The invention relates to a housing structure for electrical and/or electronic devices for outdoor installation. Resistance to extreme weather conditions is achieved by the invention in that the electrical and/or electronic components of the device are fitted in a dust and sprayproof inner cubicle (IP66), itself fitted inside a sprayproof outer cubicle (IP44), with a space between all their faces, there is an air heat exchanger in the inner cubicle, to the input circuit of which the heated air generated in the inner cubicle can be fed via circulating fans and the output circuit of which is connected to the inner chamber of the outer cubicle, and, for the purposes of cooling the inner cubicle, a controlled cooling stream of air passes through the outer cubicle, a part of which passes the output circuit of the air heat exchanger. |
