Patent ID: 8381804

Claim:
A heat exchanger comprising: a heat exchanger core; and at least one manifold in fluid flow communication with said heat exchanger core for receiving a first fluid to be cooled by a second fluid; the manifold including a plurality of vanes defining a corresponding plurality of first flow channels and second flow channels through which said first fluid and said second fluid each flow, where each of said first and second flow channels has a changing aspect ratio along its length, and each said first flow channel has an input end and an output end; and wherein each said input end includes a ramped portion for deflecting and turning a portion of said first fluid entering each of said first flow channels, and wherein each of said vanes further includes one of a spiral configuration that operates to turn said first fluid in a spiral configuration as said first fluid flows along said first flow channel; wherein said second fluid flows in a direction within said at least one manifold that is generally parallel to a flow of said first fluid; and wherein said first and second flow channels are arranged in alternating fashion within the manifold.
