  • Patent number: 4969421
    Abstract: The present invention comprises a cooling device for an internal combustion engine disposed in an engine compartment of a motor vehicle. A radiator is positioned in front of the internal combustion engine. An axial-radial blower serving to feed cooling air through the radiator into the engine compartment is mounted between the radiator and the internal combustion engine. An air collection housing with an air outlet directed into the upper area of the engine compartment is connected to the axial-radial blower. The air collection housing and outlet collect and direct the cooling air fed by the axial-radial blower for the purpose of cooling the engine block, especially parts of the internal combustion engine that are thermally intensely stressed.
