The heat exchanger has: an inner wall (250) in heat transfer relation with the gaspath (90); an outer wall (252); tubes between the inner wall (250) and the outer wall (252) bounding respective segments of the fuel flowpath; and a heat transfer fluid (140) between the inner wall (250) and the outer wall (252) and in heat transfer relation with the tubes and the inner wall (250).",
