Abstract:
A heat exchanger, particularly a charge-air cooler, in which heated air is cooled by a cooling fluid, is constructed from stacked pairs of plates with air flow passages arranged between adjacent ones of the plate pairs. Each of the pairs of plates includes an inlet and an outlet for the cooling fluid flow arranged within an inlet and outlet region and aligned with the direction of the air flow through the heat exchanger. A flow barrier formed by beads of the plates is arranged between the inlet and outlet region and a heat exchange section of the plate pair. A flow of cooling fluid is directed through a coolant flow path extending through the plate pair between the cooling fluid inlet and the cooling fluid outlet, with the cooling fluid flow path having a first portion along one longitudinal edge of the plates, a second portion along an opposing longitudinal edge of the plates, and a third portion extending through the heat exchange section between the first and second portions. The flow of cooling fluid through the third portion is in a direction counter to the flow of air.

Claim (Index 1):
A heat exchanger comprising:\n a plurality of stacked plate pairs having air flow passages arranged between adjacent ones of the plurality of stacked plate pairs, the air flow passages extending between a set of first longitudinal edges of the stacked plate pairs and an opposing set of second longitudinal edges of the stacked plate pairs to define an air flow direction through the heat exchanger perpendicular to the first and second longitudinal edges; an inlet and outlet region for cooling fluid, each of the plurality of stacked plate pairs having an inlet for cooling fluid and an outlet for cooling fluid arranged within the inlet and outlet region and aligned with the air flow direction; a plurality of corrugated internal fins, each being located within one of the plurality of stacked plate pairs and having a low pressure drop direction aligned with the direction of the longitudinal edges and a high pressure drop direction aligned with the air flow direction; a plurality of flow barriers constructed by beads of the plate pairs, said plurality of flow barriers arranged between the inlet and outlet region for the cooling fluid and the plurality of corrugated internal fins; and a plurality of cooling fluid flow paths, each of the cooling fluid flow paths extending through one of the plurality of stacked plate pairs between the inlet for cooling fluid and the outlet for cooling fluid and including a first portion extending between one of the plurality of corrugated internal fins and one of the set of first longitudinal edges, a second portion extending between that one of the plurality of corrugated internal fins and one of the set of second longitudinal edges, and a third portion extending through that one of the plurality of corrugated internal fins in the high pressure drop direction to provide fluid communication between the first portion and the second portion, wherein the direction of cooling fluid flow along the third portion is counter to the air flow direction.
