Radiator ili ndi chipinda cholowera madzi, chipinda chotulutsira madzi ndi poyambira radiator.Chozizirirapo chimayenda pakati pa radiator ndipo mpweya umadutsa pa radiator.Madzi ozizira otentha amazizira chifukwa amachotsa kutentha kwa mpweya, pamene mpweya wozizira umatentha chifukwa umatenga kutentha kuchokera ku ozizira.

Radiator ali ndi udindo woziziritsa madzi ozungulira.Chitoliro chake chamadzi ndi radiator nthawi zambiri zimapangidwa ndi aluminiyamu.Chitoliro chamadzi cha aluminiyamu chimapangidwa ndi mawonekedwe athyathyathya, ndipo radiator ndi malata.Imatchera khutu ku ntchito yochotsa kutentha.Mayendedwe oyika ndi perpendicular kwa kayendedwe ka mpweya.Yesetsani kuti kukana kwa mphepo kukhale kochepa komanso kuzizirira bwino kwambiri.Chozizirirapo chimayenda pakati pa radiator ndipo mpweya umadutsa pakati pa radiator.Choziziritsa chotentha chimazizira chifukwa chimachotsa kutentha kwa mpweya, ndipo mpweya wozizira umatentha chifukwa umatenga kutentha kuchokera ku choziziritsa, choncho radiator ndi kusinthana kutentha.

Zida zama radiator ndi ukadaulo wopanga zidakula mwachangu.Aluminiyamu radiator ali ndi ubwino woonekeratu muzinthu zopepuka.Pakatikati pa radiator yamtundu wa fin imakhala ndi machubu ambiri ozizirira ndi zipsepse.Machubu ambiri ozizirira amakhala ndi gawo la oblate kuti achepetse kukana kwa mpweya ndikuwonjezera malo otumizira kutentha.
Rediyeta pakati pawo pazikhala ndi malo okwanira kuti chozizirirapo chidutsemo, komanso malo oyendera mpweya wokwanira kuti mpweya wokwanira udutsemo kuti uchotse kutentha kochokera ku chozizirirapo kupita ku radiator.Panthawi imodzimodziyo, iyenera kukhala ndi malo okwanira kutentha kutentha kuti athe kusinthanitsa kutentha pakati pa chozizira, mpweya ndi kutentha kwakuya.
Radiyeta ya lamba wa chubu amapangidwa ndi kuwotcherera cholumikizira chamalata ndipo chitoliro chozizirira chimakonzedwa mosinthana.

Poyerekeza ndi fin radiator, malo otenthetsera kutentha kwa chubu ndi ma radiator amatha kukulitsidwa ndi 12% pamikhalidwe yomweyo.Kuonjezera apo, mzere woziziritsa umaperekedwa ndi louver ngati mabowo kuti asokoneze kayendedwe ka mpweya, kuti awononge mpweya wotuluka pamwamba pa mzere woziziritsa ndikuwongolera kutentha kwa kutentha.
