盤を得ることができる。In the metal-clad control panel configured as described above, the storage device is cooled by natural convection 9 using the air from which dust is removed by the air filter 5 on the intake window side as a cooling medium. The function of preventing salt damage from the equipment is obtained. In addition, since air can flow through the space between the inner box and the outer box to prevent the temperature rise of the outer box from being received by direct sunlight, it can be prevented from being transmitted to the inside of the inner box. It is possible to obtain a metal-clad control panel in which the temperature in the panel is not excessively increased and the components in the panel are not easily damaged by salt and dust.

る。Furthermore, even if moist and dirty air permeating through the louver 17 with the air filter flows back into the outer casing 12 due to wind pressure, the air filter is located at a position different from the louver with the air filter. The function of preventing the fouled air from entering the inside of the inner box is obtained by being blocked by the inner box 13 having 15. Therefore, even if the metal-clad control panel configured as described above is installed outdoors where it is directly exposed to direct sunlight or wind and rain, the direct sunlight has little thermal effect on the storage device, and the temperature control can be advanced, and the dust control can be performed. Since the infiltration of the contaminated air containing salt, moisture and the like is prevented, the dustproof and waterproof performance can be enhanced to prevent the storage devices from being adversely affected.

利点が得られる。Further, if the mesh of the air filter 18 on the louver side with the air filter is formed finer than that of the air filter on the inner casing side, the dust or the water vapor containing salt which flows backward by the wind pressure can be obtained. Such a fouling substance is mainly collected by the filter 18 on the louver 17 side with the air filter having a fine mesh, so that the fouling substance can be prevented from entering the inner box, and the air filter on the inner box side can be prevented. By making the meshes 5 and 15 coarse, it is possible to prevent the air filter from hindering the natural convection of the air in the panel, and to obtain the advantage of minimizing the deterioration of the cooling performance of the equipment in the panel.

If the louver 17 with the air filter is provided on each of the A and 8B sides, the natural convection of the air in the panel is promoted and the temperature control of the storage device can be more advanced.
Furthermore, if the louver 17 with the air filter is provided with the rain hood 20 protruding outside the outer case, the air filter 18 is wetted by the wind and the rain, and the inside of the panel is protected. Since it is possible to more reliably prevent rainwater from being blown, there is obtained an advantage that the effect of moisture on the in-panel storage device can be reduced.
