FIN FOR A HEAT EXCHANGER, CAPABLE OF INCREASING HEAT TRANSFER AND DECREASING AIR PRESSURE DROP

摘要

PURPOSE: A fin for a heat exchanger is provided to increase heat transfer and decrease air pressure drop since louvers of a fin for a heat exchanger are formed to have various tilt angles.;CONSTITUTION: A fin(4) for a heat exchanger has a wrinkled structure, which has a flat part and a curved part. A plurality of louvers are formed on the flat part of the fin and an air path is formed between the louvers. The louvers are divided into two or more louver units(L1,L2), each of which consists of a plurality of louvers. Tilt angle of a louver of one louver unit is different from that of a neighboring louver unit.;COPYRIGHT KIPO 2011
