M'chilimwe chotentha kapena m'nyengo yozizira, mpweya woziziritsa magalimoto ndi wofunikira kwa ife okonda magalimoto, makamaka pamene mawindo achita chifunga kapena chisanu. Kuthekera kwa makina oziziritsa mpweya kuti achotse mpweya ndi kusungunuka mwachangu kumachita gawo lofunika kwambiri pachitetezo choyendetsa. Kwa magalimoto amagetsi, omwe alibe injini yamafuta, alibe gwero lotenthetsera, ndipo compressor ilibe mphamvu yoyendetsera injini kuti iziziritse. Ndiye magalimoto amagetsi enieni amapereka bwanji ntchito zoziziritsira mpweya ndi kutentha? Tiyeni tipeze.
01 Zigawo za Air Conditioning Cooling System
Zigawo za makina oziziritsira mpweya ndi izi: compressor yamagetsi, condenser, sensa yokakamiza, valavu yowonjezera yamagetsi, evaporator, mapaipi olimba a mpweya, mapayipi, ndi dera lowongolera.
Chokompressor:
Imalandira mpweya wozizira wochepa komanso wochepa ndipo imaupanikiza kukhala mpweya wozizira wotentha komanso wochepa. Pakapanikizika, momwe mpweya woziziritsira umakhalira sunasinthe, koma kutentha ndi kupanikizika kumawonjezeka nthawi zonse, ndikupanga mpweya wotentha kwambiri.
Chokondensa:
Kondensala imagwiritsa ntchito fani yoziziritsira yokha kuti ichotse kutentha kwa firiji yotenthetsera kwambiri komanso yothamanga kwambiri ku mpweya wozungulira, ndikuziziritsa firijiyo. Munjira imeneyi, firijiyo imasintha kuchoka pa mpweya kupita ku madzi, ndipo imakhala mu kutentha kwambiri komanso yothamanga kwambiri.
Valavu Yokulitsa:
Firiji yamadzimadzi yotentha kwambiri komanso yothamanga kwambiri imadutsa mu valavu yokulitsa kuti ichepetse kuthamanga kwa madzi isanalowe mu evaporator. Cholinga cha njirayi ndikuziziritsa ndikuchepetsa kupsinjika kwa madzi oziziritsa ndikuwongolera kuyenda kwa madzi kuti azitha kuziziritsa. Firiji ikadutsa mu valavu yokulitsa, imasintha kuchoka pamadzimadzi otentha kwambiri kupita kumadzi otentha kwambiri komanso otsika.
Chotulutsira mpweya:
Mpweya woziziritsa womwe umachokera ku valavu yokulitsa umayamwa kutentha kwakukulu kuchokera mumlengalenga wozungulira womwe uli mu evaporator. Panthawiyi, mpweya woziziritsa umasintha kuchoka pamadzi kupita ku mpweya woziziritsa womwe umachokera pamadzi. Kenako mpweyawu umalowetsedwa ndi compressor kuti ukhale wopanikizika kachiwiri.
Kuchokera pa mfundo yoziziritsira, makina oziziritsira mpweya m'magalimoto amagetsi ndi ofanana ndi magalimoto achikhalidwe ogwiritsira ntchito mafuta. Kusiyana kwakukulu kuli mu njira yoyendetsera makina oziziritsira mpweya. M'magalimoto achikhalidwe ogwiritsira ntchito mafuta, makina oziziritsira mpweya amayendetsedwa ndi pulley ya lamba la injini, pomwe m'magalimoto amagetsi, makina oziziritsira mpweya amayendetsedwa ndi magetsi kuti ayendetse injini, yomwe imayendetsa makina oziziritsira mpweya kudzera mu crankshaft.
02 Dongosolo Lotenthetsera Mpweya
Gwero lotenthetsera limapezeka makamaka kudzera mu kutentha kwa PTC (Positive Temperature Coefficient). Magalimoto amagetsi oyera nthawi zambiri amakhala ndi mitundu iwiri: PTC module yotenthetsera mpweya ndi PTC module yotenthetsera madzi. PTC ndi mtundu wa semiconductor thermistor, ndipo khalidwe lake ndilakuti kukana kwa zinthu za PTC kumawonjezeka pamene kutentha kukukwera. Pansi pa voltage yokhazikika, chotenthetsera cha PTC chimatentha mwachangu kutentha kochepa, ndipo pamene kutentha kukukwera, kukana kumawonjezeka, mphamvu yamagetsi imachepa, ndipo mphamvu zomwe PTC imadya zimachepa, motero zimasunga kutentha kokhazikika.
Kapangidwe ka Mkati mwa Gawo la PTC Yotenthetsera Mpweya:
Lili ndi chowongolera (kuphatikiza gawo loyendetsa la voltage yotsika/yokwera kwambiri), zolumikizira za waya zothamanga kwambiri/zotsika, filimu yoteteza kutentha ya PTC, silicone pad yoteteza kutentha, ndi chipolopolo chakunja, monga momwe zasonyezedwera pachithunzichi.
Module ya PTC yotenthetsera mpweya imatanthauza kukhazikitsa mwachindunji PTC pakati pa makina otenthetsera mpweya a kanyumba. Mpweya wa kanyumba umayendetsedwa ndi chofewetsera mpweya ndikutenthedwa mwachindunji ndi chotenthetsera cha PTC. Filimu yotetezera kutentha mkati mwa module ya PTC yotenthetsera mpweya imayendetsedwa ndi mphamvu yamagetsi yapamwamba ndipo imayendetsedwa ndi VCU (Vehicle Control Unit).
03 Kulamulira Makina Oziziritsira Mpweya a Magalimoto Amagetsi
VCU ya galimoto yamagetsi imasonkhanitsa zizindikiro kuchokera ku switch ya A/C, switch ya A/C pressure, kutentha kwa evaporator, liwiro la fan, ndi kutentha kwa mlengalenga. Pambuyo pokonza ndi kuwerengera, imapanga zizindikiro zowongolera, zomwe zimatumizidwa ku chowongolera mpweya kudzera mu basi ya CAN. Chowongolera mpweya chimayang'anira kuyatsa/kuzima kwa dera lamagetsi la compressor ya mpweya, monga momwe zasonyezedwera pachithunzichi.
Zimenezi zikumaliza chiyambi cha makina oziziritsira mpweya wa magalimoto amagetsi. Kodi mwapeza kuti n'zothandiza? Tsatirani Yiyi New Energy Vehicles kuti mudziwe zambiri zokhudza akatswiri omwe amagawana sabata iliyonse.
