Abstract:
1. A heat exchanger system comprising a duct that is substantially cylindrical along a length thereof and having a duct wall with a duct wall outer surface and a duct wall inner surface; a heat exchanger partial shell joined to the duct wall inner surface, so that the heat exchanger partial shell and a shell portion of the duct wall inner surface constitute a heat exchanger; a heat exchanger inlet manifold at an inlet location along the duct wall and comprising an elongated nonplanar inlet sheet of material defining a portion of the inlet manifold, wherein the inlet sheet of material is joined to the duct wall outer surface, so that the elongated nonplanar inlet sheet and an inlet-manifold portion of the duct wall outer surface define the inlet manifold; a heat exchanger inlet opening extending through the duct wall between the inlet manifold and the heat exchanger; a heat exchanger outlet manifold at an outlet location along the duct wall and comprising an elongated nonplanar outlet sheet of material defining a portion of the outlet manifold, wherein the outlet sheet of material is joined to the duct wall outer surface, so that the elongated nonplanar outlet sheet and an outlet-manifold portion of the duct wall outer surface define the outlet manifold; and a heat exchanger outlet opening extending through the duct wall between the outlet manifold and the heat exchanger, wherein the heat exchanger is positioned to extend circumferentially with respect to the duct.
