oluphuculweyo ukuhlangabezana neemfuno ezitshintshayo zezixhobo zombane zesizukulwana esilandelayo.
Ukongeza, ukuqhubela phambili kuyilo lwe-PTC heater kunye nokuhlanganiswa neenkqubo zolawulo lwe-thermal ezikrelekrele kunokuphucula ukusebenza kwazo ngakumbi. Olu phuhliso aluyi kuqinisekisa kuphela intuthuzelo yabakhweli kwaye lunciphise ukusetyenziswa kwamandla, kodwa luya kuphucula uluhlu olubanzi lwezithuthi zombane.
ukuququmbela
Ukuthandwa okukhulayo kwezithuthi zombane kufuna izisombululo eziqinileyo zolawulo lobushushu ukuze zisebenze kakuhle kwaye zihlale ixesha elide. Ngokuphuculwa kokuqhuba kobushushu kunye nokumelana nokugqwala, ii-EV coolants zidlala indima ebalulekileyo ekugcineni ubushushu obufunekayo kunye nokuthintela ubushushu obugqithisileyo. Kwangaxeshanye, ubuchwepheshe bokufudumeza obuphambili obufana nezifudumezi ze-PTC buqinisekisa intuthuzelo yabakhweli ngelixa bunciphisa ukusetyenziswa kwamandla. Njengoko imakethi yezithuthi zombane ikhula ngokukhawuleza, uphuhliso oluqhubekayo lwetekhnoloji entsha yokupholisa kunye nobushushu luhlala lubalulekile kwikamva lothutho oluzinzileyo.
