Apparatuses, systems and methods associated with design of cold plates for cooling electrical systems are disclosed herein. In embodiments, a cold plate may include a base and a lid affixed to a side of the base via a braze joint, wherein the braze joint may extend around a perimeter of the lid. The lid may include a dam having a perimeter located inside of the perimeter of the lid, wherein the dam may be compressed against the side of the base and may be liquid-tight to the side of the base, and wherein a cavity may be located between the base and the lid within the perimeter of the dam to provide a circulation passage for a liquid coolant.
