  • Patent number: 4436145
    Abstract: A charge air cooler is provided for mounting within the intake manifold of a combustion engine. The charge air cooler comprises a heat exchanger core formed by a plurality of relatively lightweight heat transfer elements defining a first flow path for charge air prior to ingestion of the charge air by the engine and a second flow path for a coolant in heat transfer relation with the charge air. The heat exchanger core supports at least one transversely extending rigid mounting sleeve for receiving a mounting bolt passed through a bolt-receiving hole in the intake manifold to secure the charge air cooler within the intake manifold.
