STRUCTURE FOR FORMING LOUVER OF RADIATION FIN FOR HEAT EXCHANGER

摘要

PURPOSE: A structure for forming louver of radiation fin for heat exchanger is provided to make refrigerant pipes on a second row exchange heat equally to the refrigerant pipes on a first row by making flow of air concentrated on the refrigerant on the second row to improve efficiency of heat exchange. CONSTITUTION: A louver(13) is formed to be oval or rhombic so that a central part thereof is higher than both ends of the basic line so that air flowing through air passages formed by the louvers formed on radiation fins(12) flows mainly through the central part of the louver to make flowing air concentrated on refrigerant pipes(11') on a second row following the central part of the louver.
