Inkqubo yokufudumeza izithuthi zepetroli
Okokuqala, makhe sihlolisise umthombo wobushushu wenkqubo yokufudumeza yesithuthi sepetroli.
Ukusebenza kakuhle kobushushu benjini yemoto kuphantsi kakhulu, malunga ne-30%-40% yamandla aveliswa kukutsha aguqulwa abe ngamandla oomatshini emoto, kwaye okuseleyo kuthathwa yi-coolant kunye negesi yokukhupha umoya. Amandla obushushu athathwa yi-coolant amalunga ne-25-30% yobushushu bokutsha.
Inkqubo yokufudumeza yesithuthi semveli sepetroli kukukhokela i-coolant kwinkqubo yokupholisa injini kwi-air/water heat exchanger ekwi-cab. Xa umoya udlula kwi-radiator, amanzi ashushu aphezulu anokudlulisa ubushushu emoyeni ngokulula, ngaloo ndlela evuthuza. Umoya ongena kwi-cab ngumoya ofudumeleyo.
Inkqubo entsha yokufudumeza amandla
Xa ucinga ngezithuthi zombane, kunokuba lula ukuba wonke umntu acinge ukuba inkqubo yeheater esebenzisa ngokuthe ngqo i-resistance wire ukufudumeza umoya ayanelanga. Ngokwethiyori, kunokwenzeka ngokupheleleyo, kodwa phantse azikho iinkqubo ze-resistance wire heater zezithuthi zombane. Isizathu kukuba i-resistance wire idla umbane omninzi kakhulu.
Okwangoku, iindidi ezintshaiinkqubo zokufudumeza amandlaZimbini iindidi eziphambili, enye kukufudumeza nge-PTC, enye yiteknoloji yepompo yobushushu, kwaye ukufudumeza nge-PTC kwahlulwe ngokwahlukeneyo.i-PTC yomoya kunye ne-PTC epholileyo.
Umgaqo wokufudumeza wenkqubo yokufudumeza yohlobo lwe-PTC thermistor ulula kwaye kulula ukuwuqonda. Ufana nenkqubo yokufudumeza i-resistance wire heating, exhomekeke kumbane ukuze ivelise ubushushu ngokusebenzisa i-resistance. Umahluko kuphela zizinto ezisetyenziswa yi-resistance. I-resistance wire yi-metal wire eqhelekileyo exhathisayo kakhulu, kwaye i-PTC esetyenziswa kwizithuthi zombane ezicocekileyo yi-semiconductor thermistor. I-PTC sisifinyezo se-Positive Temperature Coefficient. Ixabiso le-resistance nalo liya kwanda. Olu phawu lumisela ukuba phantsi kwemeko ye-voltage engaguqukiyo, i-PTC heater ishushu ngokukhawuleza xa ubushushu buphantsi, kwaye xa ubushushu bunyuka, ixabiso le-resistance liba likhulu, umbane uba mncinci, kwaye i-PTC itya amandla amancinci. Ukugcina ubushushu buhlala bunjalo kuya konga umbane xa kuthelekiswa ne-resistance wire heating ecocekileyo.
Zizo ezi nzuzo ze-PTC ezamkelwe kakhulu zizithuthi zombane ezicocekileyo (ingakumbi iimodeli ezikumgangatho ophantsi).
Ukufudumeza kwe-PTC kwahlulwe kabiniIsifudumezi sokupholisa se-PTC kunye nesifudumezi somoya.
Isifudumezi samanzi se-PTCidla ngokudityaniswa namanzi okupholisa enjini. Xa izithuthi zombane zisebenza kunye nenjini isebenza, nayo injini iya kushushu. Ngale ndlela, inkqubo yokufudumeza ingasebenzisa inxalenye yenjini ukufudumeza kwangaphambili ngexesha lokuqhuba, kwaye inokonga umbane. Umfanekiso ongezantsi nguIsifudumezi sokupholisa esine-voltage ephezulu ye-EV.
Emva kweukufudumeza amanzi i-PTCifudumeza i-coolant, i-coolant iya kudlula kwi-heating core ekwi-cab, ize ifane nenkqubo yokufudumeza yesithuthi sepetroli, kwaye umoya osekhabhini uya kujikeleziswa kwaye ufudunyezwe phantsi kwesenzo se-blower.
Iukufudumeza umoya i-PTCkukufaka i-PTC ngqo kwi-heater core yekhabhathi, ukujikeleza umoya emotweni nge-blower kunye nokufudumeza umoya ngqo kwikhabhathi nge-PTC heater. Ulwakhiwo lulula, kodwa lubiza kakhulu kune-PTC yokufudumeza amanzi.
