  • Publication number: 20220176659
    Abstract: A fitting method is for fitting a material to be repaired and a repair patch to be adhesively bonded to the material at adhesive surfaces, each adhesive surface having at least two or more of curved portions. The fitting method includes measuring a shape of the material; measuring a shape of the repair patch; dividing repair patch shape measurement data acquired at measuring the shape of repair patch into pieces of divided data each including one or less of the curved portions; performing, at the adhesive surfaces, fitting processing of the pieces of divided data acquired at dividing the repair patch shape measurement data to material-to-be-repaired shape measurement data acquired at measuring the shape of material; and calculating a gap amount between the material-to-be-repaired shape measurement data and repair patch shape fitting data acquired from the fitting processing at the adhesive surfaces.

  • Patent number: 10207376
    Abstract: An oil cooler has a core portion (1) formed of stacked core plates (5), a bottom plate (2), a second bottom plate (3) and a top plate (4), and these are brazed in a furnace. The core plate (5) has oil communication ports (13), cooling water communication ports (14) and an oil outlet port (15). The lower end core plate (5) has a boss portion (16) surrounding the cooling water communication port (14) and a boss portion (17) surrounding the oil outlet port (15). Opening portions (32, 33) opposite to the boss portions (16, 17) are formed through the bottom plate (2). Therefore, at the time of the brazing, a melted brazing material is not excessively gathered in the boss portion (16, 17) because the melted brazing material is absorbed in the opening portions (32, 33).
