Ukubaluleka kwezimoto zamandla amasha uma kuqhathaniswa nezimoto zendabuko kubonakala kakhulu kulezi zici ezilandelayo: Okokuqala, vimbela ukugijima okushisayo kwezimoto ezintsha ezinamandla.Izimbangela zokushisa okushisayo zihlanganisa izimbangela zemishini nezikagesi (ibhethri ukushayisana, i-acupuncture, njll.) kanye nezimbangela ze-electrochemical (ukushajwa kwebhethri ngokweqile nokuphuma ngokweqile, ukushaja okusheshayo, ukushaja okunokushisa okuphansi, ukujikeleza okufushane kwangaphakathi okuzisungulele ngokwakho, njll.).Ukushisa okushisayo kuzobangela ibhethri lamandla ukuthi libambe umlilo noma liqhume, kubeke engcupheni ukuphepha kwabagibeli.Okwesibili ukuthi izinga lokushisa elilungile lokusebenza lebhethri lamandla ngu-10-30 ° C.Ukuphatha okushisayo kwebhethri okunembile kungaqinisekisa impilo yesevisi yebhethri futhi kunwebe impilo yebhethri yezimoto zamandla amasha.Okwesithathu, uma kuqhathaniswa nezimoto zikaphethiloli, izimoto zamandla amasha azinawo umthombo wamandla we-compressor air-conditioning, futhi azikwazi ukuthembela ekushiseni okulahlwayo okuvela enjinini ukuze zinikeze ukushisa endlini, kodwa zingakwazi ukushayela amandla kagesi kuphela ukuze zilawule ukushisa, okuzonciphisa kakhulu. uhla lokuhamba lwemoto yamandla entsha uqobo.Ngakho-ke, ukuphathwa okushisayo kwezimoto zamandla amasha sekuyisihluthulelo sokuxazulula izingqinamba zezimoto ezintsha zamandla.
Isidingo sokuphathwa okushisayo kwezimoto ezisebenza ngamandla amasha siphezulu kakhulu kunezimoto ezijwayelekile zikaphethiloli.Ukuphathwa kwezimoto ezishisayo ukulawula ukushisa kwemoto yonke kanye nokushisa kwemvelo iyonke, ukugcina ingxenye ngayinye isebenza ebangeni lokushisa elilungile, futhi ngesikhathi esifanayo uqinisekise ukuphepha nokushayela ukunethezeka kwemoto.Uhlelo olusha lokulawula ukushisa kwemoto yamandla ikakhulukazi luhlanganisa uhlelo lwe-air conditioning, uhlelo lokulawula ukushisa kwebhethri(HVCH), uhlelo lokuhlanganisa i-motor electronic control.Uma kuqhathaniswa nezimoto zendabuko, ukuphathwa okushisayo kwezimoto zamandla amasha kungeze amamojula okulawula okushisayo kwebhethri kanye nemoto kagesi.I-traditional automotive thermal management ikakhulukazi ihlanganisa ukupholisa injini no-gearbox kanye nokuphathwa kokushisa kwe-air conditioning system.Izimoto zikaphethiloli zisebenzisa isiqandisi se-air-conditioning ukunikeza ukupholisa kwekhabhini, ukushisisa ikhabethe ngokushisa okulahlwayo okuvela enjinini, futhi zipholise injini no-gearbox ngokupholisa uketshezi noma ukupholisa umoya.Uma kuqhathaniswa nezimoto zendabuko, ushintsho olukhulu ezimotweni zamandla amasha umthombo wamandla.Izimoto zamandla amasha azinazo izinjini zokuhlinzeka ngokushisa, futhi ukushisisa kwesimo somoya kwenziwa nge-PTC noma nge-heat pump air conditioning.Izimoto zamandla amasha zengeze izidingo zokupholisa zamabhethri nezinhlelo zokulawula i-electronic motor, ngakho-ke ukuphatha okushisayo kwezimoto zamandla amasha kuyinkimbinkimbi kunezimoto ezijwayelekile zikaphethiloli.
Inkimbinkimbi yokuphathwa kwe-thermal yezimoto zamandla amasha yenze ukwanda kwenani lemoto eyodwa ekuphathweni kwe-thermal.Inani lemoto eyodwa ohlelweni lokuphatha okushisayo liphindwe izikhathi ezingu-2-3 kunemoto yendabuko.Uma kuqhathaniswa nezimoto zendabuko, ukukhuphuka kwenani lezimoto ezintsha zamandla ikakhulukazi kuvela ekupholiseni uketshezi lwebhethri, ama-air conditioner wepompo lokushisa,I-PTC Coolant heater, njll.
