Kodi intercooler yagalimoto ndi chiyani
The intercooler m'galimoto ndi chipangizo chothandizira kutentha kwa injini za turbocharged, zomwe zimagwiritsidwa ntchito kuziziritsa mpweya wotentha kwambiri pambuyo pa turbocharging kuti injini igwire bwino ntchito komanso mphamvu.
Kutanthauzira koyambira ndi ntchito
The Intercooler, chigawo chachikulu cha injini yacharged monga injini ya turbocharged kapena supercharged, imayikidwa pakati pa supercharger ndi manifold ambiri. Ntchito yake yaikulu ndikuchepetsa kutentha kwa mpweya wochuluka kwambiri. Ntchito zake zazikulu ndi izi:
Youdaoplaceholder0 Kuziziritsa kwa mpweya wotentha : Pakuchulukirachulukira, mpweya umaponderezedwa, zomwe zimapangitsa kutentha kwake kukwera (mpaka 200 ° C). The intercooler amachepetsa kutentha kwa osiyanasiyana (nthawi zambiri 50-60 ° C) kudzera dissipation kutentha, kuteteza kwambiri matenthedwe katundu pa injini.
Youdaoplaceholder0 Kupititsa patsogolo kuyaka kwachangu : Mpweya wotsika kwambiri umakhala ndi kachulukidwe kakang'ono, komwe kumawonjezera kuchuluka kwamafuta komanso kumathandizira kuyaka kwathunthu kwamafuta, potero kumawonjezera mphamvu (pa 10 ° C iliyonse kutsika kwa kutentha kwa mpweya wopanikizika, mphamvu imawonjezeka ndi 3% -5%).
Youdaoplaceholder0 Chepetsani kuphulika ndi kutulutsa mpweya : Mpweya wotentha kwambiri umakonda kuyambitsa kuphulika, pomwe kuziziritsa kumachepetsa kutulutsa kwa NOx ndi zowononga zina.
Type ndi momwe zimagwirira ntchito
Intercoolers amagawidwa m'njira ziwiri zazikulu zozizirira:
Youdaoplaceholder0 Air-cooled : Imagwiritsa ntchito mpweya wopangidwa ndi galimoto pamene ikuyenda kuti iwononge kutentha. Nthawi zambiri imayikidwa kutsogolo kwa galimoto kapena pafupi ndi radiator. Ili ndi dongosolo losavuta komanso lotsika mtengo, koma limakhudzidwa kwambiri ndi kutentha kozungulira.
Youdaoplaceholder0 Woziziritsidwa ndi madzi : Imazizira pozungulira injini yozizirira, ikupereka kutentha kosalekeza. Ndizoyenera magalimoto oyendetsa malo (monga ena apamwamba), koma zotsatira zoziziritsa nthawi zambiri zimakhala zochepa kusiyana ndi mpweya wozizira.
Zida ndi Kapangidwe
Youdaoplaceholder0 Material : Nthawi zambiri amapangidwa ndi aloyi ya aluminiyamu chifukwa cha kulemera kwake komanso kusinthasintha kwabwino kwa matenthedwe.
Mapangidwe a Youdaoplaceholder0 : Mkati mwake muli machubu owundana ndi zipsepse, zomwe zimayamwa ndikuchotsa kutentha pamene mpweya umayenda m'machubu.
Zolemba zokonza ndi kusintha
Youdaoplaceholder0 Kuyeretsa : Muzitsuka fumbi lakunja pafupipafupi (peŵani kupopera mbewu mankhwalawa ndi mfuti yamadzi yothamanga kwambiri) ndikuyang'ana mkati kuti mutseke.
Malingaliro osintha a Youdaoplaceholder0 :
Sankhani kukula koyenera kuti muzitha kuzirala bwino komanso kutaya mphamvu;
Mapaipi ayenera kufupikitsidwa momwe angathere ndikukhala mowongoka kuti achepetse kukana kwa mpweya.
Chitoliro cha chitoliro chotuluka chiyenera kukhala chokulirapo pafupifupi 10% kuposa chitoliro cholowera kuti chiwonjezeke bwino.
Zochitika zovomerezeka
Ma injini okhala ndi turbocharged okha ndi omwe amafunikira kukhala ndi ma intercoolers, pomwe ma injini omwe amafunidwa mwachilengedwe safuna chipangizochi chifukwa cha kutentha kochepa kwa mpweya.
