Recently, works on compact heat exchangers have sparked interest amongst heat exchanger manufacturers to develop the compact heat exchangers with enhanced thermal performance in comparison to conventional ones. The purpose of this study is to design more efficient fin than commonly used louvered fin on the basis of same core size. Cooling capacity of louvered fin of conventional radiator is numerically analyzed and the performance is compared with that of the designed fin. Simulations were performed for different louver pitches with 0.9, 1.4 ㎜. In conclusion, cooling capacity of designed fin with 0.9 ㎜ louver pitch is increased more than 7% compared with the conventional fin even though the air side pressure drop increased.
