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 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.
