Abstract
An additively manufactured heat exchanger is provided and includes first and second inlet headers which are interlaced with one another, first and second outlet headers which are interlaced with one another and a core. The core is interposed between a pair of the first and second inlet headers and a pair of the first and second outlet headers. The core includes first pathways by which a first fluid flows from the first inlet header to the first outlet header and second pathways disposed in thermal communication with the first pathways and by which a second fluid flows from the second inlet header to the second outlet header.

An additively manufactured heat exchanger, comprising:
- first and second inlet headers which are interlaced with one another;
- first and second outlet headers which are interlaced with one another;
- and
- a core interposed between a pair of the first and second inlet headers and a pair of the first and second outlet headers, the core comprising:
- first pathways by which a first fluid flows from the first inlet header to the first outlet header;
- and
- second pathways disposed in thermal communication with the first pathways and by which a second fluid flows from the second inlet header to the second outlet header.
An additively manufactured heat exchanger, comprising:
- first and second inlet headers which are interlaced with one another;
- first and second outlet headers which are interlaced with one another;
- and
- a core interposed between a pair of the first inlet header and the second outlet header and a pair of the second inlet header and the first outlet header, the core comprising:
- first pathways by which a first fluid flows from the first inlet header to the first outlet header;
- and
- second pathways disposed in thermal communication with the first pathways and by which a second fluid flows from the second inlet header to the second outlet header.
A method of additively manufacturing a heat exchanger, the method comprising coincidental operations of:
- building up layers of first and second inlet headers to be interlaced with one another by laser powder bed fusion (PBF-L);
- building up layers of first and second outlet headers to be interlaced with one another by PBF-L;
- and
- building up layers of a core interposed between a pair of the first and second inlet headers and a pair of the first and second outlet headers by PBF-L such that the core comprises:
- first pathways by which a first fluid flows from the first inlet header to the first outlet header;
- and
- second pathways disposed in thermal communication with the first pathways and by which a second fluid flows from the second inlet header to the second outlet header.
