Abstract
A thermal core (10) including aluminum layer (12) held between two molybdenum layers (14) for dissipating heat from a plurality of chip carriers (22). Core (10) has the ability to withstand excessive vibrational loads while being lightweight. Bonding molybdenum/aluminum/molybdenum layers (12, 14) creates a core (10) having an increased stiffness factor which surpasses military vibrational requirements. Additionally, due to the low density of porous aluminum layer (12), weight limitations set forth by the military can also be met.
