Komabe, ngati kutentha kwa injini kukakwera pamwamba pa kutentha kwa makinawo, chotenthetsera chimakhala chotanganidwa kwambiri, motero chimakoka mpweya wambiri wozungulira kudzera pa rediyeta yagalimotoyo, yomwe imathandiza kuteteza kapena kutsitsa kutentha kwa choziziritsira injini kufika pamlingo wovomerezeka.
Chiwombankhanga cha fan chikhoza kuyendetsedwa ndi lamba ndi pulley kapena mwachindunji ndi injini ikayikidwa pa crankshaft ya injini. Pali mitundu iwiri ya mafani a mafani: clutch ya viscous fan (clutch yamafuta a silicone) ndi clutch yamagetsi yamagetsi. mafuta fan clutch pamsika.
Silicone fan fan clutch, yokhala ndi mafuta a silicone ngati sing'anga, pogwiritsa ntchito mawonekedwe apamwamba amafuta a silicone kuti atumize torque. Kutentha kwa mpweya kumbuyo kwa radiator kumagwiritsidwa ntchito kuwongolera kudzipatula ndikuchitapo kanthu kwa fan clutch kudzera pa sensa ya kutentha. Kutentha kukakhala kotsika, mafuta a silicone samayenda, chowotcha cha fan chimalekanitsidwa, kuthamanga kwa mafani kumachepetsedwa, makamaka idling. Kutentha kukakhala kokwera, kukhuthala kwa mafuta a silikoni kumapangitsa kuti cholumikizira cha fan chiphatikizire kuti mafani azitha kugwirira ntchito limodzi kuwongolera kutentha kwa injini.
G&W Itha Kupereka zowongolerera zamafuta opitilira 300 a SKU a silikoni ndi zowongola zamagetsi zamagalimoto onyamula anthu otchuka aku Europe, Asia ndi America ndi magalimoto ogulitsa: AUDI, BMW, VW, FORD, DODGE, HONDA, LAND ROVER, TOYOTA etc, ndipo amapereka 2 Zaka chitsimikizo.
