PROBLEM TO BE SOLVED: To provide a new oil cooler capable of stably placing a base plate 15 and an end plate of a core portion 11 at a regular position before brazing, and miniaturizing the base plate and reducing the weight. SOLUTION: The base plate 15 thicker than the core plate 12 is fixed to the end plate 12A defining a bottom surface of the core portion 11 provided with oil flow channels 13 and cooling water flow channels 14 alternately formed among a plurality of stacked core plates 12. The core plate 12 and the base plate 15 are integrally brazed. A plurality of projecting portions 30 projecting to a core portion 11 side are formed on the base plate 15. Each projecting portion 30 is brazed to the core plate 12C of second lowest position through a fitting hole 31 penetrating through the end plate 12A. COPYRIGHT: (C)2008,JPO&INPIT
