The invention relates to an explosion-proof housing (10), in particular, of protection-type design "pressure-resistant enclosure". An interior (13) of the housing (10) is entirely sealed off from the surroundings (13) by housing walls (11). Electric and electronic components (14) are arranged in the interior (13). In order to cool these components, a ventilator (18) is arranged in the interior (13) and induces a cooling flow S in the interior (13). The heat transfer of the gas present in the interior (13) is thereby improved along at least one cooling body (24, 30) and/or along at least one housing wall (11) outwards towards the surroundings (12). Furthermore, the build-up of gas layers with different temperatures is avoided in the interior (13). |
