Abstract
Official abstract text for this publication.
A heat exchanger and method for making a heat exchanger assembly is described, involving generating a digital model of a heat exchanger assembly that comprises a heat exchanger core within a housing. The digital model is inputted into an additive manufacturing apparatus or system comprising an energy source. The additive manufacturing apparatus applies energy from the energy source to successively applied incremental quantities of a metal powder, which fuses the powder to form incremental portions of the heat exchanger core and housing according to the digital model. Unfused or partially fused metal powder is enclosed in a first region of the heat exchanger assembly between the heat exchanger core and the housing.
First claim
Opening claim text (preview).
What is claimed is: 1. A heat exchanger assembly, comprising a housing of the heat exchanger assembly; a heat exchanger core within the housing; and unfused or partially fused metal powder enclosed in a first region of the heat exchanger assembly between the heat exchanger core and the housing. 2. The heat exchanger assembly of claim 1 , wherein the first region comprises unfused metal powder. 3. The heat exchanger assembly of claim 1 , wherein the first region comprises partially fused metal powder. 4. The heat exchanger assembly of claim 1 , wherein the first region encases the heat exchanger core. 5. The heat exchanger assembly of claim 1 , further comprising a second region between the heat exchanger core and the housing that is free of metal powder. 6. The heat exchanger assembly of claim 1 , wherein the assembly further comprises a second region between the heat exchanger core and the housing that comprises partially fused metal powder at a different density than the metal powder in the first region. 7. The heat exchanger assembly of claim 1 , further comprising an enclosure separating the first region from one or more other regions between the heat exchanger core and the housing. 8. The heat exchanger assembly of claim 1 , wherein the heat exchanger core comprises a heat rejection side flow path and a heat absorption side flow path in a heater core skin.
