Abstract:
An air-cooled charge air cooler for vehicles, comprising:an inlet collection tank on an opposite end of said charge cooler from an outlet collection tank; at least one row of tubes fluidly connected to the tanks to direct a charge air flow between the tanks; heat exchange elements arranged between the tubes to form a cooling grate through which a cooling airflow may be directed; and a pre-cooler in the inlet collection tank and extending over a cross-sectional area of the inlet collection tank so that a majority of the charge air flow must pass through the pre-cooler, the pre-cooler including flow paths to direct a coolant flow therethrough and channels between the flow paths for the charge air flow, the channels having a depth substantially perpendicular to the cross-sectional area in the range of about 25 mm to about 200 mm.
