A cold plate includes two flow-wise isolated coolant (or refrigerant) passages (or sets of passages) for use in conjunction with separate refrigeration systems. The cold plate passages do not permit flow communication between distinct coolant (or refrigerant) paths. This permits two distinct cooling systems to operate 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.
