Claims

[Claims for Utility Model Registration] In a laminated heat exchanger configured by alternately stacking a large number of core units and fins in which 11 pairs of core plates are joined to each other to form refrigerant passages inside, the heat exchanger The refrigerant inlet and outlet joints of the container are formed integrally with the core plate, and each joint is approximately perpendicular to both the refrigerant passage and the communication port formed in each core plate, and the opening end thereof is in the air blowing direction. Or a stacked heat exchanger characterized by being arranged facing the opposite side. 2. A utility model registration request characterized in that the bulge portion of the outer core plate forming the refrigerant inlet and outlet joint portions on the side without the joint portion is made flatter than the bulge portions of other core plates. A laminated heat exchanger according to scope 1. 3. Utility model registration claim 1, characterized in that the opening area of the refrigerant passage of the core unit in which the refrigerant inlet and outlet joint portions are formed is smaller than the opening area of the opening ends of the refrigerant passages of other core units. Stacked heat exchanger as described in section. 4. The laminated heat exchanger according to claim 1 or 2, wherein the refrigerant passage cross-sectional area of the refrigerant inlet and outlet joint portions is gradually reduced along the blowing direction.
