A heat exchanger is provided and includes parting sheets flat along a first axis and curved along a second axis perpendicular to the first axis, a fin sheet interposed between the parting sheets and corrugated along the first axis to form fins that are curved along the second axis and diffusion bonds formed along an entire length of a fin to diffusion bond the entire length of the fin to the parting sheets.

A heat exchanger plate for provides heat transfer between a first flow along a first flowpath and a second flow along a second flowpath. The heat exchanger plate comprised a body having: a first face and a second face opposite the first face; a leading edge along the second flowpath and a trailing edge along the second flowpath; a proximal edge having at least one inlet port along the first flowpath and at least one outlet port along the first flowpath; and at least one passageway along the first flowpath. Along a proximal portion, the first face and the second face converge at a first angle. Along a distal portion, the first face and the second face converge at a second angle less than the first angle.

A heat exchanger includes a first flow circuit structure having at least a first portion defined by a plurality of conduits and a second flow circuit structure having at least a second portion disposed at the first portion such that walls of the second portion are disposed between the conduits and are free to move relative to the conduits. Fluid flowing through the first flow circuit structure is fluidically isolated from fluid flowing through the second flow circuit structure.

A turbofan gas turbine engine includes, in axial flow sequence, a heat exchanger module, a fan assembly, a compressor module, a turbine module, and an exhaust module. The fan assembly includes a plurality of fan blades defining a fan diameter (D). The heat exchanger module is in fluid communication with the fan assembly by an inlet duct, and the heat exchanger module includes a plurality of radially-extending hollow vanes arranged in a circumferential array with a channel extending axially between each pair of adjacent hollow vanes. An airflow entering the heat exchanger module is divided between a set of vane airflows through each of the hollow vanes and a set of channel airflows through each of the channels.

A counter-flow heat exchanger core includes a first wall defining a longitudinal axis. The first flow path is defined within the first wall. The first flow path includes a primary flow inlet and a primary flow outlet downstream from the primary flow inlet. The heat exchanger core includes at least two hollow vanes circumferentially spaced apart and extending in a radially inward direction from the first wall. Each of the at least two hollow vanes includes a first vane wall and a second vane wall. The heat exchanger core includes a second flow path defined within the at least two hollow vanes between the first vane wall and second vane wall of each of the at least two hollow vanes. The heat exchanger core includes at least one fin extending between two of the at least two circumferentially spaced apart vanes.

A heat transfer plate (10) for a plate-and-shell heat exchanger (100), the heat transfer plate (10) includes a plate body (11) having first and second sides (111, 112) opposite to each other in a direction perpendicular to the plate body (11); and a projection (12) protruding from the plate body (11) in a direction from the first side (111) towards the second side (112), extending along a segment (115S) of a periphery (115) of the plate body (11), and having a first end (121) and a second end (122).

The invention relates to an exchanger arrangement (3) for the heat transfer and/or selective material transfer between a first fluid (F1) and a second fluid (F2), which can flow through the arrangement (3), said arrangement (2) being constituted of a multitude (n) of adjacent local exchanger elements (E.sub.1, E.sub.2, . . . , E.sub.n). The exchanger arrangement (3) has at least in some sections a cylindrical shape or the shape of a segment thereof or a prismatic shape having a polygonal base or the shape of a segment thereof. The adjacent local exchanger elements (E.sub.1, E.sub.2, . . . , E.sub.n) are flat structures that are either wedge-shaped or sheet-like.

A plate for use in a heat exchanger is includes: a first surface; a second surface; first, second and third discrete flow passages passing through the plate from the first surface to the second surface, the second flow passage extending around the first flow passage and the third flow passage extending around the second flow passage. A plurality of fins extend parallel to the first surface across the third flow passage and have a first surface extending parallel to the first surface of the plate and a second surface extending parallel to and spaced from the first surface of the fin; and one or more pins protruding from the first surface of at least some of the fins. The pins extend away from the second surface of the fins.
