Pattern bonded finned cold plate
An apparatus includes a fin pack of parallel plates that protrude from a base, a lid attachable to the fin pack opposite the base, and a brazing material painted onto the lid only in a plurality of wettable regions. The lid is positioned against the fin pack, opposite the base, with portions of the plurality of regions contacting edges of the parallel plates. The lid is brazed to the fin pack without intrusion of the brazing material between the parallel plates. This is accomplished by obtaining a lid to be attached to a fin pack of parallel plates that protrude from a base, painting the lid with the brazing material only in a plurality of wettable regions, positioning the lid against the fin pack, opposite the base, with portions of the plurality of regions contacting edges of the parallel plates, and brazing the lid to the fin pack.
