Abstract: PURPOSE: A louver fin and a heat exchanger having the same are provided to increase amount of heat transfer and reduce a drop of air pressure by forming a dimple on a corrugated part and a flat part with changing a manufactured mold. CONSTITUTION: A heat exchanger comprises a body(110), a plurality of louvers(120), dimples(130), a louver fin(100), and a tube. The body is formed into a thin plate and comprises a corrugated part and a flat part. The louver is formed on each inclined plane. The dimple is protruded toward an inner side of the body from the corrugated part and the flat part. The dimple has a width along a depth of the corrugated part or the flat part of the body. The louver fin comprises the inclined plane which is gradually branched to a direct path of gas passing through the body. The tube is connected along the corrugated part and the flat part of the louver fin.
