Description

  The present invention relates to an electric equipment storage box provided with a louver for ventilation.

  In order to suppress the rise in internal temperature due to heat dissipation from the equipment stored in the electrical equipment storage box, a structure has been conventionally used to provide ventilation by providing a louver on the wall of the electrical equipment storage box (patented) Reference 1).

  Conventionally, the louver provided on the wall surface of the electrical equipment storage box always has an open structure, which is inconvenient when the internal temperature is not raised and ventilation is not required. In addition, there may be a case where a space portion without internal equipment is left for future expansion of a server room such as a data center. In such an unmounted portion, the cold air sucked from the front surface of the cabinet escapes to the back side as it is without being heated. Moreover, since the flow resistance inside the cabinet is small in the unmounted portion, a large amount of cool air flows out from the mounted portion, leading to a decrease in cooling efficiency.

  As a louver structure provided with an opening / closing mechanism, a louver device provided in a window portion of a house, wherein two flat plates are provided with a plurality of long strip-shaped openings, and a louver is formed, and the two louvers are slidably stacked. A technique for adjusting the opening area by disposing and sliding is disclosed (Patent Document 2).

  However, when the louver structure described in Patent Document 2 is adopted for an electrical equipment storage box, the inside of the electrical equipment storage box can be visually recognized from the opening in the open state, and it is not preferable because the internal secrecy cannot be secured. There was no problem.
