Abstract: Electronics cabinet comprising an enclosure (1) with an interior space (2) where electronic parts, such as circuit cards and the like, can be mounted, and a cooling system (3) arranged as a substantially integral assembly with the enclosure in the immediate vicinity of its interior space for cooling the interior space. The cooling system (3) comprises means for internal air circulation within the interior space, for conveying an external air circulation separated from the internal air circulation into and out of the cooling system and for cooling the air in the internal circulation. The means for conveying the internal and/or external air circulation comprise a body (4) made from a foamed material with a flow channel (5, 6, 7) formed in it, through which at least part of the internal and/or external air circulation is passed.
