Claims

[Scope of utility model registration request]

A plate-shaped tube element having a refrigerant passage inside by stacking two dish-shaped core plates each having a large number of protruding ribs on the inner surface facing each other with the ribs inside and joining them at the peripheral end. In a stacked heat exchanger in which a plurality of tube elements are stacked in the thickness direction with fins interposed between them, the ribs of the core plate are oriented obliquely to the refrigerant flow direction. The ribs of both core plates are arranged in a row at a predetermined interval in the refrigerant flow direction and the direction orthogonal to the refrigerant flow direction, and the mutual positional relationship between the ribs of both core plates in the overlapping state is the same as that of the adjacent ribs in the refrigerant flow direction of one core plate. The ribs of the other core plate are present so as to span the adjacent ends, and the refrigerant passages within the tube element are formed into a large number of meandering passages without ribs and between each meandering passage. 1. A laminated heat exchanger characterized in that it has a large number of bypass passages in which only ribs on one side are present.
