A HEAT EXCHANGER FOR A VEHICLE

摘要

A heat exchanger comprising a core portion 110 which includes a plurality of tubes 111 through which fluid flows and fins 112 joined to the external surface of the tubes. Reinforcement plates 130 are disposed at end portions of the core and are in parallel with the tubes. Disposed at the other end portions of the core and arranged perpendicular to the tubes is a header tank 120 and a core plate 121. The core plates to which the tubes are joined and the header tank being welded to the core plate so that the tank is in fluid communication with the tubes. Extension portions (123, fig.4b) are provided at longitudinal end potions of the core plate and have a width 'Wc' the same as the width 'Wi' of the reinforcement plate. The extensions (123) extend onto longitudinal end portions of the reinforcement plate so that they can be brazed thereto. Holding portions 131 are also provided at the longitudinal end portions of the reinforcement plate to hold therein the extensions. Preferably the holding portions are formed by cutting the longitudinal end portions of the reinforcement plate so that can be deformed so they extend in a longitudinal direction. Preferably the heat exchanger is an intercooler for a vehicle with air acting as the fluid medium.
