PURPOSE:To eliminate the deformation of heat exchanging section or a groove and prevent leakage between respective fluids as well as between the outside of heat exchanger and respective fluids by a method wherein flat plates, having a groove and cutouts, are laminated and terminal plates, having groove and cutouts which are provided with the same configurations as the flat plates, are connected to the laminated flat plates. CONSTITUTION:Two kinds of flat plates 1a, 1b, having different configurations and provided with the groove for the flow paths of fluids and cutouts for entrance port or exit port of the fluids, are laminated alternately and the terminal plate 2a, having the same groove and cutouts as the flat plate 1a is connected to the flat plate 1a while the other terminal plate, having the same groove and cutouts as the flat plate 1b, is connected to the flat plate 1b. Accordingly, the connecting areas of the flat plate 1b becomes equal to the same area of the terminal plate 2a whereby the connecting strength of the terminal plate connected by brazing, diffusion welding or the like becomes equal to the connecting strength of lamination of respective flat plates and the leakage of fluid due to faulty connection may be prevented by the connecting surfaces. |
