A cold plate includes two flow-wise isolated coolant (or refrigerant) passages (or sets of passages) originating at the center of the cold plate and terminating at an edge for use in conjunction with separate refrigeration systems. The cold plate passages are centrally fed by the refrigeration system to create a cooling gradient radiating from the center of the cold plate to its edges. The center-fed cold plate provides a more even temperature gradient across the thermal source. The cold plate passages do not permit flow communication between distinct coolant (or refrigerant) paths. This permits two distinct cooling systems to operate either dually or in a redundant manner. Nonetheless, flow isolation is achieved while still maintaining tight thermal coupling between each path and the object, such as an electronic computer processor module, to be cooled.

[ What is claimed is:] [1.] A method of fabricating a cold plate comprising:boring a plurality of passages in a thermal mass;forming a plurality of cooling branches wherein each branch is formed by mechanically linking a plurality of said passages in serial communication with each other and each said branch providing a fluid communication path between a central portion and a non-central portion of said thermal mass;forming a first cooling circuit by providing an first input conduit from a first cooling system to at least one of said cooling branches at said central portion of said thermal mass; andfurther forming said first cooling circuit by providing a first output conduit from said cooling branches at said non-central portion of said thermal mass to said first cooling system.
