Abstract
The present invention pertains to a switchgear cabinet for accommodating electronic plug-in modules with an interior in which the heat-generating plug-in modules can be inserted one on top of another, a roof area arranged above the interior and a base arranged underneath the interior and that forms a base area. The switchgear cabinet furthermore comprises an air channel that is arranged to the side of the interior and connects the roof area to the base area. A closed cooling circuit within the switchgear cabinet serves for carrying off the heat generated by the plug-in modules. A fan arranged in the roof area takes in air from the interior and blows this air into the air channel. The heated air from the air channel flows around a heat exchanger arranged in the base in such a way that the air is cooled and the thereby produced cooling air is admitted into the interior from below and flows through this interior vertically upwards.
