Abstract: An apparatus for holding a cover in a closed orientation substantially covering a chassis face of a unit; the unit containing equipment in an equipment volume; the equipment volume being partially bounded by the chassis face; includes: a positioning structure coupling the cover with the unit for selectively situating the cover in the closed orientation or in an other orientation; and a latching structure configured for latchingly engaging the chassis face and the cover for holding the cover in the closed orientation when the latching structure is in a first orientation. The latching structure does not engage the chassis face and the cover when the latching structure is in a second orientation. The latching structure is situated substantially entirely outside the equipment volume.

Abstract: An apparatus for transferring heat from an electrical module includes: (a) a thermally conductive base member having a plurality of edges establishing a polygonal perimeter and having a first side for presentation toward the electrical module; and (b) a heat transferring structure integrally formed with the base member and extending from a second side of the base member opposite from the first side. The heat transferring structure occupies less than all of the second side and establishes a margin substantially about the perimeter.
