Abstract: 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.

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 first fluid inlet and outlet headers, and a helical core section. The inlet header is disposed to branch the first fluid inlet into a plurality of first fluid branches, and the outlet header is disposed to combine the plurality of first fluid branches into the first fluid outlet. The core section fluidly connects the inlet header to the outlet header via a plurality of helical tubes, such that each helical tube corresponds to one of the plurality of first fluid branches.

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.

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.
