Abstract
An explosion-proof housing having external walls, which enclose a housing interior so as to be proof against ignition penetration relative to an atmosphere at risk of explosion. At least one insert is arranged in at least one outer wall. The insert facilitates a gas flow between the housing interior and an environment around the housing. The at least one insert is configured in such a way that a gas flow having a sufficient mass flow or volumetric flow rate is permitted, but a flow connection which is proof against ignition penetration is produced. Attached to the outer wall having the at least one insert is a guiding means which together with the relevant outer wall delimits a flow channel. The flow channel defines a main flow direction of a main gas flow through the flow channel substantially parallel to the directly adjoining outer wall. In this way, the gas exchange between the environment and the housing interior can be improved and facilities arranged in the housing interior can be cooled.
