1. Chidule cha kasamalidwe ka matenthedwe a cockpit (ma air conditioning pamagalimoto)
Makina owongolera mpweya ndiye chinsinsi chowongolera kutentha kwagalimoto.Onse awiri dalaivala ndi okwera amafuna kutsata chitonthozo cha galimoto.Ntchito yofunikira ya air conditioner yagalimoto ndikupangitsa kuti chipinda chokwera anthu chikhale choyendetsa bwino posintha kutentha, chinyezi ndi liwiro la mphepo m'chipinda chokwera galimotoyo.ndi malo okwera.Mfundo ya choyatsira mpweya wagalimoto ndi kuziziritsa kapena kutentha kutentha mkati mwagalimoto kudzera mu mfundo ya thermophysical ya mayamwidwe a evaporative kutentha ndi kutulutsa kutentha kwa condensation.Kutentha kwakunja kukakhala kochepa, mpweya wotentha ukhoza kuperekedwa ku kanyumbako kuti dalaivala ndi okwera asamve kuzizira;kunja kukakhala kutentha kwambiri, mpweya wochepa kwambiri ukhoza kuperekedwa ku kanyumbako kuti dalaivala ndi okwera amve ozizira.Chifukwa chake, chowongolera mpweya chagalimoto chimakhala ndi gawo lofunikira kwambiri pakuwongolera mpweya m'galimoto komanso chitonthozo cha omwe akukhalamo.
1.1 Makina owongolera mpweya wamagalimoto amagetsi atsopano ndi mfundo yogwirira ntchito
Chifukwa zida zoyendetsera magalimoto amagetsi atsopano ndi magalimoto amtundu wamafuta ndizosiyana, ma air-conditioning compressor amagalimoto amafuta amayendetsedwa ndi injini, ndipo air-conditioning compressor yamagetsi atsopano amayendetsedwa ndi mota, motero mpweya wowongolera mpweya. kompresa pamagalimoto atsopano amphamvu sangathe kuyendetsedwa ndi injini.Compressor yamagetsi imagwiritsidwa ntchito kukakamiza firiji.Mfundo yaikulu ya magalimoto amagetsi atsopano ndi yofanana ndi magalimoto amtundu wamafuta.Imagwiritsa ntchito condensation kutulutsa kutentha ndi kuwuka kuti itenge kutentha kuziziritsa chipinda chokwera.Kusiyana kwake ndikuti kompresa imasinthidwa kukhala yamagetsi yamagetsi.Pakadali pano, kompresa ya mpukutu imagwiritsidwa ntchito kwambiri kukakamiza firiji.
1) Makina otenthetsera a semiconductor: Chotenthetsera cha semiconductor chimagwiritsidwa ntchito kuziziritsa ndi kutenthetsa ndi zinthu za semiconductor ndi ma terminals.M'dongosolo lino, thermocouple ndiye chigawo choyambirira cha kuziziritsa ndi kutentha.Lumikizani zida ziwiri za semiconductor kuti mupange thermocouple, ndipo pakangogwiritsidwa ntchito mwachindunji, kusiyana kwa kutentha ndi kutentha kumapangidwa pa mawonekedwe kuti mutenthetse mkati mwa kanyumbako.Ubwino waukulu wa kutentha kwa semiconductor ndikuti imatha kutentha kanyumba mwachangu.Choyipa chachikulu ndikuti kutentha kwa semiconductor kumawononga magetsi ambiri.Kwa magalimoto amphamvu atsopano omwe amafunikira kutsata ma mileage, zovuta zake ndizowopsa.Chifukwa chake, sichingakwaniritse zofunikira zamagalimoto atsopano amagetsi pakupulumutsa mphamvu zama air conditioners.Ndikofunikiranso kwambiri kuti anthu azichita kafukufuku wa njira zotenthetsera za semiconductor ndikupanga njira yotenthetsera ya semiconductor yothandiza komanso yopulumutsa mphamvu.
2) Positive Temperature Coefficient(PTC) kutentha kwa mpweya: Chigawo chachikulu cha PTC ndi thermistor, chomwe chimatenthedwa ndi waya wotentha wamagetsi ndipo ndi chipangizo chomwe chimasintha mwachindunji mphamvu yamagetsi kukhala mphamvu ya kutentha.Makina otenthetsera mpweya wa PTC ndikusintha mpweya wotentha wagalimoto yamoto wamba kukhala chotenthetsera mpweya cha PTC, kugwiritsa ntchito fani kuthamangitsa mpweya wakunja kuti utenthedwe kudzera mu chotenthetsera cha PTC, ndikutumiza mpweya wotentha mkati mwa chipindacho. kutenthetsa chipinda.Imagwiritsa ntchito magetsi mwachindunji, kotero kuti mphamvu zogwiritsira ntchito magalimoto atsopano zimakhala zazikulu pamene chotenthetsera chimayatsidwa.
3) Kutentha kwamadzi kwa PTC:Kutentha kozizira kwa PTC, monga kutentha kwa mpweya wa PTC, kumatulutsa kutentha pogwiritsa ntchito magetsi, koma makina otentha ozizira amayamba kutenthetsa choziziritsa kukhosi ndi PTC, amatenthetsa choziziritsa kuzizira mpaka kutentha kwina, kenako amapopera choziziritsa kukhosi mu mpweya wotentha, amasinthanitsa kutentha. ndi mpweya wozungulira, ndipo fani imatumiza mpweya wotentha m'chipindamo kuti utenthetse kanyumba.Kenako madzi ozizira amatenthedwa ndi PTC ndikubwezeretsanso.Makina otenthawa ndi odalirika komanso otetezeka kuposa kuziziritsa mpweya kwa PTC.
4) Pampu yotenthetsera mpweya: Mfundo yapampu yotenthetsera mpweya ndi yofanana ndi yachikhalidwe yamagalimoto yamagalimoto, koma chotenthetsera chopopera chimatha kuzindikira kutembenuka kwa kutentha kwanyumba ndi kuziziritsa.
2. Chidule cha kayendetsedwe ka kutentha kwamagetsi
Thekasamalidwe ka matenthedwe amagetsi amagetsilagawidwa mu kasamalidwe ka matenthedwe kachitidwe ka mphamvu zamagalimoto amtundu wamafuta komanso kasamalidwe ka matenthedwe amagetsi amagetsi atsopano.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 makina oziziritsira injini.Kutentha kopitilira 30% mumayendedwe agalimoto kumafunika kumasulidwa ndi dera loziziritsa injini kuti injini isatenthedwe kwambiri pakalemedwe kake.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 yamagalimoto amphamvu atsopano Kutentha koyenera kogwira ntchito 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.
