Abstract: A heat exchanger including a plurality of fluid channel plates laminated on each other to form a cooling water fluid channel through which cooling water flows and an air fluid channel through which air flows. The fluid channel plates have a cooling water inlet hole through which the cooling water is introduced and a cooling water outlet hole through which the cooling water is discharged. Beads block the flow of the cooling water, protrude between the cooling water inlet hole and the cooling water outlet hole, are arranged to surround the periphery of the cooling water inlet hole and the cooling water outlet hole, and are spaced apart such that flow resistance of the cooling water decreases as a flow length of the cooling water increases, so that flow distribution of the cooling water can be uniform.
