In the server room air-conditioning efficiency structure in which is formed, a base-isolated floor skirt made of a sheet material is wound around part or all of the lower edge of the rack, and the lower edge of the rack It is characterized in that a part or all of the gap formed in (1) is shielded.

  In a structure in which a sheet material is wound around a part of the lower edge of the rack, the cooling air supplied to cool the equipment in the rack is a portion where the seismic isolation floor skirt is not disposed. Supplied from Since the seismic isolation floor skirt is arranged in the other part, the supplied cooling air does not pass below the rack and is used for cooling the equipment in the rack.

  On the other hand, in the structure in which the sheet material is wound around the entire lower edge of the rack, the cooling air for cooling the equipment in the rack is supplied from the opening for inserting and removing the equipment in the front of the rack. Is done. Further, since the lower edge portion of the rack is shielded by the sheet material, the cooling air blown from the floor surface of the passage is not supplied to the gap at the lower portion of the rack.

  In the server room air conditioning efficiency structure according to the invention of claim 2, the seismic isolation floor skirt is not provided in a portion facing the passage provided between the racks.

  When the server room floor has a double floor structure, air for cooling air conditioning is passed under the floor, and the floor surface is made of plate material with punched metal or other through-holes. Air is blown out. For this reason, the base-isolated floor skirt is not provided in the portion facing the passage, and the blown cooling air is introduced into the rack from the side facing the passage.

  In the server room air conditioning efficiency structure according to the invention of claim 3, the seismic isolation floor skirt is provided only at a portion facing the passage provided between the racks.

  Cooling air blown from the floor of the passage is prevented from being supplied to the lower gap of the rack by the seismic isolation floor skirt. The cooling air blocked by the base isolation floor skirt rises along the base isolation floor skirt, is supplied into the rack from the opening at the front of the rack, and is used for cooling the equipment apparatus accommodated in the rack. .

  In the server room air conditioning efficiency structure according to the invention of claim 4, the seismic isolation floor skirt is arranged in a rack row in which racks are arranged in parallel.

  In some cases, the racks may be installed alone, but in some cases, a large number of racks may be arranged in parallel to form a rack row. In this case, the gap is shielded by the seismic isolation floor skirt while leaving a part of the entire rack row.

  In the server room air conditioning efficiency structure according to the invention of claim 5, the seismic isolation floor skirt is provided with a flameproof property.

  In the server room, since heat is generated from the equipment accommodated in the rack, the seismic isolation floor skirt is heated. For this reason, it has a flameproof property so that it will not burn even if it is heated and exposed to a flame. Furthermore, nonflammability can be provided.

  In the server room air conditioning efficiency structure according to the invention of claim 6, the seismic isolation floor skirt is provided with antistatic properties.

  This prevents static electricity from being charged in the equipment device accommodated in the rack.

  Since the supplied cooling air does not pass below the rack, it is used for cooling the equipment in the rack, and the cooling air can be used effectively. For this reason, the air conditioning efficiency in the server room can be improved.

  According to the efficiency improving structure for air conditioning in the server room according to the invention of claim 2, the cooling air can be efficiently introduced into the rack.

For this reason, cooling air is supplied. As described above, the punching metal is used on the floor surface of the passage 3, and cooling air is blown out from here. Since the seismic isolation floor skirt 4 is not provided in the lower part of the rack 2 and facing the passage 3, the cooling air is introduced into the rack 2. Since the introduced cooling air cools the equipment in the rack 2 and rises in temperature by raising the temperature in the rack 2, a suction force acts on the cooling air supplied from the lower part, and the rack 2 Inhaled. For this reason, the cooling efficiency in the rack 2 is improved.

  In the above-described embodiment, the base isolation floor skirt 4 is not disposed on the lower edge facing the passage 3 of the rack 2. However, as shown in FIG. A structure may be provided in which the lower edge portion is wound around the whole. If the structure is not arranged on the side of the passage 3 of the rack 2, the cooling air blown from the floor surface is supplied to the gap G at the lower part of the rack 2, and the equipment housed in the rack 2 while rising in the rack 2 It is used for cooling the device. On the other hand, as shown in FIG. 4, in the structure in which the seismic isolation floor skirt 4 is also arranged on the side of the passage 3, the cooling air blown out from the floor surface enters the rack 2 from the portion facing the passage 3 of the rack 2. To be supplied. Since the opening for the operation | work which inserts / extracts an apparatus apparatus with respect to the rack 2 is formed in the part which faces the channel | path of the rack 2, the said cooling air is supplied in the rack 2 from this opening.

  Furthermore, as shown in FIG. 5, it is also possible to adopt a structure in which the seismic isolation floor skirt 4 is arranged only at the lower edge facing the passage 3 of the rack 2. In this structure, the cooling air supplied to the gap G at the lower part of the rack 2 is supplied into the rack 2 without passing through the gap G, and is used for cooling the equipment device accommodated in the rack 2.

  According to the present invention, even when a gap is formed between the seismic isolation floor and the rack, the cooling air can be reliably supplied into the rack, so that the equipment in the rack can be reliably cooled. Moreover, since the sheet material is provided at the lower part of the rack, it can be mounted even in an existing server room, which contributes to the improvement of the air conditioning efficiency in the existing server room.
