Description

本発明は、各種機器を収納するためのキャビネットラックに関するものである。   The present invention relates to a cabinet rack for storing various devices.

近年、サーバー等の通信機器は、高容量でコンパクトな設計が主流であり、通信機器が密集して小さなスペースに収納されるため、排熱が大きな課題となっている。機器の排熱効率を上昇させるため小型で回転数の高いファンを用いることがあるが、騒音が大きく、静かなオフィス等に設置したキャビネットラックからの音漏れも問題となっていた。   In recent years, communication devices such as servers are mainly designed with a high capacity and a compact design. Since communication devices are concentrated and stored in a small space, exhaust heat has become a major issue. In order to increase the exhaust heat efficiency of the equipment, a small fan with a high rotation speed is sometimes used. However, noise is loud and sound leakage from a cabinet rack installed in a quiet office has been a problem.

音漏れの対策として、吸音材をキャビネットのパネル内側に貼付し、キャビネット内部で発生する音を全体的に吸音して、外部へ漏れないようにしていた。   As a measure against sound leakage, a sound-absorbing material is attached to the inside of the cabinet panel to absorb the sound generated inside the cabinet and prevent it from leaking outside.

基本的には密閉性を高めてキャビネット31の内側から外側への空気の移動を減らすことが良いと考えられている。そのため、扉体を二重構造とし、一重目は上下を開放状態としそこに吸気ファンを扉体に取り付け、吸気する方法があった。   Basically, it is considered that it is good to improve the sealing property and reduce the movement of air from the inside to the outside of the cabinet 31. Therefore, there has been a method in which the door body has a double structure, the first is opened up and down, an intake fan is attached to the door body, and the air is sucked.

また、扉体には吸気口を設けず、キャビネット31の背面下部にスリットを設け吸気し、上部には排気ファンを取り付け排気していた。

In addition, the door body is not provided with an air inlet, and a slit is provided at the lower back of the cabinet 31 to intake air, and an exhaust fan is attached to the upper portion to exhaust air.

しかしながら、上記従来技術におけるキャビネットラックでは、収納されている機器により発生する音は、パネルに到達したときに、パネル内側に貼付された吸音材で吸音される。音源となる機器からパネルに到達するまでに音は拡散されており、吸音効果があまり高くない。また、その拡散された音は、他のものと共鳴し高音となるので耳障りであり、オフィス内での騒音が問題になりやすかった。   However, in the cabinet rack according to the above-described prior art, the sound generated by the stored equipment is absorbed by the sound absorbing material attached to the inside of the panel when it reaches the panel. The sound is diffused from the sound source device to the panel, and the sound absorption effect is not so high. Further, the diffused sound resonates with others and becomes high-pitched sound, which is annoying and noise in the office tends to be a problem.

そこで本発明は、簡単な構造で、確実に外部への音漏れを防止するキャビネットラックを提供することを目的とし、その構造は、キャビネットラックの本体は、四方をパネルで被覆すると共にさらに本体内側に内パネルを設け、パネル内側に吸音材を貼付し、内パネルは一部吸音材を用い、キャビネットラック内部から外部へ漏れる音を抑制することを特徴とする。   Therefore, the present invention has an object to provide a cabinet rack that has a simple structure and reliably prevents sound leakage to the outside. The structure of the cabinet rack is such that the cabinet rack is covered with panels on all sides and further inside the body. An inner panel is provided, a sound absorbing material is affixed to the inside of the panel, and a part of the inner panel uses a sound absorbing material to suppress sound leaking from the inside of the cabinet rack to the outside.

