Abstract
A printed circuit heat exchanger (PCHE) and methods for fabricating a PCHE for use in facilitating heat transfer includes providing a plurality of plates that each include a plurality of densely spaced channels configured to channel fluid through the PCHE. The method also includes applying a protective coating to pre-defined regions identified on at least one of the plurality of plates, wherein the protective coating facilitates extending a useful life of the PCHE, and coupling at least two of the plurality of plates together to create the PCHE.
Claims18
A method of fabricating a printed circuit heat exchanger (PCHE) for use in facilitating heat transfer, said method comprising:
- providing a plurality of plates that each include a plurality of densely spaced channels configured to channel fluid through the PCHE;
- applying a protective coating to pre-defined regions identified on at least one of the plurality of plates, wherein the protective coating facilitates extending a useful life of the PCHE;
- and
- coupling at least two of the plurality of plates together to create the PCHE.
A method of fabricating a printed circuit heat exchanger (PCHE) for use in facilitating heat transfer, said method comprising:
- applying a protective coating to pre-defined regions on each of a plurality of plates that include channels defined thereon via a chemical etching process;
- and
- coupling at least two of the plurality of plates together via a diffusion bonding process to create the PCHE.
A printed circuit heat exchanger (PCHE) comprising:
- a plurality of plates coupled together via a diffusion bonding process, wherein each of the plates includes a plurality of channels defined thereon via a chemical etching process, and wherein each of the plates also includes a protective coating only applied to pre-defined regions of each plate, the plates coupled together such that fluid flowing through the channels during use of the PCHE effectuates heat transfer within the PCHE.
