Abstract

PROBLEM TO BE SOLVED: To provide a structure for improving air-conditioning efficiency in a server room to prevent degradation of air-conditioning efficiency of the server room even when an empty rack which does not accommodate a server, exists in the server room.SOLUTION: An empty rack 1a is sealed by placing a shielding member 2 on an opening portion of the empty rak 1a, and placing the same also on side plates of the rack 1a with through holes such as punching metal. As warm air used for cooling a server in a rack 1a near the empty rack 1a does not flow into the empty rack 1a or pass therethrough, a desired flow channel of air-conditioning air can be formed, and degradation of the air-conditioning efficiency in the server room can be prevented.

Description

  The present invention relates to a structure for improving the efficiency of air conditioning in a server room in which the flow path of conditioned air is appropriate in order to improve the efficiency of air conditioning in the server room.

  With the recent diversification and complexity of network networks, network devices and servers are installed in dedicated server rooms. In this type of server room, not only measures such as earthquake, fire and security are taken, but also air conditioning management is an important countermeasure issue, and an efficient air conditioning system is desired.

  By the way, in installing the server room, for example, in Patent Document 1, as a server room that can be installed and removed easily and quickly, a space for installing the server and a temperature for adjusting the server are described.

  In the server room, as described in Patent Document 2, rack rows are arranged by a number of racks that accommodate servers. Not all of these racks contain servers, and there are empty racks that do not contain servers. In particular, in the newly established server room, there are a large number of empty racks in order to consider the expansion of the subsequent facilities.

  On the other hand, as described above, in order to appropriately manage the air conditioning of the server room, the air conditioning efficiency is also designed from the server room design stage. At this time, the server room rack is designed to accommodate the server. For this reason, in order to efficiently perform air conditioning, the server needs to be accommodated in a rack in the server room. In other words, the air-conditioned air supplied into the rack to cool the server is efficiently discharged from the server room after passing through the rack, cooled, and then supplied for air-conditioning of the server room.

  However, as described above, when there is an empty rack in the server room, since there is no server to be cooled, conditioned air passes through the rack.

  FIG. 5 shows the flow of the conditioned air when the server is accommodated in the rack 1. The flow of the cold air Ac is indicated by the white arrow, and the hatched line is used for cooling the server by the arrow. The flow of warm hot air Ah is shown respectively. In addition, as shown in FIG. 7, the rack 1 has an opening for inserting and removing the server in the front surface, and a so-called through-hole of an appropriate size is formed in the side plate of the other wall. Punching metal is used. As shown in FIG. 8, a plurality of shelf boards 11 can be installed at arbitrary height positions in the rack 1, and the server is placed on the shelf board 11 and installed. As shown in FIG. 5, the cold air Ac supplied from the front surface of the rack 1 in which the server is accommodated is cooled from the front surface of the rack 1 and then discharged from the through holes on the side surface and the rear surface of the rack 1. As shown in the figure, the hot air Ah discharged from the rear surface is merged with the hot air Ah discharged from the rear surface of the other rack 1 and rises and is sucked into an opening (not shown) formed on the ceiling surface of the server room. Then, the air is returned to the air conditioner through the duct in the ceiling and cooled, and then blown into the server room.

  On the other hand, as shown in FIG. 7, when there is an empty rack 1a in which no servers are accommodated, as shown in FIG. 6, the hot air Ah after cooling the servers in the rack 1 becomes empty rack 1a. Will be discharged from the front side through the empty rack 1a. At this time, the air flowing from the front surface of the empty rack 1a collides with the cold wind Ac. For this reason, since the hot air Ah is not returned to the air conditioner and stays in the empty rack 1a, the air conditioning efficiency of the server room may be reduced.

  Accordingly, an object of the present invention is to provide a structure for improving the efficiency of air conditioning in a server room without lowering the air conditioning efficiency in the server room even when an empty rack is present in the server room.

  As a technical means for achieving the above object, the air conditioning efficiency structure in the server room according to the present invention is such that a server is installed in a server room in which a plurality of racks that can accommodate a plurality of servers are arranged in a line. In the structure for improving the efficiency of air conditioning in a server room where empty racks that are not accommodated exist, a cover member is placed on the side plate on which the opening and taking-out of the empty rack servers and the through holes are formed. It is characterized by sealing the rack.

  Hot air discharged from the rack by cooling a server in the rack near the empty rack does not flow into the empty rack by the shielding sheet. Therefore, the flow path of the conditioned air can be ensured in a state according to the design of the server room.

