Claims

[Scope of utility model registration request]

A U-shaped recess is formed on one side of a metal plate having a pair of protrusions spaced apart from each other on one end edge, with both ends of the recess continuing to the edges of the pair of protrusions. At the same time, by stacking two metal plates in a set with their recesses facing each other and joining them liquid-tightly, a U-shaped folded flow path and this flow path are formed. and a pair of joints located at both ends of the element and protruding from the edge, and each joint of the plurality of elements is
Each element is inserted into a slit-shaped connection hole formed in the seat plate, and the outer peripheral surface of each joint part and the inner peripheral edge of each connection hole are liquid-tightly joined to each other, and fins are provided between adjacent elements. In a laminated heat exchanger, a tank plate is liquid-tightly fixed on the surface of the seat plate, the tank plate having a plurality of recesses formed on the side opposite to the plurality of elements in accordance with the collection of the connection holes. A small groove-shaped recess is formed in a part of the plate between adjacent recesses over the entire length of the gap, and at least one end of the small recess is opened to the peripheral edge of the tank plate. A laminated heat exchanger with the following characteristics:
