ABSTRACT:
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.
