  • Patent number: 11768037
    Abstract: A diffusion bonding heat exchanger includes a first heat transfer plate and a second heat transfer plate. A high-temperature flow path of the first heat transfer plate includes a connection channel portion configured such that a high-temperature fluid can flow across a plurality of channels within at least a range that overlaps a predetermined range in a stacking direction, the predetermined range being a range from a flow path inlet of the second heat transfer plate to a position downstream of the flow path inlet.
    Type: Grant
    Filed: March 25, 2019
    Date of Patent: September 26, 2023
    Assignee: Sumitomo Precision Products Co., Ltd.

  • Patent number: 9587892
    Abstract: This heat exchanger includes a core and a header tank. The entire peripheral edge of an opening of the header tank welded to the core has a bevel inclined from the internal surface of the header tank toward the external surface thereof at a predetermined bevel angle. At least a portion of the peripheral edge of the opening of the header tank has a second inclined portion inclined from the external surface of the header tank toward the internal surface thereof at an angle larger than the predetermined bevel angle.
