Claims

[Claims for Utility Model Registration] 1. It has a pair of elongated plates 1 and 2, and the entire periphery of at least one of the plates 1 and only one end are connected to the center of one longitudinal edge of the plate, and the longitudinal direction of the plate 1 is The pair of plates 1 are raised at the raised parts.
, 2 are joined to each other to form a flat U-shaped flow path inside, and a pair of communicating holes 3 are formed at both ends of the U-shaped flow path to form an element 4.
In a stacked heat exchanger in which a plurality of elements 4 are stacked in the thickness direction and the communication holes 3 are connected to each other in the stacking direction, A large number of grooves are formed on the inner surface side parallel to each other and inclined in the longitudinal direction, and on the outer surfaces of the plates 1 and 2, the grooves are formed as convex stripes. The inclination direction of each groove of the pair of plates 1 and 2, and the adjacent element 4,
The inclined directions of the protrusions of each of the elements 4 are formed to intersect with each other, and the protrusions of the elements 4 and 4 are in contact with each other at the intersection and fixed by brazing, and only the flat surface of the flow path is formed. A laminated heat exchanger characterized in that an inner fin 5 is brazed and fixed in contact with the fin. 2. According to claim 1, the curved portion in the flat flow path is reduced by making the interval between adjacent grooves in the U-shaped bent portion of the flow path smaller than that in the straight portion. Reduced flow path resistance.
