Abstract:
1. A liquid cooled charge air cooler for use with an internal combustion engine comprising: a plurality of separator plates supported in parallel spaced relation with one another to define a plurality of pairs of adjacent separator plates, the pairs alternatingly defining a first set of adjacent pairs and a second set of adjacent pairs; a charge air inlet and a charge air outlet each in fluid communication with the first set of adjacent pairs; a coolant inlet and a coolant outlet each in fluid communication with the second set of adjacent pairs, fins extending between adjacent separator plates of the first set of adjacent pairs to define a charge air flow path between the charge air inlet and the charge air outlet; and a plurality of dams extending between adjacent separator plates of the second set of adjacent pairs in a select offset configuration to define a multi-pass coolant flow path between the coolant inlet and the coolant outlet in heat exchange relation with the charge air flow path, wherein the multi-pass coolant flow path includes at least two substantially oppositely directed portions, each dam comprising an associated bypass port allowing a portion of coolant to bypass at least a portion of the coolant flow path through the dams.
