Abstract
A method of manufacturing a heat exchanger core from glass ceramic matrix composite includes placing one or more reinforcing fibers around one or more mandrels into a mold cavity. A glass matrix material infiltrates the one or more reinforcing fibers to produce an infiltrated core and the one or more mandrels is removed to create one or more passages passing through the infiltrated core.
Claims20
A method of manufacturing a heat exchanger core from glass ceramic matrix composite, wherein the method comprises:
- placing one or more reinforcing fibers around one or more mandrels into a mold cavity;
- infiltrating the one or more reinforcing fibers with a glass matrix material to produce an infiltrated core;
- and
- removing the one or more mandrels to create one or more passages passing through the infiltrated core.
A heat exchanger comprising:
- one or more tubular regions, wherein each tubular region of the one or more tubular regions comprises:
- a passage with a radially inner surface;
- and
- a radially outer surface;
- one or more reinforcing fibers between the radially inner surface and the radially outer surface of each tubular region;
- a glass matrix material infiltrating the one or more reinforcing fibers;
- a first pattern formed into the radially inner surface of each tubular region;
- and
- a second pattern formed into the radially outer surface of each tubular region.
