A cast part includes an outermost wall, at least one inner wall defining at least two internal passages and at least one cast cooling fin extending from an outer surface. The cast part including a cross-sectional circular area spanning at least a portion of each of four internal passages includes a ratio of interior empty space to inner wall space that improves heat transfer.

Cast plate heat exchanger and method of making using directional solidification

A cast part includes an outermost wall, at least one inner wall defining at least two internal passages and at least one cast cooling fin extending from an outer surface. The cooling fin includes a ratio of fin height to an average fin thickness that is greater than 2.0 and no more than 18.0. A method is also disclosed.

A heat exchanger assembly includes a plate including a plate portion having a leading edge, a trailing edge, an inlet side and an outlet side. The leading edge of the plate portion includes a terminal tip and a varying radius that decreases in a direction toward the terminal tip. An inlet manifold is on the inlet side. An outlet manifold is on the outlet side. A cast plate for a plate fin heat exchanger is also disclosed.

A combustor panel may include an attachment feature. Because conventional attachment features of conventional combustor panels may be insufficiently cooled, the present disclosure provides various combustor configurations for reducing hotspots in the vicinity of attachment features and/or for providing cooling airflow to and in the vicinity of attachment features.

A fairing assembly includes an outer wall, a first side wall, a second side wall, and a saddle. The first side wall and the second side wall extend from opposing sides of the outer wall. Together the first side wall, the second side wall, and the outer wall form a cavity within the fairing assembly. The saddle is positioned within the cavity and extends between the first side wall and the second side wall. The saddle has a first rib adapted to connect to the first side wall and a second rib adapted to connect to the second side wall. The first rib and the second rib connect together at a central hub.
