Investigation of the geometrical structure of louvered fins in fin-tube heat exchangers for determining the minimum distance of the headers

Numerical investigation of louver edges effect on the performances of louvered fin compact heat exchanger

“…The air-cooled compact heat exchangers with louver fin are extensively used in vehicles radiators since it is the most efficient and advanced heat transfer fin surface [ [1] , [2] , [3] , [4] ]. The heat transfer between the louver fin surface and the air is what drives the predominant heat transfer by interrupting or breaking up the flow of air and creating thin boundary layers, which lowers the thermal resistivity and increases the heat dissipation [ [5] , [6] , [7] , [8] ]. Increasing the heat transfer rate, decreasing the pressure drop, and compacting the volumes are the basic design consideration for increasing the performance of the heat exchanger [ 9 ].…”
