The invention relates to an arrangement for cooling equipment and network cabinets, particularly server cabinets, in which the fans are integrated into a door. The resulting fan door, in the closed position, covers an access area of the rear of the cabinet and longitudinally adjacent to the fan door is arranged in fixed manner an air-to-fluid heat exchanger, whilst covering a residual area of the rear of the cabinet and to which is articulated the fan door. The heat loss given off to a cooling liquid, particularly cold water, in the heat exchanger is removed via a pipe system outside the cabinet installation area and rigid connecting pipes of a gas-tight material can be used for the connection of the heat exchangers of the individual cabinets to the building-side pipe system.
