Datang itanga Extruded Fin Tubes ikorwa nuburyo bukonje bwo kuzenguruka.Fin ya Extruded Fin ikozwe mumiyoboro ya aluminiyumu yo hanze ifite uburebure bunini bwurukuta, igahuzwa hejuru yigitereko cyimbere.Imiyoboro yombi isunikwa mu mbaho eshatu hamwe na disikuru zizunguruka zifata neza cyangwa zisohora aluminiyumu hejuru no hanze y'ibikoresho bya muff mu buryo bwa spiral mu gikorwa kimwe.Inzira yo gukuramo ikomera amababa kandi ikabuza guhuza ibyuma bidasa kumuzi wanyuma.Ubuso bwo hanze bugaragara ni aluminium kandi ntamunota uhari hagati yimisozi yegeranye aho ubuhehere bushobora kwinjira.Ibi bitanga umusaruro mwiza uteganijwe mugihe ukoresheje ubuso bwagutse bwo kohereza ubushyuhe.Mugihe cyo kurangiza, uruganda rukomeye rukora hagati ya aluminiyumu yatunganijwe neza hamwe nigitereko cyimbere cyicyuma gikenewe.
