Cross flow heat exchangers yog siv nyob rau hauv ntau yam kev siv. Mixed thiab unmixed cross flow exchangers tuaj yeem muaj npe raws li hom ntoo khaub lig ntws kub exchangers raws li cov fins siv nyob rau hauv lub system. Lwm lub npe rau lawv yog finned thiab unfinned. Daim duab hauv qab no qhia cov hom no.
Mixed Cross Flow Thaum tshav kub kub Exchangers
Hauv hom no, cov kua dej hla cov kav dej hauv lub plhaub sab, thiab cov dej ntws yog perpendicular mus rau cov kav dej. Lub tshav kub exchanger tsis muaj fins, raws li qhia nyob rau hauv daim duab. Peb tuaj yeem muaj turbulent flow nyob rau hauv hom no, thiab lub siab poob qis dua lwm qhov. Turbulent flow tuaj yeem ua rau kom cov cua sov hloov pauv ntau.
Unmixed Cross Flow Thaum tshav kub kub Exchangers
Nyob rau hauv lub unmixed cross flow heat exchangers, peb muaj fins nyob ib ncig ntawm cov kav dej los yog cais raws rau cov ntws mus hla cov kav dej. Kev siv cov fins tuaj yeem ua kom cov cua sov hloov pauv vim qhov nce hauv qhov chaw zoo ntawm cov cua sov. Ntawm qhov tsis sib xws, peb muaj kev poob siab loj dua hauv qhov system. Tsis tas li ntawd, qhov hnyav thiab tus nqi ntawm cov hom no nce ntxiv vim yog ntxiv fins rau qhov sib pauv.
