Abstract
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.
Claims20
A heat exchanger, comprising:
- 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 conformal heat exchanger for disposition within a curved passage and comprising multiple layers each comprising:
- first and second parting sheets, each flat along a first axis and curved along a second axis perpendicular to the first axis to conform to the curved passage;
- a fin sheet interposed between the first and second parting sheets and corrugated along the first axis to form fins that are curved along the second axis to conform to the curved passage, each fin comprising first and second sections for contacting the first and second parting sheets, respectively;
- and
- first and second diffusion bonds formed along respective entire lengths of the first and second sections, respectively, of a fin to diffusion bond the respective entire lengths of the first and second sections of the fin to the first and second parting sheets, respectively.
1 more element
A method of assembling a conformal heat exchanger, the method comprising:
- forming a fin sheet flat and corrugated along a first axis to form fins extending along a second axis perpendicular to the first axis;
- interposing the fin sheet between parting sheets;
- executing field assisted sintering technology/spark plasma sintering (FAST/SPS) processing to form diffusion bonds along respective entire lengths of each fin to diffusion bond the respective entire lengths of each fin to the parting sheets;
- and
- imparting a curvature to the parting sheets and the fin sheet along the second axis with the diffusion bonds surviving the imparting.
