Clilmate control of an outdoor cabinet

摘要

The present invention relates to an outdoor cabinet (1) housing electrical equipment (27). The cabinet comprises two substantially concentrically arranged casings (23, 33) forming an intermediate space (35). This space is used as a duct for an external air flow. An external air inlet (15) and a heat exchanger unit (57) is arranged in a door (11) of the cabinet and at least one external air fan (71) is arranged for blowing air into the space. External air outlets (17) are arranged at a side of the cabinet opposite the door side (11). Thus an external air flow entering the cabinet through the external air inlet (15) has to travel a long distance until it reaches the external air outlets (17). Hereby, sound generated by the fan motion (71) is effectively damped. At the same time the external air flow inside the duct (35) is removing the heat contribution due to solar radiation.
