Claims

[Scope of utility model registration request]

By forming a U-shaped recess on one side of a metal plate, and forming a set of two metal plates, overlapping them in the middle with their recesses facing each other and joining them liquid-tightly, A laminated heat exchanger configured by having an element having a U-shaped folded passage, and having both ends of each folded passage of a plurality of elements communicate with a tank, and fins provided between adjacent elements. In this case, by fixing a partition wall in the middle of one tank, the inside of this one tank is divided into an inlet chamber and an outlet chamber, and the partition wall penetrates only one end wall of the one tank. A first pipe and a second pipe penetrating the one end wall and the partition wall are provided, one of the first pipe and the second pipe serving as an inlet pipe continuing to the fluid feed port, and the other pipe serving as an inlet pipe continuing to the fluid inlet. A stacked heat exchanger characterized by each function as an outlet pipe following a fluid outlet.
