Abstract: A heat exchanger includes an inner fin arranged in a refrigerant passage. The inner fin has side wall portions formed so as to extend in a predetermined direction and arranged parallel to each other. A gap formed between the side wall portions facing each other is a passage portion through which refrigerant flows. Each of the side wall portions has a plurality of openings arranged in the predetermined direction. An inclined surface inclined with respect to the predetermined direction is formed in a part of the side wall portion located between the openings adjacent to each other.

Abstract: A core part includes plural plates stacked with a gap therebetween so as to form plural refrigerant passages and plural cooling water passages. The refrigerant passages are communicated with each other in a stacking direction of the plates by a refrigerant inlet tank section and a refrigerant outlet tank section distanced from each other. A refrigerant inlet and a refrigerant outlet communicate with the refrigerant inlet tank section and the refrigerant outlet tank section, respectively, and are provided at one end of the core part in the stacking direction. The refrigerant inlet and the refrigerant inlet tank section are communicated with each other by a refrigerant inlet passage. A distance between a center of the refrigerant outlet tank section and a center of the refrigerant outlet is shorter than a distance between a center of the refrigerant inlet tank section and a center of the refrigerant inlet.

Abstract: A condensing portion is formed such that a first refrigerant flow path through which a gas-phase refrigerant flowing into a refrigerant inlet flows and a first heat-medium flow path through which a heat medium flows overlap each other in a stacking direction of plates. A gas-liquid separator separates the refrigerant into gas-phase refrigerant and liquid-phase refrigerant and discharges the liquid-phase refrigerant. A subcooling portion is disposed on one side in the stacking direction with respect to the condensing portion, is formed such that a second refrigerant flow path through which the liquid-phase refrigerant discharged from the gas-liquid separator flows toward a refrigerant outlet and a second heat-medium flow path through which the heat medium flows overlap each other in the stacking direction.

Abstract: A stack type heat exchanger includes a plurality of first plates and a plurality of second plates. At least one of the respective first plates and the respective second plates has a protrusion protruding from a main body of the first plate or the second plate toward a first flow path, the protrusion being located at a peripheral portion of a tank space in the first flow path. The first plate and the second plate are joined to each other through the protrusion. The protrusion has a top portion and a side wall portion. A part of the side wall portion adjacent to the tank space has a thick structure portion, an entire thickness of the thick structure portion being thick in a direction perpendicular to the stacking direction.
