Claims

[Scope of utility model registration request]

It has a pair of elongated plates 1 and 2, and the entire periphery of at least one of the plates 1 and a portion extending parallel to the longitudinal direction of the plate 1 with only one end connected to the center of the short side of the periphery are erected. By raising the pair of plates 1 and 2 liquid-tightly to each other at the raised portion, a flat U-shaped flow path is formed inside, and a pair of plates are formed at both ends of the U-shaped flow path. In a stacked heat exchanger in which elements 4 are formed by forming communicating holes 3, a plurality of elements 4 are stacked in the thickness direction, and the communicating holes 3 are connected to each other in the stacking direction.
, 2 are formed with a large number of grooves spaced parallel to each other and inclined in the longitudinal direction, and these grooves form convex stripes on the outer surfaces of the plates 1 and 2. and the inclination directions of the respective grooves of the pair of opposing plates 1 and 2 and the inclination directions of the protrusions of each of the adjacent elements 4 and 4 are formed to intersect with each other, and The protrusions of each element 4,4 are in contact with each other at the intersection and fixed by brazing, and the outer circumference is rectangular by being in contact with the flat surface in the flow path except for the bent portion of the U-shaped flow path. A laminated heat exchanger characterized in that a pair of inner fins 5 are fixed by brazing.
