An apparatus for cooling the charging air of a supercharged internal combustion engine wherein a part of the charging air delivered by the charger is branched off and is accelerated to supersonic velocity in a Laval nozzle. With the accelerated air, surrounding air is sucked in according to the principle of a jet pump. The mixture which forms flows through the heat exchanger, in which it takes up heat from the charging air flowing around the tubes, and thereafter is discharged to the surroundings. |
