Charge air cooler mounting arrangement

A charge air cooler mounting arrangement, comprising:

• a plate-fin charge air cooler including a heat exchanger core having a stacked plurality of generally parallel plate-fin heat transfer elements defining first and second generally parallel flow paths for respective passage in heat transfer relation of charge air and a coolant;
• a plurality of relatively rigid mounting sleeves carried by said heat exchanger core each to extend generally perpendicularly of said plate-fin elements and having a length to project at least slightly from the opposite sides of said heat exchanger core;
• an intake manifold having a chamber formed therein for reception of said heat exchanger core with said mounting sleeves extending transversely between a pair of manifold side walls bounding opposite sides of the chamber;
• means extending through said side walls and into each of said mounting sleeves for securing said heat exchanger core within said manifold and for bringing said side walls into bearing engagement with the opposite ends of said mounting sleeves;
• and
• means coupled between said plate-fin elements and each of said mounting sleeves for preventing leakage between said first and second flow paths in the vicinity of said mounting sleeves.

A charge air cooler mounting arrangement, comprising:

• a charge air cooler including a plate-fin heat exchanger core defined by an alternating stack of first plate-fin elements and second plate-fin elements and a plurality of divider plates each disposed between an adjacent pair of said first and second plate-fin elements, said first plate-fin elements and said divider plates cooperating to form a first flow path for charge air, and said second plate-fin elements and said divider plates cooperating to form a second flow path for a coolant in heat transfer relation with the charge air;
• at least one relatively rigid mounting sleeve carried by said heat exchanger core to extend transversely therethrough and having a length at least as great as the width of said core;
• a plurality of annular sealing rings carried about said mounting sleeve and each projecting radially therefrom between a pair of said divider plates, said rings each being sealingly connected to said sleeve and said associated pair of divider plates to prevent leakage of fluid between said first and second flow paths;
• an intake manifold having a chamber formed therein for reception of said heat exchanger core with said mounting sleeve extending transversely between a pair of manifold side walls bounding opposite sides of the chamber;
• and
• means extending through said side walls and into said mounting sleeve for securing said heat exchanger core within said manifold and for bringing said side walls into bearing engagement with the opposite ends of said mounting sleeve.

A charge air cooler for mounting within an engine intake manifold, comprising:

• a plate-fin heat exchanger core having an alternating stacked plurality of generally parallel first and second plate-fin elements and a plurality of generally parallel divider plates each disposed between an adjacent pair of said first and second plate-fin elements, said first plate-fin elements cooperating with said divider plates to define a first flow path and said second plate-fin elements cooperating with said divider plates to define a second flow path generally parallel with said first flow path, said first flow path and second flow path being for respective passage in heat transfer relation of charge air and a coolant;
• at least one relatively rigid mounting sleeve carried by said heat exchanger core to extend transversely thereof and having a length at least as great as the width of said heat exchanger core;
• and
• a plurality of annular sealing rings carried about said sleeve in axially spaced positions each between a respective pair of said divider plates in a plane corresponding with a respective one of said second plate-fin elements, said sealing rings being secured to said sleeve and said divider plates to prevent leakage between said first and second flow paths.
