Switch cabinet with air-conditioning device

The invention relates to a control cabinet (10) with an air-conditioning device (21). The air conditioning apparatus (21) has at least one preferably linearly in a direction of extension (E) extending air duct (22). The air channel (22) extends along to be conditioned and in particular components to be cooled (12) in the interior (11) of the cabinet (10). A first end (23) of the air duct (22) is connected to an air supply means (26) allows air into the air channel (22). The opposite second end (24) of the air duct (22) is closed preferably entirely by a closing wall portion (25). A wall portion, for example, a side wall portion (35) of the channel wall (33) of the air duct (22) has a plurality of outflow openings (37). From these air flows targeted from the air duct (22) to or onto the components (12). It is achieved by simple means a specific climate.