  In addition, the air conditioning efficiency structure in the server room according to the invention of claim 2 is a server room in which a plurality of racks that can accommodate a plurality of servers are arranged in a row, and a shelf board installed in the rack is provided. In an air conditioning efficiency structure in a server room where a partially empty rack in which a server is accommodated only in part exists, an opening facing the empty shelf board in which the server is not installed in the partially empty rack; A portion of the side plate in which the through holes are formed facing the empty shelf plate is covered with a shielding member to seal the upper portion of the empty shelf plate.

  This prevents hot air from flowing into empty shelves that do not contain servers when some empty racks exist. That is, hot air that has cooled servers in nearby racks is prevented from flowing into the space above the empty shelves, and cold air is allowed to flow into the space above the shelves on which the servers are placed. The server can be allowed to cool.

  According to the structure for improving the efficiency of air conditioning in the server room according to the present invention, the conditioned air is not allowed to flow into the empty rack, so that the air conditioning efficiency at the time of design can be secured and the air conditioning efficiency of the server room is not lowered. .

  Further, according to the air conditioning efficiency structure in the server room according to the invention of claim 2, even if there is a partially empty rack in which a server is not accommodated in part, a portion of the empty shelf board Since the conditioned air does not flow into the air conditioner, the design air conditioning efficiency can be ensured.

It is a perspective view of the rack provided with the efficiency improvement structure of the server room which concerns on this invention. The figure explaining the flow of the air-conditioning air when the rack provided with the efficiency improvement structure of the air conditioning in the server room concerning this invention is installed, and shows the relationship with the rack. It is a perspective view of the partially empty rack showing a case where the structure for improving the efficiency of air conditioning in the server room according to the present invention is implemented for a partially empty rack in which a server is accommodated in part. of It is a figure explaining the flow of the conditioned air in the case of the partially empty rack shown in FIG. 3, and has shown the relationship with a rack. It is a figure explaining the flow of conditioned air through the rack in which the server is accommodated. It is a figure explaining the flow of the conditioned air in case an empty rack exists. It is a schematic perspective view which shows an empty rack. It is a perspective view which shows the state in which the shelf board was installed in the rack.

  Hereinafter, based on the preferred embodiment shown in the drawings, a structure for improving the efficiency of air conditioning in a server room according to the present invention will be specifically described.

  As shown in FIG. 1, the opening is covered by covering the opening on the front surface of the empty rack 1 a with a shielding sheet 2 that is a shielding member made of a light-transmitting vinyl material or the like. Further, the shielding sheet 2 is wound around the other side plate of the empty rack 1a where the through holes are formed by punching metal or the like to shield the through holes, and the empty rack 1a is Blockade. In order to fix the shielding sheet 2 to the empty rack 1a, for example, a hook-and-loop fastener is attached to the empty rack 1a and the shielding sheet 2 and the adhesive action of the hook-and-loop fastener is used, or an attachment hole is formed in the shielding sheet 1a. Can be used to make use of punched metal through holes in the empty rack 1a.

  As shown in FIG. 2, even if hot air Ah used for cooling the server of the nearby rack 1 flows into the empty rack 1a provided with the shielding sheet 2, it is blocked by the shielding sheet 2. Inflow is prevented. For this reason, the warm air Ah rises and is sucked through an opening (not shown) formed on the ceiling surface and returned to the air conditioner. For this reason, it does not affect the fluctuation of the air conditioning efficiency of the server room and does not reduce the air volume efficiency.

  As shown in FIG. 8 described above, racks 11 are installed in the rack 1 in accordance with the number of servers accommodated, and the servers are installed in a state of being mounted on the racks 11. FIG. 3 shows a partially empty rack 1b in which a server (not shown) is installed on the second shelf 11 and the air conditioning efficiency structure in the server room according to the present invention is shown for this partially empty rack 1b. It is a figure explaining the state to implement. The first stage, the third stage, and the fourth stage are empty shelves 11a on which no servers are placed, and the hot air Ah that has been heated up by cooling the server in the nearby rack 1 is these empty shelves. There is a risk of flowing into the space above the plate 11a. For this reason, in order to block these spaces, the covering sheet 3 as a shielding member is covered with the opening facing the space above the empty shelf board 11a, and the side plate facing the space is formed with a through hole. Then, the shielding sheet 3 is wound.

  As a result, as shown in FIG. 4, cold air Ac flows into a server (not shown) installed on the second shelf 11 and cools the server, and then is partially discharged from the back of the empty rack 1b. . On the other hand, neither the cold air Ac nor the hot air Ah flows into the empty shelf board 11a by the shielding sheet 3, and the flow of conditioned air is not hindered.

  The shielding sheet 2 may be made of resin such as vinyl, or may be a lightweight plate material.

  According to the present invention, even in a server room where there is an empty rack in which no server is accommodated, it is possible to pass a desired flow path without causing conditioned air to stay. This contributes to the effective use of energy without reducing the air conditioning efficiency.
