  • Patent number: 7426955
    Abstract: A core structure of a heat exchanger includes seat plates arranged opposite to each other with a predetermined space interposed between them and formed with tube holes, reinforcements connecting the seat plates at their end portions, tubes fixed at its both end portions by insertion into the tube holes, corrugated fins arranged between the tubes, and an upper and lower tanks attached to the seat plates. The tanks are connected by the tubes so that coolant flows between the tanks through the tubes. Tubes arranged at outermost positions of a core part among the tubes are inserted at its end portions by insert members so that the insert members can increase rigidity of the end positions of the outermost positioned tubes and ensure flowing of the coolant between the tanks through the outermost positioned tubes.

  • Patent number: 6988541
    Abstract: An oil cooler is held by holding plates. Top portions of side pieces of each holding plate are disposed through a side wall of a tank and are bent at the outer surface of the tank, so that circular interposed members and the oil cooler are retained by being sandwiched between middle supporter pieces of the holding plates and the side wall of the tank in the stacking direction of element units such that the oil cooler is movable in the longitudinal direction with respect to the side wall of the tank. By inserting connecting pipes of the oil cooler through openings of the tank so as to temporarily assemble the connecting pipes into openings of a tube plate, blocking flanges of the connecting pipes are retained while being in contact with the outer surface of the side wall of the tank.
