Abstract
Abstract A ventilating device is provided for ventilating an electronic apparatus such as a computer. The device includes a housing having a top wall with a first ventilating aperture therein, and further includes a floor, a pair of side walls extending between said floor and said top wall, and an end wall closing one end of the housing. The housing is open at one end. The device further includes a fan unit secured in the housing adjacent the top wall in substantial alignment with the ventilating aperture and spaced above the housing floor, whereby the fan unit pulls air in through one of the ventilating aperture and open end expels air through the other thereof to facilitate the flow of air through the electronic apparatus.
