1. A heat exchanger comprising:
a front end and an aft end spaced apart from each other;
heat exchanger cores that are circumferentially spaced apart from each other in an annular loop such that they define circumferential gaps between adjacent pairs of the cores;
wherein the cores, configured individually or as axially aligned sets, extend from the front end to the aft end and have circumferentially facing inlet sides and circumferentially facing outlet sides configured such that the inlet sides and the outlet sides from the adjacent pairs of the cores face into the same ones of the circumferential gaps; and
core guide vanes disposed in the circumferential gaps;
the core guide vanes have an aft portion that extends from the front end to the aft end of the heat exchanger;
wherein: at the front end the heat exchanger, the core guide vanes are closer to the outlet side of the cores; and at the aft end the heat exchanger, the core guide vanes are closer to the inlet sides of the cores;
whereby the core guide vanes are configured to turn a gas flow from an axial direction toward the inlet sides of the cores and from the outlet sides of the cores toward the axial direction.
