  • Patent number: 10147668
    Abstract: A stacked cooler includes flow pipes that are stacked, each of the flow pipes having a flat shape and including a medium passage in which a heat medium flows, a heat exchange object that is disposed between each adjacent two of the flow pipes and is clamped between their flat planes, a protruding pipe part that is connected to at least one of the flow pipes and protrudes in a stacking direction of the flow pipes, and a load restraining part that restrains a load applied to a connection portion of the at least one of the flow pipes to the protruding pipe part as compared with a load applied to the other portion of the at least one of the flow pipes.
    Type: Grant

  • Patent number: 10107553
    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.