本発明に係るキャビネットラックは、キャビネットラックの本体は、四方をパネルで被覆すると共にさらに本体内側に内パネルを設け、パネル内側に吸音材を貼付し、内パネルは一部吸音材を用いるため、音源となる機器の近くで吸音するため、音が拡散される前に吸音でき、吸音効果を高めることができる。また、吸音材は、キャビネットラックのパネルと内パネルとに貼付され、二重の吸音構造となるため、吸音率が向上し、キャビネットラックの外側への音漏れを確実に抑えることができる。   In the cabinet rack according to the present invention, the main body of the cabinet rack is covered with panels on four sides, and further provided with an inner panel on the inner side of the main body, and a sound absorbing material is affixed to the inner side of the panel. Since sound is absorbed near the sound source device, sound can be absorbed before the sound is diffused, and the sound absorption effect can be enhanced. Further, since the sound absorbing material is affixed to the cabinet rack panel and the inner panel and has a double sound absorbing structure, the sound absorption rate is improved, and sound leakage to the outside of the cabinet rack can be reliably suppressed.

本発明に係るキャビネットラックの実施例を図1〜図3の添付図面に基いて説明する。   An embodiment of a cabinet rack according to the present invention will be described with reference to the accompanying drawings of FIGS.

キャビネットラック1は本体2の四方側面をパネル3で被覆して構成される。キャビネットラック1にはマウントアングル4を設け、通信機器や電気機器はこのマウントアングル4に固定されて本体2に収納される。   The cabinet rack 1 is configured by covering the four sides of the main body 2 with a panel 3. The cabinet rack 1 is provided with a mount angle 4, and communication equipment and electrical equipment are fixed to the mount angle 4 and stored in the main body 2.

キャビネットラック1の側面にはパネル3の内側に内パネル5を取り付ける。内パネル5は、本体2に取り付け可能であり、マウントアングル4やマウントアングル4に固定される機器に干渉しないような構造とする。   An inner panel 5 is attached to the inside of the panel 3 on the side surface of the cabinet rack 1. The inner panel 5 can be attached to the main body 2 and has a structure that does not interfere with the mount angle 4 or a device fixed to the mount angle 4.

パネル3の内側には吸音材6を貼付する。また、内パネル5は、一部を吸音材7で構成するか、または内パネル5の内側に吸音材7を貼付するなど、吸音材7を用いて構成するものとする。特に吸音材7を用いる位置は、キャビネットラック1に収納される機器が音を発する場所に近い位置とする。   A sound absorbing material 6 is attached to the inside of the panel 3. In addition, the inner panel 5 is configured by using the sound absorbing material 7 such as a part of the sound absorbing material 7 or by attaching the sound absorbing material 7 to the inside of the inner panel 5. In particular, the position where the sound absorbing material 7 is used is a position close to the place where the equipment stored in the cabinet rack 1 emits sound.

音は音源から離れるに従って広い範囲に拡散されてしまう。音が拡散されることで他の機器やキャビネットラック1の本体2に振動となって伝わり、共鳴を起こしさらに騒音となっている。本発明におけるキャビネットラック1において、音源近くに吸音材7を用いた内パネル5を設け、キャビネットラック1内部に拡散されてしまう前の、音を吸音する。そのため、吸音効果を高めることができ、キャビネットラック1外部への音の漏れを最小限に抑えることができる。また、キャビネットラック1の側面に設けたパネル3にも吸音材6を貼付できるので、吸音構造が二重となり、吸音率をさらに上げている。   The sound spreads over a wider area as you move away from the sound source. As the sound is diffused, it is transmitted to other equipment and the main body 2 of the cabinet rack 1 as vibration, causing resonance and further noise. In the cabinet rack 1 according to the present invention, the inner panel 5 using the sound absorbing material 7 is provided near the sound source to absorb the sound before being diffused into the cabinet rack 1. Therefore, the sound absorption effect can be enhanced, and leakage of sound to the outside of the cabinet rack 1 can be minimized. In addition, since the sound absorbing material 6 can be attached to the panel 3 provided on the side surface of the cabinet rack 1, the sound absorbing structure is doubled and the sound absorbing rate is further increased.

内パネル5は上記構造に限定されるものではなく、適宜開口8を設けることで、通線可能としたり、また通気性を良くし、温度上昇を抑えることもできる。   The inner panel 5 is not limited to the above structure, and by providing the opening 8 as appropriate, the inner panel 5 can be connected, can improve air permeability, and can suppress an increase in temperature.
