Claim 0:
1. An apparatus for a gas turbine engine, comprising:
a vane array including an inner platform, an outer platform and a plurality of vanes, the inner platform extending circumferentially about a centerline and forming an inner peripheral boundary of a flowpath through the vane array, the outer platform extending circumferentially about the centerline and forming an outer peripheral boundary of the flowpath through the vane array, and the plurality of vanes extending across the flowpath between the inner platform and the outer platform; and
a heat exchanger integrated with the vane array having a first inlet and a second inlet located on the outer platform, the heat exchanger comprising a passage following a tortuous trajectory along a first wall of the vane array, the passage extending between the first inlet and the second inlet, the passage including a first passage segment, a second passage segment and a third passage segment sequentially arranged along the tortuous trajectory, the second passage segment axially overlapping the first passage segment and the third passage segment as the second passage segment follows the tortuous trajectory, and the second passage segment circumferentially between the first passage segment and the third passage segment.
