ABSTRACT:
A heat spreading apparatus includes a body with an interior surface defining a void. The interior surface includes randomly configured high aspect ratio micro surface capillaries. Preferably, the micro surface capillaries are intergranular and intragranular capillaries that are less than 200 microns and have an aspect ratio of at least 1:1. All horizontal and vertical surfaces of the interior surface include the high aspect ratio micro surface capillaries. The high aspect ratio micro surface capillaries promote fluid transport and heat transfer.
