A metal cabinet 10 for containing electrical apparatus and assemblies includes a roof (14, Fig 2), walls (12a, 12b, Fig 3) and at least one closure 16a, 16b which define an interior space (25, Fig 4)) of the cabinet 10. The interior space (25, Fig.4) of the cabinet 1 is provided with at least one container (28, Fig.3) which contains a phase change material (PCM). The PCM is selected to have a desired melting point such that it is able to absorb heat energy and maintain the temperature of the interferer space below a predetermined maximum. The container of PCM (28, Fig.3) may be mounted to an interior face of a wall, closure or roof of the cabinet within a recess. The cabinet 10 may be provided with a plurality of containers of PCM wherein the phase change temperatures of the containers are different. The external faces of one or more walls or closures may be provided with louver panels 20. |
