Abstract
A curved cross-flow heat exchanger including a first flow path for a first fluid stream which is arranged substantially at right angles to a second flow path for a second fluid stream, wherein: the first flow path is confined within one or more heat exchanger sections that bridge between opposite sides of the heat exchanger, the one or more heat exchanger sections having a leading edge positioned in the second flow path, wherein each of the one or more heat exchanger sections is a curved laminated heat exchanger section and comprises a leading edge that is curved in a direction normal to the second flow path.

A curved cross-flow heat exchanger comprising a first flow path for a first fluid stream which is arranged substantially at right angles to a second flow path for a second fluid stream, wherein:
- the first flow path is confined within one or more heat exchanger sections that bridge between opposite sides of the heat exchanger, the one or more heat exchanger sections having a leading edge positioned in the second flow path,
- wherein each of the one or more heat exchanger sections is a curved laminated heat exchanger section and comprises a leading edge that is curved in a direction normal to the second flow path,
- wherein each of the one or more heat exchanger sections comprises a plurality of laminate members that are stacked one on top of another and follow a curved profile, each comprising a leading edge portion such that the leading edge portions of the stacked laminate members form the leading edge of the curved laminated heat exchanger section, and wherein the stacked laminate members form two or more channels of the first flow path, and each channel comprises at least a pair of laminate members with opposed hollowed regions.
A method of manufacturing a curved cross-flow heat exchanger comprising a first flow path for a first fluid stream which is arranged substantially at right angles to a second flow path for a second fluid stream, the method comprising:
- producing a plurality of laminate members;
- assembling the plurality of laminate members into a stack to form a curved laminated heat exchanger section for the first fluid stream;
- arranging the curved laminated heat exchanger section between opposite sides of the cross-flow heat exchanger to provide an assembly in which the curved laminated heat exchanger section comprises a leading edge curved in a direction normal to the second flow path;
- and
- brazing the components to one another,
- wherein each laminate member comprises a leading edge portion such that the leading edge portions of the stacked laminate members form the leading edge of the curved laminated heat exchanger section, and wherein the stacked laminate members form two or more channels of the first flow path, and each channel comprises at least a pair of laminate members with opposed hollowed regions.
