An exemplary cold plate housing defines an inlet port and an outlet port. A plurality of foam strips are disposed in the housing. Each foam strip suitably has pore size of no more than around 50 micrometers and porosity of at least around 80 percent. The foam strips are arranged within the housing so coolant is flowable through a width of the foam strips. Pore size may be around 35 micrometers and porosity may be around ninety percent. Foam may be a ceramic foam that includes silica, aluminum oxide, and aluminum borosilicate fibers. A plurality of plenums may be disposed within the housing. In an application, at least one exemplary cold plate is disposed within a heat exchanger housing intermediate a heat exchanger inlet port and a heat exchanger outlet port such that heat exchanger fluid flows directly over both sides of the cold plate.
