Ukuphathwa okushisayo kwesistimu yamandla ezimoto kuhlukaniswe phakathi kokuphathwa okushisayo kwesistimu yamandla kaphethiloli evamile kanye nokuphathwa kokushisa kwesistimu entsha yamandla emoto yamandla.Manje ukuphathwa okushisayo kwesistimu yamandla kaphethiloli yendabuko sekuvuthwe kakhulu.Imoto kaphethiloli yendabuko inikwa amandla injini, ngakho-ke ukulawulwa kwe-Thermal kwenjini kugxile ekulawuleni okujwayelekile kwezimoto ezishisayo.Ukuphathwa okushisayo kwenjini ikakhulukazi kuhlanganisa uhlelo lokupholisa lwenjini.Ukushisa okungaphezu kuka-30% ohlelweni lwemoto kudinga ukukhishwa yisekethe yokupholisa injini ukuze kuvinjwe injini ekushiseni ngokweqile ngaphansi kokusebenza komthwalo omkhulu.Isipholile senjini sisetshenziselwa ukushisa ikhabethe.
Isizinda samandla sezimoto zikaphethiloli esivamile sakhiwe izinjini kanye nokudluliswa kwezimoto zikaphethiloli ezivamile, kuyilapho izimoto zamandla amasha zakhiwe amabhethri, izinjini, nezilawuli zikagesi.Izindlela zokuphatha ezishisayo zalezi ezimbili zenze izinguquko ezinkulu.Ibhethri lamandla ezimoto zamandla amasha Ibanga lokushisa elivamile lokusebenza ngu-25℃ 40℃.Ngakho-ke, ukuphathwa okushisayo kwebhethri kudinga kokubili ukuyigcina ifudumele nokuyichitha.Ngesikhathi esifanayo, izinga lokushisa le-motor akufanele libe phezulu kakhulu.Uma izinga lokushisa lemoto liphezulu kakhulu, lizothinta impilo yesevisi yemoto.Ngakho-ke, injini nayo idinga ukuthatha izinyathelo ezidingekayo zokukhipha ukushisa ngesikhathi sokusetshenziswa.Okulandelayo isingeniso sohlelo lokulawula ukushisa kwebhethri kanye nesistimu yokulawula ukushisa kwemoto yokulawula i-electronic kanye nezinye izingxenye.
Isistimu yokulawula ukushisa kwebhethri yamandla
Isistimu yokuphatha okushisayo yebhethri yamandla ihlukaniswe ngokuyinhloko ekupholiseni komoya, ukupholisa uketshezi, ukupholisa izinto ezishintshayo kwesigaba kanye nokupholisa amapayipi okushisa okusekelwe emithonjeni ehlukene yokupholisa.Izimiso nezakhiwo zesistimu zezindlela zokupholisa ezihlukene zihluke kakhulu.
1) Ukupholisa komoya kwebhethri lamandla: iphakethe lebhethri nomoya wangaphandle uhambisa ukushintshana kokushisa okuguquguqukayo ngokugeleza komoya.Ukupholisa komoya ngokuvamile kuhlukaniswa ngokupholisa kwemvelo nokupholisa ngempoqo.Ukupholisa ngokwemvelo yilapho umoya wangaphandle upholisa iphakethe lebhethri lapho imoto isebenza.Ukupholisa komoya okuphoqelelwe ukufaka ifeni yokupholisa ngempoqo ngokumelene nephakethe lebhethri.Izinzuzo zokupholisa umoya yizindleko eziphansi kanye nokusetshenziswa okulula kwezohwebo.Okubi ukusebenza kahle kokukhipha ukushisa okuphansi, isilinganiso esikhulu sokuhlala endaweni, kanye nezinkinga ezinkulu zomsindo.(I-PTC Air heater)
2) Ukupholisa uketshezi lwebhethri lamandla: ukushisa kwephakethe lebhethri kususwa ukugeleza koketshezi.Njengoba umthamo wokushisa othize woketshezi umkhulu kunomoya, umphumela wokupholisa wokupholisa uketshezi ungcono kunalowo wokupholisa umoya, futhi isivinini sokupholisa sishesha kakhulu kunesokupholisa komoya, kanye nokusatshalaliswa kwezinga lokushisa ngemva kokushiswa kokushisa Ibhethri iphakethe iyafana.Ngakho-ke, ukupholisa uketshezi nakho kusetshenziswa kabanzi kwezohwebo.(I-PTC Coolant heater)
3) Ukupholisa izinto zokushintsha isigaba: Izinto zokushintsha isigaba (PhaseChangeMaterial, PCM) zihlanganisa upharafini, usawoti onama-hydrated, ama-fatty acids, njll., angamunca noma akhiphe inani elikhulu lokushisa okucashile lapho kwenzeka ushintsho, kuyilapho izinga lokushisa lawo lihlala. engaguquki.Ngakho-ke, i-PCM inomthamo omkhulu wokugcina amandla ashisayo ngaphandle kokusetshenziswa kwamandla okwengeziwe, futhi isetshenziswa kakhulu ekupholiseni kwebhethri kwemikhiqizo kagesi efana nomakhalekhukhwini.Kodwa-ke, ukusetshenziswa kwamabhethri kagesi wezimoto kusesesimeni socwaningo.Izinto zokushintshwa kwesigaba zinenkinga ye-conductivity ephansi yokushisa, okubangela ukuthi ubuso be-PCM obuthinta ibhethri buncibilike, kuyilapho ezinye izingxenye zingancibiliki, okunciphisa ukusebenza kokudlulisa ukushisa kwesistimu futhi akufanelekile amandla amakhulu. amabhethri.Uma lezi zinkinga zingaxazululwa, ukupholisa kwe-PCM kuzoba yisixazululo esikhulu kunazo zonke sokuthuthukiswa kokuphathwa okushisayo kwezimoto zamandla amasha.
I-4) Ukupholisa amapayipi okushisa: Ipayipi lokushisa liyidivayisi esekelwe ekudlulisweni kokushisa kwesigaba.Ipayipi lokushisa liyisitsha esivaliwe noma ipayipi elivaliwe eligcwele indawo yokusebenza/uketshezi olugcwele (amanzi, i-ethylene glycol, noma i-acetone, njll.).Ingxenye eyodwa yepayipi yokushisa iwukuphela kokuhwamuka, kanti enye isiphetho se-condensation.Ayikwazi nje ukumunca ukushisa kwephakethe lebhethri kodwa futhi ukushisa iphakethe lebhethri.Njengamanje iwuhlelo olufanele kakhulu lokulawula ukushisa kwebhethri lamandla.Nokho, isacutshungulwa.
5) Ukupholisa okuqondile kwesiqandisi: ukupholisa okuqondile kuyindlela yokusebenzisa umgomo we-refrigerant ye-R134a nezinye iziqandisi ukuze zihwamuke futhi zimunce ukushisa, futhi ufake i-evaporator yesistimu ye-air conditioning ebhokisini lebhethri ukuze upholise ngokushesha ibhokisi lebhethri.Isistimu yokupholisa eqondile inezinga eliphezulu lokupholisa kanye namandla amakhulu okupholisa.
