    摘要： A heat exchanger plate (44A; 44B; 44B') provides heat transfer between a first flow (910) along a first flowpath (900) and a second flow (912) along a second flowpath (902). The heat exchanger plate has a substrate (52) having: a first face (62) and a second face (64) opposite the first face; a leading edge (54) along the second flowpath and a trailing edge along the second flowpath; a proximal portion having a plurality of inlet ports (46A, 46B, 46C) along the first flowpath and a plurality of outlet ports (48A, 48B, 48C) along the first flowpath; and a plurality of passageways (960A, 960B, 960C; 960A', 960B', 960C') along the first flowpath. Each passageway extends between a respective associated said inlet port and a respective associated said outlet port.

    摘要： A heat exchanger (10) includes a heat exchanger core (50). The heat exchanger core includes a plurality of tubes (52). Each tube of the plurality of tubes (52) includes a first end (54) and a second end (54) and extends from the first end (54) to the second end (56) in a lengthwise direction. Each tube of the plurality of tubes (52) is spaced from adjacent tubes in a height-wise direction and a widthwise direction. The plurality of tubes (52) is stacked to create a concave profile in the height-wise direction and widthwise direction. The concave profile extends in the lengthwise direction.
