THERMALLY CONDUCTIVE MICROTUBES FOR EVENLY DISTRIBUTING HEAT FLUX ON A COOLING SYSTEM

Abstract:

An electronics cooling system includes a printed circuit board (PCB) assembly having a heat generating component connected to a base. A plurality of thermally conductive microtubes are connected to the PCB assembly with a first spatial density. The plurality of thermally conductive microtubes are connected to a heat plate of a cooling system with a second spatial density to evenly spread the heat flux of the PCB assembly over the heat plate.
