THERMAL MANAGEMENT DEVICE FOR HEAT GENERATING POWER ELECTRONICS INCORPORATING HIGH THERMAL CONDUCTIVITY PYROLYTIC GRAPHITE AND COOLING TUBES

摘要

The present invention is a system for cooling high power, heat generating devices. The system includes a metal matrix composite (AlSiC) having a coefficient of thermal expansion substantially equal to that of the heat generating device. The metal matrix composite (MMC) includes interior cooling channels and at least one Pyrolytic Graphite insert laterally positioned against the cooling channels. The heat generating device is placed on the metal matrix composite top surface in a substantially parallel relationship with the Pyrolytic Graphite insert surface area for maximum heat transfer efficiency.
