Abstract
A heat exchanger includes a heat exchanger body having a first end and a second end opposed to the first end along a flow axis. A plurality of flow channels is defined in the heat exchanger body extending axially with respect to the flow axis. A first set of the flow channels forms a first flow circuit and a second set of the flow channels forms a second flow circuit that is in fluid isolation from the first flow circuit. Each flow channel is fluidly isolated from the other flow channels. The flow channels all conform to a curvilinear profile.
Claims9
A heat exchanger comprising:
- a heat exchanger body having a first end and a second end opposed to the first end along a flow axis;
- a plurality of flow channels defined in the heat exchanger body extending axially with respect to the flow axis, wherein a first set of the flow channels forms a first flow circuit, wherein a second set of the flow channels forms a second flow circuit that is in fluid isolation from the first flow circuit,
- wherein each flow channel is fluidly isolated from the other flow channels, wherein each flow channel of the first flow circuit includes a respective inlet on the first end of the heat exchanger body and a respective outlet on the second end of the heat exchanger body, and wherein each flow channel of the second flow circuit includes a respective inlet on one of the first and second ends of the heat exchanger body and a respective outlet on the other of the first and second ends of the heat exchanger body, and
- wherein the flow channels all conform to a curvilinear profile, wherein the curvilinear profile includes a sinusoidal wave pattern extending axially relative to the flow axis, wherein the curvilinear profile is a common curvilinear profile for the flow channels and includes the sinusoidal wave pattern with waves of a first amplitude and wavelength configuration extending in a first direction normal to the flow axis, and waves of a second amplitude and wavelength configuration extending in a second direction normal to the flow axis, wherein the first direction and second direction are different from one another, and wherein the first wavelength and the second wavelength are different from one another.
