International Classification:

F28D 1/047
F01D 25/12

Abstract:

A heat exchanger system is disclosed herein that extends between a first component and a second component. The heat exchanger system includes a hot flow path configured to convey hot fluid between the first component and the second component, a cool flow path configured to convey cool fluid, and a heat exchanger located between the first component and the second component along the hot flow path and the cool flow path. The heat exchanger includes at least one curve to accommodate the hot flow path and is configured to reduce the temperature of the hot fluid by allowing the transfer of thermal energy from the hot fluid to the cool fluid.

International Classification:

F28D 1/047
F28D 1/053

Abstract:

A heat exchanger includes a first fluid manifold extending along a first fluid axis from a first fluid inlet to a first fluid outlet. The first fluid manifold includes a first fluid inlet header, a first fluid outlet header, and a nested helical core section. The first fluid inlet header is disposed to fork the first fluid inlet into a plurality of first fluid branches distributed circumferentially and radially about the first fluid axis. The first fluid outlet header is disposed to combine the plurality of first fluid branches into the first fluid outlet. The nested helical core section fluidly connects the first fluid inlet header to the first fluid outlet header via a plurality of nested helical tubes, and includes radially inner and outer groups of circumferentially distributed helical tubes.

F28D 1/02

Abstract:

A heat exchanger includes a first fluid manifold extending along a first fluid axis from a first fluid inlet to a first fluid outlet. The first fluid manifold comprises a inlet header, a outlet header, and a multi-helical core section. The inlet header is disposed to fork the first fluid inlet into a plurality of first fluid branches distributed laterally across a plane normal to the first fluid axis. The outlet header is disposed to combine the plurality of first fluid branches into the first fluid outlet. The multi-helical core section fluidly connects the inlet header to the outlet header via a plurality of laterally distributed helical tubes, each helical tube corresponding to one of the plurality of first fluid branches and oriented parallel to all others of the plurality of helical tubes at each axial location along the first fluid axis.

International Classification:

F28F 9/02

Abstract:

A heat exchanger header for receiving a first fluid includes a tubular primary fluid channel oriented along a first axis and having a first cross-sectional area. A first branched region adjacent to the primary fluid channel fluidly connects to a plurality of tubular secondary fluid channels, each having a second cross-sectional area, and a second branched region adjacent to each of the secondary fluid channels fluidly connects to a plurality of tubular tertiary fluid channels, each having a third cross-sectional area.
