Phase change cooled power electronic module

A power electronic module is cooled by a phase change heat spreader or cooling device. The module may include switched or unswitched devices, such as power transistors, diodes, and so forth, forming circuits such as rectifiers, inverters, converters, or the like, or portions of such circuits.

Beschreibung
Zusammenfassung:	A power electronic module is cooled by a phase change heat spreader or cooling device. The module may include switched or unswitched devices, such as power transistors, diodes, and so forth, forming circuits such as rectifiers, inverters, converters, or the like, or portions of such circuits. Heat is transferred to the heat spreader in which a continuous phase change cycle takes place to cool the circuit components. The heat spreader may extend over an area sufficient to reduce the temperature of the components, and ultimately will render portions of the overall structure more isothermal.
