Abstract

A clam shell module cover for printed circuit boards (PCB) has been designed for use in Boeing’s AECM cabinet. The cover utilizes materials with high thermal conductivity and cools the PCB by conducting the heat to a cold plate interface. Materials were compared and aluminum 6061-T6, aluminum 3003, and annealed pyrolytic graphite (APG) were chosen. A prototype was built and tested using aluminum 6061-T6 which was able to dissipate 57.7% of the projected wattage. Issues may include unforeseen complications in assembly along with components performing at lower levels than specified by manufacturers. The APG prototype was unable to be tested since it was not completed and shipped in time. Aluminum 3003 was found to be too scarce and expensive for the .75” plate needed for the prototype.
