HEAT EXCHANGER, ESPECIALLY CHARGE AIR COOLER FOR MOTOR VEHICLES

摘要

The invention relates to a heat exchanger, especially a charge air cooler ( 5 ) for motor vehicles. Said heat exchanger comprises a heat exchange block which is constituted of flat tubes ( 6 ) having flat tube ends and ribs ( 7 ) and tube bottoms ( 8 ) having ventilation passages ( 9 ) in which the flat tube ends are received and welded together. The heat exchanger also comprises collecting tanks that can be placed on the tube bottoms ( 8 ) and means for deflecting the flow in the feed section of the flat tube ends. The inventive heat exchanger is characterized in that the means for deflecting flow (deflection means 2 ) and means for reinforcing the flat tube ends (reinforcing means) are configured as an integrated structural component ( 1 ).
