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 11):
A method of cooling a flow of heated air, comprising:\n directing a flow of heated air through air flow passages of a heat exchanger in an air flow direction; directing a flow of cooling fluid into the heat exchanger and distributing the flow of cooling fluid among plate pairs of the heat exchanger through cooling fluid inlets of the plate pairs, the air flow passages being arranged between adjacent ones of the plate pairs; within each one of the plate pairs, directing the cooling fluid through a first duct in a direction perpendicular to the air flow direction; within each one of the plate pairs, directing a first portion of the cooling fluid from the first duct through a heat exchange section of the plate pair in a direction counter to the air flow direction; transferring heat from the flow of heated air to the first portion of the cooling fluid as the first portion of the cooling fluid flows through the heat exchange section of the plate pair; within each of the plate pairs, directing a second portion of the cooling fluid from the first duct through a bypass section of the plate pair in a direction counter to the air flow direction, the transfer of heat between the flow of heated air and the second portion of the cooling fluid being inhibited within the bypass section so that the second portion of the cooling fluid exits the bypass section at a lower temperature than the first portion of the cooling fluid exits the heat exchange section; within each of the plate pairs, directing the first portion of the cooling fluid through a second duct in a direction perpendicular to the air flow direction after directing the first portion of the cooling fluid through the heat exchange section of the plate pair; within each of the plate pairs, directing the second portion of the cooling fluid through the second duct in a direction perpendicular to the air flow direction after directing the second portion of the cooling fluid through the bypass section of the plate pair; and removing the flow of cooling fluid from the heat exchanger through cooling fluid outlets of the plate pairs.
