Abstract:
1. A heat exchanger comprising: a first manifold; a second manifold; a plurality of multichannel tubes extending lengthwise between and in fluid communication with the first and second manifolds, the plurality of multichannel tubes being configured to receive an external fluid flowing across the width of each multichannel tube from a leading edge to a trailing edge and configured to flow an internal fluid along the length of each multichannel tube such that the internal fluid exchanges heat with the external fluid and a vapor quality of the internal fluid changes as it progresses along the length; a plurality of generally parallel flow paths disposed within each multichannel tube and extending lengthwise through each multichannel tube; and a flow control mechanism included within at least one multichannel tube, the flow control mechanism being configured to allow more of the internal fluid to flow near the leading edge than near the trailing edge of the at least one multichannel tube, wherein the flow control mechanism includes a crimped flow path disposed near the trailing edge and an uncrimped flow path disposed near the leading edge.
