A heat exchanger and method of making same are disclosed. In another aspect, a method of making a heat exchanger includes sintering powder metal and hot isostatic pressing of the powder metal. Moreover, an aspect of the present heat exchanger apparatus employs plates in a stacked arrangement with supercritical-COflowing between the plates and between adjacent fins. Still another aspect of a heat exchanger apparatus is made of a nickel-based alloy.

Heat exchanger and method of making same

The disclosure relates to a method for forming a metal article by additive manufacturing and related apparatus for performing the method. A metal particle suspension including a UV-curable polymeric resin liquid medium, and metal particles distributed throughout the liquid medium is deposited and cured by spatially selective exposure to UV radiation in a layer-by-layer process. Metal particle size can be selected in combination with the applied layer thickness to ensure complete cure throughout the applied layer while providing a high print speed and high spatial resolution. Intermittent or periodic partial curing of an applied layer can be used to maintain a homogeneous distribution of metal particles in the applied layer prior to full curing. The final product is achieved after sintering, which removes the cured binder in a debinding step and also provides the desired final article at close to the full density.
