Air managing system

Abstract

An air-managing system for a heat-generating, image-producing broadcast device mounted in a smoke laden or dust-laden environment, including a container including enclosed walls and an image broadcast aperture, to form an interior for containing the heat-generating, image-producing, broadcast device and further including inlet slots formed in the container walls, for receiving air into the container interior, a container exhaust opening, and a fan in communication with the exhaust opening for drawing air through the interior and pushing it out the container, a sealed enclosure comprising a top panel, bottom panel, opposed side panels and spaced-apart front and back panels in sealed engagement forming an interior therein large enough to house the container therein leaving space between the container walls and the enclosure panels, means in the sealed enclosure to align the image broadcast aperture with an image projection opening in one of the sealed enclosure panels, air-transfer means in communication with the sealed enclosure for pumping air, outside of the enclosure, into the sealed enclosure and developing a positive air pressure therein, and an air exhaust port formed in the sealed enclosure and connected to the fan in communication with the exhaust opening of the container to confine the flow of pressurized air in the enclosure means to a path passing through the broadcast device.
