Ukuphathwa kokushisa okuphelele kwebhasi lamaseli kaphethiloli kuhlanganisa kakhulu: ukuphathwa kokushisa kwamaseli kaphethiloli, ukuphathwa kokushisa kwamaseli kagesi, ukufudumeza kwasebusika kanye nokupholisa kwasehlobo, kanye nomklamo wokuphathwa kokushisa okuphelele kwebhasi ngokusekelwe ekusetshenzisweni kokushisa okulahliwe kwamaseli kaphethiloli.
Izingxenye eziyinhloko zesistimu yokuphathwa kokushisa kwamaseli kaphethiloli zifaka kakhulu: 1) Iphampu yamanzi: iqhuba ukujikeleza kwe-coolant. 2) Isinki yokushisa (i-core + fan): yehlisa izinga lokushisa le-coolant futhi isusa ukushisa okulahliwe kwamaseli kaphethiloli. 3) I-Thermostat: ilawula ukujikeleza kosayizi we-coolant. 4) Ukushisa kukagesi kwe-PTC: kushisa i-coolant ekushiseni okuphansi kuqala ukushisa iseli kaphethiloli. 5) Iyunithi ye-Deionization: imunca ama-ion ku-coolant ukuze inciphise ukuhanjiswa kukagesi. 6) I-Antifreeze yamaseli kaphethiloli: indawo yokupholisa.
Ngokusekelwe ezicini zeseli likaphethiloli, iphampu yamanzi yohlelo lokuphatha ukushisa inezici ezilandelayo: ikhanda eliphezulu (uma amaseli amaningi, isidingo sekhanda siphezulu), ukugeleza okuphezulu kokupholisa (ukushabalalisa ukushisa okungu-30kW ≥ 75L/min) kanye namandla alungisekayo. Ngemuva kwalokho ijubane lephampu namandla kuyalinganiswa ngokuya ngokugeleza kokupholisa.
Umkhuba wesikhathi esizayo wokuthuthukiswa kwephampu yamanzi kagesi: ngaphansi kwesisekelo sokwanelisa izinkomba eziningana, ukusetshenziswa kwamandla kuzoncishiswa njalo futhi ukuthembeka kuzokhushulwa njalo.
Isinki yokushisa yakhiwe yi-heat sink core kanye ne-cooling fan, kanti i-heat sink yindawo yesinki yokushisa yeyunithi.
Umkhuba wokuthuthukiswa kwe-radiator: ukuthuthukiswa kwe-radiator ekhethekile yamaseli kaphethiloli, maqondana nokuthuthukiswa kwezinto, okudingekayo ukuthuthukisa ukuhlanzeka kwangaphakathi nokunciphisa izinga lokuna kwe-ion.
Izinkomba eziyinhloko zefeni yokupholisa amandla efeni kanye nomthamo womoya ophezulu. Ifeni yemodeli engu-504 inomthamo womoya ophezulu ongu-4300m2/h kanye namandla alinganiselwe angu-800W; ifeni yemodeli engu-506 inomthamo womoya ophezulu ongu-3700m3/h kanye namandla alinganiselwe angu-500W. Ifeni ngokuyinhloko injalo.
Umkhuba wokuthuthukiswa kwefeni yokupholisa: ifeni yokupholisa ingashintsha kamuva epulatifomu ye-voltage, izivumelanise ngqo ne-voltage yeseli kaphethiloli noma iseli yamandla, ngaphandle kwesiguquli se-DC/DC, ukuze kuthuthukiswe ukusebenza kahle.
Isifudumezi sokushisa sikagesi se-PTC
Ukushisa ngogesi kwe-PTC kusetshenziswa kakhulu enkambisweni yokuqala izinga lokushisa eliphansi lamaseli kaphethiloli ebusika, ukushisa ngogesi kwe-PTC kunezikhundla ezimbili ohlelweni lokuphathwa kokushisa kwamaseli kaphethiloli, emjikelezweni omncane kanye nasemgqeni wamanzi wokwenza izimonyo, umjikelezo omncane yiwona ovame kakhulu.
Ebusika, lapho izinga lokushisa eliphansi liphansi, amandla athathwa kuseli lamandla ukuze kufudunyezwe i-coolant emjikelezweni omncane kanye nombhobho wamanzi wokwenza izimonyo, bese i-coolant eshisayo ifudumeza i-reactor kuze kube yilapho izinga lokushisa le-reactor lifinyelela inani eliqondiwe, futhi iseli likaphethiloli lingaqaliswa futhi ukushisa kukagesi kumiswe.
Ukushisa kukagesi kwe-PTC kuhlukaniswe ngama-voltage aphansi kanye nama-voltage aphezulu ngokweplatifomu yamandla kagesi, ama-voltage aphansi ikakhulukazi angama-24V, okudingeka aguqulwe abe yi-24V yi-converter ye-DC/DC. Amandla okushisa kukagesi ama-voltage aphansi kakhulu anqunyelwe yi-converter ye-24V DC/DC, okwamanje, i-converter ephezulu ye-DC/DC yama-voltage aphezulu kuya ku-24V ama-voltage aphansi angama-6kW kuphela. Ama-voltage aphezulu kakhulu angama-450-700V, afana ne-voltage yeseli yamandla, futhi amandla okushisa angaba makhulu kakhulu, ikakhulukazi kuye ngomthamo we-heater.
Njengamanje, uhlelo lwe-fuel cell lwasekhaya luqalwa kakhulu ngokushisa kwangaphandle, okungukuthi, ukufudumala ngokushisa kwe-PTC; izinkampani zaphesheya kwezilwandle ezifana neToyota zingaqala ngqo ngaphandle kokushisa kwangaphandle.
Isiqondiso sokuthuthukiswa kokushisa ngogesi kwe-PTC kohlelo lokuphathwa kokushisa kwamaseli kaphethiloli yi-miniaturization, ukuthembeka okuphezulu kanye nokushisa ngogesi kwe-PTC okuphephile okunamandla aphezulu.
