Abstract:
1. A heat exchanger tube, comprising: at least one flow path extending along a length of the heat exchanger tube from a first end to a second end opposite of the first end; a fluid flow section in which the at least one flow path is enclosed within the heat exchanger tube and surrounded by a top wall of the heat exchanger tube, a bottom wall of the heat exchanger tube, and a pair of partitions extending between the top wall and the bottom wall; an inlet section in which the bottom wall of the heat exchanger tube and the pair of partitions abut the at least one flow path, wherein the top wall does not extend along the at least one flow path in the inlet section to allow fluid to flow into the at least one flow path, and wherein the inlet sections is spaced from the first end and the second end; and a second flow path extending along the length of the heat exchanger tube from the first end to the second end, wherein a portion of the top wall is removed within the inlet sections to expose the second flow path to allow the fluid to flow into the second flow path, and the top wall is not removed for one or more flow paths disposed between the at least one flow path and the second flow path.
