Abstract
A heat exchanger includes a central spar, a body, and a mounting arm. The central spar is disposed along an axial centerline of the heat exchanger. The body is disposed around the central spar. The body includes an exterior wall and heat exchanger core disposed within the exterior wall and integrally formed with the central spar. The mounting arm is integrally formed with and extends radially from the central spar. The mounting arm extends through a portion of the body and is integrally formed with the central spar via additive manufacturing.
Claims16
A heat exchanger comprising:
- a central spar disposed along an axial centerline of the heat exchanger;
- a body disposed around the central spar, wherein the body comprises:
- an exterior wall;
- and
- a heat exchanger core disposed within the exterior wall and integrally formed with the central spar;
- and
- a mounting arm integrally formed with and extending radially from the central spar, wherein the mounting arm extends through a portion of the body, wherein the mounting arm is integrally formed with the central spar via additive manufacturing.
A method of manufacturing a heat exchanger, the method comprising:
- forming, with layer-by-layer additive manufacturing, a central spar disposed along an axial centerline of the heat exchanger;
- forming, with layer-by-layer additive manufacturing, a body disposed around the central spar, wherein the body comprises:
- an exterior wall;
- and
- a heat exchanger core disposed within the exterior wall and integrally formed with the central spar;
- and
- forming, with layer-by-layer additive manufacturing, a mounting arm integrally formed with and extending radially from the central spar, wherein the mounting arm extends through a portion of the body, wherein the mounting arm is integrally formed with the central spar via additive manufacturing.
