PROBLEM TO BE SOLVED: To provide a gas cooler high in heat exchanging capacity. SOLUTION: A first projected wall 133 projected toward one end side in the laminating direction is formed on an end part of a laminated plate 131 on one side out of a set of the laminated plates 131, 132, a second projected wall 134 projected toward the other end side in the laminating direction is formed on an end part of the laminated plate 132 on the other side, and both of the projected walls 133, 134 are brazed on surfaces 133a, 134a in parallel with the laminating direction. Consequently, as it is possible to secure a sufficient connecting area (connecting strength) without forming a surface orthogonal with the laminating direction D by bending a part of the laminated plate, it becomes possible to make a connecting outer wall surface of a gas cooler into a flat surface and it is possible to easily braze and connect a joint block. |
