Iisifudumezi sebhethri semoto entsha yamandlaingagcina ibhethri lisezingeni lokushisa elifanele ukuqinisekisa ukusebenza okuvamile kohlelo lonke lwemoto. Uma izinga lokushisa liphansi kakhulu, lawa ma-ion e-lithium azoqandiswa, avimbele ukunyakaza kwawo, okubangela ukuthi amandla okunikezwa kwamandla ebhethri ehle kakhulu. Ngakho-ke, ebusika noma lapho izinga lokushisa liphansi kakhulu, kuyadingeka ukushisa ibhethri kusengaphambili.
Uhlelo lokushisa ibhethri lwezimoto zikagesi ezintsha ezisebenzisa amandla ahlanzekile lusebenzisa kakhulu lezi zindlela ezimbili ezilandelayo: ukushisa kusengaphambili kanye nokushisa ngamanzi kaphethiloli. Ngokufaka i-heater yokushisa amanzi emotweni entsha kagesi enamandla, ibhethri lifudunyezwa ngokudluliselwa kokushisa ukuze lifinyelele izinga lokushisa elijwayelekile lokusebenza.Izifudumezi zikagesi ezinamandla aphezulu ezintshaingadlulisela ukushisa ebhethrini lemoto kagesi ukuze ifudumale kusengaphambili futhi igcine izinga lokushisa lokusebenza elijwayelekile ngokuyifakaIzifudumezi ze-PTCezimotweni ezintsha zikagesi ezisebenzisa amandla.
Isixazululo sesistimu yokushisa yebhethri yemoto kagesi ehlanzekile Ebusika, impilo yebhethri yezimoto zikagesi ezintsha ezisebenzisa amandla ngokuvamile izoncipha kakhulu, ikakhulukazi ngoba emazingeni okushisa aphansi, i-viscosity ye-electrolyte ephaketheni lebhethri iyanda futhi ukusebenza kokushaja nokukhipha kwephakethe lebhethri kwehla.
Ngokwemfundiso: Akuvunyelwe ukushaja amabhethri e-lithium endaweni engaphansi kwama-degree Celsius angama-20 (kuzolimaza ibhethri). Izimoto zikagesi zingaxazulula inkinga yokuphila kwebhethri okuncishisiwe kwezimoto zikagesi ezintsha ezinamandla ezindaweni eziphansi ebusika ngokufaka i-isifudumezi sokupakaukushisa ibhethri lezimoto ezintsha zamandla kusengaphambili ukuze libe sezingeni lokushisa elijwayelekile lokusebenza futhi ugweme ukulimala kwebhethri okubangelwa ukushaja okuphansi kokushisa.
Isifudumezi se-PTC, esibizwa nangokuthiIsici sokushisa se-PTC, yakhiwe yiIsici sokushisa se-ceramic se-PTCkanye neshubhu le-aluminium. Lolu hlobo lwesifudumezi se-PTC lunezinzuzo zokumelana nokushisa okuncane kanye nokusebenza kahle kokushintshana kokushisa okuphezulu. Luyizinga lokushisa elizenzakalelayo elingaguquki kanye nokonga amandlaisifudumezi sikagesi. Isici esivelele sisekusebenzeni. Okusho ukuthi, lapho ifeni ihluleka futhi ima, amandla e-PTC heater azokwehla ngokuzenzakalelayo ngoba awakwazi ukuqeda ukushisa okwanele. Ngalesi sikhathi, izinga lokushisa lobuso be-heater ligcinwa cishe ezingeni lokushisa le-Curie (ngokuvamile elingu-250°C) phezulu naphansi), ukuze kugwenywe isimo "sokubomvu" ebusweni be-heater kagesi, okungeke kubangele ukusha, imililo nezinye izingozi ezifihliwe.
Iqukethe amashidi e-aluminium aqeda ukushisa, amashubhu e-aluminium, amashidi okuhambisa umoya, amafilimu okufaka ukushisa, amashidi okushisa e-PTC, amatheminali e-electrode yethusi e-nickel kanye nama-sheath e-electrode epulasitiki ashisa kakhulu. Ngenxa yokusebenzisa ama-heat sink afanele ukucindezela, lo mkhiqizo uthuthukisa izinga lawo lokushabalalisa ukushisa futhi ucabangela ngokugcwele izimo ezahlukahlukene zokushisa nezogesi ze-PTC heating element ngesikhathi sokusebenza. Inamandla okubopha aqinile, i-heat conductivity enhle kakhulu kanye nokusebenza kahle kokushabalalisa ukushisa, ukusebenza kahle okuphezulu kanye nokuthembeka. Lolu hlobo lwe-PTC heater lunezinzuzo zokumelana nokushisa okuncane kanye nokusebenza kahle kokushintshana kokushisa okuphezulu. I-heater kagesi ezenzakalelayo engaguquki kanye nokonga amandla.
Umgomo we-PTC heater Ukushisa okushisa njalo I-PTC thermistor inezici zokushisa okushisa njalo. Umgomo uwukuthi ngemva kokuba i-PTC thermistor ivuliwe, iyazifudumeza futhi inani lokumelana lingena endaweni yokuguquka. Izinga lokushisa lobuso be-PTC thermistor yokushisa okushisa njalo lizogcina inani elihlala njalo. Izinga lokushisa lihlobene kuphela nokushisa kwe-Curie kwe-PTC thermistor kanye ne-voltage esetshenzisiwe, futhi empeleni alinalutho oluphathelene nokushisa okuzungezile.
