PROBLEM TO BE SOLVED: To allow cooling water and oil to flow in respective passages evenly in core plates for a heat exchanger core provided with an inlet and an outlet for cooling water on one side of a bottom wall and an inlet and an outlet for oil on the opposite side of the bottom wall with respect to a plate centerline. SOLUTION: As for the core plates 8 for a heat exchanger core 13 for a laminated heat exchanger, many rectangular core plates 1 each having two hole flanges 3 and 4 on one side and two communication holes 5 and 6 on the other side, are laminated such that the side with the hole flanges 3 and 4 and the side with the communication holes 5 and 6 are positioned alternately to form cooling water passages 9 and oil passages 10 alternately. The core plates 8 are each provided with a swell 7 extending from one hole flange 3 to the other hole flange 3. COPYRIGHT: (C)2007,JPO&INPIT
