    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 plurality of components of a refrigeration cycle are connected to a connection module. The connection module includes a body having a refrigerant flow path that constitutes a part of a refrigerant flow path in the refrigeration cycle. The refrigerant flow path includes a high-temperature-side flow path and a low-temperature-side flow path. The high-temperature-side flow path has a connection port to which a high-temperature-side component of the plurality of components, through which a high-pressure refrigerant of the refrigeration cycle flows, is connectable. The low-temperature-side flow path has a connection port to which a low-temperature-side component of the plurality of components, through which a refrigerant having a lower temperature than the high-pressure refrigerant flows, is connectable.

    Abstract: A heat exchanger has a tube and an inner fin. A heat medium exchanging heat with a heat exchange target flows in the tube, and the tube has a flat shape in cross section perpendicular to a flow direction of the heat medium. The inner fin has first fins and second fins. The second fins are formed parallel to the flow direction in at least one of an upstream end portion located on an upstream side of an area, in which the first fins are formed, in the flow direction or a downstream end portion located on a downstream side of the area in the flow direction. Fin pitches between the first fins are all identical with each other. At least one of fin pitches between the second fins is different from other fin pitches between the second fins.

    Abstract: A heat exchanger includes a flow passage pipe that has a flat shape having a predetermined thickness, a heat medium flowing in the flow passage pipe, the heat medium exchanging heat with a heat exchange target, and an inner fin located inside the flow passage pipe. The inner fin includes a wavy fin that partitions a main passage into multiple partitioned passages, and a guide wall connected to the wavy fin. An x-direction is a lengthwise direction of the flow passage pipe, a z-direction is a thickness direction of the flow passage pipe, and a y-direction is a direction perpendicular to both the x-direction and the z-direction. The wavy fin includes a first convex portion convex to a first side in the y-direction, and a second convex portion convex to a second side in the y-direction. The wavy fin has an opening portion through which two partitioned passages adjacent to each other communicate with each other. The guide wall protrudes from the wavy fin into the partitioned passage. The heat exchanger is capable of enhancing a heat transfer and improving a thermal performance of the heat exchanger.

    Abstract: A cooling module has a heat generating body, a heat exchanger made of metal, and an insulating plate. The heat generating body has a heat dissipating surface. The heat exchanger has cooling surface facing the heat dissipating surface. The insulating plate has a first surface and a second surface. The insulating plate is interposed between the heat dissipating surface and the cooling surface on a condition that the insulating plate faces the heat dissipating surface and that the second surface faces the cooling surface. The insulating plate and the cooling surface are joined to be one body by a joining material. The heat dissipating surface and the insulating plate are in close contact with each other through an elastic member. The heat dissipating surface and the cooling surface are thermally connected to each other through the joining material, the insulating plate, and the elastic member.

    Abstract: A cooler includes a cooling pipe having a cooling surface in contact with a heat-exchanged component, and a refrigerant passage. A pair of outer passages are formed between a pair of opposed inner wall surfaces which are located at both ends of an inner wall surface of the cooling pipe in a perpendicular direction and which constitute the refrigerant passage, and a pair of partition walls that are located at both ends of an inner fin in the perpendicular direction. At least one flow-regulating rib is formed in the refrigerant passage to project into the refrigerant passage at a position inward of the pair of outer passages in the perpendicular direction and at a position outward of an inflow hole and a discharge hole in the perpendicular direction as well as at a position outward of the inner fin in an arrangement direction and at a position inward of the inflow hole and the discharge hole in the arrangement direction. The flow-regulating rib is configured to restrict flow rates of refrigerant through the pair of outer passages.

    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.
