Abstract: A method of making a cold plate (10) includes the steps of positioning a finstock (16) structure in a cavity (14) of a substrate; (12) and applying a cover(18) to the finstock (16) structure and substrate (12), wherein the applying step comprises ultrasonically additive manufacturing the cover (18) to the substrate (12) and the finstock structure (16), whereby the cover (18) joins with the substrate (12) and the finstock structure (16). The resulting cold plate assembly (10) includes a substrate (12) having a cavity (14), a finstock structure (16) within the cavity (14), and a cover (18) closing the finstock structure (16) within the cavity (14), the cover (18) being integrally joined to the substrate (12) and to the finstock structure (16).
