Kind Code:
B2
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).
