Chidule cha Kasamalidwe ka Matenthedwe M'magalimoto Amagetsi Amagetsi

Kuwongolera kwamafuta amagetsi amagetsi kumagawika m'matenthedwe amtundu wamagalimoto amtundu wamafuta komanso kasamalidwe kamafuta amagetsi atsopano amagetsi.Tsopano kasamalidwe ka matenthedwe amagetsi amtundu wamafuta amafuta ndi okhwima kwambiri.Galimoto yamafuta yachikhalidwe imayendetsedwa ndi injini, motero kasamalidwe ka injini ya Thermal ndiye cholinga cha kayendetsedwe kazambiri zamagalimoto.Kuwongolera kutentha kwa injini kumaphatikizapo kuzizira kwa injini.Kutentha kopitilira 30% kwamagalimoto kumafunika kumasulidwa ndi dera loziziritsa injini kuti injini isatenthedwe kwambiri pogwira ntchito yolemetsa kwambiri.Chozizira cha injini chimagwiritsidwa ntchito kutenthetsa kanyumba.

Malo opangira mphamvu zamagalimoto amtundu wamafuta amapangidwa ndi mainjini ndi kutumizira magalimoto amtundu wamafuta, pomwe magalimoto amagetsi atsopano amapangidwa ndi mabatire, ma mota, ndi zowongolera zamagetsi.Njira zoyendetsera kutentha kwa awiriwa zasintha kwambiri.Batire yamagetsi yamagetsi atsopano Kutentha kwanthawi zonse ndi 25 ~ 40 ℃.Choncho, kasamalidwe ka kutentha kwa batri kumafuna kuti zonse zikhale zotentha ndi kuzitaya.Panthawi imodzimodziyo, kutentha kwa injini sikuyenera kukhala kokwera kwambiri.Ngati kutentha kwa injini ndikokwera kwambiri, kumakhudza moyo wautumiki wa injiniyo.Chifukwa chake, injiniyo imayeneranso kuchitapo kanthu pakuchotsa kutentha pakagwiritsidwe ntchito.Chotsatirachi ndi chiyambi cha kayendetsedwe ka kutentha kwa batri ndi kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe kake.

Power battery thermal management system

The matenthedwe kasamalidwe batire mphamvu batire makamaka ogaŵikana mpweya kuzirala, madzi kuzirala, gawo kusintha zinthu kuzirala ndi kutentha chitoliro kuzirala zochokera zosiyanasiyana kuzirala.Mfundo ndi machitidwe a njira zosiyanasiyana zozizira ndizosiyana kwambiri.

1) Kuziziritsa kwamphamvu kwa batire: batire paketi ndi mpweya wakunja umapangitsa kusinthana kwa kutentha kudzera mukuyenda kwa mpweya.Kuzizirira kwa mpweya nthawi zambiri kumagawika kuziziritsa kwachilengedwe komanso kuziziritsa mokakamiza.Kuzizira kwachilengedwe ndi pamene mpweya wakunja umazizira batire pamene galimoto ikuyenda.Kuziziritsa mpweya mokakamiza ndikokhazikitsa chofanizira kuti chiziziziritse mokakamizidwa ndi paketi ya batri.Ubwino wa kuziziritsa mpweya ndi mtengo wotsika komanso kugwiritsa ntchito kosavuta kwamalonda.Zoyipa zake ndi kuchepa kwa kutentha kwapang'onopang'ono, kuchuluka kwa malo okhala, komanso vuto lalikulu laphokoso.(PTC Air Heater)

2) Kuzizira kwamadzi a batri: kutentha kwa paketi ya batri kumachotsedwa ndi kutuluka kwamadzimadzi.Popeza kutentha kwamadzimadzi ndikokulirapo kuposa mpweya, kuziziritsa kwa kuziziritsa kwamadzi kumakhala bwinoko kuposa kuziziritsa kwa mpweya, komanso liwiro loziziritsa limakhalanso mwachangu kuposa kuzirala kwa mpweya, komanso kugawa kutentha pambuyo pakutentha kwa mpweya. batire paketi ndi yunifolomu.Choncho, kuzirala kwamadzimadzi kumagwiritsidwanso ntchito kwambiri pamalonda.(PTC Coolant Heater)

3) Kuzizira kwa zipangizo zosinthira gawo: Zida zosinthira gawo (PhaseChangeMaterial, PCM) zimaphatikizapo parafini, mchere wa hydrated, mafuta acids, ndi zina zotero, zomwe zimatha kuyamwa kapena kutulutsa kutentha kwakukulu kobisika pamene kusintha kwa gawo kukuchitika, pamene kutentha kwawo kumakhalabe. zosasinthika.Chifukwa chake, PCM ili ndi mphamvu yayikulu yosungira mphamvu zotentha popanda kugwiritsa ntchito mphamvu zowonjezera, ndipo imagwiritsidwa ntchito kwambiri pakuziziritsa kwa batri pazinthu zamagetsi monga mafoni am'manja.Komabe, kugwiritsa ntchito mabatire amagetsi amagetsi kudakali m'boma lofufuza.Zida zosinthira gawo zimakhala ndi vuto la kutsika kwamafuta otsika, zomwe zimapangitsa kuti PCM igwirizane ndi batire isungunuke, pomwe mbali zina sizisungunuka, zomwe zimachepetsa kutengerako kutentha kwa dongosololi ndipo sizoyenera mphamvu zazikuluzikulu. mabatire.Ngati mavutowa atha kuthetsedwa, kuziziritsa kwa PCM kudzakhala njira yothetsera kutentha kwa magalimoto atsopano.

4) Kuzizira kwa chitoliro cha kutentha: Chitoliro cha kutentha ndi chipangizo chokhazikitsidwa ndi kusintha kwa kutentha kwa gawo.Chitoliro chotentha ndi chidebe chosindikizidwa kapena chitoliro chosindikizidwa chodzazidwa ndi sing'anga yogwira ntchito / yamadzimadzi (madzi, ethylene glycol, kapena acetone, etc.).Chigawo chimodzi cha chitoliro cha kutentha ndi mapeto a evaporation, ndipo mapeto ena ndi mapeto a condensation.Sizingangotengera kutentha kwa paketi ya batri komanso kutenthetsa paketi ya batri.Pakali pano ndi njira yabwino kwambiri yoyendetsera batire yamagetsi.Komabe, ikufufuzidwabe.

5) Kuzirala kwachindunji kwa refrigerant: kuzirala kwachindunji ndi njira yogwiritsira ntchito mfundo ya R134a refrigerant ndi mafiriji ena kuti asungunuke ndi kuyamwa kutentha, ndikuyika evaporator ya air conditioning system mu bokosi la batri kuti muziziritsa mwamsanga bokosi la batri.Dongosolo lozizira lachindunji lili ndi kuzizira kwambiri komanso kuzizira kwakukulu.
