PROBLEM TO BE SOLVED: To provide a radiator capable of reducing generation of distortion caused by thermal influence and of being made thin. SOLUTION: This radiator 1 is a device in which cooling water for cooling an engine 2 flows inside of a core portion 16, and the cooling water is cooled by heat exchange between the ventilated air and the cooling water. The core portion 16 is provided with an inflow-side tube 17 for allowing the cooling water flowing in from a tank 21 positioned at one side of the radiator 1, to flow toward a tank 22 positioned at the other side, and an outflow-side tube 18 disposed in parallel with the inflow-side tube 17 in the ventilating direction A of the air so that the cooling water passing through the inflow-side tube 17 turns in the tank 22 and flows while forming opposed flow. Further the inflow-side tube 17 and the outflow-side tube 18 are disposed adjacent to each other in the ventilating direction A through a partitioning portion. COPYRIGHT: (C)2007,JPO&INPIT
