Claims

[Scope of utility model registration request]

At one end, a bulging inlet tank portion having a refrigerant inflow hole and a bulging outlet tank portion having a refrigerant outflow hole are arranged side by side, and a gap between the inlet tank portion and the outlet tank portion is provided. A plate-shaped tube element with a refrigerant passage formed inside that connects in a U-turn shape,
A laminated heat exchanger body in which a header constituting a refrigerant outlet or inlet is attached to a heat exchanger main body that is laminated so that the refrigerant inlet and outlet holes of adjacent tube elements are in communication with each other with fins interposed between them. In a type heat exchanger, two predetermined adjacent tube elements have adjacent sides formed in a flat shape without an inlet/outlet tank part, and an inlet side refrigerant circulation hole and an outlet side refrigerant circulation hole are formed in the header. , and the header is interposed between the two adjacent tube elements with the inlet side refrigerant flow hole aligned with the refrigerant inflow hole of the tube element and the outlet side refrigerant flow hole aligned with the refrigerant outlet hole of the tube element. 1. A stacked heat exchanger, which is attached to the header and further has a refrigerant inlet pipe connection hole or a refrigerant outlet pipe connection hole in communication with the inlet side refrigerant circulation hole or the outlet side circulation hole.
