Abstract
A modular heat shield and heat spreader (“MHS”) includes top and bottom panels, and a plurality of thermally conductive pillars located between the panels and which support the top panel. A continuous pool of liquid between the panels surrounds some portion of the pillars. Heat to which the top panel is exposed is conducted through the top panel and at least some of the pillars. The heat changes the phase of some of the liquid to a vapor, which spreads the heat to an area larger than that of the heat source and thereby dissipates the heat away from the source at a lower heat flux than that associated with the flux from the source. The MHS preferably includes wicking material on some of the pillars and on the underside of the top panel, such that the wicking material is saturated with the liquid and heated by the conducted heat.
