Claim:
An enclosure for retaining and operating a plurality of electronic modules, the enclosure comprising: a housing having front, side, upper, lower, and rear walls, said housing enclosing an inner volume; an inner wall running between said side walls and attached to said lower wall, said inner wall positioned between said front and back walls, said inner wall splitting said inner volume into a first inner volume and a second inner volume; said inner wall extending from the bottom wall to a height less than that of the height of said top wall, said inner wall at least in part defining an environmental opening between the first inner volume and the second inner volume, said inner wall blocking a lateral airflow across the inner volume; a vent disposed through the rear wall; openings disposed in the housing, said openings disposed into the first inner volume, operable to allow an airflow into the first inner volume; and an environmental flow mechanism, coupled in proximity to said vent, the environmental flow mechanism oriented to create an outgoing airflow from an upper portion of said housing through said vent; whereby the interaction of the airflow from the upper portion of said housing and blocking of the lateral airflow by said inner wall produces a flow of air from said openings near the bottom of said housing, upwards to said environmental opening.
