Abstract: A heat exchanger is formed by stacking plates with each other. The heat exchanger includes a refrigerant receiving tank configured to receive a refrigerant, a refrigerant discharging tank configured to discharge the refrigerant that has heat-exchanged, and refrigerant passages in which heat exchange between the refrigerant and another fluid is performed. The refrigerant passages fluidly connect between the refrigerant receiving tank and the refrigerant discharging tank. The refrigerant receiving tank includes a swirl structure configured to generate a swirling component in a flow of the refrigerant in the refrigerant receiving tank.

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 stacked heat exchanger includes: passage tubes stacked with each other to support a heat exchange object, a passage being defined in the passage tube for a heat medium to exchange heat with the heat exchange object; and a pipe connected to one of the passage tubes located at one end in a stacking direction of the plurality of passage tubes. Each of the passage tubes has a protruding pipe portion protruding in the stacking direction and communicating with the adjacent passage tube in the stacking direction. The one of the passage tubes located at the one end in the stacking direction is an in/out passage tube. The pipe has a surface at one end in a longitudinal direction of the pipe, and the surface intersects the longitudinal direction of the pipe and is joined to the in/out passage tube.

Abstract: A heat exchanger includes a fin arranged in a first passage and a tubular tank portion formed so as to penetrate plate members stacked in a stacking direction. An inflow port is formed in a peripheral wall of the tank portion to allow a refrigerant to flow into the first passage. When the fin is arranged in a fin installation portion in the first passage, a passage reduction portion is formed at the inflow port and is narrower than a width of the fin installation portion in the stacking direction.

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.