Ukupholisa uketshezi kuthathe indawo yokupholisa komoya njengobuchwepheshe bokulawula izinga lokushisa elivamile, futhi ukupholisa okuqondile kulindeleke ukuthi kuzuze impumelelo yezobuchwepheshe.
Izindlela ezine ezijwayelekile zokulawula ukushisa kwebhethri ukupholisa komoya, ukupholisa uketshezi, ukupholisa impahla yokushintsha isigaba, nokupholisa ngokuqondile.Ubuchwepheshe bokupholisa umoya babusetshenziswa kakhulu kumamodeli okuqala, futhi ubuchwepheshe bokupholisa uketshezi kancane kancane sebuyinto evamile ngenxa yokupholisa okufanayo kokupholisa uketshezi.Ngenxa yezindleko eziphakeme, ubuchwepheshe bokupholisa uketshezi ngokuvamile bufakwe amamodeli asezingeni eliphezulu, futhi kulindeleke ukuthi bucwiliswe kumamodeli asezingeni eliphansi ngokuzayo.
Ukupholisa umoya (I-PTC Air heater) kuyindlela yokupholisa lapho kusetshenziswa khona umoya njengendawo yokudlulisa ukushisa, futhi umoya ukususe ngokuqondile ukushisa kwebhethri ngokusebenzisa ifeni yokukhipha umoya.Ukupholisa umoya, kuyadingeka ukwandisa ibanga phakathi kwamasinki okushisa namasinki okushisa phakathi kwamabhethri ngangokunokwenzeka, futhi iziteshi ze-serial noma ezihambisanayo zingasetshenziswa.Njengoba uxhumano oluhambisanayo lungafinyelela ukuchithwa kokushisa okufanayo, iningi lezinhlelo zamanje zokupholisa umoya zisebenzisa uxhumano oluhambisanayo.
Ubuchwepheshe bokupholisa uketshezi busebenzisa i-liquid convection heat exchange ukususa ukushisa okukhiqizwa ibhethri futhi kwehlise izinga lokushisa lebhethri.I-liquid medium ine-coefficient yokudlulisa ukushisa okuphezulu, umthamo omkhulu wokushisa, nesivinini sokupholisa ngokushesha, esinomthelela obalulekile ekwehliseni izinga lokushisa eliphezulu kanye nokuthuthukisa ukuhambisana kwenkambu yezinga lokushisa yephakethe lebhethri.Ngesikhathi esifanayo, ivolumu yesistimu yokuphatha ukushisa incane kakhulu.Endabeni yezandulela ezishisayo, isixazululo sokupholisa uketshezi singancika ekugelezeni okukhulu kwendawo yokupholisa ukuze kuphoqe iphakethe lebhethri ukuthi likhiphe ukushisa futhi libone ukusabalalisa kabusha ukushisa phakathi kwamamojula webhethri, okungacindezela ngokushesha ukuwohloka okuqhubekayo kokugijima kwe-thermal futhi kunciphise ukushisa. ingozi yokubaleka.Ifomu lesistimu yokupholisa uketshezi ivumelana nezimo: amaseli ebhethri noma amamojula angacwiliswa oketshezini, iziteshi zokupholisa nazo zingasethwa phakathi kwamamojula ebhethri, noma ipuleti lokupholisa lingasetshenziswa ngaphansi kwebhethri.Indlela yokupholisa uketshezi inezidingo eziphezulu ekungangeni komoya kwesistimu.Ukupholisa okubalulekile koshintsho lwesigaba kubhekisela kunqubo yokuguqula isimo sendaba nokuhlinzeka ngokushisa okucashile ngaphandle kokushintsha izinga lokushisa, nokushintsha izici ezibonakalayo.Le nqubo izomunca noma ikhulule inani elikhulu lokushisa okucashile ukupholisa ibhethri.Nokho, ngemva koshintsho oluphelele lwesigaba sezinto ezishintshayo zesigaba, ukushisa kwebhethri akukwazi ukususwa ngokuphumelelayo.
Indlela yokupholisa ngokuqondile (i-refrigerant direct cooling) isebenzisa umgomo wokushisa okucashile kokuhwamuka kweziqandisi (R134a, njll.) ukuze kusungulwe isistimu ye-air conditioning emotweni noma kusistimu yebhethri, futhi ifake isihwamuko sesistimu ye-air conditioning ebhethrini. isistimu, nesiqandisi ku-evaporator Iyahwamuka futhi isuse ukushisa kwesistimu yebhethri ngokushesha nangempumelelo, ukuze kuqedelwe ukupholisa kwesistimu yebhethri.
