摘要： A stacked-type, multi-flow heat exchanger includes a first header pipe and a second header pipe formed opposite the first header pipe. The heat exchanger also includes a plurality of heat transfer tubes extending between the first header pipe and the second header pipe, such that the first header pipe and the second header pipe are in fluid communication via the heat transfer tubes. The heat exchanger further includes a plurality of fins alternately stacked with the plurality of heat transfer tubes. Moreover each of the ends of the first header pipe includes a first tapered portion having a reduced diameter relative to a diameter of a center portion of the first header pipe. In another embodiment, each of the ends of the second header pipe includes a second tapered portion having a reduced diameter relative to a diameter of a center portion of the second header pipe.
