The invention concerns a switchgear cabinet with a heat exchanger which is built into a wall element, for example a side wall, and has an internal circuit and an external circuit. The switchgear cabinet with built-in heat exchanger can be produced with relatively high degrees of protection (IP55, IP66) in that, built into an opening in the side wall, is an integral heat sink which has vertical inner cooling ribs projecting into the interior of the switchgear cabinet and vertical outer cooling ribs lying on the cabinet exterior. An inner fan draws air out of the cabinet interior and, in the upper region, feeds it to the inner ducts which are formed between the inner cooling ribs and in which the air drawn in is guided into the lower region of the inner ducts and from there out into the cabinet interior. |