Chepetsani kutentha kwa mpweya woponderezedwa kuti muwonjezere mphamvu ndi mphamvu ya injini
Ntchito yayikulu: Kuziziritsa mpweya wopanikizika
The intercooler ndi gawo lofunika kwambiri la injini za turbocharged kapena supercharged, zomwe zili pakati pa turbocharger ndi ma intake manifold. Ntchito yake yayikulu ndikuziziritsa mpweya wotentha kwambiri woponderezedwa ndi turbocharger (yotentha mpaka 80-200 ℃), ndikuchepetsa kutentha kwa mpweya kudzera pakusinthanitsa kutentha, potero:
Youdaoplaceholder0 Wonjezerani kachulukidwe ka mpweya : Ukazizira, kuchuluka kwa mpweya kumachepa ndipo mpweya wa okosijeni umachuluka, zomwe zimapangitsa kuti injini igwire bwino ntchito.
Youdaoplaceholder0 Wonjezerani mphamvu zotuluka : Zoyeserera zikuwonetsa kuti pakutsika kulikonse kwa 10 ° C kutentha kwa mpweya wopanikizika, mphamvu ya injini imakwera ndi 3% mpaka 5%.
Sinthani magwiridwe antchito a injini ndi kudalirika
Youdaoplaceholder0 Chepetsani kutentha : Mpweya wotentha kwambiri umawonjezera kupsinjika kwa kutentha muchipinda choyaka injini. The intercooler kuziziritsa pansi kuteteza kugogoda, yamphamvu mutu deformation ndi mavuto ena.
Youdaoplaceholder0 Kutsika kwa mpweya : Mpweya woziziritsa umayaka kwambiri, kumachepetsa kutulutsa kwa nitrogen oxide (NOx) ndi utsi wakuda.
Youdaoplaceholder0 Limbikitsani kuchuluka kwamafuta : Mpweya wozizira umasakanikirana mofanana ndi mafuta, umathandizira kuyaka bwino ndikuchepetsa kugwiritsa ntchito mafuta.
Kusintha kwapadera kwachilengedwe
M'madera okwera kwambiri, ma intercoolers amalola kugwiritsa ntchito ma compressor omwe ali ndi chiŵerengero chapamwamba cha kuthamanga kuti athe kubwezera kutaya mphamvu chifukwa cha okosijeni wochepa kwambiri komanso kumapangitsa kuti galimotoyo ikhale yosinthika.
Mitundu ndi mitundu yosiyanasiyana
Youdaoplaceholder0 Air-cooled (air-air cooler) : Nthawi zambiri amagwiritsidwa ntchito m'magalimoto onyamula anthu, amaziziritsa mpweya wopanikizika ndi mpweya wakunja. Ili ndi dongosolo losavuta koma limakhudzidwa kwambiri ndi kutentha kozungulira.
Youdaoplaceholder0 Woziziritsidwa ndi madzi : Imachotsa kutentha kudzera mu choziziritsira, ndiyothandiza kwambiri koma yokwera mtengo kwambiri, ndipo imagwiritsidwa ntchito kwambiri pamamodeli ochita bwino kwambiri.
Youdaoplaceholder0 Overhead intercooler (monga Subaru Impreza) : imafupikitsa sitiroko yomwe imamwa koma imakhala ndi mphamvu yochepetsera kutentha pang'ono, ndipo imakhala yabwinoko pakulinganiza mphamvu ndi kugwiritsa ntchito mafuta.
Youdaoplaceholder0 Kulephera kukhudzidwa : Ngati intercooler itayikira, ipangitsa mphamvu yocheperako, kuchuluka kwamafuta, komanso kuvala mwachangu chifukwa cha tinthu tating'ono tolowa mu silinda.
Ngati kukhathamiritsa kwina kwapangidwe kumafunika, chidwi chiyenera kulipidwa pamiyezo yazinthu (monga GB 3880 ya mbale za aluminiyamu aloyi) ndi zofunikira pakuwongolera.
paNgati mukufuna kudziwa zambiri, pitilizani kuwerenga zolemba zina patsamba lino!
Chonde tiyimbireni ngati mukufuna zinthu zotere.
Malingaliro a kampani Zhuo Meng Shanghai Auto Co., Ltd. adadzipereka kugulitsa zida zamagalimoto za MG&750 zolandilidwa kugula.
