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.

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: In a thermal management system, a low-temperature side heat medium circuit includes a first circuit, a second circuit, a coupling part, and a flow rate adjustment part. The first circuit includes a first heat exchange unit, and is configured such that a heat medium can circulate via a chiller and the first heat exchange unit. The second circuit includes a second heat exchange unit, and is configured such that the heat medium can circulate via the second heat exchange unit and a heat medium pump. A controller controls an operation of the flow rate adjustment part and adjusts the flow rate of the heat medium in the coupling part, so as to make a temperature zone of the heat medium flowing through the first circuit and a temperature zone of the heat medium flowing through the second circuit have respective determined values.
