Kutulutsa kwa fan ndi mtundu wamtundu, womwe umatanthawuza mtundu wamtundu womwe umagwiritsidwa ntchito ndi fani ya radiator yoziziritsa mpweya.
Muukadaulo wamakina, pali mitundu yambiri ya mayendedwe, koma pali mitundu yowerengeka yokha yomwe imagwiritsidwa ntchito pazinthu zama radiator: zonyamula manja pogwiritsa ntchito kukangana kotsetsereka, mayendedwe a mpira pogwiritsa ntchito kugundana, ndi kusakaniza kwa mitundu iwiri ya mayendedwe.M'zaka zaposachedwa, opanga ma radiator akuluakulu adayambitsa ukadaulo watsopano wa ma bearings, monga maginito maginito, mafunde amadzi, maginito core bearings, ndi ma hinge bearings..Ma radiator wamba oziziritsidwa ndi mpweya makamaka amagwiritsa ntchito ma bere opaka mafuta ndi mayendedwe a mpira.
Ma bearings okhala ndi mafuta ndi ma fani a manja omwe amagwiritsa ntchito kugwedezeka.Mafuta odzola amagwiritsidwa ntchito ngati mafuta komanso ochepetsera kukoka.Pogwiritsidwa ntchito koyamba, phokoso la ntchito ndi lochepa ndipo mtengo wopangira umakhalanso wotsika.Komabe, kunyamula kotereku kumavala mozama, ndipo moyo wake wautumiki umakhala kumbuyo kwa mayendedwe a mpira.Komanso, ngati kunyamula kwamtunduwu kumagwiritsidwa ntchito kwa nthawi yayitali, chifukwa cha chisindikizo chamafuta (ndikosatheka kugwiritsa ntchito chisindikizo chamafuta apamwamba kwambiri pazinthu zama radiator zamakompyuta, nthawi zambiri ndi chisindikizo chamafuta wamba), mafuta opaka mafuta. idzasintha pang'onopang'ono, ndipo fumbi lidzalowanso m'chifaniziro, kuchititsa fani Kuthamanga kumakhala pang'onopang'ono, phokoso likuwonjezeka ndi mavuto ena.Pazifukwa zazikulu, mawonekedwe a fan omwe amapangidwa chifukwa cha kuvala amatha kuyambitsa kugwedezeka kwakukulu.Ngati izi zikuwoneka, mwina mutsegule chisindikizo chamafuta kuti muwonjezere mafuta, kapena muchotse ndikugula chowotcha chatsopano.
Mpira wonyamulira umasintha kachitidwe kakukangana kayenyedwe kake, kutengera kukangana kozungulira, komwe kumachepetsa kwambiri kukangana pakati pa malo onyamula, kumapangitsa moyo wautumiki wa mafani, motero kumatalikitsa moyo wautumiki wa radiator.Choyipa chake ndi chakuti njirayi ndi yovuta kwambiri, yomwe imayambitsa kuwonjezeka kwa mtengo ndi phokoso logwira ntchito.
