Abstract: A stacked heat exchanger including a core portion having a plurality of plates stacked on each other to define a flat refrigerant passage and a flat heat medium passage. A first connection member that provides an inlet and an outlet for allowing the refrigerant to flow into the refrigerant passage. A second connection member that provides an inlet and an outlet for allowing the heat medium to flow into the heat medium passage, in which the inlet and the outlet are configured in a state where the heat medium flowing into the heat medium passage flows in an opposite direction to that of the refrigerant flowing in the refrigerant passage. The core portion includes an offset fin disposed in at least the refrigerant passage.

Abstract: A stacked heat exchanger includes a first heat-exchanging portion in which heat is exchanged between a refrigerant and a coolant. The first heat-exchanging portion has multiple first plate members stacked and bonded to one another, and multiple first refrigerant channels and multiple coolant channels provided among the multiple first plate members. The multiple first refrigerant channels and the multiple coolant channels are arranged in a staking direction of the multiple first plate members. The stacked heat exchanger further includes a second ceiling board bonded to a first ceiling board which is one of the multiple first plate members located on an outermost side in the stacking direction, and a vapor-liquid separation portion having a space between the first ceiling board and the second ceiling board, separating the refrigerant flowed in into a vapor and a liquid, and storing an excess refrigerant in a refrigeration cycle.
