Iiheater entsha yebhetri yemotoinokugcina ibhetri kwiqondo lokushisa elifanelekileyo ukuqinisekisa ukusebenza okuqhelekileyo kwayo yonke inkqubo yesithuthi.Xa ubushushu buphantsi kakhulu, ezi ion ze-lithium ziya kuba ngumkhenkce, zithintele intshukumo yazo, nto leyo ebangela ukuba amandla ebhetri ehle kakhulu.Ngoko ke, ebusika okanye xa iqondo lobushushu liphantsi kakhulu, kuyimfuneko ukutshisa ibhetri kwangaphambili.
Inkqubo yokufudumeza ibhetri yamandla amatsha ezithuthi zombane ezicocekileyo zisebenzisa ezi ndlela zimbini zilandelayo: ukufudumala kunye nokufudumala kwamanzi.Ngokufakela i-heater yamanzi kwisithuthi sombane samandla amatsha, ipakethi yebhetri ifudunyezwa ngokugqithiswa kobushushu ukufikelela kubushushu obuqhelekileyo bokusebenza.Izifudumezi zombane ezinombane onamandla amatshainokudlulisa ubushushu kwipakethi yebhetri yemoto yombane ukuyitshisa kwangaphambili kwaye uyigcine kubushushu obuqhelekileyo bokusebenza ngokufakaIiheater zePTCkwiimoto zombane zamandla amatsha.
Amandla amatsha ebhetri yemoto yombane esulungekileyo isisombululo senkqubo yokufudumeza ebusika, ubomi bebhetri yezithuthi zombane zamandla amatsha buya kuncitshiswa kakhulu, ikakhulu ngenxa yokuba kumaqondo obushushu aphantsi, i-viscosity ye-electrolyte kwipakethi yebhetri iyanda kunye nentlawulo kunye nokusebenza kokukhupha. ipakethi yebhetri iyancipha.
Ngokwethiyori: Akuvumelekanga ukubiza iibhetri ze-lithium kwindawo engaphantsi kwe-20 degrees Celsius (iya kubangela umonakalo kwibhetri).Izithuthi zombane zinokusombulula ingxaki yokunciphisa ubomi bebhetri yezithuthi zombane zamandla amatsha kwiindawo ezinobushushu obuphantsi ebusika ngokufakaiheater yokupakaukutshisa kwangaphambili ipakethi yebhetri yezithuthi zamandla amatsha ukuze ibekwiqondo lobushushu eliqhelekileyo lokusebenza kwaye uthintele umonakalo kwipakethi yebhetri obangelwa kukutshaja okuphantsi kobushushu.
PTC heater, ikwabizwa ngokubaInto yokufudumeza i-PTC, yenziweI-PTC ye-ceramic yokufudumeza intokunye ne-aluminium tube.Olu hlobo lwe-heater ye-PTC luneenzuzo zokuchasana kwe-thermal encinci kunye nokusebenza kakuhle kokutshintsha kobushushu.Bubushushu obuzenzekelayo obuzenzekelayo kunye nokugcina amandlaisifudumezi sombane.Isici esibalaseleyo silele ekusebenzeni.Oko kukuthi, xa i-fan ihluleka kwaye iyeka, amandla e-heater ye-PTC aya kuhla ngokukhawuleza ngenxa yokuba ayikwazi ukukhupha ukushisa okwaneleyo.Ngeli xesha, ubushushu bomphezulu we-heater bugcinwa kwiqondo lokushisa elijikeleze iCurie (ngokuqhelekileyo i-250 ° C).phezulu naphantsi), ukwenzela ukuba ugweme isiganeko "sobomvu" phezu kombane wokufudumeza izifudumezi zombane, ezingayi kubangela ukutshisa, imililo kunye nezinye iingozi ezifihliweyo.
Iqulethwe ngamashiti e-aluminiyam asusa ubushushu, iityhubhu ze-aluminium, ii-conductive sheets, iifilimu ezikhuselayo, ii-PTC zokufudumeza amaphepha, i-nickel-plated copper electrode terminals kunye ne-high-temperature yeplastiki ye-electrode sheaths.Ngenxa yokusetyenziswa kwe-press-fit heat sinks, le mveliso iphucula izinga lokutshatyalaliswa kobushushu kwaye ithathela ingqalelo ngokupheleleyo izinto ezahlukeneyo zokushisa kunye nombane we-PTC yokufudumeza into ngexesha lokusebenza.Inamandla okudibanisa okuqinileyo, i-conductivity egqwesileyo ye-thermal kunye nokusebenza kokutshatyalaliswa kobushushu, ukusebenza kakuhle okuphezulu kunye nokuthembeka.Olu hlobo lwe-heater ye-PTC luneenzuzo zokuchasana kwe-thermal encinci kunye nokusebenza kakuhle kokutshintsha kobushushu.Bubushushu obuzenzekelayo obuzenzekelayo kunye nesifudumezi sombane esigcina amandla.
Umgaqo wesifudumezi se-PTC Ukufudumeza rhoqo kwe-PTC thermistor ineempawu zokufudumeza rhoqo.Umgaqo-siseko kukuba emva kokuba i-thermistor ye-PTC inikwe amandla, iyazitshisa kwaye ixabiso lokumelana lingena kwindawo yenguqu.Ubushushu bomphezulu wobushushu obungaguqukiyo bokufudumeza i-PTC thermistor iya kugcina ixabiso elingaguqukiyo.Ubushushu bunxulumene kuphela nobushushu beCurie be-PTC thermistor kunye nombane osetyenziswayo, kwaye akukho nto yakwenza nobushushu be-ambient.
