Hybrid ceramic core cold plate

A heat exchanger comprising:

• a heat exchanger housing defining at least one heat exchanger inlet port for a first fluid and at least one heat exchanger outlet port for the first fluid;
• and
• at least one cold plate disposed within the heat exchanger housing between the heat exchanger inlet port and the heat exchanger outlet port such that the first fluid is flowable in thermal communication with the at least one cold plate, the at least one cold plate including:
• a cold plate housing including a top plate and a bottom plate, the cold plate housing defining at least a first cold plate inlet port for a second fluid and at least a first cold plate outlet port for the second fluid;
• a first plurality of foam strip assemblies disposed in the cold plate housing, each foam strip assembly of the first plurality of foam strip assemblies comprising a first foam strip that is coupled to the top plate and a first spacer coupled to a portion of the first foam strip that is opposite the top plate;
• and
• a second plurality of foam strip assemblies disposed in the cold plate housing, each foam strip assembly of the second plurality of foam strip assemblies comprising a second foam strip that is coupled to the bottom plate and to the first spacer of an adjacent first foam strip of the first plurality of foam strip assemblies;
• wherein the first and second pluralities of foam strip assemblies are arranged within the cold plate housing to create a plurality of inlet plenums between a portion of adjacent first lengths of the first and second pluralities of foam strip assemblies and to create a plurality of outlet plenums between opposite first lengths of the first and second pluralities of foam strip assemblies, such that, when the second fluid is received at the first cold plate inlet, the second fluid is forced from the first cold plate inlet port into the plurality of inlet plenums through foam strips of the first and second pluralities of foam strip assemblies and into the plurality of outlet plenums and into the first cold plate outlet port.

A cold plate comprising:

• a housing including a top plate and a bottom plate, the housing defining first and second inlet ports and first and second outlet ports;
• and
• a first plurality of foam strip assemblies disposed in the housing, each foam strip assembly of the first plurality of foam strip assemblies comprising a first foam strip that is coupled to the top plate and a first spacer coupled to a portion of the first foam strip that is opposite the top plate;
• and
• a second plurality of foam strip assemblies disposed in the housing, each foam strip assembly of the second plurality of foam strip assemblies comprising a second foam strip that is coupled to the bottom plate and to the first spacer of an adjacent first foam strip of the first plurality of foam strip assemblies,
• wherein the first and second pluralities of foam strip assemblies are arranged within the housing to create a plurality of first inlet plenums, a plurality of first outlet plenums, a plurality of second inlet plenums, and a plurality of second outlet plenums configured such that, when coolant is received at the first inlet port, the coolant from the first inlet port is forced from the plurality of first inlet plenums through foam strip assemblies into the plurality of first outlet plenums and into the first outlet port and coolant from the second inlet port is forced into the plurality of second inlet plenums through foam strip assemblies into the plurality of second outlet plenums and into the second outlet port.
