ABSTRACT:
A structural panel has thin inner and outer facesheets bonded to a lightweight structural interior core of a honeycomb material. The inner facesheet is for receiving equipment that generates heat to be dissipated and the outer facesheet is adapted to dissipate such heat, such as by radiation. A plurality of closely-spaced heat pipes interior to the panel are thermally coupled to each other and to the inner facesheet for receiving heat from the equipment mounted thereon. A plurality of spaced-apart heat pipes interior to the panel are at about right angles to the closely-spaced heat pipes and are thermally coupled to the outer facesheet and to the closely-spaced heat pipes proximate their intersections therewith. Heat to be dissipated flows along short, direct and efficient paths from the equipment to the inner facesheet, to the closely-spaced heat pipes, to the spaced-apart heat pipes and to the outer facesheet from whence it is dissipated.
