AIRCRAFT HEAT EXCHANGERS AND PLATES

A heat exchanger plate 44 for 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 44 comprised a body 52 having: a first face 62 and a second face 64 opposite the first face 62; a leading edge 54 along the second flowpath 902 and a trailing edge 56 along the second flowpath 902; a proximal edge 60 having at least one inlet port 22 along the first flowpath 900 and at least one outlet port 24 along the first flowpath 900; and at least one passageway along the first flowpath 900. Along a proximal portion 302, the first face 62 and the second face 64 converge at a first angle. Along a distal portion 304, the first face 62 and the second face 64 converge at a second angle less than the first angle.
