Abstract
The invention relates to an arrangement for a cooling system for cooling telecommunications equipment. This is installed in rack cabinets positioned one after the other. A duct section (4) is present beneath each rack cabinet. The duct section is so arranged as to direct at least one jet of cool air (6) upwards along the front wall of the rack cabinet. This is executed with openings through which the cooling air can reach the equipment. The duct section (4) is so arranged as to support the rack cabinet at four support points (4b1) at the respective ends of the duct section (4). In conjunction with this the walls of the duct section (4) are reinforced locally in order to withstand the load. In this way the duct section (4) exhibits a smaller flow cross section in the end areas (4d, 4e) than in a central area (4f) situated between the end areas. A gentle transition is provided between the central area (4f) and the flow surfaces of the end areas (4d, 4e). The front area (4a) of the duct section (4) lies in the same plane as the front wall of the rack cabinet. A number of upward-facing gills (4a1) is arranged in the central area (4f) in order to produce the upward-facing jets of cool air. The cool air unit produces an excess pressure inside the cooling duct, which has an approximately constant level of static pressure.
