Patent ID: 7757753

Claim:
A heat exchanger comprising: a first manifold; a second manifold; a first multichannel tube in fluid communication with the first manifold and the second manifold and including a plurality of generally parallel flow paths extending therethrough having a first configuration; a second multichannel tube in fluid communication with the first manifold and the second manifold and including a plurality of generally parallel flow paths extending therethrough having a second configuration different from the first configuration; and a pair of baffles in the first manifold to isolate at least one multichannel tube between the baffles of the pair, wherein the pair of baffles is disposed between the first multichannel tube and the second multichannel tube, and wherein the at least one multichannel tube is isolated within the first manifold only; wherein the second manifold is configured to direct a fluid exiting the first multichannel tube directly into both the at least one isolated multichannel tube and the second multichannel tube.
