THERMAL SPREADER WITH PHASE CHANGE THERMAL CAPACITOR FOR ELECTRICAL COOLING

A cooling assembly comprises an electronic component, a thermal spreader, a cold plate, and a phase change thermal capacitor. The thermal spreader conducts heat freely between the electronic component, the phase change thermal capacitor, and the cold plate. The cold plate dissipates heat. The phase change thermal capacitor stores undissipated heat in a phase transition of a phase change material.
