Claim 0:
1. A circuit housing apparatus, comprising:
a cuboid housing assembly (housing assembly) that includes an interior portion;
an air plenum piece located within the interior portion of the housing assembly to form a first interior portion and a second interior portion, the air plenum piece substantially isolating the first interior portion from the second interior portion except for a hole in the air plenum piece that fluidly interconnects the first interior portion to the second interior portion;
an electronic circuit that generates heat;
a fan located in substantially co-axial alignment with the hole in the air plenum piece, and wherein
the fan is adapted to draw cooling air from outside the housing assembly into fluid contact with the heat generating electronic circuit, whereupon the cooling air convectively receives heat from the electronic circuit to warm the cooling air, and wherein
the fan is further adapted to force the warmed cooling air to outside the housing assembly.
